Abstract: Cash drawer system for a point-of-sale terminal having a housing, a latchable drawer, and a mechanism for forcing the drawer outward. The drawer slides on a pair of slides positioned beneath the drawer, and the drawer is latchable to the slides by latches located in the front of the drawer. Orienting features of the slide and drawer cooperate to orient the drawer for latching during drawer insertion. The drawer is also laterally movable on the slides, which prevents jamming, binding and racking of the drawer if the slides are in a non-parallel position. A central portion of the drawer may be lower than the edges to provide increased media space below a cash till.

Abstract: A vehicle guidance and control system has a number of trucks whose movement is controlled by a base station. Each truck periodically fixes its own position in relation to marker boards consisting of patterns of reflective coded stripes by scanning a narrow laser beam in a predetermined direction across the stripes. Using at least two boards its position can be determined by triangulation, and because the beam scans in a fixed direction, the positional accuracy can be determined by a particular stripe or edge of a stripe, and not by the size of a marker board as a whole.
