     BACKGROUND 
     A sensor may be configured (e.g., designed) to measure one or more environmental characteristics, for example, temperature, humidity, ambient noise, carbon dioxide, and/or other aspects of an ambient environment. There may arise a need to know whether one or more bodily characteristics of an individual are abnormal such that they are indicative of an illness. For example, it may be beneficial to know if an individual has a bodily temperature above normal in various settings. For example, in a private setting such as a home. For example, in non-private setting such as in a workplace, hospital, airport, restaurant, or a correctional facility (e.g., jail or prison). Such need may arise in consideration of any potential harm that a diseased person may inflict on others. Individuals may test themselves for fever when they are aware or suspect such increased bodily temperature in themselves, for example, when they are distinctly uncomfortable. In some settings, an institution may have an incentive to prevent ill occupants in its institution. For example, an industrial kitchen may wish to prevent presence of ill employees handling any food items, e.g., distributed to the general public. At times it may be challenging to detect in ill person, e.g., having abnormal characteristics. For example, due to an awareness level of the individual, and/or due to a hindrance of the individual to divulge such information. 
     At times, it may be challenging to accurately detect an abnormal bodily characteristic (e.g., fever) for a person, when bodily characteristics vary (e.g., widely) among people. A sensor which is deployed for measuring the bodily characteristic may not be calibrated and/or may require daily calibration, which may be expensive and/or inconvenient. Moreover, certain bodily characteristics may have natural variations which are not indicative of an abnormality. Once an abnormality is detected, additional challenges may arise from attempts to track interactions of an affected person and notify potentially exposed individuals for contact tracing purposes while maintaining privacy and securing of data. At times, offering a route that reduces once&#39;s exposure to other occupants in an enclosure, may be advantageous, e.g., in reducing infections among individuals. 
     SUMMARY 
     Various aspects disclosed herein alleviate at least part of the one or more shortcomings related to bodily characteristic(s) of an individual. 
     Various aspects disclosed herein relate to one or more sensors disposed in an environment having occupant(s). The sensor(s) sense various characteristics of the environment, for example, environmental characteristics that influenced by the individual(s) in the facility (e.g., having the enclosure). For example, a temperature sensor, a carbon dioxide sensor, a humidity sensor, and/or a sensor sensing volatile organic compounds, may be influenced by presence of individual(s) in the facility (e.g., having the enclosure). The environment in the facility (e.g., having the enclosure) may be mapped by sensor(s) in the facility (e.g., having the enclosure). A characteristic of the environment may have gradients, e.g., around and/or as a consequence of a presence of an individual in the environment. For example, the environment may show trends of the environmental characteristic using a thermal array of sensors. The environment may be a normal setting, for example, a workplace, an airport, a restaurant. The environment may be a dedicated inspection environment, e.g., that permits a single individual to be tested therein. The individual may be stationary or non-stationary during the testing. For example, the individual may be passing through the sensed environment, e.g., during the testing. 
     Various aspects disclosed herein relate to a use of relative bodily characteristics (e.g., temperature) measurements by a sensor. In some embodiments, an evaluation of relative changes of a characteristic (e.g., as opposed to making determinations based on an absolute magnitude) is used, e.g., because a temperature sensor need not measure an occupant&#39;s absolute temperature accurately in order to accurately measure a relative difference of temperature measurements taken at different times. The sensor may read 100° F. where the actual temperature of the occupant is 98.6° F. However, a particular sensor (e.g., even if not calibration) may be consistent in measuring variation accurately (e.g., within a measurement error). For example, a deviation in a later measured temperature of +3° F. from 100° F. The sensor can be in a high traffic area of a building (e.g., bathroom entrance, office entrance) and can read the bodily characteristic (e.g., forehead temperature) of a person, and broadcast the temperature (e.g., via an electromagnetic beacon), to a receiver via a communication network. The communication network can be communicatively coupled to a phone application (e.g., if the application is kept activated, without requiring identification of the person), or to a control system of the building. The control system may require identification (ID) of the person. The identification may be general (e.g., excluding personally identifiable information (PII)). The identification may be a unique identifier. A storage device can store the sensor reading along with an ID of the sensor. A person having (e.g., substantially) the same bodily characteristic can get tested at different locations in the facility (e.g., having the enclosure) (e.g., building) on the same day and get different readings (e.g., because of the different sensor calibration statuses). Over time (e.g., over a time period), the stored sensor readings corresponding to a particular sensor can be compared to analyze a bodily characteristic according to relative changes. 
     Various aspects disclosed herein relate to artificial intelligence (e.g., machine-learning) software on an application (app) and/or control system, which may learn over a period of time (e.g., a month) what is the typical bodily temperature of that person (e.g., for a plurality of sensors in the facility (e.g., having the enclosure) with which the individual interacted over the period). In some embodiments, if the person develops an abnormal bodily characteristic (e.g., fever), the abnormality will be detected, can be logged and/or trigger an event. For example, if the bodily characteristic passes a threshold (e.g., if the bodily temperature is more than 3° F. from normal readings). 
     Various aspects disclosed herein relate to the use of contact tracing to trace contact of a person identified as being potentially infected (e.g., having abnormal bodily characteristic as measured in the facility (e.g., having the enclosure), or otherwise reported as testing positive as to the abnormal bodily characteristic and/or ailment). 
     In another aspect, a method for detecting bodily characteristic of an individual in a facility (e.g., having an enclosure) comprises: (a) using at least one sensor to sense and/or identify an environmental characteristic of an environment in presence of the individual, which environmental characteristic is detectibly perturbed by the presence of the individual, as compared to absence of the individual from the environment; (b) analyzing (i) the sensed environmental characteristic in relation to (ii) a threshold indicative of abnormal bodily characteristic, to generate an analysis; and (c) using the analysis to generate a report of presence or absence of the indication of abnormal bodily characteristic of the individual. 
     In some embodiments, the environmental characteristic comprises temperature, carbon dioxide, humidity, or volatile organic compounds. In some embodiments, the bodily characteristic comprises fever, breathing, or perspiration. In some embodiments, the environment comprises an environment internal to the facility (e.g., having the enclosure) or an environment at an opening of the facility (e.g., having the enclosure).

     In some embodiments, the enclosure comprises one or more openings. The one or more openings may be reversibly closable. The one or more openings may be permanently open. A fundamental length scale of the one or more openings may be smaller relative to the fundamental length scale of the wall(s) that define the enclosure. A fundamental length scale may comprise a diameter of a bounding circle, a length, a width, or a height. The fundamental length scale may be abbreviated herein as “FLS.” A surface of the one or more openings may be smaller relative to the surface the wall(s) that define the enclosure. The opening surface may be a percentage of the total surface of the wall(s). For example, the opening surface can measure about 30%, 20%, 10%, 5%, or 1% of the walls(s). The wall(s) may comprise a floor, a ceiling or a side wall. The closable opening may be closed by at least one window or door. The enclosure may be at least a portion of a facility. The enclosure may comprise at least a portion of a building. The building may be a private building and/or a commercial building. The building may comprise one or more floors. The building (e.g., floor thereof) may include at least one of: a room, hall, foyer, attic, basement, balcony (e.g., inner or outer balcony), stairwell, corridor, elevator shaft, façade, mezzanine, penthouse, garage, porch (e.g., enclosed porch), terrace (e.g., enclosed terrace), cafeteria, and/or Duct. In some embodiments, an enclosure may be stationary and/or movable (e.g., a train, a plane, a ship, a vehicle, or a rocket). 
     In some embodiments, the enclosure encloses an atmosphere. The atmosphere may comprise one or more gases. The gases may include inert gases (e.g., argon or nitrogen) and/or non-inert gases (e.g., oxygen or carbon dioxide). The enclosure atmosphere may resemble an atmosphere external to the enclosure (e.g., ambient atmosphere) in at least one external atmosphere characteristic that includes: temperature, relative gas content, gas type (e.g., humidity, and/or oxygen level), debris (e.g., dust and/or pollen), and/or gas velocity. The enclosure atmosphere may be different from the atmosphere external to the enclosure in at least one external atmosphere characteristic that includes: temperature, relative gas content, gas type (e.g., humidity, and/or oxygen level), debris (e.g., dust and/or pollen), and/or gas velocity. For example, the enclosure atmosphere may be less humid (e.g., drier) than the external (e.g., ambient) atmosphere. For example, the enclosure atmosphere may contain the same (e.g., or a substantially similar) oxygen-to-nitrogen ratio as the atmosphere external to the enclosure. The velocity of the gas in the enclosure may be (e.g., substantially) similar throughout the enclosure. The velocity of the gas in the enclosure may be different in different portions of the enclosure (e.g., by flowing gas through to a vent that is coupled with the enclosure). 
     Certain disclosed embodiments provide a network infrastructure in the enclosure (e.g., a facility such as a building). The network may be installed when an envelope of an enclosure (e.g., a building) is constructed, and/or before an interior of the enclosure is constructed. The network may comprise wiring (e.g., cables) residing in the envelope of the enclosure (e.g., external walls of the enclosure such as a building). The network infrastructure is available for various purposes such as for providing communication and/or power services. The communication services may comprise high bandwidth (e.g., wireless and/or wired) communications services. The communication services can be to occupants of a facility and/or users outside the facility (e.g., building). The network infrastructure may work in concert with, or as a partial replacement of, the infrastructure of one or more cellular carriers. The network infrastructure can be provided in a facility that includes electrically switchable windows. Examples of components of the network infrastructure include a high speed backhaul. The network infrastructure may include at least one cable, switch, physical antenna, transceivers, sensor, transmitter, receiver, radio, processor and/or controller (that may comprise a processor). The network infrastructure may be operatively coupled to, and/or include, a wireless network. The network infrastructure may comprise wiring. One or more sensors can be deployed (e.g., installed) in an environment as part of installing the network and/or after installing the network. The network may be an encrypted network. The network may comprise one or more levels of encryption. 
     In some embodiments, the network infrastructure is operatively coupled to one or more sensors disposed in the enclosure. The sensor(s) may be configured to detect an environmental characteristic influenced by an individual present in the enclosure, and/or any gradient of that characteristic in the environment. The sensor may be able to sense and/or identify an abnormal influence on that environmental characteristic by the individual (e.g., excessive heat, perspiration, VOC, and/or carbon dioxide emission). In some embodiment, the sensor is configured to sense and/or identify one or more bodily characteristics emitted and/or expelled (e.g., directly) from the individual (e.g., heat, perspiration (e.g., humidity), VOCs (e.g., odor), and/or carbon dioxide). The bodily characteristic may comprise sebum, or urine. The VOCs can be reaction product(s) of compounds excreted by the individual. For example, formaldehyde, or (e.g., cyclic) methylsiloxane. In some embodiment, the sensor is configured to sense and/or identify one or more bodily characteristics of the individual (e.g., directly sense the individual). The sensor may be operatively coupled to a network (e.g., the network infrastructure disclosed herein). The sensed data may be analyzed and/or recorded. The analyzed data may be utilized to provide a report and/or alert. For example, the analyzed data may send an alert if the sensed data confines to a rule. The rule may comprise if the data is outside a threshold window, inside a threshold window, above a threshold, or below a threshold. The threshold may be a value or a function. The threshold may evolve in time, e.g., as more data emerges. The rule may be predetermined, e.g., by a user, by a third party, by a global and/or jurisdictional standard, or by any combination thereof. 
     In some embodiments, the abnormal bodily characteristic is related to an illness. The illness may relate to an inflammation. The illness may comprise pathogen (e.g., bacterial or viral) related infections. The pathogen may cause common cold, pneumonia or flu like symptoms. The pathogen may include streptococcus. The pathogen may comprise rhino, influenza, or corona virus. The illness may relate to an epidemic. The illness may relate to a respiratory and/or inflammatory disease. The illness may relate to an epithelial tissue and/or neuronal infectious disease. The illness may relate to a severe and/or acute disease. The illness may relate to nose, ear and/or throat infections. The illness may be contagious (e.g., by individuals). The illness may infect the bronchia and/or lungs. The illness may infect one or more internal organs and/or blood. The illness may comprise pneumonia, or flu. The illness may be caused by microorganisms, e.g., that invade at least one bodily tissue. The illness may be contagious having an Ro factor of at least about 0.5, 1, 1.5, 2, 2.5, or 3. 
     In some embodiments, one or more sensors may transmit the analyzed data, report and/or alert. The transmission may be to an individual and/or to a user. For example, the report may be transmitted to a party of interest. The party of interest may be an establishment head, a facility owner, a user, a tested individual. The data may be saved, analyzed and/or reported in compliance with jurisdictional rules and regulations. The report, notice, alert, and/or data may be transmitted to wired and/or wireless device (e.g., cell phone). For example, an individual tested may receive a sound, vibration, picture or written notice (e.g., alert). The transmission may comprise an encoding. The encoding may comprise one signal for an abnormal characteristic (e.g., suggesting an ill individual), and a second signal for a normal characteristic (e.g., suggesting a healthy individual). For example, a cell phone of a person my vibrate once when a temperature sensor does not sense an elevated temperature for the person and vibrate twice when the temperature sensor senses an elevated temperature for the person. 
     In some embodiments, the sensor(s) are disposed in an environment. A sensor may be attached to (or disposed in) at least one wall, ceiling, or floor of an enclosure. In an example, the sensor or an ensemble of sensors may dispose on the floor or in the floor. The ensemble of sensors may comprise a weight sensor, a movement sensor, and accelerometer, an audio sensor, or an optical sensor. At least one sensor in the ensemble may be able to sense and/or identify a presence of an individual, e.g., by sensing a person&#39;s weight, by sensing a person&#39;s sound, by sensing a person&#39;s obstruction of light, by sensing an approaching object associated with the person. For example, when an individual resides on a platform coupled to a weight sensor, the weight sensor may be able to sense and/or identify a weight associated with an individual. For example, when an individual obstructs a light ray (e.g., IR light ray) sensed by an optical sensor, the optical sensor may be able to sense and/or identify the obstruction of light. A requested position of the individual (e.g., testing station) may be marked on the floor (e.g., in a form of a shape such as a circle, square, or the letter X). The sensor(s) may be mounted on the door (e.g., door frame), or on the window (e.g., window frame). The enclosure may facilitate testing of a single individual or a plurality of individuals. There may be a single testing station (e.g., a kiosk) disposed in an enclosure, or a plurality of testing stations. Testing stations of the plurality of testing stations may be sufficiently distant to prevent contamination between individuals in the same room (e.g., prevents inter-contamination of individuals). The distance may be predefined and/or adjusted and/or defined per jurisdictional, global, and/or third party standards. The person may freely walk over and/or past the designated testing area or stay there for a time. The time in which the individual may be required to remain (e.g., substantially) stationary on the testing area may be at most about 1 second (sec), 3 sec, 5 sec, 10 sec, 30 sec, or 60 sec. The time in which the individual may be required to remain (e.g., substantially) stationary on the testing area may be any value between the aforementioned values (e.g., from about 1 sec to about 60 sec, from about 1 sec, to about 5 sec, from about 5 sec to about 30 sec, or from about 30 sec to about 60 sec). An individual may pass by the sensor(s) and be tested on every passing. This may allow for automatic testing of an individual multiple times in a single day, depending on how many times the individual passes by the testing station (e.g., by the sensor(s)). A plurality of test results may increase confidence in the results, reduce error values, and/or enable identification of relative changes between test results obtained at different times. If any of the sensors have a high fidelity, the sensor(s) may be able to provide information of trends of the characteristic in the individual in absolute and/or relative terms, e.g., over periods of time such as at least an hour, a day, a week, a month, or a year. If a sensor is uncalibrated or uncalibratable, and the sensor results are consistent over periods of usage, then the sensor may be able to provide information of trends of the characteristic in the individual in relative terms, e.g., over periods of time such as at least an hour, a day, a week, a month, or a year. 
