Publication number: 20210303806Abstract: 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.Type: ApplicationFiled: March 26, 2021Publication date: September 30, 2021Inventors: Ka Man AU, Charles Joseph CUNNINGHAM, IV, Michael J.

Publication number: 20210274084Abstract: Embodiments of the disclosure relate generally to flicker reduction in a multi-imager environment. Embodiments include methods, computer program products, and apparatuses configured 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.Type: ApplicationFiled: February 28, 2020Publication date: September 2, 2021Applicant: Hand Held Products, Inc.Inventors: Benjamin HEJL, Ka Man Au, Erik Van Horn, David M.

Patent number: 10366380Abstract: A point of sale system capable of operating in an indicia-reading mode or a verification mode is disclosed. In the indicia-reading mode, the point of sale system configures its illumination, imaging, and processing to read indicia as part of a normal checkout process. If triggered by a user or by an event, the point of sale system may operate in a verification mode. In the verification mode, the point of sale system enables the necessary illumination, imaging, and processing to verify an item. This verification includes illuminating the item in a way that causes a noticeable response from a security mark (or marks) on the item. An image of the response may be captured and processed to authenticate/verify the item. The point of sale system may then respond to the verification and/or may store the image/results as a record of the verification.Type: GrantFiled: January 3, 2019Date of Patent: July 30, 2019Assignee: HAND HELD PRODUCTS, INC.Inventors: Erik Van Horn, Sean Philip Kearney, Patrick Anthony Giordano, Timothy Good, Chandler Dickinson, Ka Man Au, David Wilz, Sr., John A.

Patent number: 9685049Abstract: A barcode scanner should output one scanned result per scanned item at checkout. Scanners with large scan areas and multiple scan lines may scan an item more than once as it is dragged through the scan area during the checkout process. A timeout period, during which duplicate scans are ignored, may prevent duplicate scans from being transmitted. Scanners with integrated weight scales may require the use of the scan area for a weight measurement. As a result, weighed items may linger in the scan area longer than the regular timeout period and may be re-scanned. The invention embraces a method and system for mitigating this problem by using information from the scanned barcode and information from the scale to affect how duplicate barcode scans are handled for items requiring a weight measurement and not adversely affected with speed of input as may result with gating and virtual gating with disable/enable scanning commands.Type: GrantFiled: November 9, 2015Date of Patent: June 20, 2017Assignee: Hand Held Products, Inc.Inventors: Ka Man Au, John A.
