Abstract: A sensor device (15) for a prosthesis, in particular for a leg prosthesis, is provided for measuring forces acting on the prosthesis, having a ring-shaped outer member (16) of closed construction and an inner member (21, 22) connecting two opposite inner sides (17a, 17b) of the outer member having a sensor element (31) for measuring the force acting in the direction of the connecting axis. The outer member deforms under the action of a bending moment while the inner member (21) feels only the axial force acting in the direction of its connecting axis. By this means measurement of the axial force unaffected by bending moments is possible. Furthermore, the sensor device is able to transmit loads.

Abstract: A thick film resistor strain gauge is applied to a stainless steel shell portion of a spark plug. There are two preferable ways of applying a thick film resistor to the metal shell. In a first embodiment, the thick film resistor may be directly printed on to the shell portion with special screen printing equipment.

Abstract: A high-speed steel flywheel for a flywheel uninterruptible power is constructed by stacking several unpierced steel discs together. Each disc is heat treated prior to assembly. Thin axial thickness of each disc enables complete rapid quenching to attain a fully hardened condition and development of high tensile strength. The individual discs are machined or ground to shape and assembled to form an axially thicker flywheel capable of storing several kilowatts of energy or more. The discs are attached together by welding, brazing, soldiering, bonding or an interference assembly. The stacked disc configuration minimizes chances of catastrophic failure of the flywheel due to initiation of a crack in a single disc by restricting axial crack propagation to that single disc, and supporting the cracked disc by one or more adjacent discs until the flywheel can be safely decelerated.

Abstract: The present invention is a rechargeable electric corkscrew having a reversible rotatable auger mechanically associated with a motor contained within a hand held housing unit.
