    摘要： A system for detecting the presence of combustible gases employing remotely located sensors to provide separate output signals indicative of the gaseous environment at each sensor, the signals being first conditioned and then fed to a channel selection network which causes an output of only the one channel whose signal is the greatest, the output thereof being coupled to indicator devices for indicating high and low levels and for triggering appropriate alarm devices. The system has the ability to disable one channel in the event of any failure therein so as to prevent false alarms and to permit continued function of the system on the operative channel.

    摘要： A fire and gas alarm system utilizing a four-terminal sensing device positioned in the environmental region to be monitored. The sensing device includes a pair of resistance heating wires spaced apart by a conducting core and encompassed by an outer metallic shell. A transformer powers a pair of rectifiers which supply current to both a normally operated standby relay and the four-terminal smoke and gas sensing device. When hydrocarbon vapors or smoke impinges upon the metallic shell of the sensing device, the resistance between the pair of heater wires drops to operate a relay and produce an alarm indication. Upon failure of a.c. power, the standby relay is released to connect battery power to the circuit and insure continued operation in response to an alarm condition.

    摘要： The described invention relates to a computer-implemented method for determining fire safety and occupant safety information, comprising: receiving data from a plurality of Appliances, each equipped with thermal sensors, carbon dioxide detectors and real-time voice communication capabilities, arranged within a building and configured to detect locations of elevated temperature and ambient carbon dioxide levels within the building; wherein one or more of said Appliances are arranged to detect elevated temperatures and levels of carbon dioxide indicative of the presence or risk of fire, and one or more of said Appliances are arranged to detect elevated temperatures indicative of body heat and carbon dioxide levels indicative of respiration and therefore the presence of one or more people, and enabling communication between occupants and a remote person to determine any special medical priorities of said occupants; analysing the received data to determine a first location corresponding to the presence or risk of fire and a second location corresponding to the presence of one or more people; using data corresponding to the first and second locations to construct virtual (i.e., computer-generated) dynamic real-time models of the current state of the fire and probabilistic models of the likely physical development of the fire, and by reference to pre-determined policies defining courses of action to be taken in different fire hazard scenarios, communicating and representing data according to the appropriate policy response. Furthermore, proposed firefighting interventions can be sent as data to the processing unit and the impact of such interventions can be included in the probabilistic fire models, enabling real-time simulation of the impact of said proposed interventions and interpretation of the likely results, using machine learning to improve the accuracy of the simulations. In this way, evacuation priorities and firefighting methods can be better targeted and occupants can be more safely evacuated from the building; resulting in reduced injury risk for occupants and firefighters due to enhanced intelligence on the status and likely development of the fire.