       FIG.  1 A  shows a vertical cross sectional example of an enclosure  100  (e.g., a room) with an individual  101  therein, which enclosure has an environment  102  (e.g., atmosphere) and a testing platform  111 . The enclosure has an ingress direction  104  and an egress direction  105 . The individual can enter the enclosure from the ingress direction and exit the enclosure through the egress direction. The individual  102  can wait on the testing platform  111  for sensor(s) to sense and/or identify the environmental characteristic for a period of time (e.g., as indicated herein), or naturally walk by the testing station. The individual  102  may have a communication device  106  to which the analysis of the test may be communicated. the communication device may be communicatively coupled to a network (e.g., network infrastructure) of the facility in which the enclosure is disposed. The communication device may be a mobile device (e.g., cell phone, iPad, or laptop). The communication device may be a hand-held device. The network may be configured to support at least fourth or fifth generation cellular network communication. 
     The testing station (e.g., kiosk) may contain one or more sensors, e.g., that perform the environmental position and/or detect the presence of the individual. The testing station may be devoid of at least a sensor that perform the environmental position. The testing station may be devoid of at least a sensor that detect the presence of the individual. For example, a weight sensor may detect the presence of the individual and be disposed in testing platform. The temperature sensor that may detect the temperature of the environment in the enclosure may be disposed in the testing platform, or elsewhere in the enclosure. For example, an optical sensor (e.g., sensor sensitive to electromagnetic radiation such as in the infrared and/or visible range) may detect the presence of the individual and be disposed in the enclosure outside of the platform (e.g., not in the testing platform). The platform may be devoid of the one or more sensors. The testing platform may direct the individual where to position in order for the testing to be (e.g., optimally) performed. The ingress and/or ingress to the enclosure (e.g., doors) may be closed during testing. The sensor(s) may be disposed at a fixture of a facility (e.g., testing station, entrance hall, or conference room). The fixture may comprise a framing, a wall, a ceiling, or a floor. The framing may comprise a door framing or a window framing. 
     In some embodiments, an occupancy sensor is operatively coupled to the network. The occupancy sensor may be configured to sense and/or identify motion of, electromagnetic radiation associated with, and/or identification tag of, an occupant in the facility (or entering the facility). For example, the sensor may comprise a visible or an IR sensor. At times, the occupancy sensor may be unable to identify an identity of the occupant. The IR sensor may detect heat signature characteristic of individuals. The IR sensor may be part of a sensor system (e.g., a device ensemble). Data of the IR sensor may be integrated with visible data and/or motion data. The sensor system may be operatively coupled to the network and/or to the control system of the facility. The occupancy sensor (e.g., as part of the sensing system) may be utilized to determine density of individuals in an enclosure of the facility in which the occupancy sensor(s) is disposed and/or user of the enclosure by occupants (e.g., over time). The occupancy sensor may be operatively coupled to at least one processor. The occupancy sensor may be configured to detect movement of occupants. For example, the occupancy sensor may detect electromagnetic radiation emitted by and/or reflected from an occupant (e.g., IR radiation such as forming a heat signature of the individual), which detention may occur overtime. In some embodiments, using the occupancy sensor (e.g., as part of a sensor system such as a device ensemble) comprises measuring at a rate of at least about every 2 seconds (sec), 1 sec, 0.5 sec, 0.25 sec, 0.2 sec, 0.15 sec, 0.1 sec, 0.05 sec, or 0.025 sec. The occupancy sensor may comprise a camera. The camera may be configured to take at least about 30 frames per second (frm/sec), 20 frm/sec, 10 frm/sec, 8 frm/sec, 6 frm/sec, 4 frm/sec, or 2 frm/sec. The frequency of sensing (e.g., the number of measurements per second taken, such as the number of frames per seconds taken) may be adjusted (e.g., manually and/or automatically using at least one controller, e.g., as part of the control system). The camera may comprise an IR and/or a visible camera. The sensor system may be configured to detect a location of the occupant, e.g., relative to the facility, relative to the enclosure in which it is disposed, and/or in absolute coordinates (e.g., using a GPS or any other anchored geo-location technology). Detection of the occupant overtime and space may be utilized to determine a movement (e.g., including a movement direction) of the occupant. The movement direction of the occupant may comprise utilizing a tracking algorithm.

The tracking algorithm may be a tracking algorithms such as is disclosed in “Simple object tracking with OpenCV” by Adrian Rosebrock published on Jul. 23, 2018 and available at https://www.pyimagesearch.com/2018/07/23/simple-object-tracking-with-opencv, which is incorporated herein by reference in its entirety. 
       FIG.  1 B  shows a vertical cross sectional example of an enclosure  150  (e.g., a room) with individuals  151 ,  152 , and  153  therein, which enclosure has an environment  170  (e.g., atmosphere) and testing platforms  161 ,  162 ,  162  above which the individuals stand and/or pass. The enclosure has an ingress direction  181  and an egress direction  182 . The individual can enter the enclosure from the ingress direction and exit the enclosure through the egress direction through openings (e.g., doors).  FIG.  2 A  shows a vertical cross sectional example of an enclosure  200  (e.g., a room) with an individual  201  therein, which enclosure has an environment  202  (e.g., atmosphere) and sensor(s)  211 . The enclosure has an ingress direction  204  and an egress direction  105 . The individual can enter the enclosure from the ingress direction and exit the enclosure through the egress direction. The individual  202  can enter through an opening (e.g., door) onto which the sensor(s)  211  attaches, so that sensor(s) can sense the environmental characteristic. The individual can naturally walk by the sensor(s)  211  or wait there for a period. The individual  202  may have a communication device  206  to which the analysis of the test may be communicated. 
       FIG.  2 B  shows a vertical cross sectional example of an enclosure  250  (e.g., a room) with individuals  251 ,  252 , and  253  therein, which enclosure has an environment  270  (e.g., atmosphere) and sensor(s)  261 . The individuals  251 ,  252 , and  253  can enter through an opening (e.g., door) onto which the sensor(s)  261  attaches, so that sensor(s) can sense the environmental characteristic. The enclosure has an ingress direction  281  and an egress direction  282 . The individual can enter the enclosure from the ingress direction and exit the enclosure through the egress direction through openings (e.g., doors). 
     In some embodiments, the control system is operatively (e.g., communicatively) coupled to an ensemble of devices (e.g., sensors and/or emitters). The ensemble facilitates the control of the environment and/or the alert. The control may utilize a control scheme such as feedback control, or any other control scheme delineated herein. The ensemble may comprise at least one sensor configured to sense and/or identify electromagnetic radiation. The electromagnetic radiation may be (humanly) visible, infrared (IR), or ultraviolet (UV) radiation. The at least one sensor may comprise an array of sensors. For example, the ensemble may comprise an IR sensor array (e.g., a far infrared thermal array such as the one by Melexis). The IR sensor array may have a resolution of at least 32×24 pixels, or 640×480 pixels. The IR sensor may be coupled to a digital interface. The ensemble may comprise an IR camera. The ensemble may comprise a sound detector. The ensemble may comprise a microphone. The ensemble may comprise any sensor and/or emitter disclosed herein. The ensemble may include CO 2 , VOC, temperature, humidity, electromagnetic light, pressure, and/or noise sensors. The sensor may comprise a gesture sensor (e.g., RGB gesture sensor), an acetometer, or a sound sensor. The sounds sensor may comprise an audio decibel level detector. The sensor may comprise a meter driver. The ensemble may include a microphone and/or a processor. The ensemble may comprise a camera (e.g., a 4K pixel camera), a UWB sensor and/or emitter, a UHF sensor and/or emitter, a Bluetooth (abbreviated herein as “BLE”) sensor and/or emitter, a processor. The camera may have any camera resolution disclosed herein. One or more of the devices (e.g., sensors) can be integrated on a chip. The sensor ensemble may be utilized to determine presence of occupants in an enclosure, their number and/or identity (e.g., using the camera). The sensor ensemble may be utilized to control (e.g., monitor and/or adjust) one or more environmental characteristics in the enclosure environment. 
     The sensor(s) attached to the opening (e.g., door and/or window) by which the individual passes, may contain one or more sensors. The one or more sensors may perform the environmental position and/or detect the presence of the individual. The sensor(s) attached to the opening may be devoid of at least a sensor that perform the environmental position. The sensor(s) attached to the opening may be devoid of at least a sensor that detect the presence of the individual. For example, an environmental characteristic influenced by the individual (e.g., temperature) may be disposed in the sensor(s) attached to the opening or disposed elsewhere in the enclosure. For example, a sensor that senses the presence of the individual (e.g., optical sensor) may be attached to the opening, or disposed elsewhere in the enclosure. The system detecting an environmental characteristic(s) influenced by an individual may be devoid of any sensor that does not detect environmental characteristic(s). A sensor that does not detect environmental characteristic(s) may detect a presence of an individual (e.g., a weight sensor, or a camera). In some embodiments, a sensor that detects an environmental characteristic also detects the presence of an individual (e.g., infrared sensor, humidity sensor, or carbon dioxide sensor). In some embodiments, one or more openings in the enclosure remain open at least in part during the testing. For example, a door may be kept open while the sensors sense the temperature of an environment of the opening (e.g., and thus any perturbation thereof). The perturbation may be caused by an individual. An individual may have a typical manner of perturbing an environmental characteristic (e.g., within normal and/or abnormal range). In some embodiments, sensor(s) detecting whether a person influences an environmental change indicative of normal and/or abnormal personal characteristics is sufficient, e.g., and there is no additional requirement for a sensor dedicated to indicating presence or absence of the individual. For example, high fidelity (e.g., high resolution) sensors measuring a personal characteristic may be sufficient. For example, a sensor that (e.g., markedly) perturbs an ambient environmental characteristic may be sufficient. A high fidelity sensor may have more than one single pixel detector. A high fidelity sensor may comprise a plurality (e.g., an array) of single pixel detectors. A high fidelity sensor may be configured to detect a span of values of the detectable properties. For example, an amplitude span (e.g., range). For example, a wavelength span (e.g., including a plurality of wavelengths). For example, a thermal detector may be an optical detector (e.g., an infrared (IR) detector), and may be able to detect a plurality of IR wavelengths (e.g., within a wavelength range). A marked perturbation may have a high signal to noise ratio that is detectibly different from a signal at ambient conditions. In some embodiments, sensor(s) detecting the environmental characteristic (e.g., temperature) form an array of sensors. The array of sensors may be included in an ensemble. The ensemble and/or sensor(s) therein may have a small FLS, small form factor (e.g., volume to height ratio), may be of low cost, may be Bluetooth enabled (e.g., comprise a Bluetooth adaptor), and/or require low power. The small FLS may be of at most about 20 millimeters (mm), 10 mm, 8 mm, 6 mm, 5 mm, 4 mm, 3 mm, 2 mm or 1 mm. The small FLS may be of any value between the aforementioned values (e.g., from about 20 mm to about 1 mm, from about 20 mm to about 8 mm, or from about 8 mm to about 1 mm). The low power required by the ensemble and/or sensor(s) therein may be of at most about 1500 microwatts (W), 1000 W, 800 W, 500 W, or 250 W. The low power required by the ensemble and/or sensor(s) therein may be between any of the abovementioned power values (e.g., from about 1500 W to about 250 W, from about 1500 W to about 500 W, or from about 500 W to about 250 W). 
     In some embodiments, the testing station includes a barrier. The barrier may selectively allow an individual to pass therethrough. The barrier may comprise one or more doors that (i) hinder an occupant from walking therethrough (e.g., block passage of the occupant) when the door(s) are closed or (ii) allow the occupant to walk past the door(s) when they are open. The doors may comprise a transparent material or a non-transparent material. The door may comprise glass, polymeric, or metallic material. The door may swivel about a hinge. The door may slide, e.g., on bearings. The door may be a rolling door, e.g., about an axle. The door may be operatively coupled (e.g., connected) to one or more posts. The door may be operatively coupled (e.g., connected) to a separator. The separator may facilitate separation of occupants. The separator may comprise a cavity. The cavity may comprise one or more circuitry. The door may automatically and/or reversibly open and close. Closure and opening of the door may be controller by one or more controllers (e.g., as disclosed herein). The door may be operatively coupled to an actuator configured to facilitate opening and/or closing the door, e.g., upon signal received from the controller(s). The actuator may be operatively coupled to the controller(s), e.g., via a network. The separator may or may not comprise at least one controller configured to control the opening and/or closing of the door. The separator may comprise the actuator. The barrier apparatus may include a security gate, a bar, a stile such as a turnstile (e.g., tripod turnstile), and/or a swing gate. The turnstiles may be instead or in addition to the door. The bar and/or stile may comprise any material disclosed herein (e.g., door material) The barrier may comprise an access control barrier. The door may be a fraction of an average individual height. The fraction may be at least about 0.25, 0.3, 0.4, 0.5, 0.75, 1, 1.25, or 1.5 times a height of an average individual. 
       FIG.  3 A  shows an example of a door  310  coupled to a separator  311 , and a door  312  coupled to a separator  316  by a hinge  313 . Separator  316  comprises compartments  314  and  315  that may comprise apparatus(es) for validating and/or interacting with an individual. The cavities may comprise one or more sensors, e.g., that senses one or more characteristic of the environment and/or of the individual, e.g., while passing along the compartment and/or standing next to it. For example, the sensor may sense passing of the individual, and/or the identity of the individual. The compartments may comprise signaling emitters such as sound and/or light. The signaling may indicate if the individual is allowed to pass through the doors, or if the door mechanism malfunctions. For example, a red light may signal lack of authorization to enter, a green light may signal authorization to enter, and an orange light may signal malfunction. The sound may comprise a mechanical (e.g., buzzing sound), or a recording sound (e.g., human voice). The sound may contain a decipherable message (e.g., a sentence). The separator may be stationary. The separator may comprise a non-corrugated surface (e.g., a smooth surface) such as surface  317 . The separator may comprise a rough and/or corrugated surface such as  318 . The separator may comprise one or more slits and/or holes. The separator may comprise on or more lightings (e.g., disposed in the compartment). The slit and/or hole may facilitate transmission of environmental characteristic from the ambient environment to the sensor(s) disposed in the separator and/or emissions (e.g., sound and/or light) to travel from the separator interior into the ambient environment. 
     In some embodiments, the testing station includes one or more frames. The frames may hold an object. The frames and/or framed object may be modular. For example, the relative location of the frames and/or framed object may be altered. The framed object may comprise a window (e.g., tintable window), a board, and/or a display construct.

