The present invention relates generally to security systems. More specifically, the present invention relates to emergency notification systems for use by first responders.
An alarm system, such as a smoke detector, is typically used to detect the presence of an unwanted fire in an enclosed structure. In its simplest form, a smoke detector consists of two parts: a sensor to sense smoke and an audible alarm to alert inhabitants of the facility that a fire has started. Smoke detectors typically run off of a 9-volt battery, a lithium battery, or are hardwired into the structure's electrical system.
When a first responder, such as the police or a fire department, is alerted to an emergency within a structure, such as a fire, the first responder typically has no information regarding the interior of the structure. In order to obtain information regarding the structure, such as the number of persons within the structure or the presence of animals, the first responder must seek to obtain the information from inhabitants of the structure or from other persons familiar with the structure. Because obtaining this information is a time-consuming and imprecise exercise, the lives of any humans and animals within the structure may be placed in unnecessary danger.
To ensure the safety of the inhabitants within a structure in the event of an emergency, there is a need for a more effective way for first responders to obtain information regarding the inhabitants of a structure.
The present invention fulfills the need in the art by providing a system comprising: an emergency detector for detecting an emergency event in a structure; an alarm driver coupled to the emergency detector; a latched relay; and a wireless local area network (WLAN) pre-programmed with information regarding the structure, wherein upon detection of the emergency event by the emergency detector, the alarm driver activates the latched relay to transmit power to the WLAN to transmit a wireless signal with the information regarding the structure.
The present invention further provides a device comprising: an emergency detector for detecting an emergency event in a structure; an alarm driver coupled to the emergency detector, wherein an emergency event activates the alarm driver; a latched relay configured to be activated by the alarm driver; a wireless local area network (WLAN) pre-programmed with information regarding the structure, wherein the WLAN transmits a wireless signal with the preprogrammed information upon receipt of power from the latched relay.
In one embodiment, the wireless signal is unencrypted.
In another embodiment, the emergency detector, alarm driver, latched relay, and WLAN comprise a single unit.
In a further embodiment, the emergency detector and the alarm driver are housed in a single unit and the latched relay and WLAN are housed in a separate unit.
In another embodiment, the system and/or the latched relay/WLAN unit further comprises a reset switch and/or a battery.
In a further embodiment, the information regarding the structure comprises physical information on the interior of the structure, including information regarding critical services of the structure and/or information regarding the structure includes information on inhabitants or occupants of the structure.
In another embodiment of the invention, the emergency event is a fire and/or a gas leak.
Additional aspects and embodiments of the invention will be provided, without limitation, in the detailed description of the invention that is set forth below.

The present invention provides an EIC system comprising an emergency detector coupled to a wireless local area network (WLAN) transmitter. When the emergency detector identifies an emergency, the emergency detector sounds an alarm while simultaneously sending a signal to an interface circuit that enables a WLAN to transmit information regarding the structure. Information that may be programmed into the WLAN component of the EIC system, by the user, includes, without limitation, information regarding the dimensions and number of floors of the structure, the location of critical services within and around the structure, the points of access to rooms within the structure, and the number of inhabitants or occupants of the structure.
The system of the present invention is intended to make use of existing fire and police department infrastructure, such as the computers equipped in emergency responder vehicles. The transmitted information from the WLAN enables first responders that arrive at the scene of the emergency to have information regarding the structure and its inhabitants or occupants prior to entering into the structure. The information emitted from the WLAN may be accessed by the first responder by simply detecting available WLAN signals at the scene of the emergency. This signal will preferably be unencrypted and available to any computer or special receiver capable of receiving wireless signals. Wireless signals that are capable of use with the present invention include without limitation, 802.11b, 802.11g, and 802.11n signals. It is to be understood that the EIC system set forth herein is intended to be modified to comply with the latest wireless technology. The WLAN transmitter will continue to emit a signal from the time the emergency detector sounds the alarm until it is reset manually by the user or the first responder.
In one embodiment of the invention, the EIC system is a single unit comprised of an emergency detector, a wireless transmitter, and a battery within the same housing. This single unit configuration has the advantage of being inexpensive to produce; however, it would be subject to or susceptible to damage caused by the emergency event it is detecting (such as for example, a fire). In a preferred embodiment, several single unit EIC devices would be deployed within a structure to provide redundancy. With this embodiment, each individual EIC unit would sound an alarm and present data until it is destroyed by the emergency event.
In another embodiment of the invention, the EIC system of the present invention is comprised of separate components, each of which has its own individual housing. In such an embodiment, one or more emergency detectors would be located in an area or areas of the structure and the WLAN transmitter would be located in a remote location away from the main structure. Within a residential setting, examples of safe locations for the WLAN transmitter would be a garage or a container and/or housing, such as for example a metal box, located outside of the structure. Within a commercial or industrial complex, examples of safe locations for the WLAN transmitted would be a metal box located outside of one or more of the buildings in the commercial or industrial complex.
In one embodiment of the invention, the latched relay 6 and the reset switch 9 are both within the WLAN housing 4. Upon the detection of an emergency by the emergency detector 2, the signal from the emergency detector 2 triggers the latched relay 6, which initiates the transmission of information from the WLAN 5. The WLAN 5 will continue to transmit the information until the WLAN housing 4 is destroyed by the emergency event or the signal is turned off (i.e., unlatched) by the reset switch 9.
