Abstract: An ultraviolet photodetector for a sensor device includes a film deposited on a substrate. The film includes a compositionally graded magnesium-zinc oxide having a ratio of magnesium-to-zinc that decreases between a portion of the film adjacent to the substrate and a portion of the film opposite the substrate for shifting the peak absorption of the film toward the visible wavelengths of the electromagnetic spectrum.

Abstract: A flame detector includes a UV sensor sensitive to solar UV radiation and a secondary sensor sensitive to non-UV radiation. A controller is operatively connected to the UV sensor and the secondary sensor to: signal an alarm in response to receiving input from the UV sensor indicative of a strong UV source and input from the secondary sensor indicative of a weak non-UV radiation source; and suppress an alarm in response to receiving a signal from the UV sensor indicative of a strong UV source and a signal from the secondary sensor indicative of a strong non-UV radiation source.

Abstract: A refrigerant detection assembly operable to detect refrigerant mixed with air includes a housing having an internal cavity fluidly connected with an ambient atmosphere surrounding the housing via an opening. A subassembly mounted within the internal cavity includes an air chamber fluidly connected with the internal cavity, a non-dispersive infrared sensor operably coupled to the air chamber, a printed circuit board, and a heat conduction plate mechanically and thermally coupled to the printed circuit board. At least one insulator is arranged within the internal cavity at a position between a portion of the subassembly and the housing. A shell is connectable to the housing in overlapping arrangement with the opening. The shell has at least one shell opening formed therein such that a flow path extends from the shell opening, through the opening formed in the housing to the internal cavity, and into the air chamber.

Abstract: A fire suppressant storage device (20) comprises: a tank (22) having a first port (40), a second port (70), and an interior (32) for storing fire suppressant. A discharge assembly (46) is mounted to the first port and comprises a discharge valve (48) and a charge conduit (50) at least partially within the interior. The discharge conduit has an interior and an exterior. A liquid level measurement assembly (82; 200; 250; 300; 400) is mounted to the second port and comprises: a tube (100) at least partially within the tank interior and having an interior sealed relative to the surrounding tank interior and an exterior; a float (120; 220) surrounding the tube; and a member (122; 222; 252; 302) axially movable within the tube interior. One of the float and the member comprises an upper magnet (130; 230) and a lower magnet (132; 232). The other of the float and the member magnetically cooperates with the upper magnet and the lower magnet to relatively axially trap the member to the float.

Abstract: A system and method for identifying patterns of indoor air quality sensors. A method includes receiving sensor data from a sensor to determine indoor air quality, the sensor including indoor air quality (IAQ) sensors and identifying a pattern of the sensor data for a period of time. The method may also include comparing current sensor data to the identified pattern of the sensor data and transmitting a message to a user device based at least in part on the comparison to indicate the indoor air quality and the pattern of the sensor data.

Abstract: In a system for measuring a fire suppressant or fire suppression propellant quantity, the system comprising: a base (102); a top plate (106) positioned to support a tank (22) of said fire suppressant or fire suppression propellant; a plurality of springs (112) positioned between the top plate and the base to support the top plate atop the base, the plurality of springs positioned to support the top plate along a range of motion between an extended condition and a retracted condition; a first magnetic member (142) mounted to the base; a second magnetic member (140) mounted to the top plate so that a spacing between the first magnetic member and the second magnetic member decreases as the top plate moves from the extended condition to the retracted condition. At least one of the first magnetic member and the second magnetic member is a permanent magnet. A magnetic field sensor (160) is positioned to detect changes in a magnetic field associated with changes in said spacing.