The Organic LED array may be at least partially transparent (T-OLED). Examples of display construct, their operation and control can be found in U.S. Provisional Patent Application Ser. No. 62/975,706, filed on Feb. 12, 2020, titled “TANDEM VISION WINDOW AND MEDIA DISPLAY,” that is incorporated herein by reference in its entirety. The display construct may be disposed in the frame as a stand-alone framed object. The display construct may be disposed on a window (e.g., a tintable window). The framed object may comprise one or more dispensing and/or sanitation related apparatuses. The dispensing apparatuses may be configured to dispense a glove, a mask, a sanitation liquid, a badge, paper (e.g., tissue). The dispensing apparatus may be a printer (e.g., dispensing printed stickers or papers). The frame may comprise wiring. The frame may comprise one or more devices including a sensor, an emitter, an antenna, a controller, a circuitry, and/or a power source. The testing station may be operatively (e.g., communicatively) coupled to the network (e.g., and to one or more controllers). The display construct (e.g., OLED display) may display messages to an individual seeking to enter the facility. The display construct may display an image of a receptionist. The receptionist may be stationed in the facility or outside of the facility. The receptionist image may be of a live receptionist (e.g., interacting with the individual via video conferencing). The receptionist image may be of an animation. The testing station may comprise a signaling image. The signaling image may be stationary or non-stationary. The signaling image may be changing or non-changing over time. The signaling image may be permanent, or non-permanent (e.g., ephemeral). The signaling image may be transparent or non-transparent. The signaling image may be affixed (e.g., to a fixture of the enclosure such as a floor), or non-affixed. For example, the signaling image may comprise a sticker. The signaling image comprise a painting. The signaling image may comprise carving, embossing, or embroidery. The signaling image may be part of a fabric, e.g., a carpet. The signaling image may be a projection of light. The projection of flight may be changing or non-changing over time. The testing framing may comprise a projector projecting lighting on the individual and/or on the floor to form the signaling image. The projected lighting may signal an individual where to stand (e.g., a circle may be projected signaling the individual to stand in the circle). The projected lighting may signal an individual in what direction to stand (e.g., the projected lighting may comprise footprints of a stationary individual disposed in a direction, signaling the individual to stand in the direction). The projected lighting may signal an individual in what direction to walk (e.g., the projected lighting may comprise footprints of a walking individual disposed in a direction, signaling the individual to walk in the direction). The projection may be in a color. The projection may be a white projection. The color may signal if the individual is ready to proceed to the next stage in the admission process (e.g., a green color indicating that the individual is free to enter the facility). The color may signal if the individual is not ready to proceed to the next stage in the admission process (e.g., a red color indicating that the individual is unable to enter the facility). The color may signal an error or malfunction (e.g., an orange or yellow color indicating that there is an error in the process and/or in one of the components of the testing station).

At least two of the components may be different. The two components may be disposed (e.g., substantially) parallel to each other. The two components may be disposed at an angle from each other. For example, the two components may form an angle with each other, which angle may be at least about 30 degrees (°), 60°, 90°, 120°, or 180°. The angle may have any value between the aforementioned values. 
     In some embodiments, the testing station is disposed in an enclosure comprising a secondary (e.g., manual and/or more rigorous) testing station.  FIG.  6 A  shows an example of a testing station  612  comprising barrier apparatuses disposed at an entry pass way into a facility  600 , which testing station  612  is disposed in a walkway of an individual that enters the facility through external doors  611 , internal doors  614 , reception area  615 , and into the facility  616 . The barrier apparatuses of  612  are disposed parallel to each other. When an individual is unable to pass the barrier apparatus  612  (e.g., since the individual fails the test), the individual is directed  613  to a secondary testing station  610 . A nurse and/or security officer (present in person, present in image form through a display construct, or virtual through a display construct), interview and/or test the individual more rigorously as compared to the examination in testing station  612 .  FIG.  6 B  shows an example of a testing station  622  comprising parallel barrier apparatuses and framing apparatuses disposed at an entry pass way into a facility  630 , which testing station  622  is disposed in a walkway of an individual that enters the facility through external doors  621  in a direction  631 , which individual enters through internal doors  624 , reception area  625 , and into the facility  626 . The barrier apparatuses of  622  are disposed parallel to each other. The framing apparatuses of  622  are disposed parallel to each other. The barrier apparatuses of  622  are disposed parallel to the framing apparatuses. Every framing apparatus of testing station  622  is disposed adjacent (e.g., contacting or not contacting) to at least one barrier apparatus. Every barrier apparatus of testing station  622  is disposed adjacent (e.g., contacting or not contacting) to at least one framing apparatus. A framing apparatus of the testing station  622  forms a pair with one barrier apparatus. When an individual is unable to pass the barrier apparatus  622  (e.g., since the individual fails the test), the individual is directed  623  to a secondary testing station  620 . 
     In some embodiments, a framing apparatus forms a pair with a barrier apparatus. The framing apparatus and/or barrier apparatus may be coupled to a network (e.g., via wired and/or wireless communication). The framing apparatus and barrier apparatus may or may not be directly operatively (e.g., communicatively) coupled to each other. The framing apparatus and barrier apparatus may be operatively (e.g., communicatively) coupled to each other via the network. The framing apparatus and/or barrier apparatus may comprise at least one controller (e.g., disposed therein or thereon). The framing apparatus and barrier apparatus may be operatively (e.g., communicatively) coupled to at least one controller (e.g., via the network). 
     In some embodiments, an individual entering the facility undergoes one or more reception procedures (e.g., operations). The reception operations may relate to entry to an admission process, equipment dispensing, bodily characteristics (e.g., sanitation), barrier, and/or to a secondary check. If the individual is a non-employee, then the operations involve a host escorting the individual into the facility and/or signature of an agreement (e.g., non-disclosure agreement). The operations may be at any order. 
       FIG.  7    shows a flowchart depicting the various operation relate to personnel (e.g., an employee) undergoing admission process  710 , equipment dispensing  720 , bodily characteristics  730 , barrier  740 , and a secondary check  750 . Optional operations are depicted in dotted lines in  FIG.  7   . In the admission operation  710 , the employee can optionally scan  711  the badge allowing him to enter the facility. The testing system assesses in  712  whether the employee is permitted into the facility. If the employee is not allowed to enter, then the employee is optionally directed to leave the facility and/or call a manager in operation  713 . For example, the testing system can analyze whether the employee is pre-authorized to enter (e.g., the employee is in the employee roster, and no special direction to restrict the employee from entry is on file). If the employee is authorized to enter, the doors open in operation  715  and the employee either enters the facility directly in  716  or is directed to the equipment dispensing operation  720 . The testing system then analyzes whether the employee has a tag in operation  721  (e.g., by scanning and/or sensing an identification of the employee using the tag). If the employee does not have a tag, the testing system can dispense and/or allow the employee a new tag in operation  722 , which new tag is assigned to the employee. In operation  723 , the testing system analyses whether the employee complies with equipment related safety protocols of the jurisdiction in which the facility is disposed and/or safety protocol of the facility (e.g., wearing protective gear such as a mask, lab coat, steal toed shoes, and/or safety goggles). If the employee does not comply, the testing system may dispense the required equipment in  724  or block the employee from entry until the employee appears with the safety compliance (blocking operation not shown). The testing system may ascertain that the employee has taken the equipment in optional operation  725 . The employee will then undergo an operation  730  related to bodily characteristics (e.g., temperature or cough) in which the employee optionally (e.g., within jurisdictional and/or facility protocol) sanitizes any required body parts (e.g., hands) in operation  731 , one or more bodily characteristics are sensed in operation  732  (e.g., using one or more sensors), the testing system then analyzes whether the bodily characteristic(s) are normal or abnormal (e.g., using threshold(s) and/or characteristic signature). If the bodily characteristic(s) of the employee are normal, then the testing system unlocks the barrier in operation  741  of the barrier operational stage  740 , and the employee enters the facility in operation  742 . Results of the analysis of the bodily characteristic(s) can be optionally sent to the employee and/or facility in operation  736 . If the bodily characteristic(s) are found to be abnormal in  733 , then the employee is notified in  734  and the facility is notified in  735 . The employee is then informed of various options in operation  751 . The employee should chooses in operation  752  (e.g., by entering the information into the system) if the employee wishes to continue with the admission process. If the employee wishes to continue, the employee is directed to proceed to a secondary check in operation  753  (e.g., a manual and/or more rigorous examination of the employee). If the employee does not wish to continue the admission process, the employee is sent away in operation  752 . The results of the employee decision are sent to the facility and/or recorded. 
       FIG.  8    shows a flowchart depicting various operation relate to personnel (e.g., a visitor, e.g., non-employee) undergoing admission process  810 , agent and bodily characteristics  820 , equipment dispensing  830 , barrier  840 , and entry into the facility  850 . Optional operations are depicted in dotted lines in  FIG.  8   . In the admission operation  810 , the testing system tries to detect an employee badge (e.g., tag). If the employee tag is detected, then the operations in  FIG.  7    take place. If the tag is not detected (and the individual is not in the employee roster), then the testing system classifies the individual as a visitor. The testing system verifies if the visitor is allowed access into the facility in operation  812  checking if the visitor is expected. For example, the testing system can analyze whether the visitor is pre-authorized to enter (e.g., the visitor is in the visitor roster, and no special direction to restrict the visitor from entry is on file). If the visitor is not allowed to enter the facility, then the visitor is optionally directed to leave the facility and/or call a host in operation  813 . If the visitor is authorized to enter, the visitor host is called in  815 , and once the host arrives in  816 , the doors and the visitor either enters the facility directly in  821  or is directed to the equipment dispensing operation  820 . The testing system then senses (e.g., using sensor(s)) whether the bodily characteristic(s) of the visitor are within normal range or are abnormal in operation  823 . If the bodily characteristic(s) are normal, then the host is notified in operation  825  and the employee is requested to leave the facility in operation  855 . If the bodily characteristic(s) are not abnormal (e.g., are within normal range), then the results are notified (e.g., transmitted) to the facility and/or host in operation  826 , and the visitor continues to the equipment and sanitation operation stage. In operation  831 , the testing system analyses whether the visitor complies with equipment related safety protocols (e.g., standards) of the jurisdiction in which the facility is disposed and/or safety protocol of the facility (e.g., wearing protective gear such as a mask, lab coat, steal toed shoes, and/or safety goggles). If the employee does not comply, the testing system may dispense the required equipment in  832  or block the employee from entry until the employee appears with the safety compliance (blocking operation not shown). The system may ascertain that the employee has taken the equipment in optional operation  833 . The employee may optionally be requested to sanitize body part(s) (e.g., hands) in operation  834 . If the visitor is complies with equipment related safety protocols (e.g., standards), then the visitor may optionally be requested to sanitize body part(s) (e.g., hands) in operation  834 . The testing system may or may not verify sanitation (e.g., using sensor(s)). Once the visitor complies with the equipment and sanitation operation stage  830 , the visitor starts operation  840  relating to an agreement. The visitor is directed to wait for the host (e.g., if the host was did not arrive) in operation  841 , and the visitor is requested to sign an agreement (e.g., non-disclosure agreement) in operation  842 . If the visitor signs the agreement, a badge (e.g., tag) may be provided to the visitor in operation  843 . If the visitor does not sign the agreement, then the host is accountable to the visitor in  844  (e.g., may ask the visitor to leave in operation  855 ). Once the visitor signs the agreement, the testing system unlocks the barrier in operation  851  of the exit/entrance operational stage  850 , and the employee enters the facility in operation  852 . Results of the analysis of the bodily characteristic(s) can be optionally sent to the visitor and/or facility. If the bodily characteristic(s) of the visitor are found to be abnormal, then the visitor may be notified (e.g., using a message such as through email, phone, text, sound, image, or print). The visitor may be informed of various options. The visitor should chooses (e.g., by entering the information into the system) if the visitor wishes to continue with the admission process. If the visitor wishes to continue, the visitor is directed to proceed to a secondary check (e.g., a manual and/or more rigorous examination of the employee). If the visitor does not wish to continue the admission process, the visitor is sent away from the facility. The results of the visitor decision may be sent to the facility and/or recorded. 
     In some embodiments, the testing system is operatively coupled to one or more controllers. The controllers are configured to control one or more devices of the facility. The analysis of the testing system may be carried out at least in part by the one or more controllers that control the facility (e.g., that may comprise or may operatively couple to a building management system). 
     In some embodiments, one or more sensors are attached to a mobile traveler. The traveler can be animate or inanimate. For example, the senor(s) can be carried by a person, that walks about a facility. For example, the sensor(s) can be carried by a transitory robot (e.g., self-propelled vehicle). For example, an airborne vehicle (e.g., a drone) or a ground transported vehicle (e.g., a wheeled vehicle). A location of the traveler may be known. The traveler and/or tested individual may identify its location. The location of the traveler and/or tested individual may be identified at least in part via electromagnetic radiation related technology, for example, via satellite (e.g., GPS), Bluetooth, UHF and/or UWB technology. The location of the traveler may be identified at least in part via at least one sensor in the facility (e.g., a radar, a moment sensor, an antenna, and/or an optical sensor (e.g., a camera such as a video camera)). The location of the traveler and/or tested individual may be identified at least in part via the mobile device (e.g., cellular phone) that the individual and/or traveler is carrying. 
     In some embodiments, an environmental property excreted and/or influenced by an individual has a propagation pattern in the environment. The propagation pattern may have a distinct and/or identified pattern, e.g., that can be measured by one or more sensors. For example, a heat emitted by an individual has a diffusion pattern in an environment atmosphere. For example, a carbon dioxide emission by an individual, has an emission pattern in an environment. For example, the carbon dioxide can be more pronounced around the mouth and the nose of the individual, e.g., and the expulsion rate, direction, pressure, and/or speed can be measured. In the example shown in  FIG.  12   , shows a contour map example of a horizontal (e.g., top) view of an office environment depicting various levels of CO 2  concentrations. Based on the expulsion of CO, and its concentration variation in the room, positions of nine individuals  1201 - 1209  can be identified. Moreover, the individuals  1201 - 1204  can be identified as facing individuals  1205 - 1208 , and individual  1209  can be identified as positioned between the group of individuals  1201 - 1204  and the group of individuals  1205 - 1208 , and normal thereto. Additionally, by considering the contour map, one can postulate that a wind is blowing in the direction from individuals  1201 - 1204  towards individuals  1205 - 1208 , with the wind having an uneven affect in the room. The wind appears to have greater affect in the direction from individuals  1201  and  1205  towards individual  1209 . The wind is least affecting individuals  1201  and  1205 , more affecting individuals  1202  and  1206 , even more affecting individuals  1203  and  1207 , even more affecting individuals  1204  and  1208 , and mostly affecting individual  1209 . The wind could enter through an opening such as a vent, an open window, or an open door. Thus, a sensed environmental property in the room can be utilized (at least in party) to locate individual(s) in an enclosure. 
     The enclosure may have an ambient pressure and/or temperature. The enclosure may have a pressure different from an ambient pressure (e.g., lower and/or higher than the ambient pressure). The enclosure may have a temperature different from an ambient temperature (e.g., lower and/or higher than the ambient temperature). The enclosure be a specialized enclosure (e.g., configured to hold the pressure and/or temperature different from ambient temperature). The ambient pressure may be one atmosphere. The ambient temperature may be about 25° C. The ambient pressure and atmosphere may be standard pressure and atmosphere. 
     In some examples, data from a plurality of sensors (e.g., of the same type or of different types) can be utilized to assess the environment and individual(s) effect on the environment. Such assessment may shed light on the wellbeing of the individual (e.g., having normal or abnormal bodily characteristics). For example, temperature, humidity, and/or carbon dioxide patterns in an environment may be utilized to locate and/or assess the wellbeing of individual(s). data from the plurality of (e.g., different type of) sensors can be correlated (e.g., cross correlated). 
