FIELD OF THE INVENTION
The present invention relates the conducting and guiding of individuals, and in particular to apparatus and methods for conducting and guiding individuals safely.
BACKGROUND
A significant problem faced by hospitality services, entertainment services, and education services is how to conduct and guide individuals through and out of structures, especially in emergency situations. The most common method of conducting individuals consists of the placement of illuminated “EXIT” signs throughout a structure to guide individuals to standard means of egress from the structure, such stairwells, ramps, and emergency exit doors. However, in the case that the standard means of egress are blocked, malfunctioning, or otherwise unavailable, there is typically no practical method of conducting and guiding individuals to alternate means of egress other than sending personnel to intercept individuals and redirect them to available means of egress or making an announcement over a loudspeaker system. Unfortunately, by the time an operator of the structure becomes aware of an issue and can take action, injury or loss of life could occur. This type of system does not take into account that events in a disaster change. Therefore, what is needed is a system that is dynamic and therefore changes as the circumstances change.

DETAILED DESCRIPTION
The present invention is described with reference to the attached figures, wherein like reference numerals are used throughout the figures to designate similar or equivalent elements. The figures are not drawn to scale and they are provided merely to illustrate the instant invention. Several aspects of the invention are described below with reference to example applications for illustration. It should be understood that numerous specific details, relationships, and methods are set forth to provide a full understanding of the invention. One having ordinary skill in the relevant art, however, will readily recognize that the invention can be practiced without one or more of the specific details or with other methods. In other instances, well-known structures or operations are not shown in detail to avoid obscuring the invention. The present invention is not limited by the illustrated ordering of acts or events, as some acts may occur in different orders and/or concurrently with other acts or events. Furthermore, not all illustrated acts or events are required to implement a methodology in accordance with the present invention.
As noted above, a major limitation of existing systems and methods for conducting and guiding individuals safely is that such systems and methods are generally static. For example, signage associated with such systems and methods is typically fixed. Further, another limitation of such systems and methods is that they are designed to directed persons to the “default” means of egress for a structure. For example, in a building, signage is designed to direct individuals to stairwells and emergency exists.
However, in certain circumstances, the user of such “default” means of egress may be impossible or undesirable. For example, if a fire spreads to a stairwell of a building, the stairwell may become unusable. Unfortunately, individuals would still be guided to such stairwell, only to find themselves heading towards the fire instead of away from the fire. In another example, if a gunman enters a structure, there is no way to safely inform individuals on how to exit the structure safely to avoid the gunman.
The various embodiments of the invention address such issues by providing systems and methods for conducting individuals safely. In particular, the various embodiments are directed to systems and methods which utilize data collection to control the operation of guidance devices to conduct and guide individuals through a structure safely. The term “structure”, as used herein, refers not only to any relatively permanent construction such as a building (public, private, residential), but also includes any temporary or mobile structures, on land, sea, or air, such as, but not limited to, temporary or portable buildings, aircraft, or watercraft (whether surface-based or submerged). The present disclosure also contemplates that a “structure” also refers to adjoining or related areas and regions. For example, parking lots, parks, undeveloped or natural areas, playgrounds, or any other features adjacent or connected to a construction can be considered part of the “structure”.
In some embodiments, the systems and methods of the various embodiments can be utilized to provide simple guidance through an area of a structure. One example, is the case of a hotel room. In such a scenario, when persons awake in the middle of the night, they may be disoriented due to the strange surroundings and may have difficulty locating, for example, the restroom. One option is for the person to turn on lights. However, this may result in the person having difficulty going back to sleep. Further, if the person is sharing the room with another, turning on lights may disturb the other person. Accordingly, the various embodiments of the invention can be leveraged to manage such a scenario. This is illustrated below with respect to FIG. 1.
FIG. 1 shows a schematic illustrating one exemplary configuration for conducting and guiding individuals safely in accordance with the various embodiments. In particular, FIG. 1 shows a hotel room 100 configured in accordance with the various embodiments. As in a conventional hotel room, room 100 includes a living area 101 with a bed 102, end tables 104a, 104b, and other items 106a, 106b, 106c, such as dressers, desks, chairs, heating/cooling units, tables, and lamps, to name a few. As shown in FIG. 1, room 100 also includes a restroom 108, a hallway 109, an exit 110, and a closet 112.
