Abstract: The present invention includes a modular and removable watercraft platform for providing storage, stability, and mounting means to a user of a PWC. The modular watercraft platform of the present invention is directly for use in fresh and salt water and use with multiples sizes, brands, and types of PWC through multiple adjustment members. The modular watercraft platform allows the user to convert a stock factory PWC to include a front support assembly and a rear platform assembly. The modular watercraft platform allowing for storage, transport, and mounting of various items and accessories, as well as facilitating recreational activities upon the front support assembly and/or the rear assembly.

Abstract: A hazard perception test system comprising a CRT screen for displaying a sequence of images of a scene to be viewed by a test subject and in which at least one hazard appears, the images establishing a state of relative movement between the at least one hazard and the test subject, a computer for generating a select signal in response to an action by the subject, the select signal representing an image in the sequence selected by the subject as a point in the sequence at which to change the state, and for determining the ability of the subject to satisfactorily perceive hazards on the basis of the select signal.

Abstract: The opener comprises a base which is attached to support structure and provides a member extending generally horizontal and a lift tab engagement element hinged to the end of the generally horizontal base member. The engagement fits over the rim of the top of a lift tab container and under the tab, extending somewhat past the effective hinge point of the tab on the container top and positioned laterally with respect to the lift tab by a flange on each side of the element. A tab extends from each flange part way over the top of the lift tab. The engagement element is hinged so that it can deflect downward only from its essentially horizontal at rest position and is returned to that position by a spring. In use the container is maneuvered to engage the lift tab in the engagement element and then moved so that the engagement element pivots on its hinge axis, functions as a Class 2 lever and opens the container. Reversing the opening motion puts the lift tab into close to its original position.

Abstract: The subject device comprises two cams structurally supported from a base attachable to a vertical surface. The cams are positioned to interact with the lift-tabs of lift-tab containers as the container is in a vertical position and moved first toward the device and then from it. As the container is moved toward the opener, one cam engages the lift-tab and lifts it to open the container. As the container is moved away from the opener, the other cam depresses the lift tab to approximately its position before the can was opened. The cams are positioned one behind the other in a line perpendicular to the vertical surface. The tab lifting cam extends below the tab depressing cam and is the closer of the two to the base. The end of the lift tab moves below the end of the depressing cam as the container is moved into the opener and raised by the lifting cam. The lifted tab is then engaged and depressed by the depressing cam as the container is moved away from the opener.

Abstract: A formed, or molded, wall mounted bracket which extends horizontally from a mounting surface and serves to "one-handedly" raise a lift-tab on beverage cans and others, so equipped, by placing the upper surface of the above mentioned cans beneath a downward projecting nose at the individual's end of said bracket and pushing the container in one smooth motion toward the bracket, thus causing the downward facing projection to wedge the lift-tab upward and through an arc of nearly 100.degree. and, further causing the lift-tab to break the container's seal which, in turn allows the individual access to the contents within.
