Abstract: A method and circuit for finding the beginning of valid coded information from a scanner reading a label such as the Universal Product Code (UPC) label establishes a plurality of counting gates based on a predetermined sequence of discrete signal transitions and counts a plurality of related pulse frequencies during the gating periods under control of the established counting gates. The accumulated counts are compared in a predetermined sequence to determine whether selected counts when compared bear a predetermined relationship to each other and a code generated indicative of the relationship which indicates the beginning of valid label data or invalid label data on a continuous basis.

Abstract: A printer is disclosed in which a character forming print head is disposed on a carriage which pivots about a central point to describe an arcuate path, adjacent to which is situated an arcuate platen. The media to be marked upon conforms to the arcuate shape of the platen. The print head oscillates or reciprocates from one end of the arc to the other, and back. The arcuate path length may be varied to encompass printing in one or more coplanar stations on an arc in the plane of the print head and pivot.

Abstract: An electronic equipment drawer is aligned with an electrical connector in a tunnel in the horizontal and vertical directions with alignment pins and holes. A screw drive and cam mounted on the drawer engages a tunnel wall and controls insertion into the tunnel to provide proper electrical contact and lock the drawer in place in the tunnel. A bus extender card inserted in a connector centrally located on a mother board is supported by surfaces on a bar extending between end walls of the drawer. The end walls include pairs of channels on opposed walls which support feature cards inserted into connectors mounted on the bus extender card.

Abstract: A circuit for filtering positive and negative glitches (i.e., dropouts and noise spikes) in a pulse-like signal to be processed, utilizes a single timing element which introduces a uniform delay in both the leading and trailing edges of the pulse-like signal, thus eliminating pulse-width distortion of the signal. A single adjustment may be made which has the same effect on both the leading and trailing edges making a uniform adjustment of both delays easily achieved.

Abstract: A wand suitable for scanning the universal product code (UPC) symbol uses a light emitting diode for illuminating the symbol and a silicon photodetector for receiving the reflected energy. A single optical fiber is coupled to the diode and to a portion of a second single fiber for conducting narrow bandwidth visible light centered about 6,500 A to the terminus of the wand. The reflected light energy from the symbol when it is scanned by the wand is transmitted to the silicon photodetector via the said second single fiber which is also coupled to a third single fiber which conducts the reflected light energy to the silicon detector.
