BACKGROUND OF THE INVENTION
People in emergencies may request help by calling a designated emergency number, for example, a three-digit number like 911 or a direct local access telephone number (i.e., a telephone number tied to a specific emergency dispatch center). With the advent of mobile communication devices (e.g., mobile phones or wearable devices), emergency dispatch centers are receiving a large number of calls from such devices but are poorly equipped to augment their ability to respond to emergencies using currently available technologies.
SUMMARY OF THE INVENTION
Present day wearable devices (e.g., the Apple Watch®) include capabilities to sense and measure health indicators about a user. Such health indicators may include pulse-rate, heart-rate, elevation, movement patterns, the amount of daily movement, temperature, and blood oxygen levels. Present day wearable devices may measure such health indicators using sensors, such as photodetectors operating in the visible and infrared spectrums of light to measure reflection back of certain light emitted by the device, and accelerometers to measure displacement of the device. Wearable devices may also include geographic positioning systems such as GPS to track the geographic location of the device.
Increasingly, many residential spaces, office buildings, and public spaces are equipped with a variety of sensors, for example, temperature sensors or motion sensors. In many instances, these sensors also have the ability to communicate their sensed information over wireless channels, for example, over Bluetooth® or Wi-Fi communication, or over wired channels, for example, fiber optic cables using Ethernet technologies.

Any reference to “or” herein is intended to encompass “and/or” unless otherwise stated. Also, the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
As referenced herein, data from a sensor, data from a sensing component, data from a sensor element, and sensor data all refer to sensed information originating from a sensor. Information or data from a sensor are equivalent to sensed parameter value(s).
As referenced herein, “health indicators” or “physiological parameters” are understood to be various attributes or measureable characteristics of the body that measure the health and well-being of a person such as heart rate, pulse, blood pressure, blood sugar or blood glucose level, salt levels in sweat, heartbeat, temperature, sweat characteristics, eye characteristics, breathing, etc. For example, irregular heartbeats may be a sign of a heart attack.
As referenced herein, “environmental characteristics/characteristics” or “environmental parameters” are understood to be various parameters in the environment that is measured by a sensor that provide situational awareness about the emergency situation. For example, environmental characteristics may include the level of parameters such as smoke, carbon monoxide, radioactivity, temperature, water, chemical, etc., that may indicate that there is an emergency situation and/or provide situational awareness regarding an emergency. It is contemplated that advances in technology may lead to sensors for measuring various components in bodily fluids or on the skin to evaluate various health indicators. In addition to the health information, the device(s) associated with the user may have critical information about the user's habit, communications, family and friends, pre-existing conditions, preferences, emergency contacts/instructions, etc.
An emergency response with situational awareness can be more effective and efficient. Currently, EDCs receive limited information about the emergency and the emergency medical technicians (EMTs) with general preparation have to be sent to the scene quickly. It is contemplated that situational awareness about the emergency obtained from the alert will allow emergency response resources to be allocated more efficiently, for example, when a hurricane or tornado hits a large area. In addition, the EMTs may be able to monitor the emergency situation as they are responding to the emergency. For example, an EDC may receive an emergency alert because of a fire. The EDC may also receive information about the location and health of the various people and pets in the house via the situational awareness process from various devices. In responding to the emergency, the EMTs and firefighters are able bring appropriate equipment and manpower and reduce exploration needed for locating the people and pets.
Existing filings, for example, U.S. patent application Ser. No. 14/856,818, titled “METHOD AND SYSTEM FOR EMERGENCY CALL MANAGEMENT,” filed on Sep. 17, 2015 and incorporated herein by reference, take advantage of Voice over Internet Protocol (VoIP) technology to make emergency calls, including multi-media messaging, from user communication devices such as cellular phones to EDCs.
Historically, users have not been able to make VoIP calls to EDCs using wearable devices. Given the widespread use of wearable technology it will be advantageous for users to be able send an emergency alert for assistance, as needed. In addition, wearable devices have situational awareness information about the emergency. Therefore, it will be advantageous for users to be able to send multimedia messages from their wearable device to an EDC via a communication device, such as mobile or cellular phone, tablet computer, laptop or other communication devices. Disclosed herein are systems and processes by which users can effectively use their wearable device to establish an emergency call with an EDC over data communication links such as IP based channels.
It has been found desirable to have a system and associated method that enables users to utilize wearable technologies to initiate voice and non-voice data sessions for the sake of emergency response to an EDC. Such data sessions desirably would include sending and receiving of multi-media messages and confirmation of reception of request for emergency help, receiving an indication of status of a response provided, and conveying meta-data relating to the user, such as location, pre-stored health record and health information from a wearable device, such as pulse-rate, heart-rate, elevation, movement pattern, amount of daily movement, temperature, temperature, and blood oxygen levels etc., and other relevant information about the user of the wearable device.
As referenced herein, “wearable devices” refers to mobile devices or accessories that can be worn or installed on a user's body. In some embodiments, wearable devices may include one or more sensors. A “sensor” is a device that measures a physical parameter and may record and respond to the measurement (e.g., a temperature sensor, a heart-rate monitor, etc.). Wireless sensors disclosed herein include a sensor module and a communication module for sending the sensed and recorded information. As referenced herein, a “user” refers to a person or entity which uses a communicating device or a network service.
As referenced herein, an “Emergency Management System (“EMS”) refers to a system that receives and processes emergency alerts from users and forwards them to the EDC. Various embodiments of the EMS are described in U.S. patent application Ser. No. 14/856,818, and incorporated herein by reference. The “Emergency Dispatch Center (“EDC”) refers to the entity that receives the emergency alert and coordinates the emergency assistance. The EDC may be a public organization run by the municipality, county or city or may be a private organization. The emergency assistance may be in various forms including medical, caregivers, firefighting, police, military, paramilitary, border patrol, lifeguard, security services.
As referenced herein, “multi-media message” refers to data messages that include information in two or more different types of data—text, sound, image, and video. The multi-media message may also include Meta data, user-inputted data and locational coordinates or GPS data. The multi-media message may be unformatted or formatted for ease of transmission and implementation of the emergency response at the EDC. As used herein, “locational information” may include GPS coordinates or cellular triangulation information, Wi-Fi based locationing, an indoor positioning system or any other form of positional information.
Similarly, current capabilities of wireless sensor networks (e.g., Internet of Things networks) do not allow them to send multimedia messages for emergency response. For better emergency response, it will be beneficial for sensors to actively search and find other communication devices capable of communicating over longer distances, such as cellular phones, to initiate a call for emergency response. In addition, sensed parameters from the sensor or another sensor in the sensor network can provide helpful situational awareness information for the emergency response. Various aspects and embodiments disclosed herein include methods and systems which fulfill one or more of these needs.
In some embodiments, the user will be able to download and install a software or application that will initiate the emergency alert by using the disclosed methods. It is understood that the application may be installed on one or more devices in the disclosed system such as a sensor, a wearable device, a cell phone, a tablet, a laptop, etc. In other embodiments, a sensor or a wearable device may be pre-installed with software to enable sending the emergency alert.
