Abstract: A differential self-locking device includes a differential housing, a half-shaft output gear set disposed in the differential housing, an upper worm and worm gear mechanism, a lower worm and worm gear mechanism, a differential planetary gear set, and a worm gear shaft. The upper worm and worm gear mechanism and the lower worm and worm gear mechanism respectively convert a large output torque of the left half-shaft output gear and a large output torque of the right half-shaft output gear into small output torque thereof to lock the left half-shaft output gear and the right half-shaft output gear, thereby achieving automatic locking or unlocking of the differential self-locking device. A traction force of a vehicle is converted into torques of the left half-shaft output gear and the right half-shaft output gear, which improves passing ability of the vehicle.

Abstract: An optical communication system includes a light source and an output capacitor coupled to the light source. The system also includes a switching converter circuit coupled to the output capacitor. The switching converter circuit is configured to provide an output voltage to the output capacitor based on an active mode and a power-save mode. The switching converter circuit includes a controller configured to perform pulse gating in the power-save mode based on a timer and a comparison of the output voltage with a voltage threshold.

Abstract: Examples to control timing for current-mode boost converters are disclosed. An example device to control timing includes a first input terminal to receive an input voltage of a current-mode boost converter a second input terminal to receive an output voltage of the current-mode boost converter, a generator to generate a first timing signal from the input voltage and the output voltage, a third input terminal to receive a second timing signal from the current-mode boost converter, a selector to select between the first on_off time signal and the second on_off time signal to generate a third on_off time signal based on a comparison of a first off time duration of the first on_off time signal and a second off time duration of the second on_off time signal, and an output terminal to control off times of the current-mode boost converter based on the third on_off time signal.

Abstract: The subject disclosure is directed towards executing jobs based on resource usage. When a plurality of jobs is received, one or more jobs are mapped to one or more other jobs based on which resources are fully utilized or overloaded. The utilization of these resources by the one or more jobs complements utilization of these resources by the one or more other jobs. The resources are partitioned at one or more servers in order to efficiently execute the one or more jobs and the one or more other jobs. The resources may be partitioned equally or proportionally based on the resource usage or priorities.
