  • Patent number: 10083386
    Abstract: An object is disclosed, the object (100) comprising a body comprising an antenna; and an integrated circuit embedded in the body and electrically connected to the antenna for receiving and transmitting wireless signals. The integrated circuit receives wireless signals at first and second different frequencies, waits until a command is received at the first frequency from a first reader device before transmitting a first signal and, upon detection of a signal at a second frequency different to the first frequency from a second reader device (201), transmits a second signal without waiting until a command is received.

  • Patent number: 9454471
    Abstract: An electronic counter is provided having a sequence of memory cells and increment logic. Each memory cell of the sequence is non-volatile and supports a one state and a zero state. The one state can also be referred to as a ‘programmed state’, the zero state as an ‘erased state’. The counter is configured to represent at least part of a current counting-state of the counter as a pattern of one and zero states in the memory cells of the sequence of memory cells, and increment logic configured to advance the pattern of one and zero states to a next pattern to represent an increment of the counter.

  • Patent number: 9112941
    Abstract: The invention relates to an RFID transponder device configured for responding to a request of an RFID reader device, by sending a response (UID) comprising information for encoding a feature set of the RFID transponder device. The invention further relates to an RFID reader device and to an RFID system comprising such RFID transponder device and such RFID reader device. The invention also relates to various methods. The invention provides an RFID system, which is more flexible towards introducing new RFID transponder devices that are newly introduced to the market. The invention enables the introduction of such new devices using a sub-set of a prior defined feature set without requiring updating of the look-up tables of the RFID reader devices that are already on the market. This is achieved by directly encoding the feature set of the RFID transponder device in the response, such as in a unique identifier of the device.

  • Patent number: 8441340
    Abstract: A contactless tag reader device comprises upper and lower electrodes which together define a tag location zone between them in which multiple tags can be placed. The lower electrode and the upper electrode are offset from each other such that they substantially do not overlap. This structure is used to sandwich tags vertically between two horizontally (laterally) offset reader electrodes. This enables power coupling and data transfer using capacitive coupling.

  • Patent number: 8253540
    Abstract: A method of reading data (DAT1 . . . DAT4) from transponders (T1 . . . T4) by means of a reader device (RD) during a number (N) of time slots (TS) is disclosed, wherein the seizure of said time slots (TS) by the transponders (T1 . . . T4) is observed in both the reader device (RD) and the transponders (T1 . . . T4). A reorganization (REORG) is performed in dependence on said seizure, wherein both the reader device (RD) and the transponders (T1 . . . T4) choose a new number (N) of time slots (TS). In addition, the transponders (T1 . . . T4) select one of the new time slots (TS) in which to send data (DAT1 . . . DAT4) back to the reader device (RD) so as to adapt the system's capacity to the real demands. Preferably, said reorganization (REORG) takes place without communication between the reader device (RD) and the transponders (T1 . . . T4). The invention further relates to a transponder (T1 . . . T4) and to a reader device (RD) for implementing the inventive method.
