Abstract: A video recording and communication device includes a camera, a processor, a radar sensor, and memory. The processor executes instructions from memory to cause the device to operate the sensor in a first operational mode in which the camera is maintained in a low-power mode. The processor further detects, using the sensor in the first mode, possible motion of an object within a threshold distance from the sensor. Responsive to the detecting, the processor transitions the sensor from the first mode to a second operational mode. The second mode consumes more power than the first mode. The processor determines, using the radar sensor in the second mode, that the possible motion of the object occurred in a region of interest, in response to which, it transitions the sensor from the second mode to a third operational mode. The third mode consumes more power mode than the second mode.

Abstract: A communication system is described. The communication system includes 5g base stations (gNodeB) which are communicatively coupled to a user equipment (UE) by a multiple radio access technology (multi-RAT) dual connectivity. A first of the gNodeBs is a master gNodeB which relays control signaling from a 5G network core to a secondary gNodeB. To avoid spectral interference of the control signals between the master gNodeB and the secondary gNodeB, the control signals are transmitted according to a tactical waveform protocol selected from the Department of Defense (DoD) Communication Waveform Inventory (2020), such as a common data link (CDL) protocol.

Abstract: An Aircraft Communication and Addressing Reporting System (ACARS) compatible transmitter is disclosed. In embodiments, the transmitter receives outbound (e.g., downlink or uplink) ACARS messages from aircraft end systems and compresses the header/trailer (H/T) and/or text payloads of ACARS blocks (e.g., text messages) or ACARS acknowledgements (ACK)) prior to transmission. For example, the transmitter compresses ACARS blocks by removing fixed markers and encoding variable fields. The transmitter parses incoming text payloads to determine their character distribution and selects a radix alphabet including the ASCII characters used in the text payload.
