A regulation system for a permanent magnet generator for generating electrical power and for supplying the electrical power to a load comprises a switching circuit connected between the permanent magnet generator and the load, the switching circuit being capable of regulating the electrical power being supplied to the load and a control circuit connected to the switching circuit, the control circuit for determining the amount of electrical power being supplied by the permanent magnet generator and for controlling operation of the switching circuit to regulate the electrical power being supplied to the load.

A telephone interface system for the transmission and reproduction of an audio performance, particularly a musical performance, at separate locations utilizing an amplitude modulated carrier frequency is disclosed. The system serves to both transmit a performance at one instant location to one or more remote locations and to receive and reproduce a similar performance from the remote location(s) transmitted to the instant location. The performer(s) at a first location each hear the audio output of the performance(s) at the other location(s) as though such other performer(s) were actually present at the first location and vice versa.

A controller controls the running speed of a variable speed motor of the type which runs at a speed related to the duty cycle of a pulse width modulated drive voltage applied to it and to the load being applied. The controller includes a setting switch for setting the motor running speed and a device for measuring the load being applied to the motor. Also included is a data storage for storing data representing a plurality of different pulse width modulation duty cycles for driving the motor at various desired motor running speeds and with various loads being applied to the motor. A processor is operatively connected to the setting switch, the load measuring device and the data storage for generating signals representing a particular duty cycle corresponding to a desired running speed setting and applied load to result in the desired motor speed. The processor generates these signals at a predetermined time interval to reach and maintain the desired motor speed. A voltage applying device is provided for applying the pulse width modulated voltage having the particular duty cycle to the motor.
