  • Patent number: 9507987
    Abstract: Interchangeable illumination modules having different optical characteristics illuminate a target to be electro-optically read by image capture. Each module includes an illuminating light source for emitting illuminating light, and a support for supporting the illuminating light source for joint movement as a discrete unit from a removed position away from a reader to a mounted position on the reader. The support is accessible exteriorly of the reader in the mounted position. Electrical contacts mounted on the support are exposed exteriorly of the support for supplying an illumination control signal from the reader to the illuminating light source to energize the illuminating light source in the mounted position.

  • Patent number: 7986340
    Abstract: A lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, is operative for causing selected pixels in a raster pattern of scan lines to be illuminated to produce an image of high resolution in color. The direction of scanning of the scan lines is switched between alternate frames, and the resulting image is the superposition of successive frames integrated for viewing by the human eye.

  • Patent number: 7891570
    Abstract: An arrangement for improving performance of a sensor operative for collecting light from a target to generate a data signal in a presence of ambient light, includes a sample and hold circuit for operating the sensor during a sampling time period in which the sensor only collects the ambient light to generate an ambient signal, and during a holding time period in which the sensor collects both the ambient light and the light from the target to generate a composite signal comprised of the ambient signal and the data signal; and a subtracting circuit operative for subtracting the ambient signal from the composite signal to produce the data signal as an output.

  • Publication number: 20100302420
    Abstract: A method and apparatus for reducing the visual discomfort of the illumination generated by imaging scanners. The method includes (1) turning on a driving current for a illumination source during each of a series of exposure periods to provide illumination directed toward a target object; (2) capturing an image from the target object with photosensitive circuitry during at least one of the exposure periods; and (3) generating a pulse-width-modulation driving current that has a duty cycle changing with time between two consecutive exposure periods for making perceived gradual illumination changes between the two consecutive exposure periods. The duty cycle decreases from the value of 100% to a minimal value after each of the exposure periods and increases from the minimal value to the value of 100% before each of the exposure periods.

  • Patent number: 7620432
    Abstract: The present invention relates to a mobile terminal that can interoperate with a plurality of headsets. The present invention further relates to systems and methodologies for facilitating communication to the mobile terminal from the plurality of headsets. The plurality of headsets can be of various types. For example, the headset can be a push button enabled signaling headset, which includes a signaling mechanism, such as a button, mounted to the headset or a headset cord. The mobile terminal includes a sensing component to detect the signaling from the headset. The signaling mechanism is employed to issue commands to the mobile terminal. Alternatively, the headset can be a standard, commercially available audio headset. If the standard headset is employed, the signaling function is not available and the standard headset operation is not impacted.

  • Patent number: 7512254
    Abstract: Described is a method and system for authenticating identity of a person using a portable device. The portable device may includes an imager, an image processing unit and a processor. The image processing unit reads encoded data in a first image from an imager of the device. The image processing unit extracts a portion of a second image from the imager to generate extracted portion data. The extracted portion of the second image corresponds to a portion of a person whose identity is to be authenticated. Stored biometric data for a person is located based on the data read from the first image. The processor compares the extracted portion data of the second image to the stored biometric data for a person.

  • Patent number: 7468508
    Abstract: A composite laser beam is swept as a pattern of scan lines on a projection surface, and selected pixels arranged along each scan line are illuminated to project an image of high quality and in color. A data frequency of a video signal supplied by a host is matched to a scan frequency of a scan mirror to reduce the amount of buffer memory required and to make the projected image brighter and more uniform in brightness.

  • Patent number: 7352499
    Abstract: A laser beam is swept by a scan mirror as a pattern of scan lines on a projection surface. The scan mirror moves at a variable speed along each scan line. Each scan line has a number of pixels. The pixels have time durations proportional to the variable speed of the scan mirror. A profile memory stores the time durations of the pixels. A controller causes selected pixels arranged along each scan line to be illuminated for the time durations stored by the profile memory to produce an image of uniform brightness and of uniformly sized pixels and in color.

  • Publication number: 20070279509
    Abstract: An acousto-optical modulator modulates a green laser beam, and generates a modulated non-diffracted beam and a modulated diffracted beam. A scanner sweeps the modulated diffracted green beam, as well as modulated red and blue beams, as a pattern of scan lines, each scan line having a number of pixels. A controller causes selected pixels along the scan lines to be illuminated, and rendered visible, by the diffracted green beam, the red beam and the blue beam to produce the image. The non-diffracted green beam is employed in a laser shut-down safety circuit.
