  • Patent number: 9805227
    Abstract: Methods and apparatuses for selecting a subset of RFID tags are provided in some embodiments. These methods and apparatuses utilize the susceptibility to light by persistent nodes found in passive tags. Light can be used to intentionally reduce persistence times in a particular subset tags or even an individual tag. Then, persistent nodes can be used as a selection criterion to distinguish previously illuminated tags from non-illuminated tags. In other embodiments, a power circuit receives a RF input source and generates a direct current (DC) output voltage. The circuit includes a bias circuit to supply a gate to source bias, which is independent of the DC output voltage. The circuit further includes a voltage multiplier circuit that is coupled to the bias circuit. The voltage multiplier circuit has MOS transistors with one transistor to receive the gate to source bias.

  • Publication number: 20080186185
    Abstract: Methods and apparatuses for the protection of radio frequency identification (RFID) devices are described. In one aspect, a static dissipative material is applied to a web of antenna structures. A coating of the static dissipative material is applied continuously across a plurality of antenna structures of a roll of the web material. An RFID integrated circuit (IC) is attached to the web of antenna structures with the dissipative coating, then subsequently tested on the roll. Additional processing is performed to the RFID tag to produce an RFID label.

  • Patent number: 6590346
    Abstract: Method and apparatus for electrical devices. An electronic assembly comprises at least one object having a first electrical circuitry therein. The object is created and separated from a host substrate. The assembly further comprises a receiving substrate having at least one recess. A bottom conducting layer is deposited over the receiving substrate and the recess. The object is then coupled to the receiving substrate such that the object is deposited on the bottom conducting layer and recessed within the first recess and below a surface of the receiving substrate. An insulation layer having a plurality of vias is disposed over the receiving substrate to insulate the bottom conducting layer and the object. A top conducting is deposited over the insulation layer and is making electrical interconnections to the bottom conducting layer and the object through the vias.
