    Abstract: A method for producing an output bit stream for a first signal of a first carrier frequency by a security module involves the security module receiving an input signal comprising the first signal and a second signal of a second carrier frequency. A mixed signal is formed which has the first signal at the first carrier frequency, the second signal at the second carrier frequency, and a mixed product at an intermediate frequency. The mixed product is demodulated by a second nonlinear component to output a second baseband signal for generating a second bit stream relating to the first signal in the mixed product. The output logic produces the output bit stream for the first signal, and selects either the first bit stream or the second bit stream as the output bit stream for the first signal.

    Abstract: Determining movement of a Radio Frequency Identification (RFID) tag first establishes a phase difference/frequency model comprising a set of phase-wrapped local rates-of-change and an intercept point. RFID tag readings are then made to measure phase differences between the interrogation signal and the tag response at different frequencies. A correlation is determined between the measured phase differences versus frequency and the phase-wrapped local phase rates-of-change of the phase difference/frequency model. If the correlation is better than or equal to a predetermined limit, the tag is stationary, or if the correlation is worse than the predetermined limit, the tag is moving.

  • Patent number: 8884743
    Abstract: An RFID memory device includes two arrays of resonant members. A first array extends in a first member direction and a second array extends in a second member direction. The device includes one or more elements for transforming energy associated with vibration of the resonant members into a change in impedance of an electrical equivalent circuit of the memory device. The magnitude of impedance change caused by resonance of the first resonant members is maximized at a different magnetic field direction to that at which the magnitude of the impedance change caused by resonance of the second resonant members is maximized. Thus, different data may be encoded on each array and separately read. The resonant members may form part of a common electrical conductor that forms a coupling element for coupling with an applied excitation signal and causing vibration of the resonant members.

  • Patent number: 8810403
    Abstract: When multiple readers for RF transponders have to be placed in close proximity, such as in adjacent lanes of a highway toll barrier, they can be set to operate at different frequencies. When signals from two adjacent ones of the readers interfere, the resulting signal includes interference terms whose frequencies equal the sum of the reader frequencies and the difference between the reader frequencies. To remove such interference terms while passing the desired terms, a tag includes a low-pass or other frequency-selective filter.

  • Patent number: 8797162
    Abstract: A detection unit positioned on a package includes a magnet, a first magnetic switch, a second magnetic switch, a processor, and a clock. The first magnetic switch outputs a first control signal or a second control signal according to magnetic flux density of the magnet. The second magnetic switch outputs a third control signal or a fourth control signal according to the magnetic flux density of the magnet. The first control signal is the same as the third control signal; the second control signal is the same as the fourth control signal. When the processor receives the first control signal and the third control signal at the same time, the processor reads a first real-time clock (RTC) signal from the clock. When the processor receives the second control signal and the fourth control signal at the same time, the processor reads a second RTC signal from the clock.
