Patent number: 10509993Abstract: A method for providing identification and access with respect to a passive radio-frequency tag in a tag population, the passive tag being configured for receiving ACK commands including an identification parameter, the method including receiving an initiating command for identifying and accessing a tag, the initiating command including a slot number having a first value if a value in a slot counter of the tag is equal to the first value, then transitioning to an Open or a Secured state, otherwise transitioning to an Arbitrate state in a case where the tag has transitioned to the Arbitrate state, receiving a command for repeating a tag access request, referred to as repetition command, the command including a slot number having a second value, different from the first value, the second value being equal to the value in the slot counter of the tag, transitioning to the Open or Secured state, receiving an ACK command, ignoring the ACK command.Type: GrantFiled: November 15, 2017Date of Patent: December 17, 2019Assignee: EM Microelectronic-Marin SAInventors: James J Springer, Tomas Hrdy, Martin Jager

Patent number: 10229300Abstract: A method for providing identification and access with respect to a passive radio-frequency tag in a tag population, the passive tag receiving ACK commands includes an identification parameter in the form of a 16-bit number. The method includes a step of receiving a command for initiating an inventory round or a command for initiating a tag access, generating a 16-bit value referred to as first or second binding handle, backscattering the first or second binding handle, receiving an ACK command, and analyzing the identification parameter of the ACK command, and in a case where the identification parameter includes the reader identifier then ignoring the ACK command.Type: GrantFiled: November 8, 2017Date of Patent: March 12, 2019Assignee: EM Microelectronic-Marin SAInventors: James J. Springer, Tomas Hrdy, Martin Jager

Publication number: 20180165482Abstract: The method relates to a method for providing identification and access with respect to a passive radio-frequency tag in a tag population, the passive tag being configured for receiving ACK commands comprising an identification parameter in the form of a 16-bit number, said method comprising the following steps: receiving a command for initiating an inventory round or a command for initiating a tag access, said command comprising, as a parameter, a number comprising an identifier of a reader generating a 16-bit value referred to as first or second binding handle, said first or second binding handle comprising N juxtaposed bits forming the reader identifier backscattering said first or second binding handle receiving an ACK command analyzing the identification parameter of said ACK command, and in a case where said identification parameter comprises the reader identifier then ignoring said ACK command.Type: ApplicationFiled: November 8, 2017Publication date: June 14, 2018Applicant: EM Microelectronic-Marin S. A.Inventors: James J. SPRINGER, Tomas Hrdy, Martin Jager

Patent number: 9537647Abstract: The invention concerns a method and device for processing UHF signals for an EPC communication. The method includes the steps of picking up UHF signals by an antenna of the device for processing UHF signals, creating an envelope signal from the UHF signals picked by the antenna in a demodulator, processing the envelope signal and decoding critical TRcal symbol and data in a logic unit of the device. Furthermore, the method includes the steps of interpreting the critical TRcal symbol and data, storing the interpreted data, encoding transmit data, modulating by encoded data in a modulator, and clocking the steps as above by a local oscillator. In the step of processing the envelope signal, the critical TRcal symbol is processed by a high frequency clock and data are processed by a low frequency clock.Type: GrantFiled: February 25, 2016Date of Patent: January 3, 2017Assignee: EM Microelectronic-Marin SAInventors: Tomas Marek, Tomas Hrdy, Lubos Hradecky
