  • Patent number: 9666043
    Abstract: A detection system for use with an article, the system including a frangible fastener having a shaft structured to be attached to the article; and a radio frequency communication circuit formed on or in the fastener, the radio frequency communication circuit including an antenna formed on or in the article; and a resonator component formed on or in the fastener shaft and structured to be coupled to the antenna through inductance when the fastener is attached to the article and the antenna is energized, the resonator element further structured to fail to function when the fastener shaft is broken.

  • Patent number: 9483671
    Abstract: 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.

  • Patent number: 9406012
    Abstract: The circuitry introduced in this invention selectively slows down the functioning of an electronic circuit maintaining a particular state for a prolonged period of time. This circuitry is used not only to achieve the desired effect in maintaining security from electronic thieves trying to circumvent codes but also in other applications such as enabling a circuit to continue to function in the event of a brief loss of power. For example, in an RFID system, if a reader is frequency hopping, a tag loses power for as long as about 400 milliseconds when the reader changes to other frequencies. In a preferred embodiment, the disclosed circuitry is used in conjunction with a destruct sequence.

  • Publication number: 20150199696
    Abstract: A signal is received from each of a first RFID tag corresponding to a first item and a second RFID tag corresponding to a second item. It is determined that the first item was purchased from the retail environment. A relative movement of the second item to the first item within the retail environment is determined. An item interest in the second item relative to the first item is determined based on the relative movement. A purchase analysis of the second item relative to the first item based on the item interest is provided.

  • Patent number: 8922375
    Abstract: 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.