In the exemplary configuration of FIG. 1, room 100 can be configured to safely conduct and guide an individual from the bed 102 to the restroom 108 and back without the need for the individual to activate additional lighting that might disrupt the sleep of the individual or others in the room 100. In particular, room 100 is configured such that upon detecting an individual rising in the middle of the night, at least part of the path between the bed 102 and the restroom 108 (designated by arrows 120) is illuminated sufficiently to conduct and guide the individual between these locations.
In some embodiments, this can be accomplished as follows. Data collection devices (not shown), such as motion sensors, can be positioned in one or more locations in room 100. For example, motion sensors can be incorporated into end tables 104a, 104b, the frame of bed 102, or a nearby wall to monitor the areas adjacent to bed 102 where an individual is likely to place his feet (such as areas 122). However, such data collection devices can be positioned elsewhere in room 100. Thus, a signal can be generated by the data collection devices upon detection of the individual in these areas. Thereafter, based on the signal from such devices, guidance devices (not shown) can be activated. For example, floor lighting can be provided to illuminate at least one of areas 122 without significantly illuminating the rest of room 100. The amount of illumination from such guidance devices can be configured so not to be disruptive to sleep of the individual or others in the room. Such guidance devices can also be incorporated into end tables 104a, 104b, the frame of bed 102, or a nearby wall to illuminate areas 122. However, as with the data collection devices, the guidance devices can also be positioned elsewhere in room 100.
In addition to illuminating areas 122, the signal from data collection devices can also be used to illuminate the target location, i.e., area 124 in bathroom 108. While the signal can be used to activate the main lighting in bathroom 108, the present disclosure also contemplates that low-level lighting, such as that for area 122 can be used for area 124 so as not to be disruptive to the sleep of the individual or others in the room.
In some configurations, additional areas can be illuminated. For example, as shown in FIG. 1, area 126, 128, and 130 can also be illuminated to better guide the individual. Further, in some configurations, the illumination can be configured to provide more active guidance. For example, the illumination can be in the shape of an arrow or other shape for guiding an individual in a particular direction.
Deactivation of the illumination of areas 122-130 can occur in a variety of ways. In some configurations, a timer mechanism can be provided so that the illumination is deactivated after a period of time has elapsed. In another configuration, data collection devices (e.g., motion sensors) can also be placed in the target location (i.e., restroom 108) and the deactivation of the areas 122-130 can be delayed until motion is no longer detected in either area.
In some configurations, the illumination of areas 122-130 can be controlled based on time of day or light levels in room 100. In the case of the former, certain times of day can be associated with illumination. Accordingly, the data collection devices and guidance devices can be deactivated during such periods of time. In the case of the latter, one or more photosensors (not shown) can be provided in room 100 in one or more locations. Thus, if light levels in room 100 exceed a certain level, the data collection devices and guidance devices can be deactivated since they are not necessary.
The configuration of FIG. 1 can also be used to provide “on-demand” lighting in other types of structures. For example, in the case of warehouses or other large structures, it may not be efficient to provide lighting of the entire interior of the structure if an individual is only attempting to reach a certain location in the structure. In such configurations, an individual may wish to simply specify a destination and the lighting can be limited to the path required for the user to reach the target location. In such a configuration, the illumination can be maintained for as long as the user is detected in one of the starting or ending location or somewhere along the path therebetween. Further, a control system, such as a computing device, can be provided to allow the user to select the location desired and to control the illumination accordingly.
The configuration of FIG. 1 illustrates a simple application of the principles of the invention. However, the various embodiments can also be used in more complex applications, as shown in FIG. 2. FIG. 2 shows a schematic illustrating an exemplary system 200 for conducting and guiding individuals safely from a structure in accordance with the various embodiments.