     In some embodiments, owners and/or users of the data may take actions if the individual exhibits one or more abnormal characteristics. For example, they may initiate medical treatment of the individual, quarantine the individual, and/or take steps to remove the individual (e.g., to reduce risk of harming others). In some embodiments, the control system of the facility may initiate an action. For example, the control system may after, or direct alteration of, the status of one or more devices operatively coupled to a building management system. For example, the control system may after, or direct alteration of, the status of an HVAC system, a lightening system, or a buzzer. For example, lighting may flash, buzzer will buzz, or ventilation will increase, in response to the result. 
     In some embodiments, an enclosure includes one or more sensors. The sensor may facilitate controlling the environment of the enclosure such that occupants of the enclosure may have an environment that is more comfortable, delightful, beautiful, healthy, productive (e.g., in terms of occupant performance), easer to live (e.g., work) in, or any combination thereof. The sensor(s) may be configured as low or high resolution sensors. Sensor may provide on/off indications of the occurrence and/or presence of a particular environmental event (e.g., one pixel sensors). In some embodiments, the accuracy and/or resolution of a sensor may be improved via artificial intelligence analysis of its measurements. Examples of artificial intelligence techniques that may be used include: reactive, limited memory, theory of mind, and/or self-aware techniques know to those skilled in the art). Sensors may be configured to process, measure, analyze, detect and/or react to one or more of: data, temperature, humidity, sound, force, pressure, electromagnetic waves, position, distance, movement, flow, acceleration, speed, vibration, dust, light, glare, color, gas(es), and/or other aspects (e.g., characteristics) of an environment (e.g., of an enclosure). The gases may include volatile organic compounds (VOCs). The gases may include carbon monoxide, carbon dioxide, water vapor (e.g., humidity), oxygen, radon, and/or hydrogen sulfide. 
     In some embodiments, processing sensor data comprises performing sensor data analysis. The sensor data analysis may comprise at least one rational decision making process, and/or learning. The sensor data analysis may be utilized to adjust and environment, e.g., by adjusting one or more components that affect the environment of the enclosure. The data analysis may be performed by a machine based system (e.g., a circuitry). The circuitry may be of a processor. The sensor data analysis may utilize artificial intelligence. The sensor data analysis may rely on one or more models (e.g., mathematical models). In some embodiments, the sensor data analysis comprises linear regression, least squares fit, Gaussian process regression, kernel regression, nonparametric multiplicative regression (NPMR), regression trees, local regression, semiparametric regression, isotonic regression, multivariate adaptive regression splines (MARS), logistic regression, robust regression, polynomial regression, stepwise regression, ridge regression, lasso regression, elasticnet regression, principal component analysis (PCA), singular value decomposition, fuzzy measure theory, Borel measure, Han measure, risk-neutral measure, Lebesgue measure, group method of data handling (GMDH), Naive Bayes classifiers, k-nearest neighbors algorithm (k-NN), support vector machines (SVMs), neural networks, support vector machines, classification and regression trees (CART), random forest, gradient boosting, or generalized linear model (GLM) technique.  FIG.  9    shows an example of a diagram  900  of an arrangement of sensors distributed among enclosures. In the example shown in  FIG.  9   , controller  905  is communicatively linked  908  with sensors located in enclosure A (sensors  910 A,  910 B,  910 C, . . .  910 Z), enclosure B (sensors  915 A,  915 B,  915 C,  915 Z), enclosure C (sensors  920 A,  920 B,  920 C, . . .  920 Z), and enclosure Z (sensors  985 A,  985 B,  985 C, . . .  985 Z). Communicatively linked comprises wired and/or wireless communication. In some embodiments, a sensor ensemble includes at least two sensors of a differing types. In some embodiments, a sensor ensemble includes at least two sensors of the same type. In the example shown in  FIG.  9   , sensors  910 A,  910 B,  910 C, . . .  910 Z of enclosure A represent an ensemble. An ensemble of sensors can refer to a collection of diverse sensors. In some embodiments, at least two of the sensors in the ensemble cooperate to determine environmental parameters, e.g., of an enclosure in which they are disposed. For example, a sensor ensemble may include a carbon dioxide sensor, a carbon monoxide sensor, a volatile organic chemical sensor, an ambient noise sensor, a visible light sensor, a temperature sensor, and/or a humidity sensor. A sensor ensemble may comprise other types of sensors, and claimed subject matter is not limited in this respect. The enclosure may comprise one or more sensors that are not part of an ensemble of sensors. The enclosure may comprise a plurality of ensembles. At least two of the plurality of ensembles may differ in at least one of their sensors. At least two of the plurality of ensembles may have at least one of their sensors that is similar (e.g., of the same type). For example, an ensemble can have two motion sensors and one temperature sensor. For example, an ensemble can have a carbon dioxide sensor and an IR sensor. The ensemble may include one or more devices that are not sensors. The one or more other devices that are not sensors may include sound emitter (e.g., buzzer), and/or electromagnetic radiation emitters (e.g., light emitting diode). In some embodiments, a single sensor (e.g., not in an ensemble) may be disposed adjacent (e.g., immediately adjacent such as contacting) another device that is not a sensor. The controller may be communicatively coupled to the sensor ensemble or may be a part of the sensor ensemble. 
     Sensors of a sensor ensemble may collaborate with one another. A sensor of one type may have a correlation with at least one other type of sensor. A situation in an enclosure may affect one or more of different sensors. Sensor readings of the one or more different may be correlated and/or affected by the situation. The correlations may be predetermined. The correlations may be determined over a period of time (e.g., using a learning process). The period of time may be predetermined. The period of time may have a cutoff value. The cutoff value may consider an error threshold (e.g., percentage value) between a predictive sensor data and a measured sensor data, e.g., in similar situation(s). The time may be ongoing. The correlation may be derived from a learning set (also referred to herein as “training set”). The learning set may comprise, and/or may be derived from, real time observations in the enclosure. The observations may include data collection (e.g., from sensor(s)). The learning set may comprise sensor(s) data from a similar enclosure. The learning set may comprise third party data set (e.g., of sensor(s) data). The learning set may derive from simulation, e.g., of one or more environmental conditions affecting the enclosure. The learning set may compose detected (e.g., historic) signal data to which one or more types of noise were added. The correlation may utilize historic data, third party data, and/or real time (e.g., sensor) data. The correlation between two sensor types may be assigned a value. The value may be a relative value (e.g., strong correlation, medium correlation, or weak correlation). The learning set that is not derived from real-time measurements, may serve as a benchmark (e.g., baseline) to initiate operations of the sensors and/or various components that affect the environment (e.g., HVAC system, and/or tinting windows). Real time sensor data may supplement the learning set, e.g., on an ongoing basis or for a defined time period. The (e.g., supplemented) learning set may increase in size during deployment of the sensors in the environment. The initial learning set may increase in size, e.g., with inclusion of additional (i) real time measurements, (ii) sensor data from other (e.g., similar) enclosures, (iii) third party data, (iv) other and/or updated simulation. 
     In some embodiments, data from sensors may be correlated. Once a correlation between two or more sensor types is established, a deviation from the correlation (e.g., from the correlation value) may indicate an irregular situation and/or malfunction of a sensor of the correlating sensors. The malfunction may include a slippage of a calibration. The malfunction may indicate a requirement for re-calibration of the sensor. A malfunction may comprise complete failure of the sensor. In an example, a movement sensor may collaborate with a carbon dioxide sensor. In an example, responsive to a movement sensor detecting movement of one or more individuals in an enclosure, a carbon dioxide sensor may be activated to begin taking carbon dioxide measurements. An increase in movement in an enclosure, may be correlated with increased levels of carbon dioxide. In another example, a motion sensor detecting individuals in an enclosure may be correlated with an increase in noise detected by a noise sensor in the enclosure. In some embodiments, detection by a first type of sensor that is not accompanied by detection by a second type of sensor may result in a sensor posting an error message. For example, if a motion sensor detects numerous individuals in an enclosure, without an increase in carbon dioxide and/or noise, the carbon dioxide sensor and/or the noise sensor may be identified as having failed or as having an erroneous output. An error message may be posted. A first plurality of different correlating sensors in a first ensemble may include one sensor of a first type, and a second plurality of sensors of different types. If the second plurality of sensors indicate a correlation, and the one sensor indicates a reading different from the correlation, there is an increased likelihood that the one sensor malfunctions. If the first plurality of sensors in the first ensemble detect a first correlation, and a third plurality of correlating sensors in a second ensemble detect a second correlation different from the first correlation, there is an increased likelihood that the situation to which the first ensemble of sensors is exposed to is different from the situation to which the third ensemble of sensors are exposed to. 
     Sensors of a sensor ensemble may collaborate with one another. The collaboration may comprise considering sensor data of another sensor (e.g., of a different type) in the ensemble. The collaboration may comprise trends projected by the other sensor (e.g., type) in the ensemble. The collaboration may comprise trends projected by data relating to another sensor (e.g., type) in the ensemble. The other sensor data can be derived from the other sensor in the ensemble, from sensors of the same type in other ensembles, or from data of the type collected by the other sensor in the ensemble, which data does not derive from the other sensor. For example, a first ensemble may include a pressure sensor and a temperature sensor. The collaboration between the pressure sensor and the temperature sensor may comprise considering pressure sensor data while analyzing and/or projecting temperature data of the temperature sensor in the first ensemble. The pressure data may be (i) of a pressure sensor in the first ensemble, (ii) of pressure sensor(s) in one or more other ensembles, (iii) pressure data of other sensor(s) and/or (iv) pressure data of a third party. 
     In some embodiments, sensor ensembles, are distributed throughout an enclosure. Sensors of a same type may be dispersed in an enclosure, e.g., to allow measurement of environmental parameters at various locations of an enclosure. Sensors of the same type may measure a gradient along one or more dimensions of an enclosure. A gradient may include a temperature gradient, an ambient noise gradient, or any other variation (e.g., increase or decrease) in a measured parameter as a function of location from a point. A gradient may be utilized in determining that a sensor is providing erroneous measurement (e.g., the sensor has a failure).  FIG.  10    shows an example of a diagram  1090  of an arrangement of sensor ensembles in an enclosure. In the example of  FIG.  10   , ensemble  1092 A is positioned at a distance D 1  from vent  1096 . Sensor ensemble  1092 B is positioned at a distance D 2  from vent  1096 . Sensor ensemble  1092 C is positioned at a distance Da from vent  1096 . In the example of  FIG.  10   , vent  1096  corresponds to an air conditioning vent, which represents a relatively constant source of cooling air and a relatively constant source of white noise. Thus, in the example of  FIG.  10   , temperature and noise measurements are made by sensor ensemble  1092 A. Temperature and noise measurements made by sensor  1092 A are shown by output reading profile  1094 A. Output reading profile  1094 A indicates a relatively low temperature and a significant amount of noise. Temperature and noise measurements made by sensor ensemble  1092 B are shown by output reading profile  1094 B. Output reading profile  1094 B indicates a somewhat higher temperature, and a somewhat reduced noise level. Temperature and noise measurements made by sensor ensemble  1092 C are shown by output reading profile  1094 C. Output reading profile  1094 C indicates a temperature somewhat higher than the temperature measured by sensor ensemble  1092 B and  1092 A. Noise measured by sensor ensemble  1092 C indicates a lower level than noise measured by sensor ensemble  1092 A and  1092 B. In an example, if a temperature measured by sensor ensemble  1092 C indicates a lower temperature than a temperature measured by sensor ensemble  1092 A, one or more processors and/or controllers may identify sensor ensemble  1092 C sensor as providing erroneous data. 
     In another example of a temperature gradient, a temperature sensor installed near a window may measure increased temperature fluctuations with respect to temperature fluctuations measured by a temperature sensor installed at a location opposite the window. A sensor installed near a midpoint between the window and the location opposite the window may measure temperature fluctuations in between those measured near a window with respect to those measured at the location opposite the window. In an example, an ambient noise sensor installed near an air conditioning (or near a heating vent) may measure greater ambient noise than an ambient noise sensor installed away from the air conditioning or heating vent. 
     In some embodiments, a sensor of a first type cooperates with a sensor of a second type. In an example, an infrared radiation sensor may cooperate with a temperature sensor. Cooperation among sensor types may comprise establishing a correlation (e.g., negative or positive) among readings from sensors of the same type or of differing types. For example, an infrared radiation sensor measuring an increase in infrared energy may be accompanied by (e.g., positively correlated to) an increase in measured temperature. A decrease in measured infrared radiation may be accompanied by a decrease in measured temperature. In an example, an infrared radiation sensor measuring an increase in infrared energy that is not accompanied by a measurable increase in temperature, may indicate failure or degradation in operation of a temperature sensor. 
     In some embodiments, one or more sensors are included in an enclosure. For example, an enclosure may include at least 1, 2, 4, 5, 8, 10, 20, 50, or 500 sensors. The enclosure may include a number of sensors in a range between any of the aforementioned values (e.g., from about 1 to about 1000, from about 1 to about 500, or from about 500 to about 1000). The sensor may be of any type. For example, the sensor may be configured (e.g., and/or designed) to measure concentration of a gas (e.g., carbon monoxide, carbon dioxide, hydrogen sulfide, volatile organic chemicals, or radon). For example, the sensor may be configured (e.g., and/or designed) to measure ambient noise. For example, the sensor may be configured (e.g., and/or designed) to measure electromagnetic radiation (e.g., RF, microwave, infrared, visible light, and/or ultraviolet radiation). For example, the sensor may be configured (e.g., and/or designed) to measure security-related parameters, such as (e.g., glass) breakage and/or unauthorized presence of personnel in a restricted area. Sensors may cooperate with one or more (e.g., active) devices, such as a radar or lidar. The devices may operate to detect physical size of an enclosure, personnel present in an enclosure, stationary objects in an enclosure and/or moving objects in an enclosure. 
     In some embodiments, the sensor is operatively coupled to at least one controller. The coupling may comprise a communication link. A communications link (e.g.,  FIG.  9 ,  908   ) may comprise any suitable communications media (e.g., wired and/or wireless). The communication link may comprise a wire, such as one or more conductors arranged in a twisted-pair, a coaxial cable, and/or optical fibers. A communications link may comprise a wireless communication link, such as Wi-Fi, Bluetooth, ZigBee, cellular, or optical. One or more segments of the communications link may comprise a conductive (e.g., wired) media, while one or more other segments of a communications link may comprise a wireless link. The communication network may comprise one or more levels of encryption. The communication network may be communicatively coupled to the cloud and/or to one or more servers external to the facility. The communication network may support at least a third generation (3G), fourth generation wireless (4G), or fifth-generation wireless (5G) communication. The communication network may support cellular signals external and/or internal to the facility. The downlink communication network speeds may have a peak data rate of at least about 5 Gigabits per second (Gb/s), 10 Gb/s, or 20 Gb/s. The uplink communication network speeds may have a peak data rate of at least about 2 Gb/s, 5 Gb/s, or 10 Gb/s. 
     In some embodiments, the enclosure is a facility (e.g., building). The enclosure may comprise a wall, a door, or a window. In some embodiments, at least two enclosures of a plurality of enclosures are disposed in the facility. In some embodiments, at least two enclosures of a plurality of enclosures are disposed different facilities. The different facilities may be a campus (e.g. and belong to the same entity). At least two of the plurality of enclosures may reside in the same floor of the facility. At least two of the plurality of enclosures may reside in different floors of the facility. Enclosures of  FIG.  9   , such as enclosures A, B, C, and Z, may correspond to enclosures located on the same floor of a building, or may correspond to enclosures located on different floors of the building. Enclosures of  FIG.  9    may be located in different buildings of a multi-building campus. Enclosures of  FIG.  9    may be located in different campuses of a multi-campus neighborhood. 
