Abstract: The present invention provides a method and apparatus for non-invasive reduction of excessive fat tissue by externally applying radio frequency (RF) electromagnetic (EM) waves adjusted to specific fat cells absorption frequency and electromagnetic propagation mode. Based on the performed experiments described further, the method and working apparatus has been invented that reduces fat layers without any medication, non-invasively through the intact skin. The invented method and apparatus facilitates the safe fat removal, and may lead to reduction and eradication of obesity and obesity associated diseases.

Abstract: A multi-dimensional tracking sensor for tracking a moving transmitter with particular applications in virtual reality and other real time computer applications. The system employs an electro-magnetic (EM) tracking sensor having a small lightweight transmitter with a transmitting antenna located on the target to be tracked and an array receiver with several local stationary antenna elements. Multiple antenna elements of the array receiver lie on the perimeter of the measured space in positions determined by a self-calibration procedure. The proposed device calculates a cross correlation function between two signals at each receiving unit to determine a spatial position of the tracked element via a system of linear equations.

Abstract: The multi-dimensional tracking sensor especially for virtual reality and other real time computer applications. The disclosure describes an electro-magnetic (EM) tracking sensor that consists of a small lightweight transmitter with a transmitting antenna located on the target to be tracked and an array receiver with several local stationary antenna elements (FIG. 1). Multiple antenna elements of the array receiver lie on the perimeter of the measured space in positions determined by a self-calibration procedure. The proposed device calculates a cross correlation function between two signals at each receiving unit to determine a spatial position of the tracked element.
