Abstract: A communication system may include a first radio frequency (RF) device configured to generate a Bluetooth Low Energy (BLE) advertisement responsive to an input event, transmit the BLE advertisement in a BLE advertisement burst comprising a number of transmissions in at least one BLE advertising channel, and discontinue transmission of the BLE advertisement after transmission of the BLE advertisement burst. The system may further include a second RF device configured to scan for the BLE advertisement in the at least one BLE advertising channel, and communicate with the first RF device over a BLE data channel responsive to receiving the BLE advertisement.

Abstract: Systems and methods for operating a communication device. The methods comprise: concealing the communication device and/or at least one cable in a ballistic wearable item (e.g., a ballistic vest) such that the communication device resides in a storage slot for a trauma plate, where the communication device comprises a frame having a cross-sectional profile that matches a cross-sectional profile of the trauma plate by a given amount (e.g., 75-100%); and performing communication operations by a radio module integrated with the frame of the communication device.

Abstract: A radio system includes a portable radio and at least one elongate mounting rail having spaced apart indentations therein. At least one sliding mount includes a mount body having a passageway therethrough and slidably receiving a corresponding elongate mounting rail. The mount body is coupled to the portable radio. At least one spring plunger is carried by the mount body and configured to engage at least one adjacent indentation in the elongate mounting rail.

Abstract: Radio transceiver efficiency is improved by operations involving a calibration mode and an operating mode. The calibration mode includes a first calibration to determine a first optimized tuning control data for a first antenna matching network of a first transmitter when a second transmitter of the portable transceiver system inactive. A second calibration of the first antenna matching network while the second transmitter is active to determine second optimized tuning control data. In operational mode the first optimized tuning control data is used when the second transmitter is not active. The second optimized tuning control data is used when the second transmitter is active.

Abstract: Systems (100) and methods (1400) for detecting removal and attempted removals of an electronic component from an electronic device. The methods comprising: disposing the electronic component (112) on the electronic device such that a conductive surface of the electronic component contacts a ground conductor (802) disposed on a first surface (812) of an internal circuit board (500); using an electro-mechanical member (700) to mechanically couple the electronic component to the internal circuit board and to create an electrical path from the ground conductor to a sensing conductor (800) disposed on a second surface (814) opposed from the first surface of the internal circuit board; and sensing a break in the electrical path.

Abstract: System (201) for mitigating co-site interference includes a co-site filter bank (208) containing filters (2061, 2062, . . . 206n) which can be optionally selectively inserted in an antenna input/output path (2051, 2052, . . . 205n) of two or more transceivers (2041, 2042, . . . 204n). A control system (900) receives information concerning the transceivers. Based on the information, the control system determines whether optional RF filtering should be used to limit RF signals which are communicated to or from the transceivers so as to mitigate co-site interference.

Abstract: A communications device includes a radio frequency (RF) receiver being scannable over a plurality of different frequencies and an analog to digital (AD) converter coupled to the RF receiver. The AD converter is configured to generate a receive bitstream. A processor coupled to the RF receiver and the AD converter. The processor is configured to perform, in parallel, calculating a received power level from the receive bitstream, attempting analog video decoding from the receive bitstream, and attempting digital video decoding from the receive bitstream. The processor is also configured to lock the RF receiver to a current frequency or scan the RF receiver to a next frequency based upon the received power level, and the attempted analog and video decoding.
