Abstract: Implementations of a power generator may include an enclosure including a cavity therein; a magnet supported within the cavity of the enclosure through one or more supports; and a coil disposed around the enclosure where the magnet may be configured to vibrate under the influence of one of a magnetic field generated by a coil or a resonant frequency emitted by a noise source where the vibration of the magnet generates electrical power with the coil.

Abstract: A resonant frequency power generator is disclosed. Specific implementations include a base, a magnet suspended within the base through one or more flexible connectors, and a coil disposed around the magnet. The magnet and one or more flexible connectors may be configured to vibrate at a resonant frequency emitted by a speaker, and the vibration of the magnet may generate electrical power with the coil.

Abstract: An electric generator. Implementations may have a pendulum extending downwardly from an axle. The pendulum may include a plurality of bar magnets oriented parallel to the axle and being arranged in an arc equidistant and coaxial from the axle. The plurality of bar magnets may be arranged in an alternating pole arrangement. The axle may be mounted between two base units with each base unit including a pickup coil positioned proximate to the arc. The pickup coils may generate an alternating electrical current as the bar magnets pass thereover.

Abstract: A locator device precisely identifies a predetermined spot which is hidden by a skin. The device is an outer washer and an inner washer with both washers being magnetized. The inner washer is positioned underneath the skin to mark the location of the predetermined spot therein. The outer washer aligns with the inner washer when proximate thereto to thereby locate said predetermined spot.

Abstract: A probe for sensing energizations of electrical components and particularly the energization of a relay or solenoid, the probe utilizing a magnetic switch as a sensor, a light-emitting diode as an indicator and a battery as a power source, the elements encapsulated as a unit in an epoxy material.
