Abstract

Various example embodiments are disclosed. According to one example embodiment, an apparatus may include a voltage source coupled to a motor via a diode, the diode coupled to the motor and the voltage source, a rechargeable battery, and a motor. The diode may be configured to allow current to flow from the voltage source to the motor. The motor may be configured to spin a disk upon which a plurality of magnets are mounted. The apparatus may be configured to recharge the rechargeable battery with the voltage source and to enable the rechargeable battery to supply power to the motor when a voltage of the voltage source drops below a threshold voltage level.

Claims

1. A magnetic therapy device comprising:

a current inducing circuit configured to convert a first magnetic field into a direct current (DC) voltage;

a battery charging circuit configured to charge a rechargeable battery based on the DC voltage, and to supply power to a motor and to a microprocessor based on the rechargeable battery;

the microprocessor configured to control a plurality of visual indicators and to control the motor;

the visual indicators configured to emit light outside the magnetic therapy device;

the motor configured to generate a second magnetic field by spinning a disk upon which is mounted a plurality of magnets; and

a housing which encloses the battery charging circuit, the microprocessor, and the motor, and in which are mounted the current inducing circuit and the visual indicators.

2. The magnetic therapy device of claim 1, wherein the current inducing circuit comprises:

a secondary coil configured to induce a current from the first magnetic field;

a delay switch coupled to the secondary coil; and

an output node coupled to the delay switch and to the battery charging circuit.

3. The magnetic therapy device of claim 2, wherein:

the housing includes an aperture; and

the secondary coil surrounds the aperture.

4. The magnetic therapy device of claim 1, wherein the housing is disk-shaped.

5. The magnetic therapy device of claim 1, wherein the housing includes no electrical contacts on an outside surface of the housing.

6. The magnetic therapy device of claim 1, wherein the housing is waterproof.
