    摘要： A method and apparatus are provided for controlling the operation of a Laser Projection Display (LPD). Generally, the LPD is comprised of a laser, an optical system and a controller. The laser is adapted to emit a beam of laser light. The optical system is adapted to scan the beam of laser light on a display surface in a two-dimensional raster pattern. The controller is adapted to control the rate at which the laser beam is scanned to produce regions of varying resolution on the display surface. The controller is also adapted to present laser light onto the display surface within only selected portions of the two-dimensional raster scan pattern so that spaced apart image regions may be created.

    摘要： An optical code reader is provided including imaging circuitry having an array of photo sensing devices capable of sensing light incident on the array and outputting a plurality of pixel signals corresponding to the sensed light. The reader further includes control and logic circuitry for receiving a subset of the plurality of pixel signals, processing the received subset of the plurality of pixel signals for determining if the received pixel signals meet at least one predetermined condition, and outputting a selection control signal in accordance with the processing results. A focus analysis software module executable by the control and logic circuitry determines the focus quality of the received pixel signals. A selector control software module executable by the control and logic circuitry generates a selection control signal in accordance with the determined focus quality of the received pixel signals. Selector circuitry selectively enables the imaging circuitry to output selected pixel signals of the plurality of pixel signals in accordance with the selection control signal.

    摘要： An alignment indication is provided in an optical scanner for reading a two-dimensional optical code by varying the scanning beam to provide a region of apparent greater brightness. In the case of a PDF417 bar code symbol, an elongated brighter region may be oriented so that it is parallel with rows of the PDF417 symbol. The apparent greater brightness may result because of the persistence of the scanning pattern in the user's vision. The region of apparent greater brightness may be achieved by providing a greater density of scan lines in the region. Because of the persistence in the user's vision, multiple scan lines appear simultaneously, and thus a region with a greater density of scan lines appears as a brighter region. The region of apparent greater brightness may also be achieved by providing a differently shaped scanning spot in the region (e.g., a larger, or more elongated spot). Greater scan line density and differently shaped scanning spot may be combined to produce the region of apparent greater brightness.

    摘要： A bar code reader has an integrated scanning component module which is mountable on a printed circuit board. In one embodiment, the module may include the digitizer/decoder electronics, enabling the module to be used with a generic PCB. In some embodiments, the module includes a high speed optical scanning arrangement having an optical element which extends longitudinally of a flexible member, secured at one end. In other embodiments, the invention extends to a hand-held optical scanner having a scanning assembly, detector and data transmission coupling all mounted to a common printed circuit board, preferably located within a manually-graspable handle. In yet a further embodiment, an abuse-detector or accelerometer is provided for determining when the device is exposed to deceleration above a predetermined limit, and optionally for automatically shutting down applications programs and for providing a black-box-record of a short time frame before the device was exposed to an unexpected shock. Preferably, the reader is shock protected by a thermo-plastic elastomer housing section. An outgoing light beam is directed at a non-orthogonal angle relative to the PCB.
