A near-field magnetic induction system includes a metallic structure, an amorphous metal barrier and a near-field magnetic induction device. The device includes an antenna coupled to the amorphous metal barrier and a circuit electrically coupled to the antenna. In use, the antenna is separated from the metallic structure by the amorphous metal barrier. The amorphous metal barrier may be integrated with the near-field magnetic induction device or with the metallic structure. Inductive coupling with the near-field magnetic induction device may be used, for example, in communication or energy transfer applications such as RFID tags and inductive chargers.

Method and apparatus for inductive coupling utilizing an amorphous metal barrier

An electronic component in accordance with the invention includes a body, such as a base, having a high magnetic permeability material applied to an external surface thereof and a wire winding wound about at least a portion of the high magnetic permeability material. In a preferred form, the body is made of a non-conducting material, such as ceramic or plastic, and the high magnetic permeability material is made of a magnetic material such as ferrite or a metallic glass alloy (i.e., an amorphous metal). The component further includes a spacer for separating the wire winding from the high magnetic permeability material in order to prevent the amorphous metal from damaging the wire winding. The resulting electronic component is capable of sensing magnetic fields and may be used in a variety of circuits such as compasses and magnetometers.

Sensor coil and method of manufacturing same

A method and apparatus for recovering a data symbol from a communication signal in which the communication signal is processed to produce a baseband waveform that is then sampled to obtain a channel sequence. The channel sequence is decoded to obtain an estimate of the data symbol together with a measure of the reliability of the data symbol. The processing of the communication signal is adjusted dependent upon the measure of the reliability of the data symbol. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Communication system control using reliability data

An amplifier for amplifying an input signal in a frequency band, has a quadrature signal divider for dividing the input signal into first and second components. The first component is amplified in a first transistor amplifier having a first frequency response to produce a first amplified component. The second component is amplified in second transistor amplifier having a second frequency response, different to the first frequency response, to produce a second amplified component. The first and second amplified components are combined in a quadrature signal combiner to produce an amplified input signal. The frequency response of the amplifier is related to the sum of the first frequency response and second frequency response.

High frequency amplifier

A low profile surface mountable component having a strengthened structure in accordance with the disclosure set forth herein comprises an elongated core having first and second ends and first and second supports for supporting the core and for absorbing forces experienced by the component that are attributable to mechanical shock. Each of the supports defines a receptacle for receiving one of the core's first and second ends. The component further comprises means between the ends of the core and the supports for permitting movement of the core with respect to the supports, and has metalized pads provided on the supports for electrically connecting and mounting the support to the printed circuit board. At least one wire is wound about a portion of the core and has its ends electrically connected to the metalized pads of the supports.
