Abstract: Systems and techniques to assemble RFID tag can be employed in a manufacturing endeavor. An RFID tag assembling system includes an RFID module conveyor that moves a first substrate having multiple RFID modules, an RFID antenna conveyor that moves a second substrate having multiple RFID antennas with respect to and into alignment with the first substrate, and a joiner in proximity to the first substrate to separate the RFID modules from the first substrate and attach the RFID modules to the RFID antennas on the second substrate. The substrates can be reel-form substrates, and RFID tags can be formed in parallel. The system can also include an RFID module tester, and the RFID modules can be tested in parallel.

Abstract: These systems and techniques relating to RFID tags include current source control in RFID memory. According to an aspect, a radio frequency identification tag includes an antenna, a radio frequency interface coupled with the antenna, and a non-volatile memory including multiple memory cells, at least one of the memory cells including a floating gate, a control gate, and a dielectric there between. The non-volatile memory includes a controlled current source operable to modify the at least one memory cell. Additionally, the non-volatile memory can include a voltage supply line regulator that limits voltage supply based on a sensed operational current that results from the controlled current source in the non-volatile memory.

Abstract: Systems and techniques to provide radio frequency identification tags including a non-responsive state, which is independent of supplied power, initiated in conjunction with a tag communications reset. In general, in one implementation, a passive radio frequency identification tag includes an antenna, a radio frequency interface coupled with the antenna, and control logic that initiates a deep sleep state in response an event, the deep sleep state including a non-responsive state that is independent of supplied power, and the control logic providing a following state entered upon conclusion of the non-responsive state, where communications initiate from the following state.

Abstract: An RFID sensor system and method is disclosed. An RFID sensor system includes a conducting path having first and second conductors, and one or more RFID sensing transceivers spatially-distributed along the conducting path and capactively-coupled to the first and second conductors. The system further includes a controller that provides an AC signal on the conducting path, and receives signals from the one or more RFID sensing transceivers. The conducting path and RFID sensing transceivers can formed in a flexible substrate and mated together.

Abstract: A design and method for attaching an RFID chip to a conductive pattern is disclosed. According to the invention, multiple die are aligned with respective multiple conductive modules for structural and electrical attachment. As disclosed, the multiple die can be attached near simultaneously and without the need for intermediate handling. Therefore, substantial cost benefits are realized. Also disclosed is a method of making electrical connections employing the use of a laser. A photosensitive adhesive material is used to structurally secure the attachment.
