Title: Display device drive method and drive equipment
Inventor: ERIC PETER VANK
IPC: H04N5/44
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To make the occurrence of artifact just a little by adding noise to a video signal before the video signal receives a dithering operation. SOLUTION: A television signal is captured by an antenna A and is converted by a tuner TUN into the base band video signal. Various kinds of the video signal processing operations are received by a video signal processor VSP in order to afford the first video signal. When a switch SW selects one of these video signals, the selected signal is subjected to gamma correction by a gamma correction circuit γ. The noise signal generated by a noise generator NG is added to the output signal of the gamma correction circuit γ by an adder AD. The output signal of the adder AD is added to an A/D converter A/D having, for example, 8-bit output and thereafter, the signal is subjected to the dithering operation by a dithering circuit DC. The output signal of the dithering circuit DC is displayed on a plasma display panel PDP.

Title: Glass breakage detector
Inventor: ARIMA YOSHIO
IPC: G08B13/04
Filed: 1989-06-30
Abstract: PURPOSE:To highly sensitively detect the breakage of a large number of sheets of glass without increasing quantity of wiring by switching successively the both-end voltage of plural resistors connected to a constant-current power circuit in parallel to detect the both-end voltages. CONSTITUTION:To the constant-current power circuit 4, n-pieces of the resitors 2-1 to 2-n are connected in parallel through n-pieces of the switches S1 to Sn of a multiplexer, etc., to be switched ON/OFF automatically by turns. Since a constant current flows in every one piece of the resistors 2-1 to 2-n for prescribed time, and voltage change at that time is detected by one set of a detection circuit 6, resistance is reduced by 1/n compared with a case where n-pieces of this resistor are connected in series, and a current value is increased by n-times. Thus, detecting sensitivity can be raised, and simultaneously, the quantity of wiring can be reduced.