Universal Calling Numbers for Sensing Devices
The growing ubiquitous presence of sensors, coupled with the fact that conventional communications to EDCs, for example, PSAPs, are often made via mobile wireless devices or smart devices (e.g., smartphones, tablets, laptops, wearable smart devices, etc.) that offer a rich type of information, for example, multimedia information in addition to voice and text, rather than land-based telephone lines, provides an opportunity for collecting the combined information available at all these devices, regarding an emergency situation at an EDC and/or an EMS, thus improving the response to an emergency situation. As a result, sensed information from various devices placed in homes and office buildings can be extremely useful if communicated to EDCs in the case of an emergency situation. One way to do this is to communicate information from these sensors to a user communication device, for example, a mobile wireless device, and have the mobile wireless device further communicate the information received from these sensors to the appropriate EDCs. However, this method requires two communication “hops” and also depends on the communication between the sensors and the mobile devices being available. At times this is a restriction, and the sensor may be able to send information directly to an EDC, or emergency management system (“EMS”), without the need for first sending this information to a user communication device, for example, a mobile device, and the EDC and/or EMS will be able to directly call the sensor to retrieve real-time and stored information from the particular sensor. Therefore, there is an opportunity for a system and method for providing a universal calling number for various sensors to improve situational awareness for the purpose of emergency response.
Given the increasing adoption of sensor networks, also popularly known as an “Internet of Things” (“TOT”) in office and residential locations to sense and control environmental variables, it has been found desirable in accordance with one or more embodiments that the information sensed from these sensor networks on a periodic basis be used in responding to emergency situations in a real-time fashion. By providing a rich context that is both sensitive to and situationally aware of the emergency situation being responded to, while also offering the ability to query one or more of the many sensors for specific information that may or may not be included in the periodically sensed information from that sensor, and also allowing for reception of a call from an EMS and/an EDC for purpose of responding to an emergency situation, received at the one of many sensors in the sensor network via a data communication network, for example, the Internet, or via a Wi-Fi network, and actively managing this call, aspects and embodiments of the present invention enhances and builds upon the current IOT systems.
Historically, a dispatcher at an EDC, for example, a PSAP or an EMS, has not been able to place a call for requesting information sensed at a sensor in a wireless sensor network, for example, one in an IOT network, in the process of responding to an emergency situation. Further, when calls for requesting emergency assistance are placed via mobile wireless devices there is currently no method to communicate directly with, and extract in real-time, sensed information from the sensors placed in the environment containing the mobile wireless device, for example, an office or residential building, and utilize such information to better respond to the emergency situation. Thus, users have not historically been able to receive benefit from the multitude of real-time sensed information around their environment in the case of an emergency and build on this knowledge to minimize the impact of emergency situations or even avoid emergency situations. Accordingly, if an EDC, for example, a PSAP, wishes to place a VoIP call over a data communication channel to any of the sensors in a wireless sensor network in the process of responding to an emergency situation, it has historically been unable to do so due to the lack of a number to call for communicating with the sensor. Moreover, historically, the EDC and/or the EMS, based on where the user communication device is calling from and when the last update providing identification information, types, capabilities in terms of accessing communication channels, for example, Bluetooth® and Wi-Fi and sending critical sensed data over these channels, calling number and other information of the installed devices at the particular location of the user communication device received at the EDC and/or the EMS, the EDC and/or the EMS would not have information about the call back number, even if one is assigned, to one or more of the sensors in an IOT framework, and hence would not be able to place a data call for requesting sensed information for the purpose of emergency response.
One advantage of the devices, platforms, methods, and media described herein is that they enable sensors in a wireless network to have a phone number assigned to them so that another communication device, for example, a communication device at an EDC and/or an EMS, a smart phone, or a mobile wireless device, can place a data call to a sensor in the wireless network and request sharing of sensed information for the purposes of emergency response from the sensor in the wireless network and upon receiving this information the EDC, for example, a PSAP or an EMS, can actively share this information with emergency response personnel in an real-time fashion to better equip the emergency response personnel to provide an increasingly effective emergency response. It has also been found beneficial to provide a system and method for assigning a calling number, from a pool of numbers, to sensors in a IOT network placed in a user's environment, by an EMS, or in some instances an EDC, for example, a PSAP, so that the sensors can use this number to place and receive data calls, for example, VoIP calls. These calls may be placed from or to an EDC or an EMS in the process of actively responding to a request for emergency assistance from a user communication device of a user in the vicinity of the TOT sensor network that the given sensor is a part of. The sensors in the TOT sensor network may have information that the EMS or EDC can use to more effectively respond to the current emergency situation. Further, it has also been found desirable to provide a method to allow a EMS or an EDC, to maintain a database of the phone numbers and identifying information of the sensors within its service area, including identifying information about the networks, specifically the TOT networks, that contain these sensors, and information about the users, that are in the region of influence of these sensors as defined by the sensing region of these sensors, for example, location information of the users, as identified by the number assigned to their communication devices, home location, IP address, or current geographic location of the communication device of the user, so that these sensors can be useful in providing additional information in the case that a request for emergency assistance is received from a user in their region of influence.
Various aspects and embodiments disclosed herein include methods and systems which fulfill one or more of these needs or desires.
In accordance with one aspect, there is provided a method of assigning a phone number on a permanent basis from a pool of numbers at an EMS or an EDC to sensors in a wireless network that enables these sensors to receive a data call from another communication device, for example, a smart phone or a mobile wireless device at an EDC or an EMS to request additional information from the sensor. The sensor in turn shares sensed information with the EDC or EMS, and upon receiving this information the EDC, for example, a PSAP or an EMS, actively shares this information with emergency response personnel in a real-time fashion to better equip the emergency response personnel to provide an increasingly effective response to a request for emergency assistance. In such an embodiment, the sensor, in a wireless or a wired sensor network, for example a TOT network, has information about the sensor stored at the EMS or the EDC, such that the calling information, for example, a phone number associated with the sensor, is stored at a database at the EMS or the EDC. A telephone number is associated with a particular sensor, for to particular sensing network, and for a particular geographic region. In some instances, the calling information is also associated with certain users, based on the association of the users with the sensors. The association of the users with the sensors may be determined using several factors, for example, location information of the user and the sensor in the sensing network, ownership of the sensor as assigned to the user, a “home location” where the sensor is registered and the user is using as a primary residence. If there is a change in the identifying information of the sensor, for example, the location of operation, the EMS or EDC is notified about this change and the EMS or EDC, makes the appropriate updates in their local databases so that the sensor is associated with the users that are within the region of influence of the sensor and a new phone number is assigned to the sensor if such a need arises due to the change in physical location of the sensor. Further, in such an embodiment, the EMS or the EDC, is able to add sensors to an on-going session hosting the emergency response for a request for emergency assistance between the EMS and the user communication device, and share with these sensors any relevant information, for example, text messages, multimedia messages including multi-media messaging system messages, videos, images, GPS information and any other form of multi-media messages, and also share any information sent from the sensor to the EMS or the EDC, with other sensors included in the data session, with the user via the user communication device, and/or with the first responders assigned to the request for emergency assistance and manage. This information may be shared for the duration of the emergency response and saved for later reference. Further, in such an embodiment, the EMS or the EDC performs a search in the local database at the EMS or the EDC for sensors available in a given geographic area that is in the service area of the EMS or the EDC, and also includes the latest location estimate of the user communication device, as received from the device or from other sources on the network, for example, a cellular network base station, and upon finding sensors that are located in the service area of the EMS or the EDC, and that are also in the vicinity of the latest location estimate of the user communication device, the location environment parameters can be sensed by the sensor. In such an embodiment the EMS or the EDC makes a decision regarding the association with the user via the defined sensing region of sensors in question, and the location information of the users, as identified by the home location, IP address, current geographic location of the communication device of the user, and other factors identifying the location and type of user and the type of the request for emergency assistance so that a sensor can be chosen for the same.
