The AGV/BOT may also predict the next RFID tag.Type: ApplicationFiled: October 31, 2012Publication date: May 1, 2014Applicant: Rockwell Automation Technologies, Inc.Inventors: Kevin M.

Publication number: 20140111311Abstract: A method and apparatus for operating an RFID scanner is provided herein. During operation, an RFID scanner will utilize beamforming techniques to appropriately beamform an interrogation signal. A first beamforming scheme will be used for a first task (e.g., EAS, inventory management, point-of-sale mode scanning of a first area, . . . , etc.) and a second beamforming scheme will be used for a second task.Type: ApplicationFiled: October 24, 2012Publication date: April 24, 2014Applicant: SYMBOL TECHNOLOGIES, INC.Inventors: MICHAEL J. KOCH, BENJAMIN J. BEKRITSKY, ALEXANDER M. JACQUES, NEERAL SESHADRI

Patent number: 8704640Abstract: A passive wireless memory device includes a memory unit and a passive tag. The passive tag converts data stored in the memory unit into a data packet in response to first to third data request signals from a reader and transmits the data packet to the reader. The passive tag determines the size of the data packet in response to the channel state predicting flag and the second and third data request signals.Type: GrantFiled: February 11, 2011Date of Patent: April 22, 2014Assignee: Samsung Electronics Co., LtdInventors: Youngsun Han, Iljong Song, Jihun Koo, Seonwook Kim, Joongoo Lee, Seokjoong Hwang, Yeoul Na

Patent number: 8698601Abstract: A method for card-reading anti-collision with automatic frequency hopping is provided, which is used for a system in which a card reader simultaneously reads a plurality of cards in radio frequency identification technologies. The method comprises: both the card reader and the cards to be read are configured to have an automatic frequency-sweep function and a function of hopping from a current channel to another channel, and to store access addresses and transaction addresses; when the card reader is in a frequency-hopping card-seeking state, it is in an n-channel frequency-hopping working state, in which, the access address of each channel is the same, and the card reader reads the cards by means of hopping frequencies in a sequence iteratively through n channels. When the card reader detects that two or more cards collide, the card reader sends a command of random frequency hopping, making all the conflicting cards to hop to other channels randomly and to wait to access those channels.Type: GrantFiled: May 6, 2011Date of Patent: April 15, 2014Assignee: Nationz Technologies, Inc.Inventors: Yingtong Sun, Jianhui Liu

Patent number: 8698629Abstract: Radio Frequency Identification (RFID) readers may transmit one or more encapsulated commands within the payload of an encapsulating command. An encapsulated command includes at least a command code and an instruction. A reader may instruct a tag to store the encapsulated command(s) or instruction(s) for later execution. A sequence of encapsulated commands may be contained within one encapsulating command or spread across multiple encapsulating commands. The sequence of encapsulated commands, or the sequence of instructions associated with the encapsulated commands, may form a program. The reader may cause the tag to execute the instructions or program upon receipt, upon a trigger event, serially or in parallel, and/or may cause the tag to modify the instructions or program by adjusting parameters. The reader may later instruct a tag to execute the instructions or program via another command which, in some cases, may be sent prior to tag singulation.Type: GrantFiled: June 20, 2011Date of Patent: April 15, 2014Assignee: Impinj, Inc.Inventors: Theron Stanford, Christopher J.

Patent number: 8698600Abstract: A radio frequency identification (RFID) tag access method and a circuit applied to an RFID tag to determine whether to respond to a command sent by a reader are provided. According to the access method, an extra reference value is used for adjusting a parameter or a count value, so as to increase or decrease the probability of generating a condition matching with a command sent by the reader. Therefore, the probability of the tag being accessed is adjusted, and the tag carrying urgent information shall be accessed prior to the tag without urgent information.Type: GrantFiled: September 1, 2009Date of Patent: April 15, 2014Assignee: MStar Semiconductor, Inc.Inventor: Chih Hua Huang

Patent number: RE45061Abstract: Communication between a remote locator and a transponder is used to determine the relative position of the transponder. The transponder and locator each include a transmitter and a receiver. The locator transmits an inquiry in the form of a relatively powerful cyclically encoded signal with repetitive elements, uniquely associated with a target transponder. Periodically, each transponder correlates its coded ID against a possible inquiry signal, determining frequency, phase and framing in the process. Upon a match, the transponder transmits a synthesized response coherent with the received signal. The locator integrates multiple cyclical response elements, allowing low-power transmissions from the transponder. The locator correlates the integrated response, determines round-trip Doppler shift, time-of-flight, and then computes the distance and angle to the transponder. The transponder can be wearable, bionically implanted, or attached to, or embedded in, some object.Type: GrantFiled: January 11, 2012Date of Patent: August 5, 2014Assignee: Santa Monica Semiconductor, LLCInventor: Lawrence J.
