  • 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.

  • 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.

  • 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.

  • Patent number: 10157303
    Abstract: Systems and methods for product reader control are described. In various aspects, the product reader control is enhanced with image sensor(s) for steering product reader(s) to determine product attributes associated with scanned products. The product reader control system and methods may capture, with the image sensor(s), one or more images associated with a product. The product may have a product identifier and the product may be located within an onsite venue. Based on the detection of the product identifier in the image(s), a first product reader may be steered in a direction of the product, where the first product reader is located within the onsite venue with the product. The first product reader may scan the product such that the scanning determines at least one attribute associated with the product.

  • Patent number: 10140257
    Abstract: A mobile device captures information from a document. The mobile device selects a template stored in a memory of the mobile device. The selected template describes data content of at least one document. The mobile device then captures an image of a document, determines that the image corresponds to one document described by the selected template by verifying that at least one first region in the image corresponds to a region of the document described by the selected template, identifies at least one region in the image that corresponds with a region in the document described by the selected template, and processes information in the identified region in the image. The mobile device then aggregates application specific information from the processed information and presents the aggregated application specific information to a user program operating on the mobile device.

  • Patent number: 10142798
    Abstract: Ultrasonic transmitters periodically transmit ranging signals at unknown transmit timer values, and an ultrasonic receiver receives the ranging signals at known receive timer values on a mobile device in a venue in which a time difference of arrival (TDOA)-based ultrasonic locationing system is deployed. A controller infers the transmit timer values, and determines a current, real-time position of the mobile device based on flight time differences between the transmit timer values inferred by the controller and the known receive timer values.

  • Patent number: 10140725
    Abstract: Dimensions of an object associated with an electro-optically readable code are estimated by aiming a handheld device at a scene containing the object supported on a base surface. A scanner on the device scans the scene over a field of view to obtain a position of a reference point of the code associated with the object, and reads the code. A dimensioning sensor on the device captures a three-dimensional (3D) point cloud of data points of the scene in automatic response to the reading of the code. A controller clusters the point cloud into data clusters, locates the reference point of the code in one of the data clusters, extracts from the point cloud the data points of the one data cluster belonging to the object, and processes the extracted data points belonging to the object to estimate the dimensions of the object.

  • 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. The processor may determine a RFID tag event based upon the static analytic information and the active analytic information.

  • Patent number: 10142531
    Abstract: An imaging sensor of an imaging reader senses return light from a target to be read by image capture along an imaging axis over a field of view that extends along mutually orthogonal, horizontal and vertical axes. Two aiming light assemblies are offset from the sensor, and direct an aiming light pattern at the target. The pattern has an aiming mark in a central area of the pattern, and a pair of aiming light lines that are collinear along the horizontal axis. The visibility of the aiming mark is enhanced by optically configuring the aiming mark to be different in brightness and/or color and/or size and/or state of existence relative to a remaining area of the pattern. The aiming mark of enhanced visibility constitutes a prominent visual indicator of a center zone of the field of view.
