Abstract: A battery pack is configured to reduce weight, enhance battery identification, ensure proper placement of a lid retaining the battery, and facilitate battery pack removal. The battery pack has one or more cells that lack an outer coverage except for a polymer sheathing. The battery pack includes a mating notch on a terminal plate and may include a fingernail notch and/or one or more guide rails. The fingernail notch may be a single depression formed to allow a fingernail to slip onto the battery pack, may be a single depression and a ledge that are side-by-side, or may be formed of multiple ledges and/or depressions. There may be a single guide rail or multiple guide rails. Each guide rail preferably has a hollow interior section that is crossed by one or more ribs or segments.

Abstract: The disclosure provides a microphone coupler system for a microphone mounted on a printed circuit board (PCB) for a communication device. The system comprises a boot assembly to enclose the microphone and to direct acoustic signals to the microphone within the communication device, the boot assembly having a coupling section shaped to hold the microphone with the aperture facing upward from the PCB and an elongated section extending from the coupling section. In the system, an acoustic channel for the microphone is formed in part by the boot assembly when the boot assembly is mounted over the microphone. The system may further comprise a platform having an aperture, the platform for mounting on the PCB over the microphone.

Abstract: A switch assembly is provided to actuate a pair of switches using a single push key, e.g. for a camera that utilizes a first switch to activate an image focusing function and a second switch to activate a camera shutter. The switch assembly comprises a contact pad switch and a dome switch that are located laterally to one another. When the push key receives a first downward force, only the contact pad switch becomes activated and a first electric circuit is completed. When the push key receives a second downward force that is greater than the first force, the dome switch collapses and a second electric circuit is completed.
