Magnetic Therapy Device
First Claim
1. A magnetic therapy device comprising:
- a housing;
a disk comprising a plurality of magnets thereon, the disk being mounted inside the housing and configured to rotate within the housing;
a tachometer configured to monitor a magnetic field generated by the plurality of magnets and provide a frequency signal to a microprocessor based on the monitored magnetic field;
the microprocessor configured to provide a control signal to the driver integrated circuit based on the frequency signal, the microprocessor being programmed to provide the control signal to maintain a constant speed of rotation of the disk based on the frequency signal;
the driver integrated circuit configured to provide a current to a plurality of coils based on the control signal; and
the plurality of coils configured to generate, based on the current received from the driver integrated circuit, a magnetic field which will generate a force on the plurality of magnets and thereby cause the disk to rotate.

Abstract
According to an example embodiment, a magnetic therapy device may include a housing, a disk, a tachometer, a microprocessor, a driver integrated circuit, and a plurality of coils. The disk may include a plurality of magnets thereon, the disk being mounted inside the housing and configured to rotate within the housing. The tachometer may be configured to monitor a magnetic field generated by the plurality of magnets and provide a frequency signal to a microprocessor based on the monitored magnetic field. The microprocessor may be configured to provide a control signal to the driver integrated circuit based on the frequency signal, the microprocessor being programmed to provide the control signal to maintain a constant speed of rotation of the disk based on the frequency signal. The driver integrated circuit may be configured to provide a current to a plurality of coils based on the control signal. The plurality of coils may be configured to generate, based on the current received from the driver integrated circuit, a magnetic field which will generate a force on the plurality of magnets and thereby cause the disk to rotate.

19. A magnetic therapy device comprising:
-
a housing; a motor mounted on the housing and configured to; cause a disk to spin when the motor is active; and receive power from a battery; the disk mounted on the motor, the disk having a plurality of magnets mounted on the disk; a receiver coil configured to receive power from a magnetic field and transfer the power to the battery; a circuit configured to; cause the motor to become active for a finite duration of time and then become inactive before the battery has been drained of power; and cause the motor to become active when an inductive probe is taken away from the receiver coil.