     In an example, for gas sensors disposed in a room (e.g., in an office environment), a relevant parameter may correspond to gas (e.g., CO 2 ) levels, where desired levels are typically in a range of about 1000 ppm or less. In an example, a CO 2  sensor may determine that self-calibration should occur during a time window where CO 2  levels are minimal such as when no occupants are in the vicinity of the sensor (e.g. see CO 2  levels before 18000 seconds in  FIG.  11   ). Time windows during which fluctuations in CO 2  levels are minimal, may correspond to, e.g., a one-hour period during lunch from about 12:00 PM to about 1:00, and during closed business hours.  FIG.  12    shows a contour map example of a horizontal (e.g., top) view of an office environment depicting various levels of CO 2  concentrations. The gas (CO 2 ) concentrations may be measured by sensors placed at various locations of the enclosure (e.g., office). 
     Positional and/or stationary characteristics (e.g., placement of walls and/or windows) of the enclosure may be utilized in measuring the characteristics of a give environment. The positional and/or stationary characteristics of the enclosure may be derived independently (e.g., from 3 rd  party data and/or from non-sensor data). The positional and/or stationary characteristics of the enclosure may be derived using data from the one or more sensors disposed in the environment. When the environment is minimally disturbed with respect to the measured environmental characteristic (e.g., when no one is present in an environment, and/or when the environment is quiet), some sensor data may be used to sense and/or identify position of (e.g., stationary and/or non-stationary) objects to determine the environment. Determining the position of objects comprises determining an (e.g., human) occupancy in the environment. Distance and/or location related measurements may utilize sensor(s) such as radar and/o ultrasonic sensors. Distance and location related measurements may derive from sensors that to not traditionally correlated to location and/or distance. Objects disposed in, or that are part of, an enclosure may have distinct sensor signatures. For example, location of people in the enclosure may correlate to distinct temperature, humidity and/or CO 2  signatures. For example, location of a wall may correlate to an abrupt change in the distribution of temperature, humidity and/or CO 2  in the enclosure. For example, location of a window or door (whether open or closed) may correlate to a change in the distribution of temperature, humidity and/or CO 2  next to the window or door. The one or more sensors in the enclosure may monitor any environmental changes and/or correlates such changes to changes in subsequently monitored values. In some cases, lack of fluctuations in monitored values may be used as an indication that a sensor is damaged, and that the sensor may need to be remove or replaced. 
     In some embodiments, a sensor transmits (e.g., beacons) data to a receiver, e.g., a sensor or suite of sensors. The suite of sensors can also be referred to as an “ensemble of sensors.” The sensors in the suite of sensors can be analogous to those deployed in a space of an enclosure. 
     In some embodiments, a plurality of sensors is assembled into a sensor suite (e.g., sensor ensemble). At least two sensors of the plurality of sensors may be of a different type (e.g., are configured to measure different properties). Various sensor types can be assembled together (e.g., bundled up) and form a sensor suite. The plurality of sensors may be coupled to one electronic board. The electrical connection of at least two of the plurality of sensors in the sensor suit may be controlled (e.g., manually and/or automatically). For example, the sensor suite may be operatively coupled to, or comprise, a controller (e.g., a microcontroller). The controller may control and on/off connectivity of the sensor to electrical power. The controller can thus control the time (e.g., period) at which the sensor will be operative. 
     In some embodiments, one or more sensors are added or removed from a community of sensors, e.g., disposed in the enclosure and/or in the sensor suite (e.g., sensor ensemble). Newly added sensors may inform (e.g., beacon) other members of a community of sensor of its presence and relative location within a topology of the community. Examples of sensor community(ies) can be found, for example, in U.S. Provisional Patent Application Ser. No. 62/958,653, filed Jan. 8, 2020, titled “SENSOR AUTOLOCATION,” that is incorporated by reference herein in its entirety. Examples of sensor, and sensor ensembles can be found, for example, U.S. Provisional Patent Application Ser. No. 62/967,204, filed Jan. 29, 2020 titled “SENSOR CALLIBRATION AND OPERATION,” that is incorporated by reference herein in its entirety. These examples include methods of their use, software and apparatuses in which they are utilized and/or included. 
     Sensors of a sensor ensemble may be organized into a sensor module. A sensor ensemble may comprise a circuit board, such as a printed circuit board, in which a number of sensors are adhered or affixed to the circuit board. Sensors can be removed from a sensor module. For example, a sensor may be plugged and/or unplugged from the circuit board. Sensors may be individually activated and/or deactivated (e.g., using a switch). The circuit board may comprise a polymer. The circuit board may be transparent or non-transparent. The circuit board may comprise metal (e.g., elemental metal and/or metal alloy). The circuit board may comprise a conductor. The circuit board may comprise an insulator. The circuit board may comprise any geometric shape (e.g., rectangle or ellipse). The circuit board may be configured (e.g., may be of a shape) to allow the ensemble to be disposed in a mullion (e.g., of a window). The circuit board may be configured (e.g., may be of a shape) to allow the ensemble to be disposed in a frame (e.g., door frame and/or window frame). The mullion and/or frame may comprise one or more holes to allow the sensor(s) to obtain (e.g., accurate) readings. The circuit board may include an electrical connectivity port (e.g., socket). The circuit board may be connected to a power source (e.g., to electricity). The power source may comprise renewable or non-renewable power source. 
       FIG.  13    shows an example of a diagram  1300  of an ensemble of sensors organized into a sensor module. Sensors  1310 A,  1310 B,  1310 C, and  1310 D are shown as included in sensor ensemble  1305 . An ensemble of sensors organized into a sensor module may include at least 1, 2, 4, 5, 8, 10, 20, 50, or 500 sensors. The sensor module may include a number of sensors in a range between any of the aforementioned values (e.g., from about 1 to about 1000, from about 1 to about 500, or from about 500 to about 1000). Sensors of a sensor module may comprise sensors configured or designed for sensing a parameter comprising, temperature, humidity, carbon dioxide, particulate matter (e.g., between 2.5 μm and 10 μm), total volatile organic compounds (e.g., via a change in a voltage potential brought about by surface adsorption of volatile organic compound), ambient light, audio noise level, pressure (e.g. gas, and/or liquid), acceleration, time, radar, lidar, radio signals (e.g., ultra-wideband radio signals), passive infrared, glass breakage, or movement detectors. The sensor ensemble (e.g.,  1305 ) may comprise non-sensor devices, such as buzzers and light emitting diodes. Examples of sensor ensembles and their uses can be found in U.S. patent application Ser. No. 16/447,169, filed Jun. 20, 2019, titled “SENSING AND COMMUNICATIONS UNIT FOR OPTICALLY SWITCHABLE WINDOW SYSTEMS,” that is incorporated herein by reference in its entirety. 
     In some embodiments, an increase in the number and/or types of sensors may be used to increase a probability that one or more measured property is accurate and/or that a particular event measured by one or more sensor has occurred. In some embodiments, sensors of sensor ensemble may cooperate with one another. In an example, a radar sensor of sensor ensemble may determine presence of a number of individuals in an enclosure. A processor (e.g., processor  1315 ) may determine that detection of presence of a number of individuals in an enclosure is positively correlated with an increase in carbon dioxide concentration. In an example, the processor-accessible memory may determine that an increase in detected infrared energy is positively correlated with an increase in temperature as detected by a temperature sensor. In some embodiments, network interface (e.g.,  1350 ) may communicate with other sensor ensembles similar to sensor ensemble. The network interface may additionally communicate with a controller. 
     Individual sensors (e.g., sensor  1310 A, sensor  1310 D, etc.) of a sensor ensemble may comprise and/or utilize at least one dedicated processor. A sensor ensemble may utilize a remote processor (e.g.,  1354 ) utilizing a wireless and/or wired communications link. A sensor ensemble may utilize at least one processor (e.g., processor  1352 ), which may represent a cloud-based processor coupled to a sensor ensemble via the cloud (e.g.,  1350 ). Processors (e.g.,  1352  and/or  1354 ) may be located in the same building, in a different building, in a building owned by the same or different entity, a facility owned by the manufacturer of the window/controller/sensor ensemble, or at any other location. In various embodiments, as indicated by the dotted lines of  FIG.  13   , sensor ensemble  1305  is not required to comprise a separate processor and network interface. The sensor ensemble can be an architectural element. These entities may be separate entities and may be operatively coupled to ensemble  305 . The dotted lines in  FIG.  13    designate optional features. In some embodiments, onboard processing and/or memory of one or more ensemble of sensors may be used to support other functions (e.g., via allocation of ensembles(s) memory and/or processing power to the network infrastructure of a building). 
     In some embodiments, a plurality of sensors of the same type may be distributed in an enclosure. At least one of the plurality of sensors of the same type, may be part of an ensemble. For example, at least two of the plurality of sensors of the same type, may be part of at least two ensembles. The sensor ensembles may be distributed in an enclosure. An enclosure may comprise a conference room. For example, a plurality of sensors of the same type may measure an environmental parameter in the conference room. Responsive to measurement of the environmental parameter of an enclosure, a parameter topology of the enclosure may be generated. A parameter topology may be generated utilizing output signals from any type of sensor of sensor ensemble, e.g., as disclosed herein. Parameter topologies may be generated for any enclosure of a facility such as conference rooms, hallways, bathrooms, cafeterias, garages, auditoriums, utility rooms, storage facilities, equipment rooms, and/or elevators. 
       FIG.  14    shows an example of a diagram  1400  of an arrangement of sensor ensembles distributed within an enclosure. In the example shown in  FIG.  14   , a group  1410  of individuals are seated in conference room  1402 . The conference room includes an “X” dimension to indicate length, a “Y” dimension to indicate height, and a “Z” dimension to indicate depth. XYZ being directions a Cartesian coordination system. Sensor ensembles  1405 A,  1405 B, and  1405 C comprise sensors can operate similar to sensors described in reference to sensor ensemble  1305  of  FIG.  13   . At least two sensor ensembles (e.g.,  1405 A,  1405 B, and  1405 C) may be integrated into a single sensor module. Sensor ensembles  1405 A,  1405 B, and  1405 C can include a carbon dioxide (CO 2 ) sensor, an ambient noise sensor, or any other sensor disclosed herein. In the example shown in  FIG.  14   , a first sensor ensemble  1405 A is disposed (e.g., installed) near point  1415 A, which may correspond to a location in a ceiling, wall, or other location to a side of a table at which the group  1410  of individuals are seated. In the example shown in  FIG.  14   , a second sensor ensemble  1405 B is disposed (e.g., installed) near point  1415 B, which may correspond to a location in a ceiling, wall, or other location above (e.g., directly above) a table at which the group  1410  of individuals are seated. In the example shown in  FIG.  14   , a third sensor ensemble  1405 C may be disposed (e.g., installed) at or near point  1415 C, which may correspond to a location in a ceiling, wall, or other location to a side of the table at which the relatively small group  1410  of individuals are seated. Any number of additional sensors and/or sensor modules may be positioned at other locations of conference room  1402 . The sensor ensembles may be disposed anywhere in the enclosure. The location of an ensemble of sensors in an enclosure may have coordinates (e.g., in a Cartesian coordinate system). At least one coordinate (e.g., of x, y, and z) may differ between two or more sensor ensembles, e.g., that are disposed in the enclosure. At least two coordinates (e.g., of x, y, and z) may differ between two or more sensor ensembles, e.g., that are disposed in the enclosure. All the coordinates (e.g., of x, y, and z) may differ between two or more sensor ensembles, e.g., that are disposed in the enclosure. For example, two sensor ensembles may have the same x coordinate, and different y and z coordinates. For example, two sensor ensembles may have the same x and y coordinates, and a different z coordinate. For example, two sensor ensembles may have different x, y, and z coordinates. 
     In particular embodiments, one or more sensors of the sensor ensemble provide readings. In some embodiments, the sensor is configured to sense and/or identify a parameter. The parameter may comprise temperature, particulate matter, volatile organic compounds, electromagnetic energy, pressure, acceleration, time, radar, lidar, glass breakage, movement, or gas. The gas may comprise a Nobel gas. The gas may be a gas harmful to an average human. The gas may be a gas present in the ambient atmosphere (e.g., oxygen, carbon dioxide, ozone, chlorinated carbon compounds, or nitrogen). The gas may comprise radon, carbon monoxide, hydrogen sulfide, hydrogen, oxygen, water (e.g., humidity). The electromagnetic sensor may comprise an infrared, visible light, ultraviolet sensor. The infrared radiation may be passive infrared radiation (e.g., black body radiation). The electromagnetic sensor may sense radio waves. The radio waves may comprise wide band, or ultra-wideband radio signals. The radio waves may comprise pulse radio waves. The radio waves may comprise radio waves utilized in communication. The gas sensor may sense a gas type, flow (e.g., velocity and/or acceleration), pressure, and/or concentration. The readings may have an amplitude range. The readings may have a parameter range. For example, the parameter may be electromagnetic wavelength, and the range may be a range of detected wavelengths. 
     In some embodiments, the sensor data is responsive to the environment in the enclosure and/or to any inducer(s) of a change (e.g., any environmental disruptor) in this environment. The sensors data may be responsive to emitters operatively coupled to (e.g., in) the enclosure (e.g., an occupant, appliances (e.g., heater, cooler, ventilation, and/or vacuum), opening). For example, the sensor data may be responsive to an air conditioning duct, or to an open window. The sensor data may be responsive to an activity taking place in the room. The activity may include human activity, and/or non-human activity. The activity may include electronic activity, gaseous activity, and/or chemical activity. The activity may include a sensual activity (e.g., visual, tactile, olfactory, auditory, and/or gustatory). The activity may include an electronic and/or magnetic activity. The activity may be sensed by a person. The activity may not be sensed by a person. The sensors data may be responsive to the occupants in the enclosure, substance (e.g., gas) flow, substance (e.g., gas) pressure, and/or temperature. 
     In one example, sensor ensembles  1405 A,  1405 B, and  1405 C include carbon dioxide (CO 2 ) sensor, and an ambient noise sensor. A carbon dioxide sensor of sensor ensemble  1405 A may provide a reading as depicted in sensor output reading profile  1425 A. A noise sensor of sensor ensemble  1405 A may provide a reading also depicted in sensor output reading profile  1425 A. A carbon dioxide sensor of sensor ensemble  1405 B may provide a reading as depicted in sensor output reading profile  1425 B. A noise sensor of sensor ensemble  1405 B may provide a reading also as depicted in sensor output reading profile  1425 B. Sensor output reading profile  1425 B may indicate higher levels of carbon dioxide and noise relative to sensor output reading profile  1425 A. Sensor output reading profile  1425 C may indicate lower levels of carbon dioxide and noise relative to sensor output reading profile  1425 B. Sensor output reading profile  1425 C may indicate carbon dioxide and noise levels similar to those of sensor output reading profile  1425 A. Sensor output reading profiles  1425 A,  1425 B, and  1425 C may comprise indications representing other sensor readings, such as temperature, humidity, particulate matter, volatile organic compounds, ambient light, pressure, acceleration, time, radar, lidar, ultra-wideband radio signals, passive infrared, and/or glass breakage, movement detectors. 
