The embodiments disclose a pulsed power generator system that can include a cantilever comprising a cantilever tip disposed on a lower surface of a first end and a permanent magnet mounted on an upper surface of the first end, wherein the cantilever is connected to an electric circuit at a second end, an electromagnet generating a time varying periodic magnetic flux, wherein the magnetic flux interacts with the permanent magnet to generate a direction-changing mechanical force that drives oscillation in the cantilever, a conducting pad, disposed adjacent to the bottom surface of the first end of the cantilever and configured so that the cantilever tip can contact the conducting pad. An oscillation of the cantilever causes the cantilever tip to periodically contact the conducting pad forming an electrical switch suitable for pulse generation through the electric circuit.

A sensor for measuring a rotation speed of a magnetic encoder includes a first magnetic detector detecting a magnetic field induced from the magnetic encoder and outputting a strength value of the magnetic field as a first electrical signal, a second magnetic detector detecting the magnetic field induced from the magnetic encoder and outputting a strength value of the magnetic field as a second electrical signal, a first output signal generator for generating and outputting first rotation data including information indicating a rotation speed of a wheel based on the first electrical signal, and a second output signal generator configured to generate second rotation data including information indicating a rotation speed of the wheel based on the second electrical signal. The information indicating the rotation speed in the second rotation data may have a higher resolution than the information indicating the rotation speed in the first rotation data.

A pulse generator comprises a mounting to hold two bodies in proximity to each other. Two magnetic elements may be movably placed in the mounting, and the magnetic elements will align with each other in one of two stable states. A coil surrounds the magnetic elements in the mounting, and a force application device applies a force to the first magnetic element to cause the first magnetic element to break the current alignment and thereby make the first and second magnetic elements realign to the other stable state. The movement of the magnets generates a pulse in the coil which may be detected by suitable circuitry and used. The device may be used inter alia to count rotations or linear movements, or to provide switching or remote control without the need for a separate power source.