As shown in FIG. 2, system 200 operates with one or more structures 202, 204, and 206. Although structures 202, 204, 206 are shown as separate structures, structures 202, 204, and 206 can also be different levels of a single structure, such as in a multi-story or multi-level structure. The goal of system 200 is to direct individuals in structures 202-206 to a safe area 208. To achieve this goal, system 200 can include multiple guidance devices 220 positioned at one or more points throughout structures 202-206.
An exemplary configuration for guidance devices 220 is shown in FIGS. 3A, 3B, and 3C. FIGS. 3A, 3B, and 3C show various views of a guidance device in accordance with the various embodiments. In particular, FIGS. 3A, 3B, and 3C show side cross-section, front, and top views of a guidance device 220 in accordance with the various embodiments. In FIGS. 3A-3C, the guidance device 220 is illustrated in a flush, wall-mounted configuration. Thus, guidance device 220 can include features for mounting on a wall, such as holes or opening for bolts, screws, or any other types of fasteners. Although guidance device 220 is shown in a flush, wall-mounted configuration, the various embodiments are not limited in this regard. That is, the guidance device 220 can be configured for, corner mounting, as illustrated in FIG. 3D. Alternatively, the guidance device 220 can be configured for hanging from a ceiling or mounting on the tip of a pole, tripod, or other vertical support structure. For purposes of emergency lighting, it may be desirable to mount the guidance device 220 at waist height or lower. However, the various embodiments are not limited in this regard and the guidance device 220 can be mounted at any height.
As shown in FIGS. 3A, 3B, and 3C, a guidance device can include display areas 302. The display areas can be configured to include portions 304 for displaying directional information to individuals. As shown in FIGS. 3A-3C, the portions 304 can display the directional information in the form of arrows. In some configurations, the portions 304 can be dedicated elements for a particular direction (up, down, left, right). In other configurations, the portions 304 may be generated by a reconfigurable display 305, such as an LCD display or the like. Display areas 302 can also include, as shown in FIG. 3B, portions 306 for displaying written information. In some configurations, portions 306 can be a part of display 305 or operate separately. As shown in FIGS. 3A-3C, the configuration of each of display area 302 can be different. That is, some of areas 302 can display directional and written information and others of areas 302 can display solely directional information.
In addition to display areas 302, the guidance device 220 can also include one or more illumination sources 308 to illuminate an area in proximity of the guidance device. In particular, the guidance device 220 in FIGS. 3A-3C is configured to illuminate an area beneath the guidance device 220. However, in other embodiments, illumination in other directions can be provided by providing illumination sources 308 along other surfaces of the guidance device 220.
Additionally, the illumination sources 308 can also be configured to illuminate in a fashion that provides directional information. For example, the illumination sources 308 can be configured to illuminate and area in a specific shape, such as an arrow. In another example, the illumination can be provided using colors to direct persons towards or away a guidance device 220. That is, a red illumination can be provided to direct persons away from a location and a green illumination can be provided to direct persons towards a location. Similarly, the sides of guidance device can be illuminated to indicate similar information. That is one side can be illuminated green and the other illuminated red. As a result, an individual approaching the guidance device from the wrong direction will see the red illumination, which signals the individual to turn around and head in a direction away from the guidance device 220. In contrast, an individual approaching the guidance device from the correct direction will see the green illumination, which signals the individual to continue toward the guidance device 220.
In guidance device 220, components 304, 305, 306, and 308 can be controlled via an on-board computing device or controller 312. The controller 312 can be configured to communicate with other devices, including other guidance devices, via wired or wireless communications links. The controller 312 and the other components can be powered via a battery 310. However, the various embodiments are not limited in this regard. In some configurations, power can be provided via an external power source, such as electrical wires. Moreover, such sources can also be used to continuously charge battery 310 to ensure that guidance device 220 can operate even in the absence of an external power source. Additionally, in some configurations, the guidance device 220 can be configured for direct wiring into the electrical system of the structure. Alternatively, the guidance device 220 can be configured to be “portable” in the sense that it can simply be plugged into an existing electrical outlet. In such a configuration, the guidance device 220 can include an electric cord to extend from a location of the guidance device 220 to the outlet. Alternatively, the guidance device 220 can include electrical prongs extending therefrom to as to plug in and mount the guidance device 220 simultaneously.
