Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 593,582, filed on October 27, 2023, which is incorporated herein by reference in its entirety. Technical Field

[0002] The present disclosure relates generally to hazardous condition detectors and, more particularly, to portable fire alarm devices for unconditioned spaces and methods of operating the same. Background Art

[0003] The surge in popularity of electric vehicles (EVs) represents a significant advance in sustainable transportation. However, this shift brings new concerns about fire hazards in garages. The considerable energy stored in EV batteries (e.g., lithium-ion (Li-Ions) batteries) makes EV batteries susceptible to overheating, especially in confined spaces like garages.

[0004] Currently, there are various fire alarm systems that are good solutions for fire detection in conditioned spaces like houses or offices. However, such systems cannot effectively detect potential fire hazards in unconditioned spaces like garages, where factors like dust, pollution, and space affect the accuracy of such fire alarm systems. In addition, conventional fire alarm systems are complex and require a lot of manpower to install and maintain. In addition, conventional fire alarm systems are based on a limited number of sensors, mainly temperature sensors, ignoring other possible scenarios that may lead to potential fire hazards. In addition, the installation cost of conventional fire alarm systems tends to be high due to factors such as their size, design, and power requirements. In addition, power management within conventional fire alarm systems is suboptimal.

[0005] Additionally, due to the complex structure and high power requirements at conventional fire alarm systems, it is difficult to install and / or relocate fire alarm systems.

[0006] Therefore, in view of the above-mentioned problems, there exists a need to provide improved fire alarm systems. Summary of the invention

[0027] Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0028] Figure 1 A schematic block diagram of a portable fire alarm device 100 (hereinafter referred to as “device 100 ”) according to one or more embodiments of the present disclosure is shown. The device 100 includes a sensing unit 102 , a processing unit 106 , an alarm generating unit 108 , an interface module 110 , and a power unit 111 .

[0029] The device 100 may correspond to a compact and easily transportable device designed to detect the presence of fire or smoke and generate an alarm to warn individuals of potential fire hazards. The device 100 may generate an alarm that is intended to provide timely notification in a variety of settings, facilitating rapid evacuation and response to fire emergencies. The device 100 may be a lightweight device with a small form factor. In addition, the device 100 may support a variety of layouts and / or configurations to be appropriately installed at different deployment locations. For example, the device 100 may be installed above a vehicle, a ceiling of a garage / building, a door lock of a garage / building, a door of a garage / building, etc.

[0030] The sensing unit 102 of the device 100 may be configured to receive multiple signals from one or more sensors. The one or more sensors include, but are not limited to, one or more onboard sensors 104 and one or more remotely located sensor devices 116. Examples of the one or more sensors include, but are not limited to, temperature sensors, gas sensors, smoke sensors, and flame sensors. The temperature sensor may be configured to determine a temperature value in an environment. The temperature sensor is configured to monitor and measure temperature changes within an environment. Based on the different types of technologies used in such temperature sensors, temperature sensors may be classified as thermal detectors, thermocouples, resistance temperature detectors (RTDs), infrared temperature sensors, and the like. The temperature sensor is configured to generate an output signal corresponding to the temperature change when the ambient temperature rises above a certain threshold or rises at a rapid rate. A smoke sensor (which may also be referred to as a smoke detector) is a device configured to detect the presence of smoke in an environment. The smoke detector is configured to sense particulate matter and / or aerosols produced by a combustion process to identify initial signs of a fire. The smoke detector may be based on various technologies, such as, but not limited to, ionization methods, photoelectric methods, or combinations thereof. The smoke detector is configured to generate an output signal in response to the detection of smoke in the environment. Gas sensors are configured to detect the presence of potentially hazardous gases in the environment, particularly gases that indicate fire or other hazardous conditions. Gas sensors for fire alarms are designed to detect gases such as, but not limited to, carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), hydrogen (H2), hydrogen fluoride (HF), etc. When the gas sensor detects the presence of a target gas, the gas sensor generates an output signal corresponding to the detection of the target gas. Flame sensors detect the presence of flames or fires by sensing light of a specific wavelength emitted by a flame. Flame sensors operate based on optical sensing technology and are designed to distinguish between the unique characteristics of light emitted by a flame and other light sources, such as sunlight or artificial lighting. Based on the above, the flame sensor generates an output signal corresponding to the detection of a flame in the environment.

