ABSTRACT:
A system is provided for communicating energy from one device, such as the rotating frame of a CT scanner, to another device, such as the fixed frame of a CT scanner, where the two devices are capable of movement relative to one another. A plurality of transmitting elements are mounted on one of the devices and a plurality of receiving elements are mounted on the other device, spaced equidistantly around the perimeters of the respective devices. The number of receiving elements is one different than the number of transmitting elements, and the range of operation between a transmitting element and a receiving element is sufficient to assure an operative relationship between at least one of the transmitting elements and one of the receiving elements upon the relative movement of the devices.
