  • Video format unit
    Patent number: 4467354
    Abstract: In high speed imaging systems wherein document images are lifted and stored, it is desirable to reduce the amount of information to be stored. A video format unit utilizing video information from a data lift enhances the video information and then compresses the enhanced video data by coding the data in a repetitive run length type code. The coded data is then stored in an on-line system to permit the immediate recall of stored images.

  • Barcode width measurement system
    Patent number: 4411016
    Abstract: A single columnar array of scanning diodes is used to make width measurements of bar codes in order to read the contents thereof. The bar code is scanned utilizing a scanning procedure which directs the columnar array along the bar code such that the photo elements on the scanning array lie along an axis parallel to a line drawn horizontally through the bar codes. The same scanning array may be used to read alphanumeric characters scanning along an axis perpendicular to the columnar array.

  • Wand turn-on control
    Patent number: RE30916
    Abstract: Disclosed is a control circuit used to conserve power in a portable optical recognition system. When the system is not being used or between actual scans of the reading electronics, power is supplied only to those circuits required to control power to the system and to permit sequence reading of items. An infrared signal is emitted from the reading device and when a document or other item to be read is scanned the infrared signal is reflected back into the scan unit and is detected, thereby sensing that a document is being read and turning the system on.
