High density electrical connector with variable insertion and retention force

An interconnection system that includes a daughter card and backplane electrical connectors mounted to printed circuit boards at connector footprints. The spring rate of beam-shaped contacts in the daughter card connector increases while mating with the backplane connector so that the retention force may be greater than the insertion force. Such a change in spring rate may be achieved by positioning the beam-shaped contacts adjacent a surface of a connector housing. That surface may include a projection that aligns with the beam-shaped contact. When the connectors are unmated, the beam-shaped contact may be spaced from the projection. As the connectors begin to mate, a central portion of the beam-shaped contact may be pressed against the projection, which has the effect of shortening the beam length and increasing its stiffness.

Methods and apparatus for using imaging information to improve scanning accuracy in bar code scanners

Techniques for using imaging information computed from examining a scanner signal are described. When one or more objects passes within a field of view of a scanner, scan patterns emerging from one or more scanner windows and reflected from the objects back into the scanner windows produce one or more scanner signals. The scanner signals are processed to obtain beam position and beam length information to improve the accuracy of bar code decoding and to compute imaging information for objects within the field of view of the scanner. The imaging information for the objects is compared with bar code information for the objects. The expected number, size and shapes of objects indicated by the bar code information is compared with the actual number, size and shapes of objects in order to determine if valid scans occurred or if missed, double or otherwise erroneous scans occurred.
