Abstract: A treatment device for providing a magnetic treatment and a radiofrequency treatment to a body area of a patient. The device includes an energy storage device for storing electric energy, a magnetic field generating device, and a switching device to discharge the electrical energy from the energy storage device to the magnetic field generating device, such that a time-varying magnetic field is generated and provides muscle contraction to a muscle in the body area of the patient. The time-varying magnetic field may have a magnetic field density in a range of 0.1 Tesla to 7 Tesla and a repetition rate in a range of 0.1 Hz to 700 Hz. The device may also include a radiofrequency electrode to generate radiofrequency waves to heat a tissue in the body of the patient. A body of the radiofrequency electrode may include a plurality of openings in a range of 5 to 1000 openings.

Abstract: A digital phase to digital sine and cosine amplitude translator generates sine and cosine outputs from an input angle word, which is decomposed into the most significant bits (MSBs) and the least significant bits (LSBs), and the octant number of the angle is identified by the octant identifier bits. Radix-4 multiplier/adder circuits improve the efficiency of multiplication/addition computations. An incrementor and a decrementor are used for sine and cosine MSB computations, respectively, to further save the computer memory and logic. In a preferred embodiment, the MSBs of the sine and cosine outputs for all octants are generated based upon the octant number of the input angle, and the LSBs of the outputs are generated by trigonometric approximations and octant selection, thereby resulting in a savings in computer memory and logic.
