  • Publication number: 20120293319
    Abstract: A third brake lighting system for indicating the application of brakes in a vehicle comprising: a panic illumination portion, where the panic illumination indicates an urgent depression of the brakes by a driver of the vehicle; and a conventional illumination portion, where the convention illumination portion abuts the panic illumination portion and said conventional illumination indicates a non-urgent depression of the brakes by the driver. The present invention essentially provides mechanisms to indicate an urgent depression of the brakes by a driver of the vehicle; and mechanisms to indicate a non-urgent depression of the brakes by the driver of the vehicle.

  • Patent number: 6321990
    Abstract: Various optical components of an electro-optical system for reading coded indicia are mounted on a chassis snap-mounted in a housing. The optical components are supported by the chassis at an elevation relative to a printed circuit board snap-mounted to the chassis. The optical components are automatically adjusted in a test fixture.

  • Patent number: 6036094
    Abstract: A lightweight, easy to grasp and manipulate hand-held optical scanning device for scanning and digitizing image data from a two-dimensional bar code symbol for subsequent decoding in a personal computer platform. The scanning device achieves a small footprint in the user's workspace by utilizing a non-folded, substantially vertical optical path extending from an image viewing area upwardly to a linear charge-coupled device (CCD) array upon which the successive rows of the target two-dimensional bar code symbol are imaged. The scanning device is easily aligned with the symbol by placing it behind the symbol, and scanning of the successive rows of the symbol is accomplished by swiping or rolling the scanning device towards the user. Mechanical rollers on the underside of the scanning device provide translation information for use in clocking data out of the linear CCD array in order to scan the successive rows of the two-dimensional bar code symbol.

  • Patent number: 5920059
    Abstract: An interface between a two-dimensional bar code scanner and a host digital decoder is provided through a 15-pin electronic connector, which transfers to the decoder an actuating signal either from a scanner trigger switch or from an external device. In response, the digital decoder provides the scanner with operating power. The scanner generates and relays a bar code signal and a scanning direction signal back to the digital decoder, which uses these signals to identify a bar code being scanned as a one-dimensional or two-dimensional code. If the bar code is determined to be a two-dimensional code, upon detection of laser pattern alignment with the label the digital decoder sends a scanning control signal to the scanner to control a laser pattern generated by the scanner.

  • Patent number: 5837986
    Abstract: A microprocessor-controlled device with software files stored in non-volatile memory which can be easily modified by the user by reading or scanning a two-dimensional bar code symbol having program modification information encoded thereon. The symbol can be read by two-dimensional or one-dimensional laser or CCD based means. Depending on its size, either the entire file can be replaced, selected locations can be replaced, or selected relocatable object files can be linked at the target device in order to effect the program revision.

  • Patent number: 5818026
    Abstract: A system and method for capturing hand-marked cells from a lottery selection slip. The lottery slip includes a conventional play region of cells (labelled sequentially from 1 to 49, for example) for receiving indicia to be captured, after receiving indicia said play region of cells includes a plurality of occupied cells defined by marked cells and a plurality of non-occupied cells defined by unmarked cells. The lottery slip also includes row-identifier bar codes located at opposite boundaries of the play region. The bar codes are electro-optically scannable and readable and are arranged in a plurality of ordered rows tiered along the transverse direction over the transverse distance of the play region.
