Abstract:
The present invention discloses a switching regulator control circuit which distinguishes the output short-circuit condition, which imposes immediate danger, from other mild over current conditions. The switching regulator control circuit includes: an over current judgment circuit comparing a current sense signal with a current limit to generate an over current indication signal; a time comparison circuit comparing the over current indication signal with a clock signal to generate an output short-circuit indication signal; and a timer receiving the over current indication signal and the output short-circuit indication signal, wherein when the output short-circuit indication signal does not indicate output short-circuit, the timer counts a first time period, and when the output short-circuit indication signal indicates output short-circuit, the timer counts a second time period shorter than the first time period, for better safety protection.

Abstract:
A differential driving circuit for powering a light source is disclosed. The differential driving circuit includes a first set of switches and a second set of switches. A first current from a power source flows through the first set of switches to charge a first energy storage element when the first set of switches are turned on. A second current from the first energy storage element flows through the second set of switches to power the light source when the second set of switches are turned on. The differential driving circuit further includes a second energy storage element coupled to the light source in parallel and for providing a differential voltage to the light source.

The supporting member can rotate relative to the main body to form an included angle for supporting the electronic device.
Abstract:
An information distribution device performs a method for selectively distributing media associated with an incident to a plurality of responders assigned to the incident. The method includes receiving, at the information distribution device, an incident information bundle comprising media inputs associated with the incident. For each responder in the plurality of responders assigned to the incident, the information distribution device: determines a set of roles for the responder; selects a set of filtering templates designed based on the set of roles; applies the set of filtering templates to the information bundle to generate a responder information bundle that includes a subset of the media inputs that is customized to the set of roles for the responder; and delivers the responder information bundle to the responder.

Abstract:
A pixel structure of a transflective liquid crystal display panel. The pixel structure has single cell gap design, but a coupling capacitor and a modulating capacitor are properly connected to the reflection electrode so as to modulate the voltage of the reflection electrode. Consequently, the transmission region and reflection region of the pixel structure have substantially consistent gamma curves.
