Abstract: A magnetic flux switch having a substrate and an elongated rod having a first end attached to the substrate and a magnetic material attached to the second end. An electrostatic comb drive pivots the rod between a first and second pivotal position in dependence upon the input signal for the comb drive. In its first position the magnetic material is positioned closely adjacent a magnetic flux sensor on the substrate so that flux flow through the rod flows through the sensor which then generates an output signal. Conversely, with the rod in its second position, the magnetic material is spaced from the sensor so that flux does not flow through the magnetic flux sensor.

Abstract: A MEMS notch filter comprises a frame; a movable mass; resilient members connecting the mass to the frame; electrodes connected to the frame; and a comb drive connected to the frame and the mass which operates to drive the mass, wherein the filter is adapted to oscillate at least one resonant frequency. A mechanism is positioned below the mass, wherein the mechanism is adapted to maintain a neutral position of the mass and to expel fluid onto the mass. The comb drive is adapted to receive an applied voltage signal from the electrodes. This voltage signal is applied to the comb drive at a resonant frequency of the notch filter and induces the mass to oscillate in a geometric plane of the frame (or optionally in some other resonant mode); resulting in dissipation of energy and voltage attenuation. Other voltage components not at the notch frequency are not attenuated.
