Publication number: 20180256369Abstract: A programmable prosthetic foot includes a heel member simulating a heel portion of a human foot. The heel member has an elongated heel member shaft extending in a vertical direction. The foot also includes a forefoot member simulating a forefoot portion of a human foot. The forefoot member has an elongated forefoot member shaft extending in the vertical direction. A sensor on the foot detects compressive force on the heel member shaft and/or forefoot member shaft during a step. An actuator on the foot imparts vertical translation to the heel member shaft and/or forefoot member shaft. An electronic controller in operable communication with the actuator includes program instructions for operating the actuator by imparting the vertical translation to the heel member shaft and/or forefoot member shaft as a function of the compressive force detected by the sensor.Type: ApplicationFiled: May 14, 2018Publication date: September 13, 2018Inventors: Leslie D.

Patent number: 4098112Abstract: The first ends of two electrical probes extend through and are spatially separated on the interior of a steam turbine's crossover conduit expansion joint. The external, second ends of the electrical probes are connected to an electrical potential source in such manner as to cause the probes to be electrically opposite in charge. A current measuring device is electrically connected to the electrical probes and indicates electrical current flowing therethrough, which, in turn, provides a measure of the quantity of electrically conductive molten caustic which accumulates between the probes' first ends. The probes' first ends are placed in the expansion joint region where molten caustic is most likely to collect, allowing early detection of corrosive caustic during steam turbine operation. A non-corrosive baffle, disposed upstream from the probes' first ends, provides a shield for the first ends from steam born solid particles of low electrical conductivity.Type: GrantFiled: March 10, 1977Date of Patent: July 4, 1978Assignee: Westinghouse Electric Corp.Inventor: Leslie D.
