Abstract: A correction and training tool to teach fundamentals of important actions and postures in baseball and softball games. To accomplish this, the device includes a shoulder strap, a wrist strap, and a detachable connecting link that connects the shoulder strap to the wrist strap. The connecting link may be made longer or shorter depending on the training goals. When worn on the glove arm of a user, the device restricts extension of the elbow of that arm while still giving room for slight motions, which makes it a great starter tool for young players who are just learning how to catch a baseball. The device helps improve fundamentals in pitching accuracy, catching, and fielding by not allowing the glove arm to fly open. Thus, the training device not only fundamentally helps reduce errors, but also improves accuracy in all fields.

Abstract: Disclosed is a door barricade for use as a home security device that serves to prevent a door from being opened by an intruder. A rigid, elongated bar extends horizontally across a doorway so as to physically prevent the door from opening. The elongated bar includes an L-shaped bracket on each end. Each bracket comprises a first section to be positioned flush against the wall on opposing sides of a doorway, and a second section to which an end of the elongated bar is secured. Bolts can be mounted on opposing sides of a doorway, and the first section of each bracket includes apertures thereon that are capable of receiving the bolts. Once a bolt is inserted through the aperture on the bracket, the shaft of the bolt can be positioned within a narrow channel on the aperture to removably secure the door barricade to the wall.

Abstract: Attachment hardware is provided to enable a folding bed cover for a pickup truck to be stored on the bed in a substantially vertical position giving access to substantially the entire bed. This hardware includes a latch to secure the lower end against sliding while any of 3 different devices are employed to lock the top of the vertically positioned cover in place. Several embodiments of devices are taught herein, including manual, mechanically-assisted and fully automated devices, for collapsing and lifting the cover into its substantially vertical storage position.

Abstract: A vibration unit is attached to one side of a plate having an adhesive coating on its other side. The adhesive coating is protected until the vibration unit is to be attached to an exercise device. The protection is then removed and the plate is attached to a mating surface on the exercise device.

Abstract: A collapsable spa enclosure includes a canopy that is carried by a frame that is supported by a plurality of support blocks. The support blocks are connected to the outer surface of the spa with an adhesive or a clamping strap. The collapsable spa enclosure may be removed from the spa by detaching the frame from the support blocks. The frame may be collapsed into a convenient storage size. When erected over the spa, the enclosure protects the spa user from insects, sun, and wind while providing the user privacy.

Abstract: The PMMA (Polymethyl methacrylate) plastic used to produce one-piece intraocular lenses is modified by a novel thermoplastic pressure forming process to produce a much tougher material with improved mechanical properties. The improved material exhibits greater ductility and fatigue resistance than conventional cast PMMA sheet, resulting in a one-piece lens that is less prone to breakage from implantation or use.