In some configurations, the guidance device 220 can also include one or more data detection devices, such as sensors 314 and 316 in FIGS. 3B and 3D, respectively. Examples of the types of detection devices include audio monitoring devices, image monitoring devices (still and video, including any optical, light, imaging, or photon sensors), motion or proximity detection devices, an environment monitoring devices (e.g., temperature, humidity), smoke or carbon dioxide detection devices, biological hazard detection devices, a chemical hazard detection devices, and a radiological hazard detection devices, to name a few.
In still other configurations, the guidance device 220 can include a speaker (not shown) for delivering information to individuals audibly. The speaker can operate as an alarm, but can also operate as a means of delivering information to individuals.
In operation, the guidance device 220 can operate in various ways. In one configuration, the guidance device 220 can operate autonomously. That is, based on signals from sensors 314 and 316, the controller 312 can determine how to operate components 304, 305, 306, and 308 and other components therein. In another configuration, the guidance device can be externally controlled by an external controller. That is, the controller 312 can receive signals, over a communications link, which instructs the controller on how to operate components 304, 305, 306, and 308 and other components therein. In such a configuration, the communications link can also be used to communicate signals from sensors 314 and 316 to the external controller. In still another configuration, the guidance device can operate semi-autonomously. That is, the controller 312 can operate components 304, 305, 306, and 308 based on a combination of signals from an external controller and signals from sensor devices 314 and 316. The present disclosure contemplates that not all of components within a guidance device 220 would be activated during each event. For example, in the event that illumination is not an issue, the illumination sources 308 might not be activated.
Referring back to FIG. 2, the operation of the guidance devices 220 within system 200 will be described in greater detail. In operation, guidance devices 220 can initially be in a standby mode. That is, the guidance devices 220 are not configured to provide any particular instructions to users. In some cases, the guidance devices 220 can be configured to provide general messages or information. The placement of the guidance devices 220 in a standby mode can be accomplished via one or more signals from an external controller, such as local controller 210.
During standby operation, the local controller 210 can monitor information indicating the status of one or more parts of the structures 202, 204, 206. The information can be obtained from various sources. For example, as described above, sensors in guidance devices 220 can provide such information. In another example, standalone sensor devices can also be placed throughout structures 202, 204, 206 and place in communication with local controller 210. In yet another example, information can be provided from external sources. For example, a data server 212 can be provided over network 214. The local controller 210 can then communicate with data server 212 and obtain any pertinent information. In still another example, information can be received from user computing device 218, either located within structure 202, 204, 206 or externally and accessed via network 214.
Based on the information the local controller 210 receives, the local controller 210 can determine the occurrence of a triggering event and an appropriate configuration for the guidance devices 220. For example, in the case of a fire, in one portion of the structures 202, 204, 206, the local controller can determine that individuals should be directed outside via particular routes to avoid the fire and/or emergency response personnel. A similar set of actions can take place in the event of other hazards. Similarly, in the event of a medical emergency, it may be useful to direct individuals away from a portion of structures associated with the event and out of the way of emergency response personnel. In some embodiments, the local controller 210 can also receive a signal when emergency response personnel are ready to leave an location associated with a trigger event (e.g., medical personnel ready to transport a victim to an ambulance). In response, the local controller 210 can configure the guidance devices 220 accordingly. In particular, the guidance devices 220 can be reconfigured to guide the emergency response personnel out of a structure as quickly as possible while guiding other persons in the structure to avoid getting in their way.
The local controller 210 can determine the occurrence of a triggering event in various ways. In some configurations, the local controller 210 can simply receive information that explicitly identifies the triggering event and the location thereof within structures 202, 204, and 206. Thereafter, based on the triggering event identified, the local controller 210 can signal the guidance devices 220 to configure them appropriately, according to the type of event and location thereof. In some cases, the information received can also specify the configuration for the guidance devices 220. For example, first responders can interact with the local control 210 to manage the evacuation of a structure in the event of an emergency by a specifying the configuration of the guidance devices.
