  • Patent number: 10249160
    Abstract: Successive products associated with targets to be electro-optically read are swiped, in their respective turns, past a window in a point-of-transaction workstation. A motion detector detects movement of each product. A reader electro-optically reads a target associated with each moving product. If the target associated with each moving product has not been read, then this event is deemed suspicious, and the event is flagged for a security investigation designed to deter product theft by sweethearting.
    Type: Grant
    Filed: November 28, 2016
    Date of Patent: April 2, 2019
    Assignee: Symbol Technologies, LLC

  • Patent number: 9489554
    Abstract: A reader electro-optically reads symbols associated with products to obtain read data, and a controller decodes the read data to obtain symbol data indicative of the associated products. Reading performance is assessed by collecting time-to-decode metadata by determining each decode time period that is taken for each symbol data to be successfully decoded, by associating the collected time-to-decode metadata with the symbol data, by comparing the collected time-to-decode metadata with a predetermined long amount of decode time that is indicative of a slow reading performance, by storing each decode time period that at least equals said predetermined long amount of decode time, and by storing the symbol data associated with each stored decode time period.

  • Patent number: 8899481
    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.

  • Patent number: 8783570
    Abstract: An imaging-based bar code reader that includes an imaging and decoding system. Focusing optics and a sensor array define a field of view. A data processor has a memory for storing a pattern definition of previously imaged OCR characters and comparing a format of said previously stored characters to a present image to determine a character content of the present image.
