Title: Syntax parser for video decompression processor
Inventor: KURISU FUUJIENBUUMU
IPC: H04N7/50
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To analyze information requested by various sub-systems from a bit stream, and advancing it to a proper sub-system for further processing. SOLUTION: A video compression processor 20 is provided with a video syntax purser 40. A compressed bit stream is checked until a starting code is searched. The starting code is decoded for inctiating a specific parser state corresponding to it. The parser state is transmitted to plural sub-systems 36, 42, 44, 46, 48, 52, 54, and 56 of the video de-compression processor 20. Each sub-system monitors the parser state for determining which analyzed data following the starting code are directed to the sub-system. Then, the sub-system retrieves necessary analyzed data through a data bus 58 for receiving analyzed data from the parser 40.

IPC: G01C19/5607
Filed: 1987-11-30
Abstract: PURPOSE:To drive a vibrator at a constant vibration speed irrespective of an angular velocity by driving a driving use piezoelectric element by a self-oscillation, and also, by an AC constant-current. CONSTITUTION:Four pieces of excitation vibration detecting use piezoelectric elements 5 are stuck to a vibrator 2 by allowing them to correspond to each driving use piezoelectric element 1, and a self-oscillating circuit for using an output voltage of this piezoelectric element 5 as a driving voltage of the piezoelectric element 1 is formed. By integrating a constant-current circuit 6 into this self-oscillating circuit, driving of the piezoelectric element 1 is executed by an AC constant current output whose current amplitude is constant. A supply voltage to the constant-current circuit 6 is a voltage which has been controlled and amplified so that the product of an excitation voltage whose higher harmonic component has been eliminated by an LPF 7 and a DC voltage which has been converted by a root mean square DC converter 8 becomes constant. In such a way, when the vibrator 2 is vibrated, even if an angular velocity is applied to a vibration gyro, a vibration speed of the vibrator 2 is not varied, but constant. As a result, a relation of the angular velocity and Corioli's force always holds a prescribed proportional relation, therefore, the angular velocity can be detected with high accuracy.
