Patent number: 9064167Abstract: A scanning code symbol reading system includes an analog scan data signal processor for producing digitized data signals, wherein during each laser beam scanning cycle, a light collection and photo-detection module generates an analog scan data signal corresponding to a laser scanned code symbol, an analog scan data signal processor/digitizer processes the analog scan data signal to generate digital data signals corresponding thereto, and a synchronized digital gain control module automatically processes the digitized data signals in response to start of scan (SOS) signals generated by a SOS detector. The synchronized digital gain control module generates digital control data which is transmitted to the analog scan data signal processor for use in controlling the gain of a signal processing stage in the light collection and photo-detection module and/or analog scan data signal processor, during the corresponding laser beam scanning cycle.Type: GrantFiled: June 16, 2014Date of Patent: June 23, 2015Assignee: Metrologic Instruments, Inc.Inventors: Tao Xian, Gennady Germaine, Xiaoxun Zhu, Ynjiun Paul Wang

Patent number: 8985456Abstract: A strobe illumination control process for use in a digital image capture and processing system includes illuminating an object in the field of view with different pulses of illumination over a pair of consecutive video image frames, detecting digital images of the illuminated object over these consecutive image frames, and decode processing the digital images. In a first illustrative embodiment, upon failure to read a symbol in one of the first and second images, these digital images are analyzed in real-time, and based on the results of this real-time image analysis, the exposure time is adjusted during subsequent image frames. In a second illustrative embodiment, upon failure to read a symbol in one of the first and second images, these digital images are analyzed in real-time, and based on the results of this real-time image analysis, the energy level of the illumination is adjusted during subsequent image frames.Type: GrantFiled: March 28, 2013Date of Patent: March 24, 2015Assignee: Metrologic Instruments, Inc.Inventors: Xiaoxun Zhu, Ynjiun Paul Wang

Patent number: 8976030Abstract: A checkout system is provided for carrying out a two-factor authentication process where coded products are purchased and theft activity might be pursued. The system typically includes an identification code reader for reading product identification codes (e.g. UPC bar code symbols or EPC-encoded RFID tags) on products that are passed through the point of sale (POS) and a security code detector/reader for automatically detecting/reading a security code (e.g. implemented as an EAS tag or an RFID tag) at the POS. During product checkout operations, the identification code reader reads identification codes, and the security code detector/reader detects or reads security codes applied to products. Collected identification and security data is automatically processed using identification and security data stored in a database to determine whether or not each product being purchased at the POS is in compliance or not in compliance with a two-factor authentication process supported by the checkout system.Type: GrantFiled: April 22, 2013Date of Patent: March 10, 2015Assignee: Metrologic Instruments, Inc.Inventors: Charles Cunningham, Timothy Good, Sean Philip Kearney, Michael Miraglia, Thomas Amundsen, Patrick Giordano, Yujiun Paul Wang, Xiaoxun Zhu
