摘要： A machine includes a component. The machine may also include a position-sensing system with a plurality of sensor elements that each generate a signal related to proximity of the sensor element to the component by generating the signal based at least in part on the magnetic permeability of the space adjacent the sensor element and a time-varying magnetic field generated by an electric circuit of the position-sensing system. The machine may also include one or more information-processing devices that determine a positional relationship between the component and the plurality of sensor elements based on a plurality of the signals generated by the sensor elements.

摘要： A speed sensing device for use with a traction device is disclosed. The speed sensing device has a rotor having a first rotational, wherein the rotor has magnets affixed thereon to generate a magnetic field. The speed sensing device also has a power-harvesting circuit coupled with the rotor to convert fluctuations in the magnetic field into electrical energy. The speed sensing device further has a sensor having a second rotational speed different from the first rotational speed, wherein the sensor is powered by the power-harvesting circuit to generate a signal indicative of a speed of the traction device. The speed sensing device still further has a transmitting circuit connected with the speed sensor and powered by the power-harvesting circuit to wirelessly transmit the generated signal.
