Abstract: Communications apparatus has a short range wireless radio frequency communicator (1301a) capable of at least one of seeking to initiate short range communication by transmitting an RF signal and of responding to such initiation so that communication between two short range wireless radio frequency communicators occurs when an antenna of a short range wireless radio frequency communicator seeking to initiate communication by transmitting an RF signal is in range of or comes into range of the antenna of another short range wireless radio frequency communicator responsive to such initiation so that the magnetic field of the RF signal transmitted by the short range wireless radio frequency communicator seeking to initiate communication is inductively coupled to the antenna of the short range wireless radio frequency communicator responsive to such initiation to enable communication of at least one of power and data between the short range wireless radio frequency communicators.

Abstract: A Near Field Communication (NFC) device has a short range wireless radio frequency communicator capable of seeking to initiate short range communication by transmitting an RF signal and of responding to such initiation so that communication between two short range wireless radio frequency communicators occurs when in range. The NFC device also has a high data rate data communicator for communicating directly with another high data rate data communicator to receive and transmit data when the short range wireless radio frequency communicator has communicated with another in-range short range wireless radio frequency communicator.

Abstract: A NFC communicator or NFC communications enabled device has a data store to store data, a coupler to couple inductively with the magnetic field of a radio frequency signal and a signal generator to supply a radio frequency signal to the coupler. A modulator is provided to modulate a radio frequency signal in accordance with data and a demodulator is provided to extract data from a modulated radio frequency signal inductively coupled to the coupler. A controller enables the NFC communicator or NFC communications enabled device both to initiate near field radio frequency communication with another near field RF communicator and to respond to near field radio frequency communication initiated by another near field RF communicator. The NFC communicator or NFC communications enabled device also has a power deriver that derives power from a radio frequency signal inductively coupled to the coupler to charge a chargeable power supply.

Abstract: A detectable component has a first inductive coupler (L;M) adapted to couple inductively to a second inductive coupler (L1) of a detection apparatus when the detectable component is in range of or coupled to the detection apparatus. The first inductive coupler has a resistive component (M) with a resistance that varies with magnetic field to cause modulation of a carrier signal supplied to the second inductive coupler of the detection apparatus, the detectable component having a characteristic signature that enables the detectable component to be distinguished by the detection apparatus from other such detectable components having different characteristic signatures.
