Publication number: 20110025462Abstract: Systems and methods for saving power in a distributed RFID system are provided. One RFID reader includes a RFID radio, a data communication radio, and a controller. The controller is configured to compare a current list of RFID tags responding to a current interrogation signal and a previous list of RFID tags responding to a previous interrogation signal to determine if there has been a change in RFID tags responding to the interrogation signals. The controller is also configured to command the data communication radio to transmit a signal to an external computing device if there has been the change in RFID tags, the signal indicative of the change, or not transmit the signal if there has not been a change. An RFID system includes a central computing device, multiple RFID tags, and multiple RFID readers similar to the above RFID reader.Type: ApplicationFiled: July 28, 2009Publication date: February 3, 2011Applicant: SYMBOL TECHNOLOGIES, INC.Inventors: Miklos Stern, Ed Barkan, Benjamin Bekritsky

Publication number: 20080023551Abstract: An omnidirectional scanning system and method are provided for reading at least one optical code within a field of view of the scanning system and oriented in an orientation included in a set of multiple orientations. The omnidirectional scanning system includes at least one processor for operating the scanning system in at least two modes including a first mode which is a non-restricted omnidirectional scan mode for reading the at least one optical code oriented in any orientation of the set of multiple orientations, and a second mode which is a restricted omnidirectional scan mode for reading the at least one optical code oriented in an orientation of a selectable reduced set of the set of multiple orientations. The method includes the steps of operating the system in a mode selected from the at least two modes including the first mode and the second mode.Type: ApplicationFiled: October 5, 2007Publication date: January 31, 2008Inventors: Thomas Boehm, Morgan Fuchs, Daniel Gonzalez, Patrick Salatto, Joel Kahn, George Lasher, Ed Barkan

Publication number: 20060065734Abstract: A system and method for processing scanner signals by storing both a standard digitizer signal and a more detailed digitizer signal for decoding. The decoder can then use the standard digitizer signal by default and in those cases when the bar code pattern cannot be decoded using the standard digitizer signal the decoder may access the more detailed digitizer signal.Type: ApplicationFiled: September 30, 2004Publication date: March 30, 2006Inventors: William Sackett, Anthony Biuso, Ed Barkan, Frederick Schuessler, James Giebel, Wynn Aker

Publication number: 20050077359Abstract: A system and method are provided for reading at least one optical code, including an omnidirectional optical code scanner system for illuminating, scanning and decoding at least one optical code within a field of view of the scanning system and oriented in an orientation included in a set of multiple orientations. The scanner system includes an actuator assembly having circuitry for providing for user selection of a mode selected from the group of modes consisting of: an omnidirectional mode for performing a read operation for reading an optical code oriented in any orientation included in the set of multiple orientations, a restricted omnidirectional mode for performing a read operation for reading the optical code when oriented only in an orientation of a reduced set of the set of multiple orientations; and an aim mode for illuminating a target object and disrupting a corresponding read operation; and circuitry for generating a signal indicative of the mode selection.Type: ApplicationFiled: April 14, 2004Publication date: April 14, 2005Inventors: Thomas Boehm, Morgan Fuchs, Daniel Gonzalez, Patrick Salatto, Joel Kahn, George Lasher, Ed Barkan

Patent number: 6691919Abstract: An integrated optical communication and barcode scanning module suitable for use with portable electronic devices is provided. In a first mode of operation the module functions as an Infrared Data Association (IrDA) compatible communications interface. In a second mode of operation, IrDA communications is disabled, and the module functions as a barcode scanner. The module may be switched back and forth between the two modes of operation or operated simultaneously.Type: GrantFiled: December 23, 1999Date of Patent: February 17, 2004Assignee: Symbol Technologies, Inc.Inventors: Joseph Katz, Chinh Tan, David Goren, Miklos Stern, Ed Barkan, Howard Shepard, Frederick Wood

Patent number: 6578767Abstract: An optical scanning module and a scanner incorporating the scanning module for reading bar codes and other optical indicia that consists of a printed circuit board, an elongated elliptical aperture in the scanning module that is spaced from the circuit board, a light source mounted on the printed circuit board for projecting at least one beam of light through the aperture and onto a dataform to be read, and a detector mounted on the printed circuit board for sensing light reflected from the dataform and through the aperture. Light baffle is preferably used to isolate light source from the detector in the optical scanning module of the present invention.Type: GrantFiled: July 14, 2000Date of Patent: June 17, 2003Assignee: Symbol Technologies, Inc.Inventors: Ed Barkan, Howard Shepard

Publication number: 20010055978Abstract: A portable data device system includes a portable data device and a cradle for receiving the portable data device. The cradle is arranged to recharge the portable data device power supply and/or upload or download information to and from the portable data device. The cradle and portable data device are in wireless communication allowing a minimum of processing and data storage capability at the front end and hence operation of the portable data device as a thin client.Type: ApplicationFiled: August 5, 1997Publication date: December 27, 2001Inventors: ALAN HERROD, ED BARKAN, JOHN KLEIN, SAROSH VESUNA, SIMON BARD

Patent number: 6119944Abstract: A hand-held bar code reader, in particular a bar code wand is used by a consumer to read bar code information accompanying a product displayed at a retail outlet. The bar code information can be presented in, for example, UPC format and carries information relating to the products. The consumer subsequently down-loads information stored in the reader via a suitable interface to a personal computer which accesses information identified by a address included in or comprising the bar code information. The site contains additional information such as price information concerning the advertised product and the consumer may be able to pay for and order the product directly via the site. As a result the consumer has a simple reminder of the product, is able to obtain additional information concerning the product with minimum difficulty and can obtain the product itself with maximum ease.Type: GrantFiled: February 3, 1997Date of Patent: September 19, 2000Assignee: Symbol Technologies, Inc.Inventors: Altaf Mulla, Robert Sanders, John Lert, Jr., Joseph Katz, Chinh Tan, Ed Barkan, Howard Shepard

Patent number: 5250790Abstract: A hand-mounted scanning system for reading indicia having parts of different light reflectivity, including a housing having a window and an actuatable electro-optical scanner in the housing for projecting a light beam through the window to indicia to be read, for scanning the indicia. The system further detects light of variable intensity that is reflected off the indicia to generate an electrical signal representative of the indicia. The housing is mounted on a glove worn on an operator's hand and the scanner initiates reading of the indicia upon movement of the operator's hand, or automatically by object recognition.Type: GrantFiled: June 12, 1992Date of Patent: October 5, 1993Assignee: Symbol Technologies, Inc.Inventors: Boris Melitsky, Mark Krichever, Ed Barkan, Howard M.

Patent number: 5191197Abstract: A hands-free scanning system for reading indicia having parts of different light reflectivity, including a housing having a window and an actuatable electro-optical scanner in the housing for projecting a light beam through the window to indicia to be read, for scanning the indicia. The system further detects light of variable intensity that is reflected off the indicia to generate an electrical signal representative of the indicia. The housing is mounted on an arm of an operator and the scanner initiates reading of the indicia upon movement of the operator's hand relative to the arm by means of an actuator switch.Type: GrantFiled: May 13, 1991Date of Patent: March 2, 1993Assignee: Symbol Technologies, Inc.Inventors: Boris Metlitsky, Mark Krichever, Ed Barkan, Howard M.
