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. A ready charger is disclosed which uses induction to charge the flashlight system by proximity to the manual charging magnet wire.

23. A self contained, manually energizable flashlight comprising:
-
a magnet having a magnetic field;
a main housing;
a support system sleeve having a first end and a second end, for supporting a translating movement of said magnet toward said first end and toward said second end of said support system said support system for quick insertion into and dimensioned sealed carriage into said main housing;
a magnet wire positioned such that said magnet passes by said magnet wire each time said magnet makes said translating movement of said magnet toward said first end and toward said second end of said support system sleeve, energizing said magnet wire from passage of said magnetic field through said magnet wire upon said translating movement of said magnet;
a capacitor for storing an electrical charge;
a light emitting diode;
an AC power plug supported by said housing;
circuitry connected to said capacitor, said light emitting diode, said AC power plug and to said magnet wire for converting said energization of said magnet wire into an electrical charge stored in said capacitor when said AC power plug is not receiving an alternating current source of power, said circuitry for maintaining said electrical charge stored in said capacitor when said AC power plug is receiving an alternating current source of power, said circuitry also for providing said electrical charge stored in said capacitor to power said light emitting diode. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