In certain embodiments the sensed parameter, sensed by the sensor of the sensor network, may be a parameter of an environmental characteristic, for example, temperature, pressure, air flow, amount of ambient light in the vicinity of the sensor, amplitude and/or frequency variations of sound vibrations in the vicinity of the sensor, electromagnetic field variations, or other environmental parameters sensed by the sensor.
In certain embodiments, the sensors host an application client that initiates, or responds to, a communication session with the EMS or the EDC and constructs and sends, using hardware provided by the sensor, a message including an indication of the sensed information to the EMS or the EDC.
In certain embodiments, the sensor contacted for requesting sensed information by the EMS or the EDC for purpose of emergency response is assigned a calling number while the request for emergency assistance is being processed by the EMS or the EDC. The sensor uses this phone number for the duration of the session used for responding to the emergency and in some instances continues to keep this number as the calling number for the sensor for other devices, including the EMS and the EDC, to place a data call to the sensor.
In certain embodiments, the sensor network is placed in a residential environment.
In certain embodiments, the sensor network is placed in a corporate office environment.
In certain embodiments, the sensor network is placed in an industrial factory environment.
In certain embodiments, the sensor network is placed in a public space, for example, a public park, museum, shopping mall, or other populated public area.
In accordance with another aspect of the present invention, there is provided a method for the sensor in a sensor network to be assigned a calling number that is able to be used even if the user moves from a given location in one area code to another location in a difference area code, and a data call placed to the sensor from an EMS or an EDC is routed to the sensor in the new area code and the latest location estimate of the sensor is shared with the EMS and/or the EDC.
In certain embodiments, the sensors host an application client that initiates and manages transmission of the warning signal and request for emergency response using hardware provided by the sensor, for example, the communication interface of the sensor, and manages communication sessions with other sensors in the sensor network.
FIG. 1 is a schematic diagram of one embodiment of a wearable device for sending an emergency alert. FIG. 1 is a schematic diagram of one embodiment of a wearable device for sending an emergency alert. The wearable device 102 may have several components including a display and user interface 112 which will allow the user 100 to interact with the wearable device 102. In some embodiments, the display 112 may be a touch screen, which is capable of displaying information and taking user input. In some embodiments, the user interface 112 may have physical and/or soft-buttons such as buttons for activating and deactivating an emergency alert or for sending a request for emergency assistance to local emergency responders. In addition, there may be buttons for sending an indication of the emergency including the type of emergency (e.g., fire, medical, police, car crash, etc.) to emergency responders. In some embodiments, the wearable device 102 may send situational information about the emergency situation for effective and efficient emergency response.
In some embodiments, the wearable device 102 includes one or more sensors 122 for sensing various health indicators of the user 100 or other people in need. Health indicators may include various attributes of the body that measure the health of a person such as heart rate, pulse, blood pressure, blood sugar, etc. In some embodiments, the sensor 116 may sense environmental characteristics in the area where the user 100 is located. Environmental characteristics may include the level of parameters such as smoke, carbon monoxide, radioactivity, temperature, water, chemical, etc., that may indicate that there is an emergency situation and/or provide situational awareness regarding an emergency. For example, the sensor 116 may include a pulse-rate sensor, a blood pressure sensor, a blood oxygen sensor, a heart-rate sensor, a temperature sensor, a smoke detector, a carbon monoxide monitor, a gyroscope, an accelerometer, etc.
In some embodiments, the sensor 116 may trigger an emergency alert based on sensed information. The wearable device may send the emergency alert using the network element 118. The network element 118 (e.g., an antenna and associated components, Wi-Fi, Bluetooth®, etc.) may send and receive information to the Internet and/or nearby IoT and other devices. In some embodiments, the network element may scan the airways to detect and communicate with communication devices and routing devices in the vicinity.
In some embodiments, the wearable device 102 may include one or more software applications 104 for sending the emergency alert. The application 104 may be pre-installed in the wearable device 102 or may be downloaded and installed by the user 100. It is contemplated that the user 100 or a healthcare provider or caregiver may provide information (e.g., a prioritized list of communication devices, threshold ranges for various health indicators or environmental characteristics) into the application 104 that may be used during an emergency situation. Various embodiments of the application 104 will be described and depicted later.
In some embodiments, the wearable device may include a central processing unit or processor 114, a memory 116 (e.g., an EPROM memory, a RAM, a solid-state memory). In some embodiments, the wearable device is equipped with a global positioning system (GPS). The GPS may generate and collect locational information that may be sent with the emergency alert.
In some embodiments, the wearable device 102 may include various accessories 124 that may allow various functionality and customizations. The accessories 124 may include a microphone (e.g., for input of voice from user 100), a camera 1611 (e.g., for input of gestures commands or pictures from the user 100), speakers, fingerprint reader, USB/micro-USB port, headphone jack, a card reader, SIM card slot, etc.
The wearable device 102 may be worn by the user 100 or attached to his or her body. In some embodiments, the wearable device 102 may have a holster 126 (not shown) that can be strapped to the user's body parts (e.g., wrist, leg, waist, head, fingers, etc.). After an emergency alert is initiated either by a user or triggered in another way, the sensor or wearable device may search for a communication device that can send the emergency alert. FIG. 2 is an illustration of one embodiment of the invention showing a wearable device 202 communicating with other devices through direct and indirect communication links. An indication of an emergency alert from a wearable device 202 may be sent to a communication device 206 wherein a suitable data communication link 222, for example a digital communication session setup using a Transport protocol for example Transmission Control Protocol (TCP), may be established between the wearable device 102 and the communication device 101. The user 200 may initiate an emergency alert using an application client 204 installed on the wearable device 202, the application client 208 on a communication device 206 (e.g., a mobile phone), a tablet, a laptop or desktop and other such devices. It is contemplated that an application could be hardwired into the wearable device 102 for initiating the emergency alert.
In some embodiments, the application client 204 may include a display and user interface 212 and be capable of displaying a plurality of user-friendly buttons or soft keys 213, each button corresponding to a particular type of emergency situation. Selection of a button 213 by the user 200 may cause an emergency indication to be sent to the communication device 101 based on the emergency associated with the button. In some embodiments, the user 200 may initiate the emergency alert by pressing a button 215 on the interface 218 in the communication device 206 with application 208.
In some cases, the wearable device 202 may be connected to a data network and/or the Internet and may be able to send the alert to the EDC via EMS. However, in many cases, the wearable device may not be able to directly send the emergency alert because it may not have the capability or due to inadequate connectivity. In such cases, responsive to selection of one of the buttons 213, the wearable device 202 may search for a communication device 206, for example, a mobile phone, using either a direct wireless data communication link 222 or an indirect data communication link 224, 226 via a routing or intermediary device 219, such as a Wi-Fi router. The wearable device 202 may first attempt to locate and establish a data communication link, for example, a Wi-Fi, Bluetooth®, an “ad-hoc wireless mesh”, ZigBee, PAN, or any other form of a wireless communication protocol-based communication session with the communication device 206 utilizing a direct wireless data communication link 222.
