Abstract: Systems for protecting electrical components in a detection device are provided. Aspects include a housing comprising a plurality of vents configured to allow ambient air to pass through the plurality of vents in to the housing, a sensing component configured to collect ambient air data associated with the ambient air present in the housing, a printed circuit board, the printed circuit board including a controller and a plurality of electrical components, and a protection cover arranged on at least one electrical component in the plurality of electrical components.

Abstract: An illustrative example monitoring device includes a housing, a detector portion situated in the housing, a substrate situated in the housing and memory supported on the substrate. The memory is configured to contain information regarding operation of the detector portion. The substrate or the memory includes a communication port situated adjacent a portion of the housing. The communication port facilitates obtaining information from the memory. The portion of the housing includes at least one movable section that covers the communication port when the at least one moveable section is in a first position relative to the housing and exposes the communication port when the at least one moveable section is in a second position relative to the housing.

Abstract: Embodiments are directed to a reactive power supply circuit comprising: a capacitor configured to provide an output of the power supply circuit based on power received from a power source, a processor configured to control the output based on at least one of: a state of a first switch that selectively couples the capacitor to the power source based on a detected level of the output, and a state of at least one second switch that selectively couples the capacitor to the power source based on a determination of a state of one or more loads coupled to the output.

Abstract: A telephone switching system for telephone lines in a telephone network that carry voice and associated supervisory information signals. The voice signals are received through one of a plurality of ports under the control of a port event processor and are transferred through a switching arrangement, under the control of a call processor, and transmitted through a port again under the control of the port event processor. The received supervisory information is stored in a port data store memory, which also stores call state and command information. The port event processor retrieves the stored supervisory information and commands from the port data store memory, and processes the supervisory information in response to the commands in at least two functional units, and returns processed information for storage in the port data store memory.
