    Abstract: A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edge of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.

    Abstract: A trigger-operated or triggerless scanner reads symbols with a first scan pattern in a first intended position of hand-held use. Either scanner may be mounted on a stand-alone fixture wherein the first scan pattern is converted to a second, different scan pattern, again for reading indicia in a second intended position of workstation use. Various signal processing digitizing circuits for faithful digital reconstruction of the symbols are disclosed.

    Abstract: An optical scanner (30) has a scanner component mounted to a leaf spring (34) for oscillatory motion about an axis. An electromagnetic coil (58) and permanent magnet (56) cause a force to be applied to the scanner component away from a central, neutral position. Bending of the leaf spring provides a restoring force biasing the scanner component back towards the neutral position.
