Abstract: An eyeglass frame sizing system includes a frame member, a pair of adjustable rims supported by the frame member, each rim including an indicator for indicating a center of the rim, an adjustable nosepiece supported by the frame member, a pair of adjustable temples each supported by one of the pair of rims and a plurality of sensors for detecting positions of the pair of adjustable rims, the pair of adjustable temples and the adjustable nosepiece.

Abstract: A method is provided for controlling a resonant circuit (1) of an ICPT system. The resonant circuit has a controlled variable reactance (2), and a predetermined perturbation is introduced in the magnitude of variable reactance. The change in a property of the resonant circuit in response to the perturbation is sensed, and the variable reactance is varied to alter the resonant frequency of the circuit in response to the sensed change.

Abstract: A module for use in a communications network in which a plurality of signals are transmitted between respective first and second nodes, the module having an engine for receiving the plurality of signals over the network, for extracting protocol data therefrom and for providing the extracted protocol data to an analyzer; and a processor for controlling operation of the engine and analyzer. The invention also provides an apparatus for generating communications, systems including the module and/or the apparatus, and corresponding methods.

Abstract: An Inductive Power Transfer (IPT) pick-up apparatus includes a magnetically permeable core, a first coil, being wound about the core so as to be inductive coupled therewith such that a current induced in the first coil is most sensitive to a first directional component of magnetic flux and a second coil, being wound about the core so as to be inductively coupled therewith such that a current induced in the second coil is most sensitive to a second directional component of magnetic flux. The first directional component is substantially orthogonal to the second directional component.
