  • Optimizing RFID Reader Duty Cycle Or Power To Preserve Battery Life
    Publication number: 20090079571
    Abstract: The duty cycle of a portable battery-powered RFID tag reader is reduced during time periods when it is less likely to produce a “read” in order to preserve battery life. The reader operates with an aggressive duty cycle during periods of a high probability of a tag read and reduces duty cycle during periods of a low probability of a tag read. In this manner a user does not perceive the reader to be sluggish. An alternative embodiment reduces peak operating power during time periods when a tag is less likely to produce a “read” in order to preserve battery life.

  • Multiple Configuration Image Scanner
    Publication number: 20090078773
    Abstract: An imaging-based bar code reader that includes an imaging and decoding system. Focusing optics and a sensor array define a field of view. An exemplary system has an image sensor includes multiple configuration registers. With multiple configuration registers a video mode can be implemented where the video consists of a continuous sequence of frames with a fixed sequence a number of configurations. The configurations can vary the frame size, exposure time, gain, etc. Compared to a sensor with only one set of configuration registers, successive frames can be captured with different configurations without synchronization issues or frame lag.