In some cases, the direct wireless data communication link 222 cannot be established with a communication device 206 or the quality of the data communication link 222 is not good. For example, the communication device 206 may be too far from the wearable device 202. The wearable device 202 may evaluate the quality of the data communication link 222 based on various link quality parameters such as a received signal strength indicator, channel latency, error-rate and so on. When the quality of the data communication link 222 is insufficient, the wearable device 202 may initiate a data communication link with a computer networking device or routing device 210, such as a Wi-Fi router a hub or other such computer networking devices, and may establish an indirect data connection 224, 226 with the communication device 206 via the computer networking device 210. Once a data communication link is established with the communication device 206 (e.g., through exchange of control signals), the wearable device 202 sends an initiation of an emergency alert to the communication device 206 and actively manages the data communication link between the wearable device 202 and the communication device 206. If the wearable device 202 detects that an established indirect data communication link 224, 226 is not performing as needed and a direct data communication link is available with other communication devices in the vicinity, the wearable device 102 may attempt to establish communication with such devices (not shown).. Thus, the wearable device 202 establishes a communication link with a communication device 206 or the routing device 210, both of which may act as the connected device.
FIG. 3 is an illustration of one embodiment of a method for sending an alert to an emergency dispatch center (“EDC”) by a wearable device 202 using a communication device 206 (see FIG. 2). In some embodiments, one individual (e.g., user 200) may be the primary user for both communication device 206 and wearable device 202. When an alert is initiated 312 by the wearable device 202, the wearable device 202 may access a list communication devices for sending the emergency alert to the EDC 314. If the wearable device 202 is able to establish a communication link with the first device on the list 316, it will send the emergency alert to be forwarded to the EDC. After the wearable device 202 sends the emergency alert and receives a positive confirmation 318, it actively manages the data session 322.
In some embodiments, upon receiving a positive confirmation, the device 202 waits for status updates from the EDC and actively manages the data communication link 322 between the wearable device 202 and the first communication device 206. If the wearable device 202 does not receive a positive confirmation 318, it waits for a set period and checks for another device on the list 328. If after this period of time the wearable device 102 is not able to find any devices then it waits for the same period of time and tries again 326. If another device is found 333, then the wearable device attempts to establish a communication link 316 with the device 316, 318 to send an emergency alert.
If the wearable device 202 is not able to reach the first communication device on the list after maximum retries (316, 324, 326), the wearable device 202 may move on to the next communication device on the list 328. In some embodiments, if the maximum number of connection retries is reached 324 and the wearable device 202 is unsuccessful in reaching first communication device on the list, the wearable device 202 then attempts to reach a routing device (not shown). If the wearable device 202 is unable to reach any devices, it may cancel the requests and informs the user 332.
FIG. 4 is an illustration of one embodiment of the system for sending an emergency alert via different types of communication devices. A sensor 412, installed with application 414, senses an emergency situation, either via the sensed parameter values by the sensing component of the sensor 412. In some embodiments, the sensor 4122 may be sensing a parameter which is an environmental characteristic, (e.g., temperature, motion, smoke, carbon monoxide, etc.). In some embodiments, the sensor 412 may be sensing a health indicator such as a pulse/heart-rate, a blood pressure, a blood glucose, etc. The user 400 may also initiate the emergency alert using button 419 on the sensor 412 or 415 on the communication device 406.
In some embodiments, the sensor is a wearable device. In some embodiments, the emergency alert may be a multi-media message including situational awareness information to allow for effective and efficient response. In one aspect, the emergency alert may include a request for emergency assistance, one or more information about the user or administrator, one or more locational information and one or more sensed parameters. In some embodiments, the multi-media message includes different types of data including text, image, sound and/or video. In some embodiments, the sensed data may include current and previously sensed parameters and/or a moving average (MA) of the sensed parameters.
In some embodiments, the sensor 412 may be a sensor in sensor network or an internet-enabled device. Once the sensor 412 confirms that a request for emergency assistance has to be sent to an EDC or an EMS 452, the sensor 412 may construct a request for emergency assistance and scan the airways for available communication devices 406, 436, 446 or a routing device 410, to associate with and to send the request via communication device 406.
The sensor 412 may analyze the connection with various available devices, for example, communication device 406 (running application 408) or an indirect communication link with another communication device 406 (running application 408) using a Wi-Fi router 410, by estimating the quality of the data communication link (422, 426, 432) based on various link quality parameters, for example, a received signal strength indicator, channel latency, or error-rate. In some embodiments, the user 400 may be primary user of the communication device 406. But, in other embodiments, there may be another person, such as a family member, who may be the primary user of the communication device 406.
Once a suitable communication device (406, 436, 446) for establishing a direct communication link is found or a routing device 410 and communication device 406 is found for establishing an indirect communication link, the sensor 412 connects to the suitable communication device via a communication link (422, 442, 426, 432) and sends the request for emergency assistance to the connected device. If the connected device is one of the communication devices (406, 436, 446), it then regenerates the emergency request to be formatted to be sent over a communication link (424, 446, 428, 434). In some embodiments, the communication links (424, 446, 428, 434) are cellular channels, and may send the request to an appropriate EDC 450 serving the particular locality. If the connected device is a routing device 410, then the sensor 412 associates with the routing device 410 via a Wi-Fi channel. If available, the routing device 410 sends the request for emergency assistance to an EDC 450 (not shown) directly over the communication link 448. In other embodiments, the routing device 410 will send the alert via communication device 406 via communication links 444, 446. Once the EDC 450 (not shown) confirms receipt of the request for emergency assistance, the communication device (406, 436, 446) or routing device 410 may inform the sensor 412 and forward other updates from the EDC 450 (not shown).
FIG. 5 is an illustration of one embodiment of a system for sending an emergency alert. The system includes a sensor 512 connecting to a routing device 510 for sending a request for emergency assistance to an EDC 550. In some embodiments, the sensor 512 with installed application 514 may perform a scan of the airways and choose a routing device 510, for example, a Wi-Fi router, to associate with and send the request for emergency assistance to an EDC 550. The sensor 512 may send an association request to the routing device 510 via communication link 542, once the sensor 512 chooses to associate with the routing device 510 of all the devices available to connect to, based on channel quality indicators, for example, a received signal strength indicator, channel latency, error-rate, etc.
If the routing device 510 requires authentication to be performed, it may send signals to the sensor 512 to indicate that routing device 510 needs authentication to be performed before the request for emergency assistance can be forwarded to an EDC 550. In some embodiments, the user 500 may provide authentication through the sensor 512 or the routing device 510. Once authentication is performed, the sensor 512 may send the request for emergency assistance to the routing device 510, and the routing device 510 in-turn may forward the request to an Emergency Management System (“EMS”) 530 via a communication link 552. The EMS 530 then may determine which EDC 550 to send this request for emergency assistance based on proximity to the location of the emergency, resources and staff available at the EDC, etc. In some embodiments, the EMS 530 may send the request via a data communication link 562 or a combination of a data communication link 106 and a TDM call via a PSTN 564 and a gateway 540. It is envisioned the present system will be able to send emergency alert to EDCs in some municipalities that does not have capacity to receive digital calls. If the EDC 550 does not have digital capacity, the emergency alert has to be sent through an emergency voice call session.
