  • High performance scan engine with rear-facing image sensor in handheld arrangement for, and method of, imaging targets using the scan engine
    Patent number: 8835825
    Abstract: An arrangement for, and a method of, electro-optically reading a target by image capture, employ a scan engine in a handheld housing having a tilted handle. A single tilted printed circuit board (PCB) in the handle has front and rear surfaces that respectively face toward and away from the target during reading. An optical assembly having a pair of fold mirrors is mounted on the rear surface, for receiving return light from the target through an aperture in the PCB along the horizontal, and for directing the return light along a folded path. An imaging lens assembly projects the return light onto a solid-state, two-dimensional, image sensor to enable the return light to be detected over a field of view, and to generate an electrical signal indicative of the detected return light.

  • APPARATUS FOR AND METHOD OF AUTOMATICALLY INTEGRATING AN AUXILIARY READER IN A POINT-OF-TRANSACTION SYSTEM HAVING A WORKSTATION READER
    Publication number: 20140252094
    Abstract: A checkout system for electro-optically reading targets includes a host, a workstation reader, and an auxiliary reader operatively connected to the workstation reader. The workstation reader captures data associated with the targets, and communicates its captured data with the host over a predetermined communications protocol. The auxiliary reader also captures data associated with the targets independently of the workstation reader. The workstation reader automatically integrates the auxiliary reader in the system by automatically detecting the protocol of the auxiliary reader, and by automatically configuring the detected protocol of the auxiliary reader to conform to the predetermined communications protocol of the workstation reader, thereby enabling the auxiliary reader to communicate its captured data with the host.

  • MITIGATING AUDIBLE CROSS TALK
    Publication number: 20140236589
    Abstract: Audible crosstalk can be mitigated in a low-cost three-wire device having audio capability and/or voice applications. In some embodiments, a voltage can be introduced in a microphone power supply that is approximately the same as a measured noise voltage and the resulting voltage appearing at a microphone output can be optimized to mitigate the noise voltage and, thus, the presence of crosstalk. In some embodiments, a microphone within a circuit can be isolated to mitigate crosstalk by introducing current into a circuit that is approximately the same as a measured current, but having a flow in an opposite direction.

    Abstract: A method and device for non-echo ultrasonic Doppler used for corrected inertial navigation includes providing at least one ultrasonic emitter within an environment, each emitter configured for transmitting an ultrasonic tone of a predefined frequency. An initial location of the mobile device is established within the environment. Dead reckoning procedures are initiated using sensors within the mobile device. The device receives at least one ultrasonic tone from an emitter, and converts the at least one ultrasonic tone into a digital waveform. The device determines at least one peak frequency of the digital waveform, and subtracts the at least one peak frequency from each predefined frequency to determine at least one Doppler shift, which is used for correcting the dead reckoning of the mobile device.

  • Imaging reader with non-uniform magnification within a field of view
    Patent number: 8777106
    Abstract: An imaging lens assembly captures return light through a window of a vertical slot scanner from a target located in a range of working distances along an optical axis away from the window, and projects the captured return light onto an array of a solid-state imager. The imaging lens assembly is optically modified for non-uniform magnification within, and for increasing resolution at an outer peripheral region of, a field of view of the array, in an imaging plane generally perpendicular to the optical axis. The magnification is at least partly increased in the imaging plane with increasing radial distance away from the optical axis, to enable reading of the target when tilted relative to the optical axis and located at the outer peripheral region of the field of view.
