Patent number: 9213960Abstract: A method for filtering scanned objects displayed on a reader is provided. The reader may scan one or more transponders, and obtain, from a database, an image for each scanned transponder. Each transponder may be associated with an object (e.g., an item of retail inventory). The obtained image for each object may be presented on an interface, and a selection of an object category may be received using the obtained images. A determination may be made as to which objects are associated with the selected object category. A display screen may display data associated with only the objects associated with the selected object category.Type: GrantFiled: May 13, 2014Date of Patent: December 15, 2015Assignee: HAND HELD PRODUCTS, INC.Inventors: Joseph Vargas, Tom Plocher, Sriharsha Putrevu, Ynjiun Wang

Patent number: 8950678Abstract: An optical reader for decoding an encoded symbol character of a symbology includes a scan data signal processor having as an input a scan data signal encoding information representative of the encoded symbol character. The scan data signal processor includes a first time delay stage adapted to provide a primary phase waveform from the scan data signal, a second time delay stage adapted to provide an early phase waveform from the scan data signal, and a third time delay stage adapted to provide a delayed phase waveform from the scan data signal. The early phase waveform has a propagation delay less than the primary phase waveform, and the delayed phase waveform has a propagation delay greater than the primary phase waveform. The scan data signal processor further includes a peak window detection stage for generating a peak window timeframe when an amplitude of the primary phase waveform is greater than, less than, or equal to both an amplitude of the early phase waveform and the delayed phase waveform.Type: GrantFiled: November 17, 2010Date of Patent: February 10, 2015Assignee: Hand Held Products, Inc.Inventors: Gennady Germaine, Tao Xian, Chen Feng, Ynjiun Wang, Xiaoxun Zhu, Stephen Colavito, Robert Blake

Patent number: 8146820Abstract: The invention features a system and method to automatically focus an image reader using a single frame of image data. The method comprises exposing sequentially a plurality of rows of pixels in the image sensor. The method further comprising varying in incremental steps the focus of the image reader's optical system from a first setting where a distinct image of objects located at a first distance from the image reader is formed on the image sensor to a second setting where a distinct image of objects located at a second distance from the image reader is formed on the image sensor. As part of the method, the varying of the focus of the optical system occurs during the exposure of the plurality of rows of pixels.Type: GrantFiled: November 2, 2009Date of Patent: April 3, 2012Assignee: Hand Held Products, Inc.Inventors: Ynjiun Wang, William H.