In other configurations, the local controller 210 can include logic that determines the type of triggering event and location thereof based on the information received. For example, if signals are received from smoke detectors in a certain portion of structures 202, 204, 206, the local controller 210 can determine the occurrence of a fire in the certain portion. Thereafter, the local controller 210 can determine appropriate escape routes, based on the location of the fire, and configure the guidance devices 220 accordingly.
In some configurations, the local controller can determine the occurrence of a triggering event based on an analysis of data from sensors to identify potential hazards. For example, in the case of a gunman entering a building, image recognition techniques can be utilized to detect the presence of a weapon or a known criminal from video data. Similarly, gunshot sounds can be recognized from audio data. Recognition techniques can also be applied to other types of triggering events to recognize the occurrence of such.
Once a triggering event is detected, the local controller 210 can determine how to configure the guidance devices 220 in a variety of ways. In some configurations, the local controller 210 can be preprogrammed with routes for individuals based on particular types of triggering events, the location of such triggering events, and/or the locations of the individuals (i.e., the locations of the guidance devices 220). Thus, individuals in different locations within structure 202, 204, 206, may have different routes. In other configurations, the routes for the individuals can be determined dynamically. That is, the triggering event and location thereof can be determined, all possible routes identified thereafter, and finally a route can be selected based on some criteria. For example, considered criteria can include, but is not limited to, the degree of risk of a route, the expected time to traverse the route, other potential hazards within the structure along the route, number of persons a route can handle, or types of individuals in the structure (e.g., adults versus children).
It should be noted that in the various embodiments, the guidance devices 220 need not be limited to indicating conventional routes, such as emergency exits or stairwells. Rather, to safely get individuals out of harm's way, the local controller 210 can determine that atypical or unconventional routes can be more suitable. For example, guidance devices 220 can be configured to lead individuals to a window on a ground floor or other atypical exit from the structure. In another example, as shown in FIGS. 3A-3C, arrows can be provided to not only route individuals in a horizontal direction, but also to route individuals in a vertical direction. In such cases, the guidance devices 220 can also be configured to provide written information that indicates the atypical exit required of a guidance device 220 can be positioned next to the atypical exit to make clear the type of exit intended for the individual. Similarly, guidance devices 220 can be configured to route users along a longer, indirect path that is safer and avoids the hazard.
In some embodiments, the configuration of guidance devices can be selected based on the types of individuals. For example, in the case of children, the configuration of guidance devices 220 can be selected to be as simple as possible, such as including only arrows. In the case of adults or adolescents, additional information may be provided. Also, as noted above, the route indicated by the guidance devices 220 can reflect the types of individuals. Accordingly, the physical capabilities of the individuals can be considered. For example, in a structure with a large number of children, seniors, or disabled persons, the routes provided are those deemed to be safe from the triggering event and safe from potential injury based on limited physical ability.
Although FIG. 2 shows that a local controller 210 is in communication with and controlling guidance devices 220, the various embodiments are not limited in this regard. In some configurations, a redundant controller 216 can be provided locally or on a network 214, as illustrated in FIG. 2. The redundant controller 216 can be a “clone” of local controller 210 and can be configured to take over operation in the event that local controller 210 is unavailable or compromised. Accordingly, the guidance devices 220 can be configured to communicate with redundant controller 216 over network 214 using wired or wireless communications links. In these configurations, the operation of redundant controller 216 is essentially the same as that of local control 210.
In some configurations, the redundant controller 216 can also be used to enhance or supplement the capabilities of local controller 210. That is, local controller 210 can be used manage information associated with certain types of sensor signals or events and redundant controller 216 can then be used to manage other types of sensor signals or events. For example, as discussed above with respect to the gunman example, certain types of sensor signals can require extended analysis to determine whether or not an event is occurring. In such cases, the analysis can be off-loaded to the redundant controller 216. In contrast, in the case of smoke detection, the amount of analysis required is low. Accordingly, the local controller 210 can be used to manage such an event.
