Title: System for optimizing data length of data packet
Inventor: ARAI KAZUNARI
IPC: H04L1/00
Filed: 1988-02-12
Abstract: PURPOSE:To maximize data transfer efficiency by deciding the data length of an optimum data packet depending a data error rate measured by a data loopback by a diagnostic section so as to apply error control. CONSTITUTION:Diagnostic sections 4a, 4b measure an error rate to decide the length of the optimum data part, thereby obtaining the maximum data transfer efficiency. The data error rate is measured by the diagnostic sections 4a, 4b just before the data communication is started to decide the data length of the data packet and the data communication is applied by the data length. When the number of times of retransmission of the data packet is increased, the error rate is measured again by the diagnostic sections 4a, 4b to correct the data length to the optimum value. Thus, the efficiency of data transmission is maximized.

Title: Circuit for detecting target for sliding window
Inventor: FUJINO KENICHI
IPC: G01S7/32
Filed: 1989-02-09
Abstract: PURPOSE:To make it possible to separate and identify two close targets by separately providing a front-edge detecting sliding window SW and a rear-edge detecting SW, and setting the size of the rear-edge detecting SW so that the size is smaller than the size of the front-edge detecting SW. CONSTITUTION:A quantized video (a) from a quantized video memory 1 is sent into a front-edge counter 2 and a rear edge counter 3. A front-edge detecting SW size WLE is inputted into the counter 2, and a rear-edge detecting SW size WTE is inputted into the counter 3. When the front-edge detecting SW reaches a position P12, the front edge of a first target (b) is detected. When said SW reaches a position P14, the front edge of a second target (c) is detected. Meanwhile, when the rear-edge detecting SW reaches a position P13, a target count becomes equal to a rear-edge detecting reference value KTE in a window, and the rear-edge detected signal (e) of the first target is outputted. At this time, since the size WTE is smaller than the size WLE, the video of the front edge part of the second target does not enter into the window, and the identification of the rear edge of the first target is not hindered. When the rear-edge detecting SW reaches a position P15, the rear edge of the second target is detected, and the two targets can be separated and identified.
