    • An apparatus and method for treating sleep apnea includes a bilevel flow generator having an alternating current (AC) synchronous motor coupled to a low inertia centrifugal rotor/impeller. The process of acceleration and deceleration of the rotor involves moving from frequency A, amplitude A to frequency B, amplitude B in an optimal linear fashion using the so-called Bresenham algorithm. This is coupled with a tuned increase of the amplitude during the acceleration process which will produce the acceleration using minimum current allowing the use of smaller power supplies. During deceleration the process is accomplished in reverse fashion using a tuned decrease of the amplitude coupled with a special shunt circuit to prevent power supply voltage changes. These changes in amplitude overlay a current feedback mechanism used to prevent loss of synchronization of the motor by changing amplitude. Speed changes can also be timed so as to prevent desynchronization.

    • A controller for DC motor is provided with an FET (206) which is connected between one end of a motor (201) and the positive electrode of a battery EB, a diode (203) through which the electric current having flown through the motor (201) is passed when the switch (220) of the battery EB is turned off, a means for measuring the current flowing through the motor (201) which comprises a shunt resistor (203a), a differential amplifier (203b), and a low-pass filter (203c), and a controller (250) which PWM-controls the turn-on/off of the FET (206) so that the measured value of the current flowing through the motor (201) is coincident with a target value. The controller (250) sets a very small value as the target value when the switch (220) of the battery EB is turned off and supplies the very small current to the motor (201). Therefore, the FET which drives the motor of a bicycle with auxiliary motor is protected at a low cost without adding any extra component.

    • A home positioning system for use in combination with a DC motor driven system, wherein the DC motor (20) is provided with a pulsed input voltage signal to effectively decelerate the motor (20). This pulsed input voltage mode is activated at a predetermined time so that the velocity of the system is reduced as an element (17) approaches a predetermined home position in order to accurately stop the system and precisely locate the element (17) at the home position.
