  • Publication number: 20230422380
    Abstract: Various embodiments described herein provide implementations for controlling flicker, for example caused by a plurality of light sources, in a multi-sensor environment. Various embodiments provided utilize a broadest illuminator source for capturing image data objects for processing. The broadest illuminator source minimizes the number of activation changes required between the various illuminator sources. One example embodiment includes activating a broadest illuminator source of a plurality of illuminator sources; determining, based on a plurality of image sensors and an sensor activation sequence, a chosen image sensor of the plurality of image sensors for an image processing operation; and activating a chosen illuminator source of the plurality of illuminator sources, the chosen illuminator source associated with the chosen image sensor.

  • Publication number: 20230345130
    Abstract: Embodiments of the disclosure relate generally to flicker reduction in a multi-imager environment. Embodiments include methods, computer program products, and apparatuses for producing a near-field illumination using a near-field illuminator, the near-field illumination produced at a defined pulse train. A near-field image sensor may be exposed near the start of a near-field illumination pulse, and a far-field image sensor may be exposed between pulses of the near-field illumination. Some embodiments, additionally or alternatively, are configured for detecting an illuminator switch event, deactivating the near-field illuminator source, and producing, using a far-field illuminator source, a far-field illumination. Upon switching the illuminator source, some such embodiments are configured for exposing a far-field illuminator near the start of the far-field illumination pulse, and exposing a near-field image sensor near the start of the next available far-field illumination pulse.

  • Patent number: 11625547
    Abstract: Apparatuses, systems, and methods of manufacturing are described that provide improved tag identification. An example system includes a radio-frequency identification (RFID) scanner that receives a stream of RFID tags each associated with a respective article. The system further includes a first sensor attached to the RFID scanner that generates first positional data and a second sensor positioned separate from the first sensor that generates second positional data. The system also includes a computing device communicably coupled with the RFID scanner, the first sensor, and the second sensor. The computing device receives the stream of RFID tags, receives first positional data from the first sensor, receives second positional data from the second sensor, and determines an intended RFID tag from amongst the stream of RFID tags based upon the first positional data and the second positional data.
