Abstract: A simulation system includes a two-dimensional electrical grid installed in a floor or floor mat. Signals from boot mounted transmitters can be sensed via the grid to track boot locations in real-time during training exercises.

Abstract: Embodiments of the present invention include a coping apparatus and method of operation that automates the process of forming coped butt joints on strips of molding for placement on internal wall angles that alleviates at least some of the problems associated with the use of miter joints or time consuming hand or powered coping using conventional coping saws.

Abstract: A succinated triglyceride oil derived from maleating triglyceride oil from a plant or land animal is described for use as an emulsifying agent for metalworking fluids. The metalworking fluid would comprise water; as an emulsifier this succinated triglyceride, optionally further reacted with water, Group IA and IIA metals, ammonium hydroxide, various amines, alkanolamines, alkoxylated alkanolamines, and polyamines to form a modified emulsifier; and optionally an oil and other additives.

Abstract: This invention generally relates to a method and apparatus for locating a target depicted in a real-world image that has a slant angle and vantage point location that are only approximately known using a virtual or synthetic environment representative of the real-world terrain where the target is generally located; and more particularly, to such a method and apparatus wherein a set of views of the virtual environment is compared with the real-world image of the target location for matching the simulated view that most closely corresponds to the real-world view in order to correlate the real-world image of the target with the selected simulated view in order to correctly locate the target in the virtual environment and thereby determine the exact location of the target in the real-world

Abstract: A carrier-free pulverulent metalworking lubricant composition. In one preferred form, the composition contains at least two lubricant components one of which comprises a resin having a highly polar functional group the composition being formed by a method comprising the steps of: (a) forming a dry mixture of said particulate lubricant components, and (b) agglomerating said admixture to form agglomerated particles. The application of the composition as a metal working lubricant significantly reduces smoke and oily waste generation in hot forging operations by eliminating the use of oils or volatile organic compounds as carriers, while providing acceptable performance, cleanability, and sprayability.

Abstract: A protective device and method for the removal and disposal of spinal needles. The protective device is comprised of a needle pulling assembly upon which is slidably mounted an external housing. In operation, a needle to be removed from a patient is engaged in the needle cradle portion of the needle pulling assembly. The external housing is moved into contact with the patient's skin and the needle is withdrawn by pulling on the pulling rod portion of the needle pulling assembly in a direction away from the patient. The needle is withdrawn into the interior of the external housing, thereby covering the entire length of the needle. The pulling assembly is then locked into place and the entire assembly including the withdrawn needle can be disposed of, thereby avoiding the possibility of needle pricks by contaminated spinal needles.

Abstract: An apparatus for practicing tennis strokes, especially ground strokes, provides a support for holding a tennis ball at an initial predetermined position while allowing for a rotation of this ball about a horizontal axis of the support, this horizontal axis support being allowed to move along a predetermined ideal longitudinal axis and being biased to return to its initial position, whereby an irregular stroking of the tennis ball results in a less than ideal operation of the apparatus which is readily detected.