The EMS 530 may then forward a response from the EDC 530 to the routing device 510, and it may forward these responses to the sensor 512. In some embodiments, the EMS may send “positive confirmation” in the form of signaling, http, push notifications, etc., to the sensor 102. The sensor 102 may then respond to these messages by the EDC 115, if the sensor 102 deems that a response is necessary. In some cases, the sensor 102 may display the information on a display and user interface 528 with buttons 529 for the benefit of the user 500. The routing device 510 may then actively manage the data communication link 554 between the sensor 512 and the EDC 550. Active management may involve sending updates from the sensor 512 to the EDC 550, and from the EDC 550 to the sensor 512, as requested by the sensor 512 or the EDC 550 during the length of the emergency call session or communication link. In some embodiments, the user 500, the EDC 550, or the emergency response team may terminate the call session or communication link.
In one aspect, a system is disclosed for sending an emergency alert including a sensor, a communication device, an EMS and an EDC. As shown in FIG. 6, in one embodiment, a sensor 612 comprises a display and user interface 628 with buttons 629 and installed with application 614. The sensing component senses one or more parameters, such as environmental characteristics and/or health parameters and the communication component is able to establish a communication link 622 for sending and receiving information. The communication device 606 with display & user interface 618, buttons 615 and installed application 608 is able to participate in the communication link 622. In some embodiments, the EMS 630 receives the emergency alert from the communication device and for processing and forwarding the emergency alert to an EDC 650.
In some embodiments, the sensor 612 may perform a scan of the airways using the communication module (not shown) and may choose a communication device 606, for example, a cellular communication device, to associate to and send the request for emergency assistance. The sensor 612 may choose to associate with the communication device 606 based on channel quality indicators, for example, a received signal strength indicator, channel latency, error-rate, etc. Then, the sensor 612 may attempt to establish a communication link with the cellular communication device 606.
If the communication device 606 requires authentication to be performed, it will send signals to the sensor 612 to indicate that communication device 606 needs authentication to be performed before it can re-format and forward the request for emergency assistance to an EDC 450. In some embodiments, the user 600 may authenticate the communication through the sensor 612 or communication device 606. After authentication, the sensor 612 may send the request for emergency assistance to the communication device 606. The communication device 606, which is a cellular phone in this case, may in-turn format the request for emergency assistance to be sent over end-to-end communication links, for example a TDM channel or a data communication link based on Internet Protocol. In some cases, the communication device 606 may add other information, for example, location of the cellular device and the sensor, any multimedia information about the geographic location of the sensor 612 (which may be the GPS information in multi-media format) and the communication device 606, any user-inputted information, video feeds of the geographic location, meta-data about the user 600, readings from the sensor 612 and any other available information that can build situational awareness about the emergency. In some embodiments, the readings form sensor 612 may indicate that the emergency situation is stable or becoming acute, or improving. For example, a smoke detector sensor could indicate if the user or others were able to alleviate a fire emergency by using a fire extinguisher.
In some cases, the communication device 606 may forward the re-formatted request for assistance to an EMS 630 via a data communication link 624. Sometimes, the alert may be sent through cell tower 638 and gateway 642 via data communication links 652, 656. The EMS 630 may decide which EDC 650 to send this request based on factors referred to above. In some embodiments, the EMS 630 may send the request to the appropriate EDC 650 via a data communication link 624 or a combination of data communication link 642 and a TDM call via a PSTN 644 and gateway 640. The EMS 630 may then forward a response from the EDC 650 to the communication device 606, and the communication device 606 may then forward these responses to the sensor 612. The sensor 612 may then respond to these messages by the EDC 650, if needed. In some cases, the information may be displayed on a display and user interface 618 on the sensor 612 for the benefit of the user 600. The communication device 606 may then manage the data communication link (e.g., 622, 624, 626) between the sensor 612 and the EDC 650 and send updates. As needed, the sensor 612 and the EDC 650 may continue to communicate during the length of the emergency communication session.
FIG. 7 depicts one embodiment of a method by which a sensor or a wearable device may trigger and send an emergency alert. The sensor 612 (see FIG. 6) may sense environmental characteristics through a sensing component on the sensor 612 and may calculate a moving average (MA) of these sensed values 712.
In some embodiments, the sensor may trigger an emergency alert when the sensed parameter is outside of a predefined threshold range (TR). The threshold range may be inputted by the user, setup during installing and updated by the user or other authorized agents. The advantage of calculating a moving average (MA) is that it will reduce the impact of a few aberrant sensor measurements and trigger the alarm if several measurements are outside the predefined range. It is contemplated that other functions and algorithms may be used in the place of or in addition to MA.
The sensor may then compare the MA to a set of threshold ranges for each environmental variable sensed by the sensor 714. If the MA of the environmental characteristics is within range TR 716, then the sensor may return to sensing the environmental characteristics by waiting for the next sample interval to sense the values and calculate a new MA for the sensed environmental characteristics. If the MA of the sensed environmental value is not in TR, the sensor may activate the emergency alert 718. To send the alert, the sensor may scan the environment around it, by generally scanning the airways for electromagnetic signals, to detect a communication device 722, or a routing device 732 to associate with in order to send a request for emergency assistance to an EDC 734.
In some embodiments, the sensor may compare the sensed parameter to a predefined warning range. In some embodiments, if the sensed parameter is outside of the predefined warning range, the sensor may send a warning signal to the communication device and the warning may be forwarded to an EDC with user input.
If a communication device is found 724 then the sensor sends an association request to the communication device 728. If the association with the communication device is not successful 736, then the sensor may return to scanning the airways 722 for another communication 724 or routing device 732. Upon successful association with the device 736, the sensor sends request for emergency assistance via the communication device 738. The communication device that is used for sending the emergency alert may be referred to as the connected device. The communication device may wait for a response from the EDC via the connected device, and responds to the requests from the EDC 742 via the connected device while also updating the user about any specific messages given by the EDC. When there is no communication device available for association 724, the sensor checks if it has detected a routing device 732. If no routing device is found 732, then the sensor broadcasts a request for emergency response over a communication link available to the sensor via the communication module of the sensor 734. If a routing device is found 732 then the sensor may send an association request to the routing device 728. If the association with the routing device is not successful (act), then the sensor may return to scanning the airways for another communication or routing device 726. Upon successful association with the routing device 103 736, the sensor places a call for emergency assistance. Subsequently, the sensor may respond to requests for information (e.g., temperature, pressure, smoke level, etc.) from the EDC 742 via the connected device while also updating the user.
