Title: Digital signal processor
Inventor: MATSUI SHIGERU
IPC: H04L1/00
Filed: 1990-09-07
Abstract: PURPOSE:To prevent the generation of abnormal sounds by latching identifying signals which are discriminated to have no error by an error detecting means in a prescribed period, comparing them with the identifying signals which are newly discriminated to have no error, and suppressing the rapid change of inputted digital signals when the coincidence of both of them is not shown. CONSTITUTION:An identifying signal detecting means 4 detects the identifying signals included in the inputted digital signals, which detects the inputted digital signals. An error detecting means 5 detects the errors of the identifying signals detected by the identifying signal detecting means 4. An identifying signal latching means 6 latches the identifying signals which are discriminated to have no error in the prescribed period. Then, a coincidence detecting means 7 compares the identifying signals which are newly discriminated to have no error by the error detecting means 5 with the identifying signals of the identifying signal latching means 6, and detects the coincidence of both of them. A suppressing means 16 suppresses the rapid change of the inputted digital signals when the detected result of the coincidence detecting means 7 doesn't show the coincidence between both of them. Thus, the generation of abnormal sounds can be prevented by immediately performing the mute of the inputted digital signals after the change of the identifying signals are detected.

Filed: 1983-12-19
Abstract: PURPOSE:To make it possible to observe the image of drive data without moving a viewpoint to reduce the driver's fatigue, by providing an adjusting means for adjusting the distance between a lens system and a drive data indication source. CONSTITUTION:A reflected display image 28 is a virtual image which is created by a Fresnel lens 25 and is observed through a front windshield pane, and when a rotary knob 23 is rotated, the distance between the lens 25 and a liquid-crystal display panel 29 is changed. The position of image formation of the display image 28 varies in dependence upon the distance between the panel 29 and the lenst 25 so that the distance between the driver's eye E and the display image 28 is changed. When the knob 23 is slightly moved, the lens 25 moves to change the distance thereof with respect to the panel 29, and therefore, the position of image formation may be changed in accordance with individual differences in sight and the running condition of the vehicle. Since the image of drive data to be displayed may be formed and displayed far away and may be observed without moving a view point so that the driver's fatigue may be reduced.
