  • Publication number: 20170238033
    Abstract: A method and system to confirm co-location of multiple devices within a geographic area, while filtering spurious alarms, is provided. An example method comprises processing first GPS data obtained from a first GPS sensor and second GPS data obtained from a second GPS sensor. A sensing data evaluator compares a sensing error from the first GPS data and a sensing error from the second GPS data. Based on the result of the comparing, the sensing data evaluator determines whether the sensing errors are to be ignored. An approach where an alarm that otherwise would be generated is disabled or canceled may be termed as filtering spurious alarms.

  • Patent number: 9197059
    Abstract: A near field RF communicator has an inductive coupler to enable inductive coupling with a magnetic field of an RF signal; a rectifier to rectify an AC voltage derived from an RF signal inductively coupled to the inductive coupler; and a regulator to regulate a voltage derived from an RF signal inductively coupled to the inductive coupler, the regulator having a voltage-controlled impedance and a regulator controller to provide a control voltage for the voltage controlled impedance and to vary the control voltage in dependence upon a current flowing through the voltage controlled impedance. To prevent the voltage regulator from drawing excess current and energy from an RF field in which the communicator is present the voltage regulator is controlled to provide a chosen impedance characteristic.

  • Patent number: 9143199
    Abstract: An NFC communicator has an antenna circuit to enable inductive coupling, via an RF H field, of the NFC communicator and another near field RF communicator in near field range. The antenna circuit has an antenna element coupled in parallel with a first capacitor to form a parallel LC circuit. The antenna element has an antenna coil in series with a second capacitor to reduce the voltage to which circuitry of the NFC communicator is subjected by a received RF H field. Alternatively or additionally, receive circuitry of the NFC communicator may be coupled to only a proportion of the antenna coil to reduce the voltage to which circuitry of the NFC, communicator is subjected by a received RF H field.

  • Publication number: 20130337756
    Abstract: An apparatus and method is disclosed, to control NFC tag power dissipation. A first NFC device antenna harvests power for operation from a signal from another NFC device as a result of ambient magnetic fields present in the environment. The NFC device is configured with a regulator system in order to control the level of harvested power to prevent damage to the NFC device circuitry. The harvested power levels can exceed the ability of the regulator device to dissipate the additional power resulting in regulator damage or a reduction in the regulator lifetime. The power dissipation of the regulator can be monitored thermally, and the power dissipation controlled by reducing the regulation voltage accordingly. Various systems are presented to establish a cutoff threshold to the regulator power dissipation using thermal regulator feedback and/or antenna current monitoring.
