Abstract: Methods and apparatus for an imaging system are provided. The imaging system includes a gantry having a stationary member coupled to a rotating member. The rotating member has an opened area proximate an axis about which the rotating member rotates. An x-ray source provided on the rotating member. An x-ray detector may be disposed on the rotating member and configured to receive x-rays from the x-ray source. A rotary transformer having circumferentially disposed primary and secondary windings may form part of a contactless power transfer system that rotates the rotatable portion of the gantry at very high speeds, the primary winding being disposed on the stationary member and the secondary winding being disposed on the rotating member.

Abstract: A method and apparatus are provided for minimizing output pulse jitters in a phase locked loop. The method includes pre-setting the digital phase locked loop to a desired frequency, locking the digital phase locked loop to the desired frequency to generate an output signal, and filtering the output signal of the digital phase locked loop to maintain undesirable jitter to an acceptable range. In one embodiment, the apparatus is a medical imaging device. In another embodiment, the apparatus is a baggage imaging device.

Abstract: A data transmission system that includes a transmitter; a receiver; and a magnetically coupled rotary transformer having a first portion and a second portion in moveable relationship with one another. The transmitter is electrically and mechanically coupled to the first portion of the rotary transformer, and the receiver is electrically and mechanically coupled to the second portion of the rotary transformer. The transmitter and the receiver are configured to wirelessly communicate data across the rotary transformer while the first and the second portions of the rotary transformer are in relative rotary motion.
