Patent number: 6166335Abstract: A bathroom scale has a measurement value sensor which generates a measurement signal when a person wishing to be weighed stands on the scale. The measurement signal is transmitted to an evaluation circuit which reduces therefrom the weight and displays it on a display device. The evaluation circuit and the display device are supplied with electric energy by a generator upon which the weight of the person wishing to be weighed is applied. The actuation element for the generator is designed as a plunger which drives the generator by means of a toothed rack and pinion and projects over the plate in such a way that it can be actuated independently of the same. The restoring spring acts between the plate and the toothed rack and pinion.Type: GrantFiled: August 2, 1999Date of Patent: December 26, 2000Assignee: Soehnle AGInventor: Armin Soehnle

Patent number: 4614875Abstract: The present invention transforms the vast amount of existent vehicular travel into an equally-vast alternative energy resource employable for the generation of electricity. This transformation is achieved by means of a novel system which generally includes a momentum-conversion assembly configured to convert available vehicle momentum into operational momentum for an associated momentum-referenced electricity generator. The conversion assembly is accordingly structured to be responsive to the passage along an associated roadway of vehicles having predeterminable roadway-traversal momentum, with a portion of this momentum then being that which is cooperatively applied to the generator. The resulting double utilization of associated energy resources for both vehicle motion and electricity generation constitutes an effective increase in resource conversion efficiency.Type: GrantFiled: January 31, 1985Date of Patent: September 30, 1986Inventor: Terrill A. McGee

Patent number: 4291233Abstract: A wind-turbine generator system which transforms the rotational energy of a wind driven turbine blade into rotation in opposite directions of a rotor and a stator of a dynamoelectric machine to generate electrical power. A bevel gear rotating with the turbine blade drives two pinion gears and associated concentric shafts in opposite directions. The two shafts combine with a planetary gear set to provide the desired oppositely directed rotation. One of the shafts is associated with a ring carrier and drives a ring gear in one rotational direction. The other shaft drives a planet carrier in the opposite rotational direction. The planetary gear set is arranged such that a sun gear is driven in the direction opposite to that of the ring gear. A rotor is affixed to the sun gear by a spider support structure, and a stator, affixed to rotate with the ring gear, surrounds the rotor. The rotor and stator are thus rotated in opposite, mechanically and electrically additive, directions.Type: GrantFiled: January 29, 1980Date of Patent: September 22, 1981Assignee: Westinghouse Electric Corp.Inventor: Herbert S.
