Abstract: A higher efficiency roller screw system that includes a nut body designed to engage a threaded shaft. The nut body includes a center bore with closed, partial helical grooves formed therein. Disposed inside the center bore is a shaft with open helical threads formed thereon. A plurality of rollers with non-helical grooves formed thereon are also disposed inside the nut body's center bore and longitudinally aligned with the shaft. The grooves on each roller are designed to engage the grooves on the nut body and the threads on the shaft. The nut body includes a cross-over region where the trajectory of the internal grooves extend radially outward and axially. When the rollers' grooves contact the grooves in the cross-over region, the rollers are forced outward to maintain contact with the grooves on the nut body and are deflected axially. When they move outward, they disengage from the helical threads on the shaft.

Abstract: A motor vehicle window cage that fits into and extends through a motor vehicle opening that allows a pet to safely place it's head through the window opening when the motor vehicle is moving or parked. The cage is made up of a mesh-like material with a top mesh surface, two side mesh surfaces, and a front mesh surface. Formed on the cage is a rear opening and a bottom base. The bottom base acts as a shelf that allows the pet to stand in the seat and rests its front paws on the shelf. The cage is designed to confine the animal inside the motor vehicle yet allow the window to be extended downward to provide fresh air. The cage component can be easily attached and detached from the motor vehicle with two sets of adjustable straps that extend around the door's upper and lower frames without modifying or alternating the motor vehicle.

Abstract: A portable worklight designed to illuminate a 360 degree area. The worklight includes a triangular-shaped base with three side members. Mounted on each side member is a rotating and pivoting light head that includes two diagonally aligned light cavities. Mounted inside each light cavity is a horizontally aligned halogen bulb with a concave reflective shield mounted behind the bulb. Mounted over the front face of each light cavity is a glass plate and a chevron-shaped frame. Attached to the rear surface on each worklight includes a handle. Each light head is mounted on a rotating U-shaped bracket that allows the head to rotate upward and downward approximately 45 degrees. The bracket is also able to rotate 360 degrees over the side member. Each light head also includes a separately operated ON-OFF switch that controls the operation of the halogen bulbs contained therein.

Abstract: Flashing used on curved exterior wall projections designed to stop water intrusion and provide a permanent, attractive, paintable surface that is safe from UV radiation. The flashing includes a Z-shaped or L-shaped body bonded with a flexible flashing material along its front and back surface. The metal body includes at least two perpendicularly aligned flange members. Formed on the top flange member is a plurality of transversely aligned slits evenly spaced thereon that allow the flashing to be bent around a curved wall projection. The flexible flashing material is adhesively bonded to the inside and outside surfaces of the top flange member thereby covering the slits to create a water barrier. During installation, the top flange member and flexible flashing material are covered by external wallboards or siding.

Abstract: A laptop computer including a display securely attached by one or more swing arms, pivotally mounted at their opposite ends to the laptop body and the display, which allows the display to be manually elevated and rotated forward to a position over the keyboard of the computer. The swing arms are sufficient in length to allow the display to be positioned along the rear edge of the computer for normal viewing or rotated and elevated forward or upward for close-up viewing in tight viewing situations. The invention is ideal for near sighted individuals and for use in tight, restricted locations, such as an airplane seat, because the monitor can be moved upward and forward so the display screen is closer to the user and he or she can still adequately type.

Abstract: A chinrest pad system designed to hold a standard chinrest used with a string instrument that minimizes dampening of vibration and prevents damage caused by the metal components touching the edges of the instrument. The system includes pads located under the support surface of the chinrest member and on top of the lower lip plate used on the lower clamping member. The pads are specifically designed to partially engage the instrument's upper and lower edges and match the curvature of instrument surface immediately adjacent to the edge. Each pad also includes a rear extending lip that bends slightly around the upper or lower edge and extends rearward to prevent the metal rods used with the turnbuckles from contacting the rear surface. During assembly, the pads are positioned over the upper and lower edges so that the compression forces exerted by the support surface and the lower lip plate are centrally located over the sidewall transverse axis, thereby minimizing dampening of vibration.
