Abstract: A sunshade for vehicles includes a plurality of segments each slidably secured to adjacent segments to form an elongated array which may be either extended to a full length, collapsed to a minimum storage length or partially extended to form an intermediate size array. Each segment is latched to its adjacent segment within the array to provide stable positioning. Each segment further supports a flexible subtle opaque shade segment which extends downwardly from its respective supporting segment. The entire array is positioned within a vehicle interior to provide an opaque shade covering the selected windows of the vehicle.

Abstract: A boat hull structure comprising a pair of laterally-spaced hulls having V-shaped bottom portions that are each symmetrical about a vertical plane extending through its longitudinal axis. A channel defined in each bottom portion that extends substantially along the length of each hull for trapping air and water to provide lift and to reduce "stuffing". Each channel defined by a pair of spaced, parallel and vertical channel walls and a horizontal base that interconnects the channel walls. A pair of strikes defined on each bottom portion that straddles the channel to define a high speed planing surface. The strikes preferably are located at the same elevation as the base of the channel so that the boat can plane on the strikes and the base of the channel at the same time. With this construction, the planing surface area of the boat hull structure is reduced, which enhances the speed performance of the boat hull structure.

Abstract: An elongated track receives and supports a movable wiper arm carriage having a windshield wiper extending therefrom. A plurality of pulleys couple the wiper arm carriage to an oscillatory drive mechanism having a reciprocating carriage. The pulley and cable system provides a distance multiplication in which the wiper arm carriage moves a substantially greater distance in response to motion of the oscillatory system carriage. A single direction drive motor is coupled to the oscillatory drive which includes a rotating arm together with a pivotally supported connecting arm and slider coupled to a guide bar supported upon and coupled to the oscillatory system carriage.
