Abstract: An apparatus and method for preventing free flow through an infusion set utilizes an occluder disposed within the infusion set to selectively prevent flow therethrough. The occluder may be responsive to a pressure differential within the infusion set or may respond to compression of the infusion set. The occluder may also be configured to allow flow when the infusion set adjacent the occluder is moved sideways relative to the occluder or maintained at an angle relative to the occluder. When a pair of occluders are used in sequence, an in-line pump may be formed.

Abstract: A vacuum assisted scraper draws air from both in front of and behind the scraper blade to collect dust and debris as the scraper is used. The scraper keeps the work area clean and prevents dust buildup from hindering the use of the scraper.

Abstract: A universal air bubble detector allows for use with a variety of sizes and types of tubing. The detector maintains proper alignment of a sensor emitter and receiver with different sizes of tubing. The detector may be mounted on existing equipment or may be used to monitor a tubing at any position along the tubing, and may operate in a stand alone mode or in combination with existing equipment.

Abstract: A bullet trap is disclosed which is formed without intervening sidewalls to enable cross-shooting and the like with reduced risk or ricochet or damage to the bullet trap. Furthermore, the bullet trap can be configured in a variety of ways to eliminate the need for facing plates while providing a removable attachment mechanism, to enable repair on the trap, to reduce bullet adhesion to the trap and to provide improved containment of lead and improved access to the trap.

Abstract: A reusable ballistic door for use in the training of individuals such as police officers and military personnel. The door may be formed to have different weak spots, requiring different techniques to enter the door. The door may be quickly and inexpensively rebuilt for subsequent training. A reusable training door may also be used inside of a shoot house to provide realistic training scenarios.

Abstract: An improved kayak provides a rigid open cockpit hull with air chambers attached to the hull. The air chambers provide a generally convex shape for increased maneuverability and also provide cushioning against impact to reduce the risk of injury to the kayak pilot. The air chambers allow for an open cockpit kayak with an exterior surface having a similar shape as a conventional closed cockpit kayak, providing a similar level of maneuverability and allowing for completion of maneuvers such as rolling the kayak from an inverted position in the water.

Abstract: A prisoner seat security device includes a retractable strap which hooks or clasps onto a prisoner, preferably by a restraint device on the prisoner, such as hand-cuffs. As the prison seats in the seat, the strap retracts. The officer can then lock the retraction mechanism so that the strap will not extend and the prisoner is held in place. When it is desired for the prisoner to get out of the chair, the lock is released, allowing the prisoner to stand the strap to be disconnected.

Abstract: A pillow is provided for the treatment of deformational plagiocephaly. The pillow preferably has arms which define a void with varying diameters to facilitate holding an infant's head to cause reshaping of the posterior of the skull. An anchoring mechanism may also be included to hold the pillow in place.

Abstract: An enterostomy device for providing fluids and nutrients through a stoma formed through the abdominal wall of a patient is described. The enterostomy device, which may be configured as either a gastrostomy device or a jejunostomy device, comprises a low-profile retaining member which is configured to be unobtrusively positioned within the stomach or the intestine, and which is configured to provide sufficient surface area for contacting the stomach or intestine to prevent unintentional removal or release of the enterostomy device from the patient. The enterostomy device is also structured with a low-profile port hub for facilitating the inflation of the retaining member and feeding and venting through the stoma.

Abstract: A combination of a metal and Sn may be used as a solvent material for bulk crystallization and sintering of single crystal diamond to form a biocompatible and corrosion-resistant biomedical device.

Abstract: Diamond bearings and bearing components are disclosed. Some embodiments of the bearings and bearing components include polycrystalline diamond compacts sintered under high pressure and high temperature to create a diamond table chemically and mechanically bonded to a substrate, the diamond table presenting a durable and thermally stable load bearing and articulation surface.

Abstract: A modular ballistic wall is disclosed for use in shoot houses and the like. The modular ballistic wall can be formed from metal plates having key-holes formed therein which are held together by facing and backing strips. Additionally, the modular ballistic wall is preferably formed so that the bolts used to hold the facing and backing strips to the metal plates do not directly secure a bullet containment frame to the facing and/or backing strips, to thereby prevent damage to the bullet containment frame from weakening the joint formed by the metal plates and the facing and backing strips.

Abstract: Use of Ti and Nb cemented in TiC in prosthetic joints, such as prosthetic joint components made from sintered superhard materials.

Abstract: A drop target includes a first target seen by a shooter and a second target concealed behind the first target. When the shooter hits the second target, the first target moves, thereby representing that the shooter as hit a desired “kill zone” and should cease shooting.
