Abstract: The invention is related to a pair-assignment device (100) comprising a sensing-node position ascertainment unit (102) configured to ascertain position information (P.I.) pertaining to respective positions of external RF-sensing nodes (104,106) with respect to a predefined sensing volume (108) of a RF context-sensing arrangement and a pair-assigning unit (110) configured to assign, using the ascertained position information, at least one transmitter-receiver pair among the individual RF-sensing nodes of the RF context-sensing arrangement to perform a RF context-sensing function, to assign to the RF sensing nodes of the given transmitter-receiver pair a transmitter role (Tx) and a receiver role (Rx), respectively. The pair-assignment device then provides pair information indicative of the at least one assigned transmitter-receiver pair and the assigned transmitter and receiver roles and thus enables an increase of tolerance of the RF context-sensing arrangement against changes in the position of movable objects.

Abstract: A resonant inverter has a switch network from which a phase signal is provided representing the phase of the switching signal. A resonant tank circuit is coupled to the first switch network output and provides a feedback signal comprising a resonance voltage across a circuit element of the resonant tank circuit. A reference current to be drawn from the input node is set and a reference phase is set based on the reference current. The switching signal for the switch network is controlled based on a phase difference between the resonance voltage and the phase signal, and based on the reference phase. This resonant inverter employs a phase modulation scheme as the control scheme for the switch network of a resonant inverter. This approach is suited for high and very high frequency operation of resonant converters, for example up to tens of MHz.
