  • Patent number: 7367510
    Abstract: An arrangement for determining light beam position in an electro-optical reader, image projector and like devices includes a drive for moving a scanning light beam at a scan frequency across a target as a scan line, and an electro-optical feedback assembly operatively connected to the drive, for optically detecting scan line position during beam movement, and for generating a feedback signal at the scan frequency, the feedback signal being indicative of the scan line position. A feedback coil in the drive is eliminated to avoid electromagnetic coupling between multiple coils in the drive.

  • Patent number: 7369584
    Abstract: 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.

  • Patent number: 7367499
    Abstract: Described is a multi-optic scanner that can detect and/or measure weight placed on its vertical plate. In one embodiment, a portion of the vertical plate is positioned under a portion of a horizontal plate so that a force exerted on the vertical plate is transferred, whole or in part, to the horizontal plate. In alternate embodiments, one or more sensors are coupled to the vertical plate for detecting a force on the plate. The sensors can be coupled to an alert, such as an audible signal, to warn an operator of a misread weight.

  • Publication number: 20080100447
    Abstract: Methods and apparatuses are described for reducing interference amongst frequency identification (RFID) readers operating within an interference range. Groups of frequencies from a range of frequencies are determined such that RFID readers transmitting on adjacent frequencies in a particular group of frequencies experience substantially negligible interference. A first group of frequencies is selected for a first time period of operation. RFID readers are each assigned a unique frequency from the first group of frequencies. At the end of the first time period, a second group of frequencies is selected and RFID readers are each assigned unique frequencies from the second group of frequencies. Substantially all frequencies of the groups of frequencies are assigned during a predetermined time duration.

  • Publication number: 20080104010
    Abstract: Methods, systems, and apparatuses for configuring a radio frequency identification (RFID) reader using an RFID tag are described. A RFID tag is read by the reader to obtain reader configuration information from the RFID tag. A registry of the reader is modified to include the reader configuration information. A management system is communicated with by the reader, based on information obtained by the reader in the reader configuration information. The reader is thereby configured for operation.

  • Publication number: 20080100439
    Abstract: Methods, systems, and apparatuses for ways of locating tags are described. A power level of a RFID communication signal transmitted by a RFID device, such as a reader, is adjusted to hone in on a specific tag. For example, the power level may be decreased or increased, depending on the situation, to hone in on the tag. The RFID device may be repositioned to aid in further honing in on the tag. Transmitting RFID communication signals, adjusting transmit power levels, and repositioning the RFID device may be iterated as needed to hone in on the tag.

  • Publication number: 20080100329
    Abstract: Methods, systems, and apparatuses for ways of testing tags are provided. In an aspect of the present invention, an antenna is mounted in a cavity of a surface. The antenna transmits a test signal, such as a radio frequency (RF) test signal, to the antenna of an adjacent tag, to test the adjacent tag. In aspects, multiple cavities having antennas may be arranged in various ways in the surface, such as in a “checkerboard pattern” (e.g., diagonally positioned from each other), to test multiple tags in a web of tags simultaneously. In another aspect, tags that are not being tested may be held at an electrical voltage, such as a ground voltage, to disable the tags from responding to the test signals of other tags. For example, in an aspect, a vacuum system may be used to hold tags in a web of tags to the surface to hold antennas of the tags at the electrical voltage.

  • Publication number: 20080100452
    Abstract: Methods and apparatuses for assembling and implementing optically machine readable radio frequency identification (RFID) tags are described. An RFID tag comprises a substrate, an electrical circuit mounted on the substrate, and an antenna that is configured to be machine readable. For example, the antenna may include a plurality of electrically conductive substantially rectangular bars formed on a first surface of the substrate. Bars of the plurality of electrically conductive substantially rectangular bars are positioned in parallel with each other and are configured to be an optically machine readable symbol. Bars of the plurality of electrically conductive substantially rectangular bars form at least one antenna. The electrical circuit is electrically coupled to the plurality of electrically conductive substantially rectangular bars. Alternatively, a plurality of patches are formed on the first surface of the substrate to form a two-dimensional optically machine readable symbol.

  • Patent number: 7364080
    Abstract: Described is a system and method for bar code detection. The method comprises generating a digitized bar pattern (DBP) including a series of elements corresponding to elements of a scanned bar code, and identifying a first set of margins around a first portion of the series of elements. When an attempt to decode the first portion is unsuccessful, the first portion is analyzed to determine a second set of margins around a second portion of the series of elements, the second set of margins being within the first set of margins, and the second portion is input to a decoding algorithm.

  • Patent number: 7364074
    Abstract: A method of identifying or authenticating a product by providing an analog identification indicium including a randomized pattern of identification features on a first part of the product wherein one or more attributes of the randomized pattern of identification features correspond to an item identifier. A digital identification record is provided on a second part of the product including an encoded digital version of the item identifier, the first and second parts being separable when the product is used. The randomized pattern of identification features of the analog identification indicium is read and decoded to generate an item identifier and the digital identification record is read and decoded to generate an item identifier. The product is deemed authentic if the item identifier from the analog identification indicium substantially matches the item identifier from the digital identification record.

  • Patent number: 7363051
    Abstract: A dual mode mobile unit is arranged to communicate in either a first or second data communications standard, such as combined Bluetooth and 802.11 operation. An interface unit converts received Bluetooth or 802.11 format signals into 802.11 frame format data signals to be provided to a digital signal processor which is programmed to process signals in either standard. The dual mode mobile unit can operate in the 802.11 standard to reserve a time interval for Bluetooth activity during which other 802.11 units will avoid transmissions to avoid interference.
