IPC: B60G7/00
Filed: 1984-04-11
Abstract: PURPOSE:To improve comfortability to drive by detecting the oscillation of a suspension arm and increasing the resistance to the forward and backward movements of a car body for the oscillation exceeding a set point. CONSTITUTION:The detection signal for the oscillation of a suspension arm is inputted to a control circuit 26 from a G sensor 20 and compared with a set point in an operation section.

IPC: H04N5/265
Filed: 1987-03-30
Abstract: PURPOSE:To obtain a smooth moving picture with high vertical resolution as to a moving pattern and to obtain a picture with fluctuation as to a still picture by switching a write address depending on the result of discrimination of a field discrimination circuit of a video input signal so as to control the read address by the result of comparison of the position of write/read patterns. CONSTITUTION:A write address is switched from the result of discrimination of a field of a video input signal to write video signals of both 1st and 2nd fields into separate areas of the memory. In case of readout, a write pattern position and a read pattern position are compared to discriminate the moving/ stilling pattern and the read address is switched for each field as to the moving pattern to output alternately the signals of both the fields and only the signal of the 1st field is outputted always to the still pattern. Thus, a picture is obtained for the moving pattern by using the signal of both the fields through interlacing and a field still picture is obtained as to the still pattern.
