Patent number: 9111190Abstract: A radio frequency identification (RFID) tag reading system having a phased antenna array accurately locates RFID tags in a controlled area, by steering an interrogating beam over the controlled area to interrogate the tags and generate return modulated RF signals. A primary receiver steers a primary receive beam at a primary steering angle that is fixed during each tag interrogation. A primary demodulator demodulates and reconstructs the received return modulated signals. A secondary receiver, independently of the primary receiver, steers a secondary receive beam at a plurality of secondary steering angles. A secondary correlator/demodulator demodulates the combined return modulated signals, and utilizes the reconstructed signal reconstructed by the primary demodulator at each of the secondary steering angles. Both the primary and the secondary receivers cooperate to accurately locate the same tag.Type: GrantFiled: January 16, 2013Date of Patent: August 18, 2015Assignee: Symbol Technologies, LLCInventors: Alexander M.

Patent number: 9092684Abstract: An imaging reader is worn by a user. The reader has an imaging assembly that has a solid-state imager with an array of image sensors and a lens assembly. In a reading mode, the imaging assembly captures and projects light as an image onto the array. A controller detects a user's finger pointing at a symbol proximal to a tip of the finger in the image, and generates a control signal when the finger obstructs the symbol in the image. Upon receipt of the control signal, the controller automatically controls a drive to move the imager and/or a lens of the lens assembly to an adjusted position in which the symbol in the image is unobstructed by the finger. The unobstructed image of the symbol is processed into identifying data, and the data is transmitted away from the housing to a remote host device.Type: GrantFiled: January 8, 2015Date of Patent: July 28, 2015Assignee: Symbol Technologies, LLCInventors: Sundaresan Sundaram, Kavya Babu, Suresh Raj, Sajan Wilfred