     In some embodiments, data from a sensor in a sensor in the enclosure (e.g., and in the sensor ensemble) is collected and/or processed (e.g., analyzed). The data processing can be performed by a processor of the sensor, by a processor of the sensor ensemble, by another sensor, by another ensemble, in the cloud, by a processor of the controller, by a processor in the enclosure, by a processor outside of the enclosure, by a remote processor (e.g., in a different facility), by a manufacturer (e.g., of the sensor, of the window, and/or of the building network). The data of the sensor may have a time indicator (e.g., may be time stamped). The data of the sensor may have a sensor location identification (e.g., be location stamped). The sensor may be identifiably coupled with one or more controllers. 
     In particular embodiments, sensor output reading profiles  1425 A,  1425 B, and  1425 C may be processed. For example, as part of the processing (e.g., analysis), the sensor output reading profiles may be plotted on a graph depicting a sensor reading as a function of a dimension (e.g., the “X” dimension) of an enclosure (e.g., conference room  1402 ). In an example, a carbon dioxide level indicated in sensor output reading profile  1425 A may be indicated as point  1435 A of CO 2  graph  1430  of  FIG.  14   . In an example, a carbon dioxide level of sensor output reading profile  1425 B may be indicated as point  1435 B of CO 2  graph  1430 . In an example, a carbon dioxide level indicated in sensor output reading profile  425 C may be indicated as point  1435 C of CO 2  graph  1430 . In an example, an ambient noise level indicated in sensor output reading profile  1425 A may be indicated as point  1445 A of noise graph  1440 . In an example, an ambient noise level indicated in sensor output reading profile  1425 B may be indicated as point  1445 B of noise graph  1440 . In an example, an ambient noise level indicated in sensor output reading profile  1425 C may be indicated as point  1445 C of noise graph  1440 . 
     In some embodiments, processing data derived from the sensor comprises applying one or more models. The models may comprise mathematical models. The processing may comprise fitting of models (e.g., curve fitting). The model may be multi-dimensional (e.g., two or three dimensional). The model may be represented as a graph (e.g., 2 or 3 dimensional graph). For example, the model may be represented as a contour map (e.g., as depicted in  FIG.  13   ). The modeling may comprise one or more matrices. The model may comprise a topological model. The model may relate to a topology of the sensed parameter in the enclosure. The model may relate to a time variation of the topology of the sensed parameter in the enclosure. The model may be environmental and/or enclosure specific. The model may consider one or more properties of the enclosure (e.g., dimensionalities, openings, and/or environmental disrupters (e.g., emitters)). Processing of the sensor data may utilize historical sensor data, and/or current (e.g., real time) sensor data. The data processing (e.g., utilizing the model) may be used to project an environmental change in the enclosure, and/or recommend actions to alleviate, adjust, or otherwise react to the change. 
     In particular embodiments, sensor ensembles  1405 A,  1405 B, and/or  1405 C, may be capable of accessing a model to permit curve fitting of sensor readings as a function of one or more dimensions of an enclosure. In an example, a model may be accessed to generate sensor profile curves  1450 A,  1450 B,  1450 C,  1450 D, and  1450 E, utilizing points  1435 A,  1435 B, and  1435 C of CO 2  graph  1430 . In an example, a model may be accessed to generate sensor profile curves  1451 A,  1451 B,  1451 C,  1451 B, and  1451 E utilizing points  1445 A,  1445 B, and  1445 C of noise graph  1440 . Additional models may utilize additional readings from sensor ensembles (e.g.,  1405 A,  1405 B, and/or  1405 C) to provide curves in addition to sensor profile curves  1450  and  1451  of  FIG.  14   . Sensor profile curves generated in response to use of a model may sensor output reading profiles indicate a value of a particular environmental parameter as a function of a dimension of an enclosure (e.g., an “X” dimension, a “Y” dimension, and/or a “Z” dimension). 
     In certain embodiments, one or more models utilized to form curves  1450 A- 1450 E and  1451 A- 1451 E) may provide a parameter topology of an enclosure. In an example, a parameter topology (as represented by curves  1450 A- 1450 E and  1451 A- 1451 E) may be synthesized or generated from sensor output reading profiles. The parameter topology may be a topology of any sensed parameter disclosed herein. In an example, a parameter topology for a conference room (e.g., conference room  1402 ) may comprise a carbon dioxide profile having relatively low values at locations away from a conference room table and relatively high values at locations above (e.g., directly above) a conference room table. In an example, a parameter topology for a conference room may comprise a multi-dimensional noise profile having relatively low values at locations away from a conference table and slightly higher values above (e.g., directly above) a conference room table. 
     In some embodiments, sensor data corresponding to an individual is collected upon arrival and an entry station or admittance location to an enclosure (e.g., facility). See for example,  FIGS.  4 A and  4 B  for admittance location examples. In some embodiments, sensor data corresponding to the individual continues to be collected using additional sensors deployed throughout the facility, e.g., as the individual moves in the enclosure and as movement of the individual within the facility is tracked. Thus, abnormal bodily characteristics can be detected with at least one sensor located in a low, regular, and/or high traffic area of a facility at different times and/or with at least one sensor. The individual may be located in various areas of the facility at different times (e.g., times when the individual has moved into another area). The at least one sensor may be a plurality of sensors distributed in the enclosure, and configured to track the bodily characteristic of the individual at the different locations of the enclosure. The sensor data may be obtained from a single sensor having consistency in measurement results that can be compared at different times. In some embodiments, the sensor readings obtained at different times are compared to detect relative changes that may be indicative of a corresponding abnormality affecting the individual (e.g., if they exceed a threshold). 
     In some embodiments, sensor data is collected, compiled, and related to the individual person for whom measurements are obtained. The relation may comprise identification (ID) of the individual. The identification may or may not comprise personal data of the individual (e.g., name, home address, phone number, governmental identification number, fingerprint, retina scan, bodily features, and/or facial features). Sensor data (e.g., comprising raw and/or processed measurements) may be communicated to a database (e.g., via a controller or compiler) along with a respective sensor ID, and a time stamp (e.g., including time, and/or date). The person can be identified with a tag comprising geo-location technology, image processing of a person&#39;s face, size, gait, blood pressure, infrared (IR) signature, heart rate and/or any other personal characteristics (e.g., using radar, IR and the like). The geo-location technology may comprise radio frequency (e.g., RFID) chip. The geo-location technology may comprise BLE, GPS, or UWB technology. The communication can be to at least one software application (e.g., executing in a mobile device of the individual or of another person) and/or to a control system operatively coupled to the enclosure (e.g., building). The application (e.g., control system and/or phone app) may keep a table (for one or more users) of sensor IDs, bodily characteristic (e.g., temperature), and time stamp (e.g., time and date). Data may be collected overtime to determine a “normal” for each uniquely identified individual (e.g., building occupant). The collected data can be used as a baseline for deviation from the norm of that individual. Analysis of the collected data in the database relating to an individual may be performed on the basis of relative sensor data (e.g., for a particular sensor). For example, relative sensor measurements of the person collected at different times may be compared. Since relative measurements are being used, the sensor from which the data is obtained may not need to be calibrated. Absolute values of the sensor data may be immaterial as long as the increments measured by the sensor are accurate (e.g., as long as the relative measurements are accurate). 
     In some embodiments, if a relative difference between sensor measurement exceeds a threshold, an event is triggered (e.g., a notification event). In order to ascertain a relative difference threshold to be used as a trigger that identifies an abnormal condition, a person can be monitored overtime to learn personal bodily characteristic behavior (e.g., oscillations) and behavioral patterns. Monitoring may be performed using a learning module. The learning module may include artificial intelligence (Ai) comprised of machine learning. In one example, an individual occupant and/or user of an enclosure (e.g., wherein the user has a unique identifier such as “123”) may routinely work out at lunch time, and thus their temperature and heartrate may usually increase dramatically during that time period. The Ai may take this into account when considering an adverse variation in characteristics for user # 123 . For example, a temperature, blood pressure, heart rate, etc., of the individual may change according to normal cycles during the course of a day; and these patterns (which may be unique for the individual) may be recorded and norms for the corresponding individual may be established. Seasonal variables and/or other extrinsic factors (referred to herein as “paradigms”) can be input to the ML for improved accuracy. Some such paradigms can be quantified when sensor data is collected. Quantified values can be stored together with the sensor data for use in data analysis, e.g., to determine normal ranges of bodily characteristics of the individual during various paradigms. Once an abnormal condition has been detected for an individual, a report may be generated. Optionally, a notification system may be activated to provide a notification to the affected individual. In some embodiments, notifications are (e.g., also) sent to contactees who may have been exposed to the affected individual. 
       FIG.  15    shows a monitoring system  1500  to monitor one or more characteristic of an individual. To facilitate the identification of individual users within a facility, an individual may possess a trackable devices  1501  such as a cellphone, smartphone, or RFID tag (e.g., incorporated into an identification/access badge). One or more sensors  1502  (e.g., sensor ensembles) may be deployed at a controlled access point and/or arbitrary locations throughout a facility for sensing characteristics of the users at various times. In some embodiments, a trackable device is not needed, provided that individuals can be identified relying only on sensor data (e.g., facial recognition using camera images, or any other unique identifiable characteristic(s) of the individual). 
     A controller system includes modules for ID and location tracking  1503  and a data compiler  1504 . Using sensor data from sensors  1502  and user identifiers from ID tracking module  1503 , data compiler  1504  organizes the sensor data according to individuals (e.g., users), sensor ID, time, and date, to support the analysis of a bodily characteristic of each tracked user over a span of time. The organized data can be stored in a personal database  1505  and/or a collective database  1506 . Personal database  1505  may be stored in a mobile device carried by the user (e.g., a smartphone executing the corresponding app) or other personal device such as a laptop computer. Collective database  1506  may be stored in a networked controller in the facility or external to the facility (e.g., remotely via a cloud). Use of collective database  1506  may be beneficial in connection with tracking multiple users, and optionally performing notifications and contact tracing as described below (e.g.,  FIG.  17   ). 
     For users represented in database  1505  and/or  1506 , the stored sensor data is analyzed according to relative changes of bodily characteristics  1507 . The analysis can use learning module (e.g., artificial intelligence comprising machine learning). Learning module  1507  may be implemented in the networked controller or in the dedicated user device (e.g., smartphone). In some embodiments, when new sensor data for a corresponding user is obtained and entered into database  1505  or  1506 , the analysis module  1507  makes a determination whether sufficient data is stored in order to identify a relevant normal for the sensed characteristic that can be used for a comparison. Seasonal data  1508 , other environmental, and/or other circumstantial factors may be provided to analysis module  1507 , e.g., to improve determinations of the appropriate normal to be applied. A report is provided in  1509  by the analysis module. When the newly collected sensor data indicates an abnormal condition (e.g., a difference between the new sensor data and the calculated norm is greater than a threshold), a notification system  1510  is optionally activated, e.g., to send out various notifications (e.g., a text message or email) to an affected user  1511 , and/or contactees  1512  who may have been in proximity to user  1511  during the abnormal condition (e.g., for a time period above a time-threshold), and/or to a central administrator and/or health official  1513 . 
       FIG.  16    shows a flowchart of a method  1600  for processing sensor data and detecting abnormal bodily characteristics (e.g., conditions). The method of  FIG.  16    may be performed by a centralized controller (e.g., in a network for a facility and/or a cloud-based server) and/or by a dedicated user device. At  1601 , new sensor data is received which may comprise a sensor measurement of a bodily characteristic of an individual (e.g., user), a sensor ID, time and date of the measurement, user ID, and/or (optionally) any paradigm values that may characterize extrinsic factors that may have a predictable influence on the bodily characteristic (e.g., user activity schedules). At  1602 , the incoming data is parsed into the personal and/or collective database, e.g., so that a profile can be built up for each user in which sensor data for the user is aggregated according to shared paradigms, for example. Bodily characteristic analysis is performed/updated at  1603  where respective normals for a user can be established in connection with a sensor ID and/or any relevant paradigms. Establishing normals corresponding to the sensor ID may enable the analysis to rely on relative changes in sensor measurements. In the event that sensors are available which have a calibrated accuracy that allows reliance on absolute magnitudes of sensor measurements, then the parsing of data and the establishment of normals can be performed without regard to sensor ID. At  1604 , an established normal is compared to the new sensor data. If the difference is less than a threshold then there is a return to  1601  in order to continue to receive and process new sensor data. If the difference is greater than the threshold then notification of an abnormal condition is generated at  1605 . An appropriate magnitude for the threshold may depend upon the type of bodily characteristic being monitored and/or upon demographic classifications of a particular user (e.g., sex, age, and/or body type). 
     In some embodiments, tracking of users in a facility provides a basis for identifying potential contactees of users for whom abnormal bodily characteristics are detected. For example, an opt-in building-secure contact tracing system may store times and locations of user movements for correlation. A tracing system may utilize (1) occupancy data for (e.g., anonymized or identifiable) application users, and (2) adequate data infrastructure for retaining the timeframes of their presence. As part of, or separately from, the user tracking and compilation of sensor data for users during their occupancy in a facility (e.g., including at least one building), each user may carry a user device that automatically connects to a network infrastructure upon entering the facility. Based at least in part on interaction with the user device(s), the timeframes of user occupancy can be locally and/or remotely retained (e.g., stored in a tracking database). In some embodiments, tracking of users is based at least in part on communication between the user carried ID device (e.g., smartphone, RFID badge, or laptop) and a wireless and/or wired network infrastructure based at least in part on geo-localization methods such as GPS tracking, ranging, triangulation, WiFi presence, short-range communication such as UWB, and/or other methods. In some embodiments, user tracking is accomplished without a user carried device, e.g., by utilizing remote sensing and identification relying on sensors (e.g., in device ensembles) deployed throughout a facility (e.g. using as facial recognition). 
     In some embodiments, anonymized or non-anonymized tracking statistics are maintained over a rolling time period (e.g., several days, a week, several weeks, months, or years). For each person with a registered user ID, locations and times in the facility may be stored. When a particular user is identified with an abnormal condition, the locations and times of their movements in the building may be retrieved as search criteria for extracting the user IDs and times for other facility occupants which converge with the affected user (e.g., within a distance and optionally for a time above a time-threshold). A push notification to other facility users (e.g., coworkers or cohabitants) on site in a timeframe of potential exposure, may occur in an anonymized or identified fashion. In some embodiments, local retention of potential exposure timeframes serves to facilitate adherence to medical guidelines (e.g., in the jurisdiction) on proper quarantining and/or sanitation procedures, e.g., enabling a targeted response to affected person(s) and/or to those facility areas most frequented by the affected person(s). 
