Abstract: An integrated circuit device having a television signal tuner, video decoder and power control circuit. The television signal tuner selects one of a plurality of television channels, and the video decoder converts a television signal conveyed in the selected television channel into a video display signal. The power control circuit alternately enables and disables the television tuner to enable reception of a first portion of video information conveyed in the television signal and to disable reception of a second portion of the video information.

Abstract: An angular rate sensor made from a structural wafer of single crystal silicon has a pair of proof masses lying in an X-Y plane and supported by a circular frame. The masses are driven into oscillation in the X-direction using an interdigitated comb drive. Rotation of the sensor about the Z-axis induces Coriolis forces which cause the frame to rotate, the rotation of the frame being indicative of the angular rate of the sensor. A parallel plate sensor located outside of the circular frame senses rotation of the frame.

Abstract: Methods for surface micro-machining silicon wafers, including coating cavity sidewalls with oxidation-resistant material to prevent lateral oxidation. This in turn prevents "bird's beak" during formation of a diaphragm. The methods are useful for, among other things, the manufacture of absolute-type pressure sensors. Along with bulk micro-machining techniques, the methods can be used to produce gauge- and differential-type pressure sensors, as well.