FIG. 8 depicts one embodiment of a sensor in a network that may broadcast the emergency alert. In some embodiments, the sensor is in a wirelessly connected network such as an IoT network, a wireless sensor network or a wireless sensor and actuator network. A sensor (such as sensor 612 in FIG. 6) may be in a sensor network (not shown). When a sensor receives a request for emergency assistance from another sensor in the sensor network, it re-broadcasts this request, and updates the information in the request, if updated information is available. It is understood that the sensor network may be WSN or WSAN. A sensor in a sensor network may detect reception of a request for emergency assistance at the communication module of the sensor 812. The sensor then compares the “sensor ID” in the received signal to verify if the request is from another sensor in the same, or different, sensor network 814. If the same sensor is the originating sensor of the request 816, then the sensor may check if there is updated situational awareness about the request for emergency assistance 832. The sensor may check the sensed signal at the sensing component or by another method, and upon detecting no new information to send the sensor may stop the process and re-broadcast alert after a wait time 834. If the sensor detects new information about the request for emergency assistance 832, it may construct a new signal representing the updated sensed values and may broadcast this new information along with a re-broadcast of the original request for emergency assistance 826.
Upon detecting that the sensor ID in the request for emergency assistance is different from the receiving sensor's ID 816, the sensor may check if the same request for emergency assistance was broadcast by the sensor within a minimum time-frame prior to reception of the request 818. If the same request for emergency assistance was broadcast 818, then the sensor may checks if there is updated information about the request for emergency assistance 832, either via checking the sensed signal at the sensor module of the sensor or by another method, and upon detecting no new information to send the sensor stops the process and re-broadcast periodically 834. If the sensor detects new information about the request for emergency assistance 832, it may construct a new signal representing the updated sensed values and broadcasts this new information along with a re-broadcast of the original request for emergency assistance 826.
Upon detecting that the received request for emergency assistance was not broadcast by the receiving sensor within a minimum time-frame prior to the time of reception of the request 818, the receiving sensor may sense the environment variables that pertain to this request from the sensor module on the sensor and verifies if this new information will enhance the received request for emergency assistance 822, 824. If the sensor detects new information, it may check if this new information will enhance the request for emergency assistance 824. If the sensor decides that it will enhance the received request for emergency assistance, it may construct a new signal representing the updated sensed values and broadcast this new information along with a re-broadcast of the original request for emergency assistance 826. If the sensor detects that this new information will not enhance the received request for emergency assistance 824 it re-broadcasts the original request for emergency assistance 828.
For example, during an emergency situation such as a fire, the first responders that arrive at the scene may be able to receive the re-broadcast alert with sensed information (i.e., the augmented alert). As the responders approach the site of the emergency, they may activate a Wi-Fi receiver to receive information from smoke sensors in the vicinity. In this way, the first responders may gather additional situational awareness about the emergency and respond appropriately. In some embodiments, the first responders may be able to send a request for information from sensors in the vicinity to identify people and pets in an indoor location during a fire.
In some embodiments, an EMS 630, or an EDC 650 (see FIG. 6), may request situational awareness information from sensors 612, identified to be in the vicinity of the user communication device 606 requesting emergency assistance. FIG. 9 is an illustration of one embodiment of a method for sending a query to a sensor for updated sensed parameters. When the EMS receives a request for emergency assistance from a user communication device for example a wearable device, the EMS may forward it to the EDC 912. Then, the EMS may send a query to a database of IoT devices associated with that location (e.g., address) or user. IoT devices may include temperature sensors, or pressure sensors, which may have addition information about the emergency situation. In some embodiments, the database may include communication devices associated with a physical address or user.
Upon receiving a returned list of IoT devices that may have situational awareness information about the emergency from the database, the EMS may request to establish a communication link with each of these sensors, either directly or via in-directly via an intermediate device for example an routing device hosted at the location of the sensors being contacted 916. When the communication link is established, a communication session with these individual sensors can be held. In the communication session, the EMS may request pertinent information stored on the sensor about the on-going request for emergency assistance that is being responded to. Once the EMS has received information from all, or at least a majority of sensors, the EMS may combine the information received from each of the sensors and share the combined information with the EDC currently serving the request for emergency assistance 932.
In some embodiments, the EDC or EMS may assign unique numbers to each individual sensor so they can be called for information during an emergency. In some embodiments, the unique number assigned to individual sensors may follow a set format wherein the unique number assigned to a given sensor is sensitive to the location, type and housing structure where the sensor is located. In some embodiments, the sensor name can be used to identify the area and building where the sensor is location.
In some embodiments, the wearable device 1002 may attempt to establish communication links with a plurality of communication devices through direct or indirect communication links for sending the emergency alert as shown in FIG. 10. As shown, a wearable device 1002 with installed application 1004 sends the emergency alert to an EDC or EMS 1052 via a communication device 1006 with installed application 1008. As depicted, the communication device 1006 may be a phone, a desktop 1036, a tablet 1046. The wearable device 1002 may maintain a list of communication devices that can potentially be used to send the emergency alert via communication links 1022, 1024, 1026, 1028, 1032,1034. In some embodiments, the wearable device 1002 maintains a prioritized list of communication devices 1006, 10036, 10046, using pre-defined priorities, in the list of communication devices stored at the wearable device 1002. In some embodiments, the user 1000 may identify the communication devices included in the prioritized list and may assign the priority. In other embodiments, without user input, the prioritized list may be generated in the wearable device 1002 based on variables such as proximity, signal strength from the communication devices or “recently connected devices.”
Based on the prioritized list, the wearable device 1002 may attempt to establish a direct data communication link 1022, 1024 with the communication device 1006. Upon a failure to do so, the wearable device 1002 may then attempt to establish a data communication link with a second communication device in the prioritized list of communication devices and so on until a successful data communication link is established between the wearable device 1002 and one of the communication devices and positive confirmation is received from the EDC 1005 (for example, along communication link 1024, 1028, 1034, about the indication of the emergency alert sent by the wearable device 1002. It is understood that “positive confirmation” referred to herein may refer to an acknowledgement (or an “ack” message) or a human-initiated confirmation or analog signal from the EDC. For example, if the EDC 1050 or EMS 1030 (not shown) responds to the emergency alert, the wearable device 1002 may receive SIP signals.
In some embodiments, it is contemplated that the wearable device 1002 may use an algorithm to choose the fastest and most efficient link to send the emergency alert. So, the wearable device 1002 may attempt to establish to communication link with a plurality of communication devices (1006, 1036, 1046 simultaneously. Based on the response time and quality of the response, the wearable device 1002 may choose the best device to send the emergency alert. In some cases, it may be desirable for the wearable device 1002 to send the emergency to a plurality of communication devices (1006, 1036, 1046), simultaneously.