       FIG.  17    shows a tracing system  1700  which can operate on a standalone basis or as part of a bodily characteristic monitoring system embedded in a network in a facility. A presence logging database  1701  includes a plurality of presence logs or buffers for each registered user ID, such as a buffer  1702  for a User X and a buffer  1703  for user Y. Each buffer compiles an array of times and locations for which the respective user was tracked during a rolling time period defined by a specified retention time, coupled with measurements of one or more sensor types. Data that has been stored in a buffer for longer than the retention time can be optionally discarded  1740  as old data (e.g., to mitigate personal security concerns for data that is no longer likely to be needed in connection with contact tracing functions). New tracking data is entered into database  1701  via an interface  1704  which may include resources on the network. The network may be a controller network. Optionally, an anonymizer  1705  may be coupled to interface  1704  which converts tracking data based on actual user IDs into anonymous identifiers for storage in database  1701 . Anonymizer  1705  may be comprised of a high-level security device that prevents user tracking information as stored in database  1701  from revealing user movements if database  1701  is compromised. Anonymizer  1705  is configured to mask user data when it is stored and to unmask data for the limited purpose of sending notifications when the anonymized data is used to identify potential contactees. At  1710  in  FIG.  17   , each person entering a facility presents themselves for authorized access. The time and place of entry are forwarded through interface  1704  (and optionally through anonymizer  1705 ) for storing in a corresponding presence log for that person. During their time at the facility, movements of the person are tracked at  1720 . Tracking may be recorded as times spent within predetermined areas (e.g., zones) of the facility, e.g., in order to reduce data storage requirements and/or processing times. A zone may be a fixed region or may be defined dynamically according to the types of usage and/or changing number of occupants in a space. Continuous tracking data (e.g., by sensors located thorough the facility) may be forwarded through interface  1704  (and optionally through anonymizer  1705 ) for storing in the corresponding presence log. When the person leaves the facility at  1730 , the tracking ceases. 
     In some embodiments, the bodily characteristic tracking sensors may be disposed throughout a facility. There may be a plurality of sensor types required to (e.g., accurately) track one characteristics of an individual throughout the facility. There may be a single sensor type required to (e.g., accurately) track one characteristics of an individual throughout the facility. In some embodiments, the sensor network tracks one bodily characteristic of individual(s) in the facility. In some embodiments, the sensor network tracks a plurality of different bodily characteristics of individual(s) in the facility. The tracking a bodily characteristic of an individual in the facility may comprise recording an identification of an individual, location of the individual in the facility, time and date of the measurement, a type of sensor measurement (e.g., infrared sensor measurements), and optionally another type of sensor measurement (if required to accurately reflect the bodily characteristic of the individual, e.g., visible sensor measurements). 
       FIG.  18    shows a flowchart of a method for contact tracing based at least in part on a presence logging database. A retrieval of facility zones and times for which a particular user was present in the facility, which is performed at  1801 , may be initiated either upon automated detection of a user having an abnormal bodily characteristic (e.g., elevated temperature) or upon occurrence of other triggering events such as a report from a user and/or a health official to a facility and/or network administrator, that the user has been stricken with a bodily abnormality (e.g., an illness). At  1802 , the retrieved location (e.g., zones) and times are compared with the rolling data of times and locations stored for other users, e.g., in order to find adjacent location within a distance threshold optionally for a time that exceeds a time threshold and generate a result in report  1803 . The result may optionally trigger notification  1804  ( i ) to the particular user, (ii) to users possibly affected by being proximal to the particular user for an excessive amount of time, (iii) to responsible parties of the facility, of the establishment residing in the facility, and/or of the establishment owning the facility and/or (iv) to jurisdictional officials (e.g., health and/or government officials). At times, generation of the report and the optional notification may occur for select type(s) of abnormal bodily characteristics identified (e.g., to fever, and not to abnormal perspiration). 
     In some embodiments, the availability of tracking data for facility occupants is utilized to aid in maintenance of physical distances between occupants (e.g., maintain social distancing above a distance threshold). A user may notify the network (e.g., using a software application—app) of his/her destination. For example, a user sitting at an office desk would like to go to conference room X. The app may use the tracking data and suggest an optimal route that is the one least crowded with occupant, from the current location of the occupant (e.g., desk) to the occupant destination in the facility (e.g., conference room X). The app may use the projected analysis (e.g., using machine learning, occupancy schedule for the facility, and/or activity schedule for the facility) to foresee occupancy of the enclosure during the requested movement time of the requesting user. The app may suggest an optimal route that is the one least crowded with occupant during the expected travel time, from the current location of the occupant (e.g., desk) to the occupant destination in the facility (e.g., conference room X). When the user begins travel from their location (e.g., desk) toward their requested destination (e.g., conference room X), the controller may review a tracking database to check for clusters of other occupants along the projected path (e.g., in real time, during the occupant&#39;s travel). When such a cluster is found, alternative routes may be evaluated to find and suggest another available route to the destinations, which is less crowded. Such less crowded route option may be automatically shared with the user by the app (e.g., pushed to the user). 
       FIG.  19    shows an example of a flow chart  1900  depicting operation for suggesting optimal route to an occupant requesting to reach a destination in a facility in a least crowded route. A target route is input by the occupant in  1901 . An identity and/or route of the occupant may be input (e.g., automatically) by the network (e.g., using sensors(s)) of the facility. The occupant may input his/her current location and/or identity manually to the app. Evaluation of occupant density in various routes in the enclosure from the occupant&#39;s current location to the occupant&#39;s target destination is evaluated in  1902 , followed by identification and suggestion of the least crowded route (e.g., path) to the destination in  1903 . An optional tracking of the route during travel is suggested in  1908  that includes tracking movement of the occupant (e.g., in real time) along the route in  1904 , evaluating occupant density (e.g., in real time) along the route in  1905  and deciding whether a less crowded route is available (e.g., in real time) in  1906 . When a less crowded route is available, the occupant is notified of an optional less crowded route. 
     In some embodiments, the availability of tracking data for facility occupants is utilized to aid in maintenance of physical distances between occupants (e.g., social distancing). As occupants are tracked within a facility, a learning module may compile the typical movements of individuals for various times of day and/or the occurrences of repeating events. Using the learned tendencies for movements of users, the learning module can anticipate where people are going as they move about. When a projected path of movement for a particular user is discerned by the learning module, a controller (e.g., using a processor) can evaluate conditions (e.g., crowded or not) on the expected path. In the event that conditions are crowded in the anticipated path of the user, a (e.g., push) notification may be sent to the user with a recommended route to avoid crowded areas (e.g., to maintain social distancing of the user during his/her taking the path). For example, a user may have a tracking history showing a recurring pattern of moving from their desk to a printer station, from the printer station to a file room, and then from the file room back to their desk. When the user begins travel from their desk toward the printer station, the controller may anticipate such a round trip and then review a tracking database to check for clusters of other occupants along the projected path. When such a cluster is found, alternative routes may be evaluated to find another available route to the destinations which is less or least crowded (e.g., to avoid other people). The alternate route can be automatically shared with the user by the app. 
       FIG.  19    shows an example of a flowchart  1950  depicting operations for suggesting optimal route to an occupant requesting to reach a destination in a facility in a least crowded route. At  1951 , a user ID of an occupant present in the facility is logged. This can be done by identification of the occupant upon entry into the facility, or by any other logging of the occupant (e.g., manual logging by the occupant). While the user is present in the facility, location of the user is tracked at  1952 . As data points accumulate for a user over time, a learning (and predictive) module analyzes the movements of the user as a function of time and location, as the data is built up (e.g., serving as a learning set for the learning module), to learn  1953  movement patterns (e.g., as a function of time) of the occupant in the enclosure. A check is made at  1957  to determine whether a learning module predicts a likelihood of a certain movement based at least in part on tracking of the user (e.g., based on previous movements routes, movement initiation location, movement destination, and/or movement time). If no movement is predicted, then further monitoring and refinement of the predictive model are performed at  1952 . If a certain movement is predicted, then the predicted route is evaluated for occupant density (e.g., for potential interaction with building occupants and/or other potential risks) at  1954 . At  1955 , the crowdedness of occupants in various routes to the predicted destination are determined and compared. The occupant is notified of the least crowded route. If there is no better route available, then further monitoring and refinement of the predictive model and/or crowdedness of the route are performed at  1955 . If a less crowded route is found then a at the occupant is notified at  1956  takeoff an optional better route. Then there is a return for further monitoring and refinement of the predictive model at  1952 . The monitoring can continue whether the occupant takes the route or not. The monitoring can continue in real time during traveling of the occupant along the route. The crowd estimation may consider real time crowdedness and forecasted crowdedness (e.g., using projected analysis such as using machine learning, occupancy schedule for the facility, and/or activity schedule for the facility). 
     In some embodiments, environmental characteristics are monitored using any of the described sensor modalities to find abnormal characteristics of people and/or surfaces in a facility. For example, humidity changes may be monitored as an indication of excessive perspiration of a sick person. Similarity, gases or chemical concentrations can be monitored as indication an of various kinds of illness. In some embodiments, the sensors or sensor ensembles deployed in a facility are used to sense and/or identify the temperatures of designated surfaces that are targets for regular disinfection (e.g., furniture and/or fixture surfaces such as countertops, doors, table-tops, handles, windows, frames, etc.). Such surfaces may be chosen as a result of being significant reservoirs for infectious agents (e.g., pathogens) to collect and potentially be passed on to other occupants, e.g., if not disinfected. The surfaces can be targeted for regular cleaning and monitoring. Monitoring of the surface can be initiated manually or by otherwise detecting a cleaning activity. After cleaning (e.g., using typical disinfectants and/or other liquid) evaporation of the cleaning liquids (e.g. solvents) from the surface may cool the surface. A cleaning event may be detected by measuring surface temperature at a plurality of sample times and comparing a plurality of consecutive samples (e.g., two or more) to detect a temperature drop (e.g., above a threshold and/or temperature drop rate), for example, as the temperature of the surface gets reduced due to evaporation. Once a cleaning event has been identified, an elapsed time since the last cleaning of the surface can be detected. In some embodiments, a surface temperature may be intermittently or (e.g., substantially) continuously measured (e.g., at a predetermined sample rate) to determine how much time elapsed since the last cleaning, and optionally whether the surface requires a second cleaning (e.g., as too much time elapsed from the last cleaning event). 
       FIG.  20    shows a flowchart for one example of a method for monitoring cleaning of a surface. At least one surface to be cleaned (e.g., and disinfected) is identified at  2001 . For example, the surfaces may be designated by a facility manager. At  2002 , sensors (e.g., remote temperature sensors, IR thermal cameras, and/or air temperature sensors) are utilized to measure temperature at or near the surface(s) (e.g., as compared to an ambient (e.g., room) temperature). A check is performed at  2003  to determine whether there has been a predetermined decrease in a measured temperature of a particular surface (e.g., which is not accompanied by a matching decrease in the ambient temperature). The purpose of co-monitoring the ambient temperature may be to exclude the possibility that a surface temperature has dropped in response to a change in ambient temperature. If the surface temperature drops by a predetermined amount more than any concurrent drop in ambient temperature, then it is determined that cleaning has occurred, and the cleaning event is logged at  2004 . At  2005 , an elapsed time since the last cleaning event is compared to a time threshold (e.g., a threshold X, where X is a specified time period according to a requested cleaning schedule). If the elapsed time exceeds the threshold then a notification is sent at  2006  to initiate cleaning. For example, to inform a designated person (e.g., building manager) that cleaning of the surface is overdue. For example, to initiate an automatic cleaning agent (e.g., automatic wiper). After  2005  or  2006 , a time delay  2007  may be optionally inserted before returning to  2002 , e.g., for re-measuring the surface temperature (and optionally also the ambient temperature). 
     In some embodiments, the sensor(s) are operatively coupled to at least one controller and/or processor. Sensor readings may be obtained by one or more processors and/or controllers. A controller may comprise a processing unit (e.g., CPU or GPU). A controller may receive an input (e.g., from at least one sensor). The controller may comprise circuitry, electrical wiring, optical wiring, socket, and/or outlet. A controller may deliver an output. A controller may comprise multiple (e.g., sub-) controllers. The controller may be a part of a control system. A control system may comprise a master controller, floor (e.g., comprising network controller) controller, a local controller. The local controller may be a window controller (e.g., controlling an optically switchable window), enclosure controller, or component controller. For example, a controller may be a part of a hierarchal control system (e.g., comprising a main controller that directs one or more controllers, e.g., floor controllers, local controllers (e.g., window controllers), enclosure controllers, and/or component controllers). A physical location of the controller type in the hierarchal control system may be changing. For example: At a first time: a first processor may assume a role of a main controller, a second processor may assume a role of a floor controller, and a third processor may assume the role of a local controller. At a second time: the second processor may assume a role of a main controller, the first processor may assume a role of a floor controller, and the third processor may remain with the role of a local controller. At a third time: the third processor may assume a role of a main controller, the second processor may assume a role of a floor controller, and the first processor may assume the role of a local controller. A controller may control one or more devices (e.g., be directly coupled to the devices). A controller may be disposed proximal to the one or more devices it is controlling. For example, a controller may control an optically switchable device (e.g., IGU), an antenna, a sensor, and/or an output device (e.g., a light source, sounds source, smell source, gas source, HVAC outlet, or heater). In one embodiment, a floor controller may direct one or more window controllers, one or more enclosure controllers, one or more component controllers, or any combination thereof. The floor controller may comprise a floor controller. For example, the floor (e.g., comprising network) controller may control a plurality of local (e.g., comprising window) controllers. A plurality of local controllers may be disposed in a portion of a facility (e.g., in a portion of a building). The portion of the facility may be a floor of a facility. For example, a floor controller may be assigned to a floor. In some embodiments, a floor may comprise a plurality of floor controllers, e.g., depending on the floor size and/or the number of local controllers coupled to the floor controller. For example, a floor controller may be assigned to a portion of a floor. For example, a floor controller may be assigned to a portion of the local controllers disposed in the facility. For example, a floor controller may be assigned to a portion of the floors of a facility. A master controller may be coupled to one or more floor controllers. The floor controller may be disposed in the facility. The master controller may be disposed in the facility, or external to the facility. The master controller may be disposed in the cloud. A controller may be a part of, or be operatively coupled to, a building management system. A controller may receive one or more inputs. A controller may generate one or more outputs. The controller may be a single input single output controller (SISO) or a multiple input multiple output controller (MIMO). A controller may interpret an input signal received. A controller may acquire data from the one or more components (e.g., sensors). Acquire may comprise receive or extract. The data may comprise measurement, estimation, determination, generation, or any combination thereof. A controller may comprise feedback control. A controller may comprise feed-forward control. Control may comprise on-off control, proportional control, proportional-integral (PI) control, or proportional-integral-derivative (PID) control. Control may comprise open loop control, or closed loop control. A controller may comprise closed loop control. A controller may comprise open loop control. A controller may comprise a user interface. A user interface may comprise (or operatively coupled to) a keyboard, keypad, mouse, touch screen, microphone, speech recognition package, camera, imaging system, or any combination thereof. Outputs may include a display (e.g., screen), speaker, or printer.  FIG.  21    shows an example of a control system architecture  2100  comprising a master controller  2108  that controls floor controllers  2106 , that in turn control local controllers  2104 . In some embodiments, a local controller controls one or more IGUs, one or more sensors, one or more output devices (e.g., one or more emitters), or any combination thereof.  FIG.  21    shows an example of a configuration in which the master controller is operatively coupled (e.g., wirelessly and/or wired) to a building management system (BMS)  2124  and to a database  2120 . Arrows in  FIG.  21    represents communication pathways. A controller may be operatively coupled (e.g., directly/indirectly and/or wired and/wirelessly) to an external source  2110 . The external source may comprise a network. The external source may comprise one or more sensor or output device. The external source may comprise a cloud-based application and/or database. The communication may be wired and/or wireless. The external source may be disposed external to the facility. For example, the external source may comprise one or more sensors and/or antennas disposed, e.g., on a wall or on a ceiling of the facility. The communication may be monodirectional or bidirectional. In the example shown in  FIG.  21   , the communication all communication arrows are meant to be bidirectional. 