[0031] In one embodiment, the sensors discussed above may be implemented as one or more onboard sensors 104. In addition, one or more remote sensor devices 116 may also include one or more of the sensors discussed above. The onboard sensor 104 may be located within the housing of the device 100. The onboard sensor 104 may be integrated with other components of the device 100. The remote sensor device 116 may be remotely located with respect to the device 100. Non-limiting examples of different locations of the remote sensor device 116 may be a battery source of a vehicle, a fuel tank of a vehicle, a ceiling of a garage, and / or near any flammable object / substance. The embodiments are exemplary in nature, and one or more onboard sensors 104 or remote sensor devices 116 may correspond to any suitable sensing device configured to detect fire and / or associated characteristic features. The sensing unit 102 may be configured to receive various output signals from each of the above-mentioned sensors to generate sensor-related data corresponding to the environment. The sensor-related data may indicate information such as, but not limited to, temperature changes, flame detection, target gas detection, and / or smoke detection in the environment.

[0032] The processing unit 106 may be communicatively coupled to the sensing unit 102. The processing unit 106 may include a dedicated processing unit, such as, but not limited to, an integrated system (bus) controller, a memory management control unit, a floating point unit, a digital signal processing unit, etc. In one embodiment, the processing unit 106 may include a central processing unit (CPU), a graphics processing unit (GPU), or both. The processing unit 106 may be one or more general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), servers, networks, digital circuits, analog circuits, combinations thereof, or other now known or later developed devices for analyzing and processing data. In an embodiment, the processing unit 106 may execute a software program, such as manually generated (i.e., programmed) code, to perform the desired operation.

[0033] The processing unit 106 may be configured to receive sensor-related data indicating at least one of a temperature change, flame detection, target gas detection, or smoke detection in the environment from the sensing unit 102. The processing unit 106 may be further configured to compare at least one of the temperature change, flame detection, target gas detection, or smoke detection in the environment with a corresponding predefined criterion to determine whether the received sensor data corresponds to a potential fire hazard. The processing unit 106 may be configured to eliminate the possibility of false positives by effectively utilizing sensor-related data generated based on signals from multiple sensors. The processing unit 106 may verify such signals before utilizing such signals from multiple sensors for determining potential fire hazards. In some embodiments, the processing unit 106 may utilize sensor-related data from at least two sensors to reduce the possibility of false positives. For example, the processing unit 106 may compare the temperature change with a predetermined threshold (e.g., 40F) designated as a primary alarm criterion for a change in a signal from a gas / particle / smoke sensor (e.g., a 10% change relative to a baseline) to confirm whether the alarm is due to a fire or it is a disturbance. Alternatively, an opposite strategy may be employed, wherein the gas / particle / smoke sensor signal is monitored as a primary alarm criterion for a temperature change for confirming an event as a fire or a disturbance. Similarly, instead of using the signal change as the appropriate alarm criteria, the rate of change of the signal over time may be used as an alternative. For example, if the temperature rises 40F in 10 minutes, this may be classified as a disturbance, but if the same 40F rise occurs in 1 minute, it may represent a fire event.

[0034] The device 100 includes an alarm generating unit 108 that is communicatively coupled to the processing unit 106. The alarm generating unit 108 may be configured to generate an alarm based on sensor-related data corresponding to the environment. Examples of alarms generated by the alarm generating unit 108 may include, but are not limited to, the actuation of one or more visual indicators, the actuation of an audio signal, or a combination thereof. In some embodiments, the alarm generating unit 108 may also be configured to generate a sensory alarm to notify a person / user within the environment or associated with the device 100 about a potential fire hazard. In an embodiment, the alarm generating unit 108 may generate an alarm signal, such as, but not limited to, a loud audible sound, a siren, a bell, a horn, or a recorded voice message to notify a user about a potential fire hazard. In another embodiment, the alarm generating unit 108 may generate a visible alarm signal, such as, but not limited to, a bright strobe light, a flashing light, or other visual indicator that provides a visual indication to the user about the potential fire hazard. The alarm generating unit 108 may include and / or be coupled to any suitable device, such as an audio speaker, a light emitting diode (LED), etc., to generate the above-mentioned alarm signal.

