    Abstract: A lift device for use in raising and lowering personal watercraft, often known as jet-skis, and small boats having a weight of up to about 2000 pounds. The lift device, which is portable and weighs less than about five pounds, has a pair of engaging members, shaped so as to securely engage the gunnels or upper edge of each side of a personal watercraft or small boat. Lifting members are connected to each end of the shaped engaging members forming a pair and are connected on the other end in an inverted V-shape to an attaching mechanism. The attaching mechanism allows the lift device to be removably attached to a raising or lowering device such as a winch. In its method of use, the attaching mechanism is attached to a raising or lowering device, the shaped engaging members are placed securely around the gunnels of each side of the personal watercraft or small boat, the raising or lowering device is activated, and the personal watercraft or small boat is raised out of or lowered into the water.

  • Patent number: 5661468
    Abstract: A system for remote control of electrical load devices, particularly electrical lighting where the commands are broadcast over a radio pager system. A radio pager receiver is located within or nearby the electrical light fixture and is normally in a standby state, receives the commands broadcast. The radio pager receiver is connected to a computer processor and electronic circuitry. The computer processor interprets the commands and instructs the electronic circuitry to perform a desired operation. These operations include but are not limited to turning an electrical light element or group of electrical light elements on or off, dimming the light element or reprogramming the electrical light element to be included in a different control group of lights. Before the operation is accomplished, the computer processor checks for the appropriate security code entry.