       FIG.  22    shows a flowchart for a method  2200  for detecting a perturbation in an environmental characteristic of the enclosure. The method of  FIG.  22    may be performed by an individual sensor of a sensor ensemble. The method of  FIG.  22    may be performed by a first sensor coupled to (e.g., in communication with) a second sensor. The method of  FIG.  22    may be directed by a controller coupled to (e.g., in communication with) the first and/or second sensors. The method of  FIG.  22    begins at  2210 , in which sensor readings are obtained from one or more sensors of a sensor ensemble. At  2220 , readings are processed (e.g., by considering the enclosure, historical reading, benchmarks, and/or modeling) to generate a result. At  2230 , the result is utilized to detect an environmental change (e.g., at a particular time and/or location), and/or to predict future readings of the one or more sensors. At  2240  the result may be optionally communicated, e.g., to an interested party. 
     In particular embodiments, sensor readings from a particular sensor may be correlated with sensor readings from a sensor of the same type or of a different type. Receipt of a sensor reading may give rise to a sensor accessing correlation data from other sensors disposed within the same enclosure. Based, at least in part, on the access correlation data, the reliability of a sensor may be determined or estimated. Responsive to determination or estimation of sensor reliability, a sensor output reading may be adjusted (e.g., increased/decreased). A reliability value may be assigned to a sensor based on adjusted sensor readings. 
     A sensor reading may be any type of reading, such as detection of movement of individuals within an enclosure, temperature, humidity, or any other property detected by the sensor. Sensor readings may be correlated with correlation data. The correlation data may be accessed from other sensors disposed in the enclosure. Correlation data may relate to output readings from a sensor of the same type or a sensor of a different type operating within the enclosure. In an example, a noise sensor may access data from a movement sensor to determine if one or more individuals have entered an enclosure. One or more individuals moving within an enclosure may emit a level of noise. In an example, output signals from a noise sensor may be corroborated by a second noise sensor and/or by a movement detector. Based at least in part on the accessed correlation data, ran analysis (e.g., evaluation) of the environmental characteristic at one or more position of the environment may be made. The one or more positions may correlate to a position of an individual in the environment (e.g., to detect any abnormal bodily characteristic of the individual(s). The environmental characteristic(s) perturbed by the individual(s) in the environment may be detected for any abnormal bodily characteristic. Once the environmental characteristic(s) detected are analyzed for any abnormal bodily characteristic, they may be reported (e.g., as disclosed herein). 
       FIG.  23    shows an example of a controller  2305  for controlling one or more sensors. Controller  2305  comprises sensor correlator  2310 , model generator  2315 , event detector  2320 , processor and memory  2325 , and the network interface  2350 . Sensor correlator  2310  operates to detect correlations between or among various sensor types. For example, an infrared radiation sensor measuring an increase in infrared energy may be positively correlated with an increase in measure temperature. A sensor correlator may establish correlation coefficients, such as coefficients for negatively-correlated sensor readings (e.g., correlation coefficients between −1 and 0). For example, the sensor correlator may establish coefficients for positively-correlated sensor readings (e.g., correlation coefficients between 0 and +1). 
     In some embodiments, the sensor data may be time dependent. In some embodiments, the sensor data may be space dependent. The model may utilize time and/or space dependency of the sensed parameter. A model generator may permit fitting of sensor readings as a function of one or more dimensions of an enclosure. In an example, a model provides sensor profile curves for carbon dioxide may utilize various gaseous diffusion models, which may allow prediction of a level of carbon dioxide at points in between sensor locations. Processor and memory may facilitate processing of models. 
     In some embodiments, the sensor and/or sensor ensemble may act as an event detector. The event detector may operate to direct activity of sensors in an enclosure. In an example, in response to event detector determining that very few individuals remain in an enclosure, event detector may direct carbon dioxide sensors to reduce a sampling rate. Reduction of a sampling rate may extend the life of a sensor (e.g., a carbon dioxide sensor). In another example, in response to event detector determining that a large number of individuals are present in a room, event detector may increase the sampling rate of a carbon dioxide sensor. In an example, in response to event detector receiving a signal from a glass breakage sensor, event detector may activate one or more movement detectors of an enclosure, one or more radar units of a detector. A network interface (e.g.,  2350 ) may be configured or designed to communicate with one or more sensors via wireless communications links, wired communications links, or any combination thereof.

     In some embodiments, bodily characteristics of an individual may be performed at certain locations of the body. For example, temperature may be measured on the forehead. At least one sensor may be disposed in a structure (e.g., fixture) to measure the bodily characteristic. The sensor may focus on the bodily location to sense and/or identify the bodily characteristic. For example, the sensor may focus on the forehead to measure the temperature. The sensor may be directed to focus on a certain lateral (e.g., horizontal) distance from the sensor. The distance may correspond to the distance of the bodily location. The distance may correspond to a designated location of the individual from the sensor. The sensor may be directed to focus on a certain vertical distance from the sensor. The vertical distance may correspond to the vertical distance of the bodily location. The distance may correspond to an average location of the bodily location in the population, e.g., depending on age group and/or gender. 
     In some embodiments, the sensor(s) are operatively coupled to a network. At least one controller operatively coupled to network (e.g., one or more processors operatively coupled to the network) may direct the sensor(s) to focus on the bodily location based at least in part on image recognition of facial landmarks. Facial landmark recognition may utilized one or more (e.g., other) sensors such as sensors for visible and/or IR sensors. The sensors may be configured to identify the individual based at least in part on (i) the individual&#39;s temperature as compared to the surrounding and/or background, (ii) facial landmark features of the individual. The lateral (e.g., horizontal) distance of the individual from the sensor(s) may be estimated using distance between facial features and/or size of facial features, and their comparison to an average population. For example, distance between eyes. For example, size of a pupil. The lateral distance may be estimated using a combination of IR sensor and visible sensor (e.g., camera) data, that identify an individual based at least in part on the heat signature in an environment having a different (e.g., lower) heat signature. The sensor used at least in part to identify the bodily location (e.g., forehead) of the individual can be the same or different from the sensor used to measure the bodily characteristic (e.g., temperature) of the individual. 
     In some embodiments, the bodily characteristic(s) (e.g., temperature) is measured at a lateral distance from the sensor (e.g., at a focal distance from the sensor). The person can be disposed at about the lateral distance of the measurements. The lateral distance may be at least about 0.1 meter (m), 0.3 m, 0.6 m, 0.9 m, or 1 m. The lateral distance of the measurements from the sensor can be between any of the aforementioned distances (e.g., from about 0.1 m to about 1 m). The sensor may have a dwell time during which the bodily characteristic may be measured. The dwell time may be at most about 0.25 seconds (s), 0.5 s, 1 s, 1.5 s, 2 s, 3 s, 4 s, or 5 s. The dwell time may be of any value between the aforementioned values (e.g., from about 0.25 s to about 5 s). The thermal characteristic (e.g., temperature) can be measured with an accuracy of at least about +/−0.7° C., 0.5° C., 0.25° C., or a higher accuracy. The sensor (e.g., as part of a camera) utilized for the measurement may have a horizontal and vertical fields of view. The vertical field of view may be of at least about 30 degrees (°), 40°, 55°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, or 150°. The horizontal field of view may be of at least about 30°, 40°, 55°, 60°, 65°, 70°, 75°, 80°, 90°, or 100°. The vertical field of view may be larger than the vertical field of view. Larger may be by about 1.1 times (*), 1.2*, 1.4*, 1.5*, 1.7*, 1.9*, or 2.0*. 
     At times, a plurality of sensors may be utilized to view the bodily characteristic. The density of measurements over time of the plurality of sensors may be (e.g., substantially) similar. For example, a thermal IR camera and a depth camera may be utilized to ascertain a user&#39;s bodily location (e.g., forehead) and/or measure the bodily characteristics (e.g., temperature). The sensor(s) may be disposed at a location that facilitates focusing on the bodily location (e.g., withing the horizontal and/or vertical field of view of the user). The sensor(s) may be operatively coupled to actuator(s) that facilitate its translation (e.g., horizontally and/or vertically) to adjust capturing the bodily location of the user within a field of view(s) of the sensor. The sensor(s) may be stationary. The translation may be manual or automatic (e.g., using at least one controller). 
       FIG.  25    shows an example of a user  2505  that is subject to measurements of bodily characteristic of temperature. An IR sensors  2502  is disposed in a structure  2503  or attached thereto. A depth camera  2501  is similarly disposed to the structure  2503  or attached thereto. For example, at least one of the sensors can be disposed in a framing (e.g., in a cavity of the framing). For example, at least one of the sensors can be attached to an exterior of the framing. The user  2505  is situated at a designated location  2504  (e.g.,  362  of  FIG.  3   ). The IR sensor  2502  is deposed at an average chin height of a user hi, and at a designated distance di from the designated location  2504 . The IR sensor  2502  has a vertical field of view of 90 degrees. 
     In some embodiments, evaluating bodily characteristic(s) of an individual comprises a plurality of operations. For example, the evaluation can comprise identification of facial landmarks of the user and/or distance of the user from the sensor(s) (e.g., actual and/or expected). A control system may direct the sensor(s) to focus of a bodily location (e.g., based at least in part on the facial landmark recognition and/or distance of the user from the sensor(s)). Once the sensor(s) is configured to focus on the bodily location, the sensor(s) acquire measurement(s) from the bodily location. The measurements may be processed (e.g., adjusted according to various adjustment methodologies) to generate a result of the measured bodily characteristic(s). The result may be compared with a threshold (e.g., value), and a report may be generated. The report may be sent to the user, to authorities, to management, or any combination thereof. The report may contain the adjusted bodily characteristic(s) (e.g., to reflect real value of the bodily characteristic(s)), variance from normal value, and any remedial and/or promotional measure actions (e.g., suggestions and/or directions). The report may be utilized as disclosed herein. The non-manipulated temperature measurements, the processed results, the comparison with the threshold, and/or the report may be saved in one or more databases. The databases may be operatively coupled to the network. The data of the database may be utilized to increase the accuracy of the reported. In some embodiments, the measurements of the bodily characteristic(s) are performed in a contactless manner. 
     In some embodiments, the raw data of the bodily characteristics of a user measured by the sensor does not accurately reflect the actual bodily characteristics of the user. The raw data require adjustment. The adjustment may be performed automatically (e.g., by a processor). The manner of adjustment may be suggested by an artificial intelligence (AI) computational scheme. The AI may comprise a learning module. The learning module may utilize historic measurements of individuals and/or objects having the subject characteristic (e.g., temperature), as compared to a ground truth (e.g., a local thermometer providing an accurate reading). The learning module may utilize synthetic measurements as part of its learning set. The learning module may utilize simulation as part of its learning set. For example, an IR sensor measuring temperature of an individual at a distance at time t, can be compared to a thermometer measuring the individual&#39;s temperature at the time t. The adjustment may consider modeling (e.g., physics modeling) that emulate the subject characteristic measured by the sensors. For example, when the characteristic is temperature, black body radiation at a position of an average individual forehead may be simulated and fed to the learning module as a synthetic measurement as part of its learning set. The learning module (including machine learning) may utilize regression and/or classification algorithms. An output of the machine learning module may be a (e.g., lateral) distance of the subject from the sensor(s) and/or the bodily characteristic (e.g., temperature) measured. 
     In some embodiments, the bodily characteristic is measured using a sensor array (e.g., a camera having a sensor array such as an IR or a visible light camera). The sensor array may comprise at least about 25 pixels, 32 pixels, 800 pixels, 1080 pixels, 1280 pixels, or 1920 pixels in its FLS. (e.g., the array may be 25×25, 25×32, or 32×32 sensor array). The sensor array may comprise at least about 1 megapixels (Mpxl), 4 Mpxl, 8 Mpxl, 10 Mpxl, or 12 Mpxl at its FLS. The sensor may measure a wide operational range, e.g., wide span of the bodily characteristic. For example, the temperature sensor may be configured to measure a temperature spanning from about −40° C. to about 85° C. operational temperature range, or from about −40° C. to about 300° C. operational temperature range. The sensor may be a high accuracy sensor. For example, the temperature sensor may have an accuracy of at least about ±1° C., or ±0.5° C. (or any other temperature accuracy value disclosed herein). The sensor array (e.g., camera having the sensor array) may have an adjustable focus (e.g., automatically adjustable using at least one controller). The camera may have one or more lenses. The sensor array may be sensitive to at least the visible spectrum (e.g., comprise an RGB sensor). The sensor array may be sensitive to at least the infrared spectrum. The sensor may be included in a camera comprising stereo vision. The sensor may be part of a camera. The camera may have a shutter (e.g., a rolling shutter). The sensor may have a small pixel size. The small pixel size may have a FLS of at most about 1.2 micrometers (μm), 1.4 μm, 1.5 μm, 2.0 μm, 2.5 μm, or 3 μm. 
     In some embodiments, the sensor may be free to move. Movements of the sensor may be controller (e.g., automatically by at least one controller). Movements of the sensor may be effectuated by an actuator operatively coupled to the sensor. The sensor may be configured to have at least 1, 2, 3, 4, 5, or 6 degrees of freedom. The six degrees of freedom may comprise forward, backward, up, down, left, right, pitch, yaw, or roll. 
     In some embodiments, a depth camera is utilized to filter noise, and/or to differentiate the user from a background. The camera may comprise stereo vision. The camera may comprise a plurality of sensors spaced apart, e.g., configured to enable the stereo vision capability. The camera module may comprise a processor. The depth camera may include a sensor (e.g., as part of a sensor array) sensitive to the visible spectrum (e.g., Red Green Blue (RGB) sensor), and/or a rolling shutter. The depth camera module may integrate data from IR and visible sensors. The depth camera may comprise IR sensor, IR laser, or a visible sensor. For example, the depth camera may comprise a plurality of visible sensors and one IR sensor and/or laser. For example, the depth camera may comprise a plurality of IR sensors and/or lasers and one visible sensor. The depth camera may comprise a laser (e.g., IR laser). The depth camera may be a web-camera. The depth camera may project and/or sense infrared radiation. The depth camera may utilize comparison of captured data (e.g., sensed information) from two sensors spaced (e.g., horizontally and/or vertically) apart from each other. 
       FIG.  26    shows an example of a flowchart depicting (e.g., contactless) evaluation of a temperature of an individual. Identification of facial landmarks of the user and/or distance of the user from the sensor(s) (e.g., actual and/or expected) is performed in operation  2601 . Focusing the sensor(s) on a bodily location is performed in operation  2602  (e.g., based at least in part on the facial landmark recognition and/or distance of the user from the sensor(s)). Once the sensor(s) is configured to focus on the bodily location, the sensor(s) acquire measurement(s) in operation  2603 , from the bodily location. The measurements are processed in operation  2604  (e.g., adjusted according to various adjustment methodologies) to generate a result of the measured bodily characteristic(s). The result is compared with a threshold (e.g., value) in operation  2605 , and a report is generated in operation  2606 . The non-manipulated temperature measurements, the processed results, the comparison with the threshold, and/or the report are optionally saved in one or more databases in operation  2608 . The databases may be operatively coupled to the network. The data of the database are optionally utilized in operation  2607  to increase the accuracy of the reported. The temperature can be measured, processed, and provided as an output (e.g., to the user) within at most about 0.25 seconds (sec), 0.5 sec, 1 sec, 1.5 sec, 2 sec, 3 sec, or 5 sec.