In another embodiment of the invention, the WLAN is modified such that the information regarding the structure may be inputted into the WLAN. The modification will include, without limitation, an increase in the available memory of the WLAN. When the WLAN is programmed by the user, the user inputs not only the name of the WLAN, but also the information regarding the structure. Examples 1 and 2 demonstrate information that may be inputted into the WLAN for a residential structure (Example 1) and a commercial structure (Example 2). In a preferred embodiment of the invention, the information is inputted into the WLAN by way of a computer that is connected to the WLAN by way of a device, such as for example, a USB. Under the current IEEE 802.11 wireless standards, WLAN names, which are entered into the service set identifier (SSID) section of the WLAN, are limited to 32 characters. In this regard, one of skill in the art will appreciate that the WLAN of the present invention will be modified to be outside of the current 802.11 standards such that the information described herein, which will typically be in excess of 32 characters, may be inputted directly into and transmitted directly from the WLAN. One of skill in the art will appreciate that the software of the EIC device of the present invention will be different from the software used in IEEE 802.11 standard WLANs and that the hardware for the EIC device of the present invention may also differ from the hardware used to house IEEE 802.11 standard protocols.
In another embodiment of the invention, the WLAN may be programmed with a smart phone or other computerized device that may connected to the WLAN. In a further embodiment, the WLAN may be programmed directly by way of a programming interface device, such as for example, a keypad that may be integrated into the WLAN or sold separately and connected to the WLAN by a USB or other connecting device.
An advantage of the EIC system of the present invention is that the WLAN transmitter need not be as complicated as current commercially available WLAN devices. Commercially available WLAN devices are designed to accept an Internet signal from a source and broadcast it locally throughout a structure. By contrast, the EIC system of the present invention does not require the capability to broadcast an Internet signal; therefore the bandwidth necessary to broadcast an Internet signal is not needed with the WLAN component of the EIC system of the present invention. In this regard, the cost of producing the WLAN component of the EIC system of the present invention is significantly less that the cost of producing WLAN devices for Internet broadcasting. In order to run the WLAN component of the EIC system, all that is required is that the WLAN is capable of identifying itself and has expanded memory to store the necessary information for broadcasting. The emergency detector is preferably powered by a battery, such as for example, a 9-volt battery or a lithium battery, which is replaced periodically.
Where there are multiple detectors within a structure, the emergency detectors may be wired together and/or networked such that when a single emergency detector detects an emergency situation, all of the emergency detectors in the building sound an alarm. In one embodiment, the emergency detector is wired into the electrical system of the structure such that the emergency detector does not require an individual battery to run. The power running the emergency detector must be sufficient to ensure that the signal from the emergency detector will be received by the WLAN. If the emergency detector is powered by the wiring within the structure, such as for example, by a two wire twisted pair, the power should be sufficient to deliver the signal to the WLAN. If the connection between the emergency detector and the WLAN transmitter is electronic, such as for example, by radio-frequency (RF) connectors, such as BLUETOOTH® (Bluetooth Signal, Inc., Kirkland, Wash.) or ZIGBEE® (Zigbee Alliance Corp., San Ramon, Calif.), then the emergency detector must have sufficient power to be able to deliver signal to the WLAN; such additional power may be in the form of a larger battery supply for the emergency detector.
The WLAN will typically require sufficient energy to transmit the information stored therein for at least one hour. The WLAN will typically be powered by an uninterruptible power source (UPS) charged by 110 volt AC power (such as for example in the US) or 220 volt AC power (such as for example in Europe). The AC power will typically be supplied from the electrical system of the structure itself, although AC power from other sources outside of the structure may also be acceptable. For example, where the AC power for the WLAN is supplied from within a single structure in a commercial or industrial complex, upon the trigger of an emergency event within the structure, the WLAN will transmit information to a first responder that is specific to the structure. By contrast, where the AC power for the WLAN is supplied in a common area of a commercial or industrial complex, WLAN within the common area will typically be populated with information for all of the buildings in the complex. In this way, even if the WLAN is triggered from an emergency event detected in only one of the buildings, the WLAN will still transmit information to the first responders about all of the buildings in the complex.
Once the WLAN has been activated, the emergency detector and/or alarm may be destroyed without affecting the broadcast message. By contrast, once activated, the WLAN will continue to broadcast the information stored therein until it is manually reset.
In the hardwired system, the audio signal from the alarm is transmitted to the EIC by way of a wire from the hazard detector to the EIC system (
In each embodiment, the EIC's receipt of the emergency signal from the hazard detector triggers the EIC to transmit information stored within the system by way of a transmitting antenna (
As shown in
In one embodiment of the invention, the external WLAN power supply of the hardwired and RF connected systems is a battery backup (UPS) system that is powered by AC voltage (
Examples of emergency events that may trigger the use of the EIC system and device are, without limitation, fires, smoke, and gas leaks. It is to be understood that the EIC system and device described herein is not intended to be limited to detecting fires and gas leaks, but may be used to detect any other emergency event, such as for example, a home invasion, a residential or commercial burglary, a water leak, a flood, and/or extreme temperatures (either hot or cold) within a structure.
