  • Patent number: 4544043
    Abstract: An electronic scale used for weighing an object or material. The scale includes a weighing platform arranged to move upon receipt of a material thereon. The device further includes support means, a variable capacitor having a first and a second plate, spring means which is coupled both to the frame means and to the platform means such that movement of the platform means upon receipt of the material thereon causes the spring means to twist about an axis.
