| 20090320139 | TRANSPONDER INCORPORATED INTO AN ELECTRONIC DEVICE - An electronic device. The device comprises a metalization layer and an integrated circuit chip incorporated into the device wherein the integrated circuit chip is capacitively coupled to the metalization layer. The device comprises a first substrate having the metalization layer formed on the substrate, a cap layer covering at least the entire metalization layer and at least a portion of the first substrate not covered by the metalization layer. The integrated circuit chip is coupled to the first substrate, and is placed in proximity and in non-physical contact with the metalization layer. A conductive layer is attached to the integrated circuit chip. The conductive layer has at least a portion placed in a non-physical contact with the metalization layer. The integrated circuit chip is capacitively coupled to the metalization layer through the conductive layer and the metalization layer. | 12-24-2009 |
| 20100181381 | RADIO FREQUENCY IDENTIFICATION (RFID) TAG FOR AN ITEM HAVING A CONDUCTIVE LAYER INCLUDED OR ATTACHED - An RFID device. The device comprises a conductive layer formed on a first substrate. An opening line (or two or more opening lines) is formed in the conductive layer to make the conductive layer a part of an antenna structure. An integrated circuit chip is placed over at least a portion the opening line and coupled to the conductive layer. The integrated circuit chip is electrically interconnected to the conductive layer. | 07-22-2010 |

| 20090231105 | Multistatic Antenna Configuration For Radio Frequencey Identification (RFID) Systems - Methods and apparatuses for configuring antennae of radio frequency identification reader systems. In one aspect of an embodiment, a radio frequency identification (RFID) reader system, includes: a receiver; a radio frequency (RF) source for signal transmission; and a switch matrix coupled with the receiver and the radio frequency sources to selectively couple the receiver and the radio frequency source to a plurality of non-collocated antennae. When in a first mode, the switch matrix connects the radio frequency source to a first one of the antennae for signal transmission and the receiver to a second one of the antennae for signal reception; and when in a second mode, the switch matrix connects the first one of the antennae for signal reception and, in one example, the second one or another one of the antennae to the RF source for signal transmission. | 09-17-2009 |
| 20100207739 | METHODS AND APPARATUSES TO IDENTIFY DEVICES - Embodiments of the present invention include systems with Readers and Tags in which a Reader queries the Tags with a parameter that includes a level of probability of reply according to which the Tags individually and randomly decide whether or not to reply. In one embodiment, the Tags can switch between two states: A and B. The query command also specifies a state (A or B) so that only the Tags in the specified state can reply. After successfully sending the Tag identification data from a Tag to the Reader, the Tag switches to the other state from the specified state. In one embodiment, the operations about the two states are symmetric. In one embodiment, the Tags can remember the parameters used in a query so that a short form of query command can be used to repeat the query with the same query parameters. | 08-19-2010 |

| 20080204244 | METHOD AND APPARATUS FOR TESTING RFID DEVICES - A method and apparatus for testing RFID straps. Arrays of RFID straps in a roll-to-roll process are coupled to an array of test elements. RF programming and interrogation signals are frequency and time multiplexed to the RFID array. Return signals are detected to determine sensitivity and programmability parameters of the RFID straps. | 08-28-2008 |
