Publication number: 20240104333Abstract: An RFID assembly (10) includes an RFID chip (14) having a coupling loop (15) formed as part of the RFID chip (14). In this manner, the RFID chip (14) can be inductively coupled to a far-field antenna (16) for RFID communications, without any physical connections between the RFID chip (14) and the coupling loop (15) and/or the far-field antenna (16). This results in a high temperature resistance of the RFID assembly (10), which can be advantageously used, in particular, during tracking of parts in assembly processes requiring higher temperatures.Type: ApplicationFiled: September 13, 2023Publication date: March 28, 2024Inventors: Eric Suligoj, Christian Mirus

Patent number: 11934907Abstract: A method to check if a connector system with a Connector Position Assurance (“CPA”) member is in a closed position. The method includes providing an RFID-tag reader that is positioned at a distance D to the integrated circuit enabling far-field RFID communication and not permitting near-field RFID communication. Further, the method includes checking the readability of the integrated circuit with the RFID-tag reader and issuing an alert signal if the integrated circuit is not readable by the RFID-tag reader indicating that the CPA member is not in the closed position.Type: GrantFiled: December 29, 2020Date of Patent: March 19, 2024Assignee: ASSA ABLOY ABInventors: Jean-Miguel Robadey, Christian Mirus

Patent number: 10176422Abstract: The RFID tag comprises an antenna (11) connected to a wireless communication device (18). The antenna comprises a conductive planar surface and a slot (14) extending at least in a part of said conductive planar surface, the slot (14) forming a non-conductive area of the antenna and defining a first part (12) and a second part (13) of the antenna. The wireless communication device comprises two contact pads (16, 17) being electrically connected respectively each to one of the first and second part of the antenna. The slot comprises a closed end formed by a further conductive part connecting said first and second parts the antenna and further comprises at least one conductive bridge (19-19??, 20, 21-21?) connecting said first and second parts of the antenna, the conductive bridge allowing to tune the resonance frequency of the tag by varying the length of the electrical path between the pads from the wireless communication device in the antenna.Type: GrantFiled: June 9, 2015Date of Patent: January 8, 2019Assignee: ASSA ABLOY ABInventors: Elies Ennabli, Jean-Miguel Robadey, Christian Mirus

Patent number: 7240838Abstract: A reader for identifying passive transponders includes an antenna for receiving a first signal (Tx) from the reader and for transmitting a second signal (Rx). The reader includes: a time base generating a sinusoidal signal, a control circuit, a modulator for transmitting to the control circuit data to modulate the sinusoidal signal so as to generate a signal carrying commands which, when it is received by the antenna of the transponder, forms the first signal (Tx), a demodulator, a decoder, a communication interface and an antenna. The demodulator, which is connected to the antenna to receive the second signal (Rx), includes two multipliers, one being of the inverter type, and an adder designed to combine the data derived from the multipliers. A system including first and second devices that communicate by way of a modulated transmitted signal is also described.Type: GrantFiled: December 12, 2005Date of Patent: July 10, 2007Assignee: MBBS Holding S.A.Inventors: Ngoc-Chau Bui, Christian Werner, Yves Gaudenzi, Martial Benoit, Vincent Cassi, Christian Mirus, Jean-Daniel Chatelain, Jacques Kowalczuk

Patent number: 6891475Abstract: The invention concerns a radio-frequency transponder (12) for contact-free identification with a reader (10), comprising: an antenna (24), an analog circuit (25) including a capacitor (32) an AC-DC converter (34), a modulator (40) and a demodulator (38), a logic control circuit (26), a storage unit (27). Said transponder (12) is designed such that: the antenna (24) and the capacitor (32) form together a resonant circuit, the clock extractor (36) processes the first signal (Tx) to extract therefrom a clock signal addressed to said modulator (38) as long as the voltage of said signal (Tx) exceeds a first threshold value, the converter (34) transforms the first signal (Tx) into a rectified signal, to power the transponder (12). The performances of the transponder, and more particularly energy recuperation and data transmission rate, are improved by the fact that the analog circuit comprises two clock extractors, one of low level type (35), the other of the high level type (36).Type: GrantFiled: July 17, 2001Date of Patent: May 10, 2005Assignee: MBBS Holding S.A.Inventors: Ngoc-Chau Bui, Christian Werner, Yves Gaudenzi, Martial Benoit, Vincent Cassi, Christian Mirus, Jean-Daniel Chatelain, Jacques Kowalczuk
