Connection bridges for dual interface transponder chip modules
Connection bridges (CBR) for dual-interface transponder chip modules (TCM) 200 may have an area which is substantially equal to or greater than an area of a contact pad (CP) of a contact pad array (CPA). A given connection bridge may be L-shaped and may comprise (i) a first portion disposed external to the contact pad array and extending parallel to the insertion direction, and (ii) a second portion extending from an end of the first portion perpendicular to the insertion direction to within the contact pad array (CPA) such as between C1 and C5. The connection bridge may extend around a corner of the contact pad array, may be large enough to accommodate wire bonding, and may be integral with a coupling frame (CF) extending around the contact pad array. The transponder chip modules may be integrated into a smart card (SC).
Arrangement for monitoring tools when machining rotationally symmetric workpieces
A multi-loop antenna and an RFID system are used for monitoring tools when machining rotationally symmetric workpieces. A multi-loop antenna is arranged on a tool carrier near a rotationally symmetric tool so that multi-loop antenna encloses the rotationally symmetric tool and the rotationally symmetric tool carries an RFID transponder. The position of this RFID transponder is arranged on the rotationally symmetric tool so that it is arranged in the electromagnetic ring field of the multi-loop antenna. The multi-loop antenna is arranged on the tool carrier so that it is possible to query the RFID transponder on the rotationally symmetric tool in any position while in motion and when at rest.
System and method for radio frequency identification tag reuse
A label includes a recycled sloop type radio frequency identification (RFID) tag from a previously used label. The RFID tag is removed from the previous label by cutting the RFID tag from the previous label using a laser, die, or cutting wheel. The conductor antenna of the RFID tag can be cut to remove damaged portions or change operation of the RFID tag. A slot in the conductor antenna can be resized to tune the RFID tag to allow the RFID tag to be used for the same application use or a different application use. The label can include indicia such as machine readable indicia and human readable indicia. The extracted RFID tag can include portions of the previous label, which can be free of indicia.
RFID System
A magnetic field focusing assembly includes a magnetic field generating device configured to generate a magnetic field, and a split ring resonator assembly configured to be magnetically coupled to the magnetic field generating device and configured to focus the magnetic field produced by the magnetic field generating device.
DEVICE FOR STORING ELEMENTS, ASSOCIATED INSTALLATION AND ASSOCIATED COMMUNICATION METHOD
Disclosed is a device for storing elements each including a first wireless communication unit, the device including: —a receiving support receiving the elements; —a second wireless communication unit generating waves and communicating with each first unit according to a communication protocol, a communication zone being a three-dimensional zone in which the second unit communicates with each first unit when each first unit is located in the zone and does not communicate with a first unit when the first unit is located outside the zone; —a waveguide able to guide the generated waves so that a dimension of the communication zone is strictly greater than a reference dimension, the reference dimension being equal to the dimension of the communication zone when the storage device is without waveguides.
WIRELESS TAG COMMUNICATION DEVICE, IMAGE FORMING APPARATUS, AND METHOD
A wireless tag communication device includes an antenna, a first maximum value acquiring unit, a second maximum value acquiring unit, a first minimum value acquiring unit, a second minimum value acquiring unit, and a polarization direction determining unit. The wireless tag communication device acquires, for each of n wireless tags provided on a sheet, a maximum value M1(k) of a received power intensity of the wireless tag when the radio wave is transmitted from the antenna to the sheet in a first polarization direction; acquires, for each of the wireless tags, a maximum value M2(k) of a received power intensity of the wireless tag when the radio wave is transmitted from the antenna in a second polarization direction that is different from the first polarization direction; acquires a minimum value m1 of M1(k); acquires a minimum value m2 of M2(k); and determines the polarization direction along which one of m1 and m2 that is not smaller is acquired as the polarization direction of the radio wave transmitted to the sheet.
