Abstract: A display retraction assembly for a multi-display visualization device is provided comprising a first track in a first vertical plane, a second track in a second vertical plane offset from the first track, a display support member operably connected to the first track and second track and a display connected to the display support member wherein the display is movable simultaneously with the display support member along the first track and second track.

Abstract: A mat for learning, teaching, and performing yoga is provided in which the upper surface of the mat includes visually discernable floor-contacting body part markings. Sets of the markings can be used by yoga practitioners to facilitate proper positioning for one or more yoga poses. In another aspect of the invention, mats can be made for practitioners of different sizes and abilities by varying the spacing of the sets of markings for the poses. Further, an image of the mat can be represented on another medium, such as a card, poster, or video, on which a pose is depicted and the representations of the markings of the mat for that pose can be highlighted.

Abstract: The invention, as embodied herein, comprises an improved portable maritime scoring and simulation system that comprises three or more buoys that are deployed in an area of water selected for maritime combat training. Attached to each buoy are a global positioning system receiver, an RF radio system, an acoustic analysis system, and a microprocessor. The acoustic analysis system is designed to capture an acoustic signature of ordnance impacting the water with predetermined characteristics. The system includes an RF radio repeater system linked to a system controller to control and monitor the elements of the system. In operation, when an acoustic signature is captured by the acoustic analysis system, the RF radio system, in one embodiment, transmits the time of the capture along with the GPS location of the buoy to the RF radio repeater system linked to the system controller.

Abstract: A golf swing training device for developing the memory of a proper golf swing for every golf club a golfer uses in their game so that each swing is naturally and consistently repeated when they engage in actual play. The golf swing training device includes a base for receiving a golfer's front foot, at least one pivot arm having a first end pivotally mounted to the base and a second end opposite the first end, a biasing mechanism for biasing the pivot arm to a first position with respect to vertical, and an engagement member disposed on the second end of the pivot arm for engaging the golfer's hip area when they position their front foot on the base to address the golf ball. Engagement of the engagement member displaces the pivot arm to a second position with respect to vertical and creates a constant pressure force against the golfer's hip area which ingrains the golfer's mind with the memory of the proper, pace and body position for performing each golf swing.

Abstract: A system for simulating own ship sensor outputs for submarine trainers is ovided. The system comprises of five personal computer systems operating together. These computers are interconnected such that the individual computers can exchange data and function as one integrated unit. The system provides sensor output to an external trainer through multiple STANAG, NTDS, DIGITAL.TM. I/O, and DIGITAL-SYNCHRO.TM. I/O cards. The system also accepts trainer inputs on these lines. Software modules on the personal computer systems allow the operator to configure and monitor the sensor systems as well as providing processing of inputs received at multiple sources to generate a coherent output signal.

Abstract: In a method for offering a dummy target which simulates the target signature of a subject, such as land craft, aircraft or water craft, to an imaging, radiation-sensitive homing head such as an infrared homing head, a number of active masses are deployed at respective spatial positions, with each mass simulating a portion of the target signature of the subject by emitting spectrally differentiated radiation in the sensitivity range of the homing head. The active masses are deployed at positions to produce a three-dimensional dummy target in which sources of radiation to which the homing head is sensitive are positioned in a manner which mimics the subject.

Abstract: This invention relates to a target which is towed by an aircraft to simulate the approach of an aircraft, missile or similar threat to a Defence System, to provide realistic practice for the Defence System. In accordance with this invention there is provided a target that is connected by a cable to a tow aircraft and towed by the aircraft toward a Defence System at a low approach altitude. The target has flight surfaces that, in combination with the mass of the target, cause the target to be towed at a substantially lower altitude than the tow aircraft. This allows direct ground or sea skimming approach by the target as the tow aircraft overflys the Defence System. The target is provided with a cable release means that releases the target at a predetermined safety range, whereupon the cable rises to a free streaming height and clears the Defence System.
