Abstract: A method of fabricating a semiconductor-on-insulator semiconductor substrate is disclosed that includes providing first and second semiconductor substrates. Either oxygen or nitrogen is introduced into a region adjacent the surface of the first semiconductor substrate and a rare earth and hydrogen are implanted at different energy levels into the second semiconductor substrate to produce a rare earth rich region adjacent the surface and a hydrogen layer spaced from the surface. The surface of the first semiconductor substrate is bonded to the surface of the second semiconductor substrate in a process that includes annealing to react either the oxygen or the nitrogen with the rare earth to form an interfacial insulating layer of either rare earth oxide or rare earth nitride. During the anneal the hydrogen layer is blistered and a portion of the second semiconductor substrate is removed and the surface polished to form a thin crystalline active layer on the interfacial insulating layer.

Abstract: Personal illicit drug detecting apparatus is disclosed which includes a substance chemically reactive to a suspected drug. The substance is provided in the form of a layer positioned on at least one finger of a user. The substance can be blended into finger nail polish and positioned on at least one nail by painting or positioned anywhere on a finger in the form of a decal. To test a suspected beverage the user inconspicuously moistens the substance on the finger or finger nail with liquid from a beverage and observes any change (e.g. color, image, etc.) of the layer on the finger nail or finger nail, wherein the change indicates the presence of the suspected drug in the beverage.

Abstract: A brassiere has two breast-receiving cups each having an inner breast-receiving surface and an opposing outer surface. A pocket component is affixed to the outer surface of one of the breast-receiving cups. The pocket component opposes a portion of the outer surface of the one of the breast-receiving cups. The pocket component and the portion of the outer surface of the one of the breast-receiving cups forms a storage space having a first shape and an opening into the storage space. A substrate, having a second shape, is disposed in the storage space and is capable of accepting writing applied thereto by a writing instrument, in which the substrate is removable from the storage space through the opening. The second shape of the substrate conforms substantially to the first shape of the storage space.

Abstract: A vehicle loader mechanism mountable on a vehicle having a cargo deck for lifting loads onto the cargo deck is disclosed. The vehicle loader mechanism includes a base mountable on the cargo deck of the vehicle and a lift mechanism movable between a lowered position and a raised position. A drive linkage is coupled between the base and the lift mechanism and movable between an extended configuration and a retracted configuration for lateral movement of the lift mechanism. A leveling linkage is coupled between the base and the lift mechanism for movement with the drive linkage and to prevent tilting of the lift mechanism during movement of the drive linkage between the extended configuration and the retracted configuration. A cylinder is coupled to the drive linkage for moving the drive linkage between the extended configuration and the retracted configuration.

Abstract: A sign assembly includes a fixture capable of being attached to a sign support structure. The sign assembly also includes a canopy which can slideably engage the fixture to provide cover for the sign support structure. The canopy can be foldable and can include lights to illuminate a sign held by the sign support structure. The lights can be provided power through contacts which are engaged when the canopy is attached to the fixture.

Abstract: An artificial nail apparatus includes an artificial nail with an upper surface, an opposing lower surface, and an end. The apparatus also includes a bridge having a first end fastened to the artificial nail at an engagement location and an opposing second end. A nail facing surface of the opposing lower surface is between the engagement location and the end. A digit receiving space is between the nail facing surface and the bridge and a digit engaging element is carried by the second end.

Abstract: A modular hand grip for use on a firearm, the modular hand grip includes an upper portion, a lower portion and a coupling assembly. A rearward end of the upper portion is configured to engage a top portion of a barrel nut. Lug rails having gaps therein project from an inner surface of the upper portion at opposing sides and proximate edges thereof. The coupling assembly is engagable with a bottom portion of the barrel nut and is attached to the rearward end of the upper portion. The lower portion has opposing side sections, each terminating at an edge. A plurality of spaced apart lugs extend from each edge and are receivable in the gaps in the lug rails of the upper portion and are translatable in one of a forward direction and a rearward direction positioning the lugs under the lug rails.

Abstract: A method of fabricating a semiconductor-on-insulator semiconductor wafer is described that includes providing first and second semiconductor substrates. A first insulating layer is formed on the first substrate with a first predetermined stress and a second insulating layer is formed on the second substrate with a second predetermined stress different than the first predetermined stress. The first insulating layer is bonded to the second insulating layer to form a composite insulating layer bonding the first substrate to the second substrate and a portion of the one substrate is removed to form a thin crystalline active layer on the composite insulating layer. The first and second insulating layers are formed with different stresses to provide a desired composite stress, which can be any stress from compressive to unstressed to tensile, depending upon the desired application.

Abstract: A rifle with an upper receiver and a barrel attached to the upper receiver and including a bolt carrier, and operating, buffer, and cooling systems. The operating system includes a cylinder and a piston coupled to receive propelling gases from the barrel. As the piston moves between retracted and extended positions the bolt carrier is moved between closed and open positions. The bolt carrier includes a weight movable within a guide frame between rearward and forward limits. The buffer system includes a compression spring in a tube attached to the upper receiver in abutting engagement with the bolt carrier. A partially fluid filled cylinder is attached to a coil of the spring and includes a piston and shaft. The piston is formed so that fluid in the cylinder restricts movement in one direction and allows free movement in a second direction.

Abstract: A highly efficient flame arrester adapted for use in preventing an external flame from backflashing upstream in a pipe, or a conduit, or a stream carrying a flammable substance. The flame arrester comprises a contained layer of nested ellipsoids formed from expanded metal sheets made from magnesium alloy foil. The arrester is useful in fuel tanks, combustion systems, sea-going tankers, hot water or space heaters, and the like.

Abstract: Finishing a seal assembly as a unit is proposed, which prevents alignment of the end gaps of the annular body and the annular ring of the seal assembly, provides the ability to manufacture the seal assembly to very low tolerances, and establishes virtually perfect parallelism between the upper and lower surfaces of the seal assembly. A finishing process is characterized by lapping a seal assembly as an assembled unit with a lapper using gritted oil as a polishing medium.
