Abstract: A manual gripping tool with an illuminated gripping end allows the user to find and manipulate small objects in close, dark environments. An illumination source on the gripping end of the tool illuminates objects in the close environment, allowing the user to see the desired object for manipulation. One preferred use is to recover lost objects that might have fallen or otherwise become lodged in the close environment.

Abstract: Water skiers towed behind a boat can be towed by varying lengths of rope automatically adjusted by letting out or reeling in the rope to provide different lengths. The rope, trailable aft of the boat having a first boat-connecting end and a second terminal handle end has at least one length indicator placed on the rope between the first boat connecting end and the second terminal handle end. The rope is connected to a winching means mounted on said boat attached to the first boat-connecting end. A switching means allows an occupant of the boat to actuate the winching means as the boat moves through the water. A sensing means senses the passage of the length indicator on the rope, and provides a signal to the winching means upon sensing the length indicator. This signal stops the winching means, disposing the sensing means within ten centimeters of the length indicator, thereby providing at least two precisely predetermined lengths of rope trailable aft of the boat.

Abstract: Acrylic and fiberglass fingernails are applied using an aid having a flexible fingernail support shield wrappable around the end of a human finger defining an aperture suitable to receive a fingernail. A substantially conical resilient pinching member defining an expandable slit is placed over the flexible support shield and the fingernail augmentation is applied over the shield.