In some configurations, the operation of the various guidance devices 220 can be coordinated so as to provide additional information to individuals. For example, in the case where multiple guidance devices 220 are in view, the operation of each can be alternated to provide “animated” direction information.
Although the various embodiments have been discussed primarily with respect to the use of solely guidance devices 220, the present disclosure contemplates that other devices within structures 202, 204, and 206 can be utilized as well. For example, in some configurations, user computing devices 218, such as desktop computers, laptop computers, smartphones, tablets, and other network connected devices can be in communication with local controller 210. Accordingly, when a triggering event is detected, instructions can be transmitted to such devices. In some cases, the display of such devices can be configured similar to that of guidance devices 220. In other cases, the instructions may simply be a warning or an alert.
Similarly, the system 100 can leverage the existence of other devices, such as that in FIGS. 4A, 4B, and 4C. FIGS. 4A, 4B, and 4C show various views of a bifacial information panel 400 that could be used as guidance device in accordance with the various embodiments. In particular, FIGS. 4A and 4B show exterior and interior views of panel 400. FIG. 4C show a cross-section view of panel 400 mounted in separator 450, such as a door, wall, or window. The exterior portion of panel 400 can include, as shown in FIG. 4A, a display 402, one or more controls 404, and, optionally, one or more sensors 406, such as a camera or microphone. The interior portion of panel 400, as shown in FIG. 4B, can include a display 410, controls 412, and a microphone 414. In conventional operation, the controls 404 can be utilized, by way of example and not by way of limitation, to leave a note to be displayed in display 402, to unlock a door or other entryway associated with panel 400, to announce the presence of an individual to another individuals on the other side of the separator 450, to engage in a conversation with an individual on the other side of the separator 450.
In some embodiments, the panel 400 can also be in communications with nearby guiding devices, a controller for the guidance devices, or both. Accordingly, when an event occurs that results in nearby guiding devices being configured to provide routing information to individuals, the panel 400 can be configured to present, at display 402, the same information as nearby guidance devices or related routing information. Consequently, the panel 400 supplements the existing network of guidance devices. In cases where a large number of instances of panel 400 are provided, such as in a hotel, cruise ship, apartment, or other structure with a large numbers of entryways along a hallway, corridor, or passage, it may be able to reduce the number of guidance devices required.
As noted above, the operation of panels 400 can be coordinated in the same way as guidance devices described above. That is, individuals can be directed to certain routes based on their location or the type of event, or they can be alternatively activated to provide an “animation” effect. In certain embodiments, the presence of sensors 406 can be advantageous. In particular, the sensors 406 in panels 400 can also be utilized to supplement the information obtained from other information sources.
In some embodiments, the interior display 410 can also be used to supplement the guidance devices. That is, the display 410 can be configured by a controller or nearby guidance device to indicate to individuals whether or not it is safe to pass through an associated entryway. Alternatively, if can be used to provide instructions as to whether to shelter in place or exit via atypical means. For example, in the case of a hotel room, the instructions may indicate that individuals should exit out a window (if feasible) or at least retreat to a balcony of the hotel room. Additionally, in cases where isolation is critical, the controller or nearby guidance device can cause the locks on entryway associated with the panel 400 to be locked.

Chipset 560 can also read data from and write data to RAM 575. A bridge 580 for interfacing with a variety of user interface components 585 can be provided for interfacing with chipset 560. Such user interface components 585 can include a keyboard, a microphone, touch detection and processing circuitry, a pointing device, such as a mouse, and so on. In general, inputs to system 550 can come from any of a variety of sources, machine generated and/or human generated.
Chipset 560 can also interface with one or more communication interfaces 590 that can have different physical interfaces. Such communication interfaces can include interfaces for wired and wireless local area networks, for broadband wireless networks, as well as personal area networks. Some applications of the methods for generating, displaying, and using the GUI disclosed herein can include receiving ordered datasets over the physical interface or be generated by the machine itself by processor 555 analyzing data stored in storage 570 or 575. Further, the machine can receive inputs from a user via user interface components 585 and execute appropriate functions, such as browsing functions by interpreting these inputs using processor 555.
