Title: Time switch
Inventor: ITO KAZUHIKO
IPC: H04Q11/04
Filed: 1987-03-27
Abstract: PURPOSE:To increase the bit rate of a link up to the operating speed limit of a memory by writing data at the speed of the incoming link and reading the data at a speed of an outgoing link in case of readout in writing the data to a channel memory provided to each link to increase the bit rate of the link up to the limit of the operating speed of the memory. CONSTITUTION:When data of incoming links 1-n is written in channels M1-Mn the channel memories M1-Mn are provided to the links 1-n correspondingly and the data is written at the same speed as the bit rate of the incoming links 1-n. Moreover, when the data in the memories 1-n is read, the data is read sequentially from a selector 1 according to channel memory selection information outputted from a 2nd storage memory 3 and given to an outgoing link. Since the selector 1 has only to output the data to its own link only, the read speed is the same as the bit rate of the outgoing link. Thus, even if the number of links is increased, only the channel memory corresponding to the link is increased and the write/read speed remains same principally.

IPC: G06T1/00
Filed: 1990-03-26
Abstract: PURPOSE:To attain safely the autonomous traveling of a vehicle by correcting the result of recognition of an outside recognizing means so as to dissolve the difference between the estimated result of recognition and the actual one of an outside recognizing means and therefore compensating a steady recognizing error if produced by the outside recognizing means. CONSTITUTION:A variance detecting part 21 processes first a signal S1 and obtains the variance of a steering angle mu at each constant time TO for a prescribed period of time together with the average mu and the dispersion sigma<2>mu of the variance. At the same time, a signal S2 is processed so that the variance of a distance (x) is obtained for a prescribed time together with the average (x) and the dispersion sigma<2>X. An error estimating part 22 obtains the estimated result of recognition of an outside recognizing part 12, i.e., a distance X between a disappearing point T and an image center line C from the steering angle average together with a difference DELTAx = X - x between the distance X and the average (x). A correction means 23 corrects the local map information K inputted to an optimum route deciding means 14 in order to dissolve the stored recognition error DELTAx. Thus an optimum route is correctly decided in accordance with the actual external environment.
