Abstract: A communication apparatus includes a low power wakeup receiver (LP-WUR) and a processor. The processor is configured to perform operations including: receiving a modulated signal from a network apparatus via the LP-WUR, wherein the modulated signal has a harmonized design that accommodates overlaid waveforms of one or more modulation schemes; and deriving information bits from demodulating the modulated signal.

Abstract: A communication apparatus includes a low power wakeup receiver (LP-WUR) and a processor. The processor is configured to receive signals from a network apparatus via the LP-WUR, and perform operations including: receiving at least one synchronization signal sent by the network apparatus, wherein the at least one synchronization signal comprises at least one of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS); and using the at least one synchronization signal to detect timing of a low power wakeup signal (LP-WUS).

Abstract: A circuit board is adapted for inserting an expansion card with an electrical contact part, a non-electrical convex part, and a positioning part. The circuit board includes a board body, a slot, a release structure, and a transmission mechanism. The slot is disposed on the board body and includes a socket, a connecting end, and an outer surface. The socket is adapted for the electrical contact part to be inserted. The release structure is movably disposed at the connecting end and includes a limiting part. The transmission mechanism is disposed in the socket, adjacent to the connecting end, or adjacent to the outer surface. The transmission mechanism includes a driving member and a linking member. The driving member is adapted for contacting the electrical contact part, the non-electrical convex part, or the positioning part. The linking member is disposed between the driving member and the release structure.

Abstract: Examples pertaining to synchronization and radio resource management in mobile communications are described. A user equipment (UE) receives a periodic low power synchronization signal (LP-SS) from a network node via a low-power wake-up receiver (LP-WUR) of the apparatus. Then, the UE performs a synchronization based on the periodic LP-SS via the LP-WUR of the apparatus in an event that a main radio of the apparatus is in a power saving mode. The synchronization comprises at least a coarse time synchronization and a coarse frequency synchronization.

Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.
