Optical ballistic shield

This invention provides a system and method that is used to detect gunfire or explosions in an area with a sound system such as a movie, stage or theater setting, by differentiating the sounds in the presentation from those occurring in the physical location and automatically alerting authorities of the event in the movie or stage theater setting.

Event detection system and method of use

A method of making vertical diodes and transistors in SiC is provided. The method according to the invention uses a mask (e.g., a mask that has been previously used for etching features into the device) for selective epitaxial growth or selective ion implantation. In this manner, the gate and base regions of static induction transistors and bipolar junction transistors can be formed in a self-aligned process. A method of making planar diodes and planar edge termination structures (e.g., guard rings) is also provided.
