  • Patent number: 10701268
    Abstract: A technique is described herein for using an optical scanning system to visit points in a field along a scanning path. The scanning path includes consecutive passes, corresponding to time-shifted instances of a same scan pattern. The plural passes visit different sets of points within the field, to provide different respective sparse traversals of the field. When motion occurs, the passes evenly distribute the deleterious effects of motion over the field. This produces motion artifacts that resemble blur. The human eye and image processing systems can more effectively handle the presence of blur compared to the kind of motion artifacts produced by a traditional single-pass scanning operation.

  • Patent number: 10635922
    Abstract: A terminal for measuring at least one dimension of an object includes at least one imaging subsystem and an actuator. The at least one imaging subsystem includes an imaging optics assembly operable to focus an image onto an image sensor array. The imaging optics assembly has an optical axis. The actuator is operably connected to the at least one imaging subsystem for moving an angle of the optical axis relative to the terminal. The terminal is adapted to obtain first image data of the object and is operable to determine at least one of a height, a width, and a depth dimension of the object based on effecting the actuator to change the angle of the optical axis relative to the terminal to align the object in second image data with the object in the first image data, the second image data being different from the first image data.

  • Patent number: 10636391
    Abstract: A control device controls electronic labels in an electronic label system. The control device includes a first interface that acquires a captured image in which a commodity is included. A second interface transmits display information to an electronic label. A processor identifies, based on a captured image received via the first interface, the commodity and the position of the commodity. The processor determines a display position on an electronic label for displaying commodity information relating to the commodity based on the position of the commodity, and generates display information including the display position and a display content based on the identified commodity and the display position. The processor transmits the generated display information to the electronic label via the second interface.

  • Patent number: 10621954
    Abstract: Disclosed are systems and methods for improving interactions with and between computers in content searching, generating, hosting and/or providing systems supported by or configured with personal computing devices, servers and/or platforms. The systems interact to identify and retrieve data within or across platforms, which can be used to improve the quality of data used in processing interactions between or among processors in such systems. The disclosed systems and methods provide systems and methods for automatically filtering a compressed media file for perceptual display of the media content in a modified, higher-resolution format. The disclosed systems and methods apply novel visual filtering techniques to a compressed media file that enable the display of the rendered media content to appear to be displayed as a modified, higher-resolution version of itself without actually modifying the compressed media file during rendering.

  • Patent number: 10608673
    Abstract: Devices and methods described herein decode a sequence of coded symbols by guessing noise. In various embodiments, noise sequences are ordered, either during system initialization or on a periodic basis. Then, determining a codeword includes iteratively guessing a new noise sequence, removing its effect from received data symbols (e.g. by subtracting or using some other method of operational inversion), and checking whether the resulting data are a codeword using a codebook membership function. This process is deterministic, has bounded complexity, asymptotically achieves channel capacity as in convolutional codes, but has the decoding speed of a block code. In some embodiments, the decoder tests a bounded number of noise sequences, abandoning the search and declaring an erasure after these sequences are exhausted. Abandonment decoding nevertheless approximates maximum likelihood decoding within a tolerable bound and achieves channel capacity when the abandonment threshold is chosen appropriately.

  • Patent number: 10607047
    Abstract: Embodiments related to local tone mapping for symbol reading. A local pixel neighborhood metric is determined for at least one raw pixel in a region-of-interest, which identifies on one or more raw pixels near the at least one raw pixel. A local mapping function is determined for the at least one raw pixel that maps the value of the raw pixel to a mapped pixel value with a mapped bit depth that is smaller than the bit depth associated with the raw image. The local mapping function is based on a value of at least one other raw pixel near the at least one raw pixel within the local pixel neighborhood metric, and at least one parameter determined based on the raw image. A mapped image is computed for the region-of-interest by applying the local mapping function to the raw image.
