Abstract:

Various gun sights and related methods are provided. In one embodiment, a gun sight includes a light source adapted to project light, a user-viewable interface, and an optical element. The optical element includes a first surface adapted to pass the light to provide a reticle at the user-viewable interface. The optical element also includes a second surface adapted to refract the light to provide a light guide at a peripheral area of the user-viewable interface to aid a user to substantially align the user's eye with the reticle. Various mechanisms for aligning gun sights, attaching gun sights, related methods, and other embodiments are also provided.

Abstract:

The present disclosure includes programmable snubber circuits and methods. In one embodiment, a circuit is configured between first and second power supply terminals. A programmable snubber circuit may be configured between the first and second power supplies to reduce ringing on the power supplies. In one embodiment, the circuit is a switching regulator and the power supply terminals are internal power supply terminals. The snubber circuit may be programmed to reduce ringing caused by switching currents through parasitic inductances in a package.
