Abstract: A battery powered, automatic feed, disc type grater with a storage cover, interchangeable discs and waterproof motor gives users the ability for one touch operation and extended refrigerator storage and tap water cleaning of the components of the grater. A storage cap/container provides extended storage capability, while a ring stand enables the grater to be operated with the touch of a button while the grater is suspended over an area into which grated material may fall. A pusher assembly provides constant and automatic pressure on a material to be grated and against a grater disk, and a divider sleeve derives turning resistance for material to be grated from the pusher assembly while protecting the holder from contact with the material to be grated.

Abstract: A switching mode power supply uses two power source inputs, an alternating current input and a direct current input. A pulse width modulation controller is used to control current from two primary windings of a transformer. The secondary of the transformer has a rectified direct current output. From the direct current output a current/voltage comparator receives a signal across a sensing resistor and through an inverter and in parallel with respect to the direct current output. The current/voltage comparator may communicate through an opto coupler/isolator and then to a pulse width modulation controller. Instructions are received about the voltage and current necessary to be supplied by the direct current output of the power supply from an internal, circuit board mounted selecting network. The selecting network can be resistive, digital, fiber optical, black and white, or color.

Abstract: A light generating flashlight system device utilizes a large centrally located magnet which is mounted to slide past a magnet pickup or current induction wire which may be preferably mounted at a center point of travel in a tubular housing having a tubular chamber through which the magnet travels. A pair of elastomeric dampers are located each at the end of a support system sleeve which is sized to fit within a main housing to stabilize all internal support within a sealed unit. The result is a device which both facilitates the manual movement of the flashlight body so that the magnet slides past the center magnet pickup or current induction wire, and also conserves the residual momentum of the magnet once it has traveled past the magnet pickup or current induction wire by providing a bumper and spring to conserve some of the mechanical energy going in the other direction. Ninety second of manual activation enables about five minutes of illumination.
