Abstract:
A nitride based semiconductor laser diode device comprising a selective growth mask with a grating structure is proposed. The island-like stacked epitaxial layers including the P-type cladding layer is formed from the selective growth mask upon the active layer of the semiconductor laser structure. This proposed structure can reduce the strain by the deformation due to the isolate structure. Thus, increase of thickness of the cladding layer and/or increase of composition difference can be achieved without crack existing in the island-like stacked epitaxial layers. The optical confinement can be effectively improved.

Abstract:
A wireless communications device connected to a service network with a synchronized timing pattern therebetween is provided. In the wireless communications device, a wireless modem is configured to enable wireless signal transceiving from and to the service network in a non-sleep mode and disable wireless signal transceiving from and to the service network in a sleep mode. Also in the wireless communications device, a synchronization module is configured to initialize a first counter with a current time in the synchronized timing pattern in response to a first signal triggering the wireless modem to enter the sleep mode from the non-sleep mode, and enable counting of the first counter in a low-rate clock for the sleep mode. The synchronization module further provides the counted value of the first counter to the wireless modem to resynchronize with the service network in response to a second signal triggering the wireless modem to recover from the sleep mode to the non-sleep mode.

Abstract:
The disclosure relates to an apparatus to improve the performance of system logging. The apparatus comprises a buffer storing a log, a log register comprising a bit, and a core unit. The core unit is coupled to the buffer and the log register to acquire and transmit the log to an external computer host when detecting that the bit is asserted.
