Patent number: 8669874Abstract: RFID tags are used for many purpose including tracking. RFID interrogators are used to retrieve information from tags. In many applications, RFID interrogators and RFID tags remain stationary during interrogation. Regions of low energy due to interference from either additional antenna or reflections from RFID tags and objects can impede or prohibit the reading of RFID tags residing in such regions. Stirring of the generated electromagnetic field is a method of moving around the regions of low energy, where tags can not be read, during the interrogation process. Mechanical stirring is accomplished by introducing a conductor into the electromagnetic field and moving it about in the field. Solid state stirring is accomplished by introducing a variable conductor into the field and varying the conductivity of the variable conductor. Mathematical stirring is accomplished by use of a plurality of antenna and controlling the phase difference between the antenna in a configuration known as phased antenna arrays.Type: GrantFiled: December 30, 2010Date of Patent: March 11, 2014Assignee: Neology, Inc.Inventors: James Robert Kruest, Gary Bann

Patent number: 8593283Abstract: Embodiments of the invention pertain to Radio Frequency Identification (RFID) method and system using an antenna array, an array controller, and control algorithms. Embodiments of the invention can induce strong radio-frequency (RF) excitation, for a given level of radiated RF power, at any point within an arbitrary inhomogeneous medium. For RFID applications, one typical inhomogeneous medium is an ensemble of cases on a pallet. Another typical medium is a warehouse environment having stored goods together with shelving and other material present. An embodiment of the invention is applicable to the process of reading battery-less, or “passive” RFID tags, which rely on incident RF electromagnetic fields established by RFID readers to power the electronic circuitry within the tags.Type: GrantFiled: January 30, 2009Date of Patent: November 26, 2013Inventor: Mark H. Smith

Patent number: 8587411Abstract: RFID reader systems, readers, components, software and methods cause RFID tags to backscatter a combination made from at least portions of a first code and a second code, without transmitting any commands in the interim. The first and/or second codes may include a tag response to a reader challenge. In a number of embodiments, a separate command does not have to be sent for reading the second code along with the first code, thereby saving time in inventorying the tags. Plus, the combination can enable reading tag codes during tag manufacturing that are not otherwise readily available to read in the field. In some embodiments, the combination may further include one or more error-checking codes.Type: GrantFiled: December 10, 2012Date of Patent: November 19, 2013Assignee: Impinj, Inc.Inventor: Christopher J. Diorio

Patent number: 8587431Abstract: A method and apparatus involve a radio frequency identification tag that receives a wireless signal containing a message type conforming to an extension of a standard communication protocol and having an extended services segment, the tag then transmitting the extended services segment through an extended services interface. According to a different aspect, a method and apparatus involve a radio frequency identification tag that stores data which includes respective information regarding each of multiple extended services, and that responds to receipt of a wireless signal which is an extension to a standard protocol by transmitting a further wireless signal which is an extension to the protocol and contains at least part of the data. According to yet another aspect, a method and apparatus involve a radio frequency identification tag that responds to receipt of one wireless signal by transmitting a further wireless signal containing information regarding multiple sensors.Type: GrantFiled: May 28, 2010Date of Patent: November 19, 2013Assignee: Savi Technology, Inc.Inventors: Richard L. Schnell, David B. Koons

Patent number: 8587489Abstract: This invention relates to dynamically controlled, electronic article surveillance (EAS) systems whereby an array of antenna elements is digitally phased and actively driven for concurrent transmission, and digitally phased and combined in the receiver unit to improve security tag detection. In particular, the individual frequency and phase of the plurality of the transmit/receive signals are rapidly varied to allow for automated manipulation (steering) of the transmit field pattern and receive field sensitivity. It is the object of this invention to achieve the following features via means of digital phasing and dynamic computer control: sufficient far-field cancellation, null-free detection and uncompromised detection performance regardless of tag's orientation.Type: GrantFiled: June 6, 2008Date of Patent: November 19, 2013Assignee: Checkpoint Systems, Inc.Inventors: Harry Oung, Kefeng Zeng

Patent number: 8587432Abstract: Embodiments include methods and apparatus for detecting proximity of an electronic article surveillance (EAS) tag. A proximity detection system (e.g., a radio frequency identification (RFID) tag reader) detects a presence of an object within a first area. In response to detecting the proximity of the object, an EAS tag reader alters characteristics of an EAS tag detection signal that is produced by the EAS tag reader in order to detect an EAS tag within range of the EAS tag reader.Type: GrantFiled: August 20, 2010Date of Patent: November 19, 2013Assignee: Symbol Technologies, Inc.Inventor: Altaf Mulla

Patent number: 8588686Abstract: A Method and system for remote power distribution and networking for passive devices is provided. In this regard, a sensor comprising a leaky wave antenna may be powered utilizing energy from a radio frequency signal received via the leaky wave antenna. The sensor may be operable to recover a baseband signal from the received radio frequency signal. The sensor may be operable to generate one or more sensor readings in response to the received baseband signal. The sensor may be operable to communicate the sensor reading to a source of the received radio frequency signal via a backscattered signal. The backscattered signal may be generated by controlling spacing between surfaces of the leaky wave antenna. The backscattered signal may be generated by switching a load in and out of a receive path of the sensor and/or by switching between a plurality of feed points of the leaky wave antenna.Type: GrantFiled: June 9, 2010Date of Patent: November 19, 2013Assignee: Broadcom CorporationInventors: Ahmadreza Rofougaran, Maryam Rofougaran
