Abstract: A life safety detector comprising a housing defining a dark photo detection chamber for receiving ambient material, at least one light source configured to emit light into the detection chamber, at least one light sensing device operable to receive light reflected from the ambient materials in the detection chamber; and a processing device coupled to the at least one light sensing device. In a first mode of operation, the light received by the at least one light sensing device within the dark photo detection chamber is indicative of smoke, and in a second mode of operation, the light received by the at least one light sensing device within the dark photo detection chamber is indicative of an indoor air quality.

Abstract: A detection chamber assembly of a smoke detector is provided. The detection chamber assembly includes upper and lower covers, louvers and a corrugated bug screen. The louvers are arranged with the upper and lower covers to define a chamber bound between the upper and lower covers and the louvers. The louvers include a first pair of louvers defining a first space therebetween to permit fluidic ingress to the chamber and a second pair of louvers defining a second space therebetween to permit fluidic ingress to the chamber. The second space is wider than the first space. The corrugated bug screen includes a body disposed about the louvers and a mesh corrugation feature coupled to the body at the second space to permit fluidic ingress to the chamber at the second space and to inhibit bug ingress to the chamber at the second space.

Abstract: A photoelectric smoke detector includes an optics cover that provides a smoke chamber that has a smoke chamber opening, a blocking component is mounted to the optics cover. An inner cover provides a first opening and a second opening. The first opening receives a portion of the blocking component and the second opening is aligned with the smoke chamber opening. A spoiler is received against the inner cover. The spoiler includes at least one of: a U-shaped fin arrangement and a Y-shaped fin arrangement.

Abstract: A temperature sensor used to monitor coolant and an automobile coolant system. The temperature sensor includes a one-piece housing having a sensor portion and a connector portion. A sensor assembly, including a sensor having a pair of terminals connected thereto is disposed within the housing. The sensor portion includes a sensor tip having a configuration conducive to improving thermal transfer from the coolant through the sensor tip to the sensor. A thermally conductive material may also be used to improve thermal or heat transfer to the sensor.
