Abstract: A system and method for transcutaneous energy transfer and/or charging in a transverse direction. An external power source having a primary coil being driven at a frequency selectable in the range between eight and twelve kiloHertz contained in a housing. An implantable medical device has componentry for providing a therapeutic output and a secondary coil operatively coupled to the componentry. The external power source is capable of providing energy to the implantable medical device when the primary coil of the external power source is placed in proximity of the secondary coil of the implantable medical device. The external power source has a lateral positional adjustment for the primary coil. The frequency of the external power source is frequency adjustable providing a frequency adjustment.

Abstract: In general, the invention is directed to a patient programmer for an implantable medical device. The patient programmer may include one or more of a variety of features that may enhance performance, support mobility and compactness, or promote patient convenience.

Abstract: In general, the invention is directed to a patient programmer for an implantable medical device. The patient programmer may include one or more of a variety of features that may enhance performance, support mobility and compactness, or promote patient convenience. For example, a patient programmer may include both an internal antenna for RF telemetry with an implantable medical device and a display. The patient programmer may include a processor or other control circuitry that selectively disables. i.e., turns off, the display during RF telemetry with the internal antenna to promote more reliable communication. The processor or control circuitry also may disable electronics associated with the display during a telemetry session. In this manner, the programmer can be configured to reduce the impact of electrical and electromagnetic noise on telemetry performance.

Abstract: The present invention relates to a universal contactor system for testing multiple size BGA devices on multiple types of testing equipment. The universal contactor system is comprised of a plurality of pogo pin which provide a connection between the BGA device to be tested and a DUT (Device Under Test) board. A contactor block having a plurality of apertures therethrough is used for holding the plurality of pogo pins. A guide plate having a center opening is coupled to the contactor block. The center opening in the guide plate is used for aligning the BGA device to be tested on the contactor block. The guide plate may be replaced with guide plates having a larger or smaller opening to align BGA devices of a larger or smaller size on the contactor block.

Abstract: A docking handle assembly is integrally formed from a single piece of metal for providing orthoganal movement of first and second levers. The docking handle has a set of three pivot points arranged in the form of a right triangle; and the main body portion has first and second handles extending outwardly therefrom in a mutually perpendicular arrangement, with each of the handles parallel to a different leg of the right triangle forming the pivot points. In operation, the pivot point located at the right angle of the triangle is pivotally attached to a support surface. The ends of first and second levers to be moved by the docking handle are pivotally attached to the other pivot points, respectively, for push-pull movement, as the main body portion is rotated by the handles about the pivot point attached to the underlying support surface.

Abstract: A passive acoustic target tracking system includes three microphones arrayed respectively at corners of an equilateral triangle for sensing acoustic energy emitted by a target, such as a heavy vehicle, and generating separate streams of analog signals representative of the acoustic energy sensed at the triangle corners. Hardware of the tracking system receives the separate streams of analog signals from the microphones and conditions and converts the separate streams of analog signals from analog to digital form and outputs the separate streams as digital signals. Software of the tracking system receives the separate streams of digital signals and provides the bearing to the target emitting the sensed acoustic energy. The software includes a minimum residual correlation algorithm and a two-state kalman filter algorithm.

Abstract: A target engagement system uses target motion analysis to determine a target engagement decision for ground targets, such as vehicles. The input to the engagement system is the target azimuth as a function of time. A detect algorithm issues and records a detect azimuth when confirmation is made that a valid target is being tracked and legitimate azimuth information is being provided. The engagement algorithm then begins and records the time intervals it takes for the target to cross two sectors, each covering 20.degree. and separate by 10.degree.. Thus, first time interval is measured from detect azimuth to 20.degree. after detect azimuth, and the second time interval is measured from 30.degree. after detect azimuth to 50.degree. after detect azimuth. When the first and second time intervals have been recorded, the ratio of the first time interval to the second time interval is calculated. If this ratio is greater than 2.0, then the target is estimated to be within range and is subsequently attacked.
