| Number | Title | Issue Date |
| 7183880 | Discrete inductor bank and LC filter A discrete inductive-capacitive (LC) filter selects between at least two inductor banks to tune the LC filter. The filter receives an input signal that includes one or more bands of frequencies. A control signal selects a band of frequencies for processing. A first ... | 02/27/2007 |
| 7126495 | Linear electric encoder with facing transmitter and receiver A capacitive motion encoder, for sensing the position of a moving object relative to a stationary object, includes at least one stationary element, coupled to the stationary object and a moving element, coupled to the moving object and in proximity to the stationary... | 10/24/2006 |
| 6955097 | Radial movement capacitive torque sensor A radial movement capacitive torque sensor includes a pair of concentric capacitor plate rings lying in a common plane, a capacitor plate ring facing the pair of concentric capacitor plate rings, and a paddle assembly disposed between the pair of concentric capacito... | 10/18/2005 |
| 5099386 | Variable-capacitance position transducing A variable-capacitance transducer detects the angular position of a rotatable member. The transducer includes a first capacitance plate having a plurality of electrically conductive capacitance electrodes, a second capacitance plate spaced therefrom, and ... | 03/24/1992 |
| 4649761 | Rotary shaft holding mechanism for a rotary variable element A rotary shaft holding mechanism for a rotary variable element comprises a frame for rotatably supporting a rotary shaft of a rotary variable element such as a variable capacitor, a resilient member fixedly mounted to the frame for urging the rotary shaft... | 03/17/1987 |
