A drive system for a three phase brushless AC motor is arranged to optimize the transistor switching pattern to improve power output whilst allowing current measurement in all of the phases using a single sensor. This is achieved by defining voltage demand vectors x where more than two states are required to meet a minimum state time requirement determined by the single sensor method, and calculating three or more state vectors which produce the demanded vector x whilst still allowing single current sensing. Various methods of optimising the PWM pattern so as to give maximum output whilst using single current sensing are also disclosed.

A permanent magnet chuck for holding or lifting workpieces is formed of two overlying / underlying flat surfaced chuck layers having a common center of rotation. In each chuck layer an even number of permanent magnet plates radiate from the center of rotation at equal angles with blocks of magnetically soft material between them. The permanent magnet plates are magnetized so that the interposed soft magnet blocks exhibit alternating N-S magnetic polarities. The organization of the permanent magnet plates and soft magnet bodies is matching and complementary so that relative rotation of the chuck layers magnetically activates or de-activates the chuck.

A transceiver at one end of a variable data rate, time division duplex (TDD), adaptively modulated, point-to-point radio link transmits one or more pulses at different amplitude levels during a settling period of the transceiver's power amplifier. The highest level of the pulses is set to a level higher than the mean level of an OFDM symbol in a transmit burst immediately following the transmitted pulses, and is incrementally increased with each successive burst. A second transceiver at the opposite end of the link receives the transmitted pulses as time domain samples, normalizes the samples, and performs a cross correlation of the samples corresponding to the received pulses. When the cross correlation indicates that the power amplifier is operating at a maximal power level with regard to the amplifier linearity and the modulation mode and coding rate currently in use, the incremental increase of the transmission power ceases.

An electromagnetic pump has a supply section and a magnetic force pumping section wherein flow of an electrically conductive material through the supply section is opposite to the flow of the material in the magnetic force pumping section in some examples. Multiple coils surround the supply and magnetic force pumping sections. Current flowing through the multiple coils creates magnetic fields that magnetically couple with a magnetic material disposed between the supply and magnetic force pumping sections so that the fields penetrate the electrically conductive material in the magnetic force pumping section substantially perpendicular to the desired flow direction which maximizes the magnitudes of magnetic forces applied to the electrically conductive material. Alternatively the electromagnetic pump has a supply section and a magnetic force pumping section wherein flow of an electrically conductive material through the supply section is in the same direction as the flow of the material in the magnetic force pumping section.
