  • Imaging module and reader for, and method of, expeditiously setting imaging parameters of imagers for imaging targets to be read over a range of working distances
    Patent number: 10244180
    Abstract: An imaging reader has near and far imagers for imaging illuminated targets to be read over a range of working distances. A range finder determines a distance to a target. A default imager captures a minor portion of an image of the target, and rapidly determines its light intensity level. At least one of the imagers is selected based on the determined distance and/or the determined light intensity level. The exposure and/or gain of the selected imager is set to a predetermined value, and an illumination level is determined, also based on the determined light intensity level and/or the determined distance. The selected imager, which has been set with the predetermined value, captures an image of the target, which has been illuminated at the illumination light level.

  • Systems and methods for extrinsic calibration of a plurality of sensors
    Patent number: 10198829
    Abstract: Image processing systems and methods are provided for extrinsic calibration of a plurality of image sensors. A logic circuit receives image data for an omnidirectional object from image sensors spaced apart and imaging at least a portion of a region of interest. The logic circuit combines the image data from the image sensors to generate a calibration matrix for the image sensors and to determine a matrix transformation data based on (i) reference image data and (ii) a three-dimensional model of the reference object. The logic circuit modifies the calibration matrix into an enhanced calibration matrix by applying the matrix transformation data to the calibration matrix, where the enhanced calibration matrix can be used to calibrate the plurality of image sensors.

  • System and method for energy management within a group of devices
    Patent number: 10170920
    Abstract: Each charging member in a group identifies a docking connection. Each charging member, responsive to identifying the docking connection, transmits information to other charging members in the group and receives information transmitted from another charging member in the group. Each charging member generates a list using the information transmitted to the group and received from the group. Each charging member also includes a ranking component for filtering, sorting, and ranking entries in the list according to a predefined selection filter and/or ranking filter. Each entry in the list is associated with a charging member with a docking connection and in the group. Each charging member determines based on a predefined indication filter that an entry in the list that is associated with the charging member is ranked at a predefined position in the list and provides an indication.

  • Low profile, antenna array for an RFID reader and method of making same
    Patent number: 10158178
    Abstract: An antenna array, especially for use with a radio frequency identification reader, includes a ground plane and a pair of concentric, first and second, circular elements mounted at an elevation relative to the ground plane. First ports are arranged along the perimeter of the first element, and second ports are arranged along the perimeter of the second element. Each port conveys radio frequency signals in an operating band of frequencies. Each perimeter is substantially equal to an odd multiple of one-half of a guided wavelength at a center frequency of the respective operating band. Each adjacent pair of first ports, or adjacent pair of second ports, is successively spaced apart by a spacing constituting a whole multiple of one-half of the guided wavelength at the center frequency of the respective operating band. A polarized patch antenna may be positioned within the circular elements.

  • Systems and methods for point-of-sale detection with image sensors for identifying new radio frequency identification (RFID) tag events within a vicinity of an RFID reader
    Patent number: 10140486
    Abstract: Systems and methods for identifying new radio frequency identification (RFID) tag events within a particular vicinity of an RFID reader are described. In various aspects, a processor causes image sensors to capture a first set and a second set of video images, where the first set depicts a first RFID tag environment and the second set depicts a second RFID tag environment. The first RFID tag environment is static without a person moving within the first RFID tag environment and the second RFID tag environment is active with at least one person moving within the second RFID tag environment. An environment database may be generated and updated with static analytic information and active analytic information based on the first set and second set of video images, respectively.