FIG. 11 depicts one embodiment of a method by which a sensor or a wearable device may choose a communication device from a list. For example, the wearable device 1002 may choose the communication device 1006 (see FIG. 10) for establishing a data communication link 1022, 1024 for sending an emergency alert to an EDC 1050. Referring to FIG. 11, when an alert is initiated 1112, the wearable device 1002 may access a list of communication devices 1114, which may be a prioritized list. The wearable device may attempt to reach the first communication device in the prioritized list 1116, 1118. If the wearable device is unable to reach the first device on the list and a maximum number of attempts to reach the first communication device are not exceeded 1118, 1122, then the wearable device may wait for a period and attempt to send the alert 1134, 1136. If the first device is not reachable, the wearable device will find a next communication device in the list reach 1124, 1118. In some embodiments, if a maximum number of retries are reached and all communication devices in the list are attempted to be reached, the wearable device may display an error message to the user (not shown) and cancels the request. If a communication device is reached, the wearable device sends a message including an indication of an emergency alert 1126 via the communication device. Upon positive confirmation from the communication device, the wearable device waits for status updates from the communication device and actively manages the connection 1128, 1132. If a positive confirmation is not received within a specified period of time, a “time_out” may occur (not shown). The wearable device may check to see if there are other communication devices it can connect to 1134, 1136. If other devices are found that the wearable device has not yet attempted to connect to, it may attempt to connect to the first such device in the prioritized list. If the wearable device does not find a communication device in the list that it has yet to attempt to connect (not shown), the wearable device cancels the request and displays an error message to the user (not shown). In some embodiments, in the absence of a prioritized list or when devices from the list are non-responsive, the wearable device may attempt to send the emergency alert through devices that are in the proximity or “recently connected devices.”
FIG. 12 depicts one embodiment of a method by which a sensor or wearable device may prioritize the first communication devices. The wearable device may detect the occurrence of an event, either a periodic time-out of a reception of a signal or a user initiated event for example a request for emergency assistance 1212. The wearable device may then access a list of first communication devices (list L5) 1214 and checks to verify if the list is empty or populated 1216. If the list is empty 1216 then the wearable device may search the wireless channels for detecting another device to pair with 1218, and then verifies if it was able to find another wireless device to pair with 1222.
If the wearable device 102 is able to find a device to pair with 1216 then it checks if the count, of how many cycles the particular pairable device has been found at the given priority level, is greater than a predefined threshold, D_Thresh, 1224 and if the count is indeed greater than D_Thresh 1224, then decrements the value of “wait_period” to next lower value 1226 and waits for the period of time defined by “wait_period” 1232 before detecting another timeout or user based event 1212. If the count is not greater than D_Thresh 1224, then the wearable device compares the SNR values of all the devices currently pairable or communicable by the wearable device in the list (L1) of first communication devices 1238 and selects only the devices with a SNR value of at least the minimum predefined value of “SNR low thresh” in order of the SNR value of each device, and follows this up by comparing the ACK Timeouts of the first communication devices that are selected in act 1238 above 1242 and chooses devices from this list (L2) which have a ACK Timeout value of less than a predefined threshold of “ACK_max_Time”, and after this the wearable device requests its own RSSI values as seen by individual first communication devices in the qualified list of communication devices L2 and selects devices with RSSI levels reported to be higher than a certain predefined value “RSSI_min_level” in the order of the RSSI value to generate a further qualified list L3 of the first communication devices 1242.
The received signal strength indicator (RSSI) is a measurement of the power present in a received radio signal. The wearable device then re-orders the list with the priority that is not based on communication link quality indicators 1244 and generates a list L4 and verifies to see if any of the devices has a changed position in the list of first communication devices (L5) 1246, 1248 and upon not finding any device with a changed position the wearable device waits for the period of time defined by “wait_period” 1232 before detecting another timeout or user based event 1212.
If even one of the devices has a changed position in the list of first communication devices (L5) 1246, then the wearable device 102 re-orders the list L4 of first communication devices 101 as per the updated parameters (list L5) to generate a final list of first communication devices 1248 and then chooses a first communication device from the list that is at the highest priority in the list of first communication devices L5, and associates the wearable device with this chosen first communication device 1252. If the wearable device is not able to find a device to pair with 1222 then it checks if the count, of having not found any pairable device, is greater than a predefined threshold, ND Thresh 1228, and if the count is indeed greater than ND Thresh 1228, then increments the value of “wait_period” to next higher value 1234 and waits for the period of time defined by “wait_period” 1232 before detecting another timeout or user based event 1212. Otherwise, the wearable device may wait for the period of time defined by “wait_period” 1234 before detecting another timeout or user based event 1212 without incrementing the “wait_period” to the next higher value. In some embodiments, if the list of first communication devices (L5) is not empty, then the wearable device checks to see if any of the parameters about any of the devices in the list (L5) are updated, and if none of the devices have any updated parameters then it waits for the period of time defined by “wait_period” before detecting another timeout or user based event. If even one of the devices has an updated parameter, then it may follow the steps outlined for ACT 207 above when the ACT decides “NO” for the question asked.
FIG. 13 depicts one embodiment of a method by which a wearable device may trigger an emergency alert by monitoring a user's health indicators. For example, the alert may be sent to an EDC 1050 via a communication device 1006 by a wearable device 1002 based on a determination of a value of a health indicator of a user deviating from a pre-defined preset acceptable range for the health indicator (see FIG. 10). Referring to FIG. 13, when a value pertaining to a health-indicator is received at the communication device from the wearable device 1312, a first a moving-time average (MTA) of the received values pertaining to this health-indicator is calculated 1314. If the value of MTA_count, a variable named storing the number of times the MTA value has fallen outside a pre-defined range (R) defined for the given health-indicator 1316, is determined to be larger than MTA_U_Thresh, a variable storing the maximum value of MTA_count before a warning signal is issued pertaining to the given health-indicator, MTA_count is reset to the value of MTA_U_Thresh 1318. If MTA_count is less than MTA_U_Thresh, MTA is compared to R, to check if the numerical value of MTA is within the range of values indicated by R 1322. It is understood that the pre-defined range (R) may be inserted by the user or a health-provider. If MTA is not in the range specified by R, then MTA_count is incremented and the value of MTA_period, a variable storing the number of consecutive times the value of MTA was a sub-set of R, is reset to zero 1322. Immediately after MTA_count is compared to MTA_U_Thresh 1338 and if the value of MTA_count is greater than value of MTA_U_Thresh, a warning signal is issued to the wearable device and the EDC by the communication device 101 and the periodicity of reporting of the value of the health-indicator is increased 1342.
If the MTA_count is less than or equal to the value of MTA_U_Thresh, then the system may be instructed to wait for a predefined period of time for the next periodic value of the health indicator 1344. As used herein, the system includes the wearable device 1002 including one or more sensors, the communication device 1006, the EDC 1050 (see FIG. 10), and an EMS (if present). If MTA is in the range specified by R, then MTA_period, a variable referring to a memory location and storing the number of times the MTA value has consecutively fallen inside a pre-defined range (R) defined for the given health-indicator 1322, the MTA_period is incremented 1324 and then compared to MTA_T_Thresh, a variable referring to a memory location and storing a number indicating a particularly high value for MTA_period 1326. If the MTA_period value is less than the MTA_T_Thresh then the system is instructed to wait for a predefined period of time for the next periodic value of the health indicator 1344. If the MTA_period value is greater than the MTA_T_Thresh then the MTA_count is decremented 1328 and compared to MTA_L_Thresh, a variable referring to a memory location and storing a number indicating a particularly low value for MTA_period 1332. If the MTA_count is less than the value of MTA_L_Thresh then an updated warning signal is sent to the EDC or EMS and the periodicity of reporting that particular health-indicator is decreased 1334. If the MTA_count is greater than MTA_L_Thresh, then the system is instructed to wait for a predefined period of time for the next periodic value of the health indicator.
