  • Publication number: 20100158055
    Abstract: A method of monitoring the output power of a laser diode in a barcode reader. The method includes sampling a threshold monitoring-current that is related the driving-current passing through the laser diode during a first time period when this current is at the lasing threshold of the laser diode. The method includes generating a threshold-compensated monitoring-current by subtracting the threshold monitoring-current from the above-threshold monitoring-current. The method includes monitoring the output power of the laser diode in the barcode reader at least partially based on the threshold-compensated monitoring-current.

  • Patent number: 7742456
    Abstract: Described is a method for locationing in a communications network. A wireless access point receives a signal corresponding to activity of a plurality of wireless devices on a predetermined bandwidth. The signal is processed to generate a plurality of subsignals using a predetermined signal processing procedure. An energy level of a particular subsignal of the plurality of subsignals is determined. A location of a corresponding wireless device is determined as a function of the energy level and a predetermined locationing procedure.

  • Patent number: 7742348
    Abstract: Methods and systems are provided for improved protection of radio frequency identification tag memory by using two or more “brownout-safe” pointer registers (instead of a single pointer register) that are logically concatenated to form a complete address for the boundary between a locked portion and an unlocked portion of the tag memory. A first pointer is a coarse pointer identifying a block of memory containing the boundary. A second pointer is a fine pointer identifying a specific location within the identified coarse block of memory. The coarse pointer may be a gray-coded or linear pointer. Similarly, the fine pointer may be a gray-coded or linear pointer.

  • Patent number: 7742649
    Abstract: An image compression system and method is described, which makes use of the symmetry found in faces and heads to perform the compression. The image is divided along the line of symmetry, and pairs of corresponding pixels on the two divided sides are determined. A weighted average and a weighted variance of the pixel values of the pairs is computed, and is used to encode the image. A transform such as the Karhunen-Loeve transform is used to compute the weighted averages and variances.

  • Publication number: 20100147953
    Abstract: The present disclosure concerns a bar code reader 10 that can both interpret bar codes and image documents. The bar code reader includes a housing including a vertical and a horizontal transparent window H, V and defining a housing interior region. As a target object is swiped or presented in relation to the transparent windows an image of the target object is captured. Cameras C1-C6 have image capture sensor arrays positioned within the housing interior region for capturing an image of an object within a camera field of view. Two specific cameras can capture the front and back images from a document such as a check 100 placed on the horizontal transparent window.
