Title: Optical repeater off-state supervisory method and device
Inventor: KIKAWA KATSUMI
IPC: H04B10/03
Filed: 1991-07-12
Abstract: An optical repeater comprising a photoelectric converter 1 which derives an electrical signal from an optical input, the value of which is monitored. The absence of an optical input is determined by the input OFF-state detection unit 7. In the event that an OFF-state is detected, the monitored electrical signal is then set to a fixed value, below that expected when receiving a minimum optical signal. The monitored signal is then converted back into an optical signal by the discrimination cct. 4 and the electro-photo conversion unit 5. This effectively reduces repeater errors associated with typical photo-electric converters such as the Avalanche photodiode. <IMAGE>

Title: High resolution parts handling system
Inventor: DEAN ARTHUR L
IPC: G06K9/46
Filed: 1991-09-16
Abstract: A high resolution article handling system serves as an article discriminator or identifier by creating an object silhouette. The objects are singulated on a conveyor and scanned by a linear array of CCD units 34 (2048 pixels per inch) at a scan rate of 10 MHz. Pixel transitions corresponding to object edge points are converted to a single count value from a counter 35 which is synchronized with the scanner. A microprocessor 54 with a first in, first out buffer memory 52 needs only a capacity to handle the count values rather than all data from the pixels. Article orientation is corrected in response to signal generated by determining the count value difference between a reference value and a work article value at only the scan slice windows at positions along the article length where differences have been predetermined to be a maximum for different article orientations. <IMAGE>