FIG. 14 depicts one embodiment of a method by which a wearable device adjusts the monitoring frequency of a user's health indicators. A wearable device may monitor health-indicators 1412 for the user and the environmental characteristics of the wearable device. On a periodic basis, or based on request from the user or the EDC, the most current sensed values of the predefined health-indicators are observed 1414. These values are then provided to a mathematical function wherein the moving time-average (MTA) of the past certain sensed values of the individual health-indicators is calculated 1414 and in this case, checked to see if the MTA of the pulse-rate, also the primary health-indicator in this embodiment, of the user 100 is out of a predefined range 1416, 1418. If the MTA of the pulse-rate is out of range a predefined maximum range, Max_RPR 1416, the wearable device may issue a warning signal 1442, either displayed at a user-interface of the wearable device or sent to an EDC via a first communication device and an, and then waits for a specific period of time 1432 before sensing the health-indicators and environmental characteristics. If the MTA of the pulse-rate is not out-of-range a predefined maximum range, Max_RPR 1416, the wearable device checks if the MTA of the pulse-rate is out-of-range a predefined minimum range, Min_RPR 1418.
In some embodiments, the wearable device increments a count, “PR_count”, if the MTA of the pulse-rate is out-of-range of the Min_RPR range 1536, and checks to verify if the PR_count has equaled or passed a minimum threshold set for the pulse-rate to be out-of-range from the Min_RPR range 1422. If the PR_count is indeed equaled or passed a maximum threshold set for the pulse-rate, the wearable device issues a warning signal, either displayed at a user-interface of the wearable device or sent to an EDC via a communication device and an EMS, and then waits for a specific period of time 1432 before sensing the health-indicators and environment characteristics. If the PR_count has not equaled nor passed the maximum threshold set for the pulse-rate, i.e. the PR_count is less than the PR_U_Thresh 1422, then the wearable device checks to verify if the MTA value of the heart-rate sensed values is out of range a predefined maximum range 1444.
In some embodiments, the wearable device sends a warning signal or an emergency alert based on the MTA value. If the MTA value of the heart-rate sensed values is indeed out of range a predefined maximum range 1444, then wearable device issues a warning signal 1442 and waits for a specific period of time before sensing the health-indicators and environment characteristics. If the MTA value of the heart-rate sensed values is not out of range of a predefined maximum range 1444, then wearable device updates the EMS with the latest measured values of the pulse-rate and heart-rate, and any other health-indicators, and decreases the periodicity of sensing and reporting health-indicator values 1446.

EXAMPLES
Example 1—Wearable Device Requesting an Emergency Response
Jane Bond, a heart patient, is alone in her home. Jane is wearing a wearable device on her wrist with a pulse sensor, which measures her pulse-rate periodically. The wearable device is installed with an application, which will measure her pulse-rate more frequently when it begins to fall outside a threshold range. The device also has a second sensor, an accelerometer, for detecting motion. Based on her doctor's recommendations, Jane has inputted the threshold range for her pulse and other health indicators into the wearable device. When the pulse is in the normal range, the wearable device will instruct the pulse sensor to measure the pulse-rate less frequently. In addition, Jane's doctor has advised her to strap a heart-rate sensor (an external sensor for the wearable device) to her chest to monitor her heart-rate when she is not feeling well. When worn together, the heart-rate sensor periodically sends her heart-rate values to the application on the wearable device on Jane's wrist. When the pulse-rate and the heart-rate is outside the pre-defined threshhold, it is a sign that Jane's heart is functioning abnormally. As Jane gets up from bed and goes to the kitchen for some water, her pulse rate drops and the wearable device monitors the pulse-rate and heart-rate simultaneously and issues a warning signal when both fall outside of the pre-defined ranges following a scheme. Jane collapses, and the accelerometer on her wearable device detects the fall. Based on information from the pulse sensor and heart-rate sensor indicating that her heart is not functioning normally, the application on the wearable device decides to send an emergency alert. If the wearable device does not have a data signal, it will search for a list of communication devices in a prioritized list. Jane had entered several communication devices including her cell phone, her tablet, her husband's cell phone, and the doctor's emergency line in the list, while the wearable device is also capable of searching for and identifying communication devices that are in the vicinity to augment the list. At this time, Jane's cell phone and tablet are switched off. Her husband has left his cell phone at home and the wearable device goes through the list and establishes a communication link with her husband's cell phone to send the emergency alert augmented with Jane's pulse and heart-rate sensor data so that an ambulance with appropriate equipment can be included in the emergency response. The alert also includes location information from her husband's cell phone. James' cell phone is located in a distant room in the house and the wearable device is unable to establish a direct connection. The wearable device then establishes an indirect connection with the cell phone through the home WiFi® router. The wearable device then sends the emergency alert to the EMS through this indirect connection. The EMS receives the emergency alert and locates the EDC serving her locality using location information from the emergency alert and delivers the alert with a request for assistance to the local EDC. The EMS formats the message into a format that is compatible with the EDC, which is not able to receive digital or data communications. Here, the EDC in Jane's area can only receive voice calls, so the EMS converts the message into a voice message for the EDC. The voice message includes sensed information about Jane's pulse and heart-rate. With relevant situational information in hand (e.g, a medical emergency because a person's pulse and heart-rate is low), the EDC sends first responders with appropriate medical capabilities. On the way, the medical staff send a request to the wearable device through Jane's husband's phone to send them emergency medical and prescription information, which Jane had saved for emergencies. Further, the EMS searches its device location database to locate any IoT devices inside Jane's home. The EMS locates a motion sensor and sends a request for real-time and historical information from the sensor through her husband's phone to share with first-responders. Fortunately, the motion sensor is located in the 2nd floor bedroom where Jane collapsed, and the historical sensor data reveals movement data with time-stamp information that is close in proximity to transmission of the emergency alert to the EMS. The EMS relays this information to the EDC and first-responders who quickly enter Jane's home and go up the stairs to find her. Thanks to the prompt and efficient emergency response augmented with this new technology, Jane is able to make a fast recovery.
Example 2—IoT Network Situational Awareness for Emergency Response
Bob has a network of IoT devices installed in his house, including smoke detectors. He also has a communication device (mobile phone) and a Wi-Fi routing device in the house. The IoT devices are assigned with unique ID numbers and registered in a device location database (DLDB). When a fire breaks out in a basement, the smoke detector in the basement raises an alarm and broadcasts an emergency alert including a request for emergency assistance to the EMS. The EMS looks up the sensor ID in the database and discovers the physical address of the house where the sensor is located. The EMS sends the emergency alert with the address information to the appropriate EDC in a compatible format. To gain further situational information, the EMS looks up other IoT devices in the house and sends data requests for sensed information to those devices. As the EMS receives updated sensor data from the other IoT devices in Bob's house, it is able to monitor the spread of the fire and update the EDC and first responders in real time. In addition to sending the emergency alert, the smoke detector in the basement broadcasts the message to other IoT devices in the network. The smoke detector at the top of the basement stairs detects the broadcast of the emergency alert and adds sensed information (sensor data) about the smoke level and periodically broadcasts an augmented alert and re-broadcasts the message. When first responders approach the house, they are able to communicate with the IoT devices in the house and get updates about the smoke level in different parts of the house so that they can quickly and effectively respond to the fire.