[0035] The interface module 110 may be communicatively coupled to the processing unit 106 and / or the alarm generating unit 108. In an exemplary embodiment, the interface module 110 may be configured to establish a connection with a communication module of another device 118 to send the generated alarm to one or more external electronic devices 121. In addition, the other device 118 may include, but is not limited to, a smart lock device, an Internet of Things (IoT) home device, or an external alarm system. Examples of the external electronic device 121 may include, but are not limited to, a smartphone, a tablet, a laptop, a personal computer, a server computer, a building management system, a building security system, etc. The interface module 118 may include a connection port to establish a connection with the communication module of the other device 121. The interface module 118 may be connected to the other device 121 via any suitable connection means, such as a wired connection and / or a wireless connection. Therefore, the alarm may be further relayed through another device, which includes a device for amplifying and enhancing the fire warning signal when appropriate. For example, relaying a fire signal to a thermostat in a home will allow the thermostat to emit a beep (if equipped with a speaker) and / or flash a warning message (if equipped with a display) and / or flash a light (if equipped with an LED light or other lighting). Similarly, an alarm signal can be relayed to a smart home device, which can initiate mitigation actions in response to the fire alarm. For example, an alarm signal at a smart lock can be pre-programmed to open the door, facilitating easier exit from the residence. Similarly, an alarm signal to an automatic / smart garage opener can be used to open the garage door to facilitate exit and alert passers-by of a fire event.

[0036] In some embodiments, the interface module 110 may include an interface that may employ communication technologies such as, but not limited to, code division multiple access (CDMA), high speed packet access (HSPA+), global system for mobile communications (GSM), long term evolution (LTE), WiMax, etc. In embodiments, the interface module 110 may include a network interface to employ a connection protocol, including, but not limited to, direct connection, Ethernet (e.g., twisted pair 10 / 100 / 1000Base T), transmission control protocol / Internet protocol (TCP / IP), token ring, IEEE802.11a / b / g / n / x, etc. In some embodiments, the interface module 110 may be communicatively coupled to one or more external devices 118 via a communication network, which may include, but not limited to, a direct interconnect, a local area network (LAN), a wide area network (WAN), a wireless network (e.g., using wireless application protocol), the Internet, etc.

[0037] The power unit 111 may be configured to supply power to the sensing unit 102 , the processing unit 106 , the alarm generating unit 108 and / or the interface module 110 via an alternating current (AC) power supply 120 , an external direct current (DC) power source 122 , or a DC power source 115 .

[0038] In an embodiment, the power unit 112 may include a pluggable power interface 112 to enable the portable fire alarm device 100 to be connected to an alternating current (AC) outlet to supply power to the sensing unit 102, the processing unit 106, the alarm generating unit 108, and / or the interface module 110 to generate an alarm. The power unit 112 may also include a power interface to enable the portable fire alarm device to be connected to an external direct current (DC) power source 122 to supply power to the sensing unit 102, the processing unit 106, the alarm generating unit 108, and / or the interface module 110 to generate an alarm. In a non-limiting example, the external DC power source 122 may include a battery-powered device of a vehicle. In addition, the power unit 112 may include a DC power source 115 to supply power to the sensing unit 102, the processing unit 106, the alarm generating unit 108, and / or the interface module 110 to generate an alarm. The embodiments are exemplary in nature, and the power unit 112 may be configured to supply the required power to each component of the device 100.

[0039] The power unit 112 may suitably convert power from various sources, such as a DC power source 115, an AC power supply source 120, and an external DC power source 122, to support different power requirements of various components of the device 100. The conversion may include, but is not limited to, AC to DC conversion, DC to AC conversion, power step-up conversion, power step-down conversion, etc. The power unit 112 may also be configured to perform functions such as, but not limited to, power distribution, power backup support, power monitoring, over-current and over-voltage protection, power compatibility conversion, power safety compliance regulations, etc.

[0040] In addition, the device 100 may include a memory (not shown) configured to store data and / or instructions for the processing unit 106 and / or the alarm generating unit 108 to perform the desired functions of the device 100. The memory may include, but is not limited to, a non-transitory computer-readable storage medium, such as various types of volatile and non-volatile storage media, including, but not limited to, random access memory, read-only memory, programmable read-only memory, electrically programmable read-only memory, electrically erasable read-only memory, flash memory, magnetic tape or disk, optical media, etc.

[0041] The embodiments are exemplary in nature, and the apparatus 100 may include any suitable components necessary to effectively and efficiently detect potential fire hazards.
