摘要： 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.

摘要： In accordance with one embodiment, a contactless power transfer system is provided that comprises a stationary member including a power input configured to receive power at first voltage from a power supply. The system further includes a rotating member rotatably coupled to the stationary member and a rotary transformer. The rotary transformer has primary and secondary sides, with the primary side being disposed on the stationary member. The primary side has a primary winding that receives power at the first voltage from the power input. The secondary side is disposed on the rotating member and produces power at a second voltage. The secondary side has a rotating core and separate secondary sub-windings, each of which has forward and return paths that are circumferentially disposed about the rotating core. The forward and return paths of each of the sub-windings rotate proximate to, and are disposed a substantially equal distance from, the primary winding disposed on the stationary member.
