NOVELTY - The supply has a kinetic electrical power generator (162) disposed within a housing (152). The generator generates electrical energy based on the housing motion that exceeds a predefined motion threshold. The generator processes the energy into an electric output power. A power output unit delivers the electrical output power from the generator to a functional component (154) during an electrical device (150) operation.    USE - Used for an electrical device, lighting system, chronograph, a miniature surveillance device such as remote mini-camera, concealable tracking device, motion detecting device, an electronic tag, personal electronic device such as mobile telephone, radio, television, personal digital assistant (PDA), media player and/or recorder, video or photo camera, game console, binocular, night vision goggle, a portable computer e.g. notebook, laptop, or tablet computer, portable data acquisition device e.g. RF or barcode scanner, portable medical diagnostic or treatment delivery device e.g. blood pressure monitor, electrocardiogram machine, implantable cardiac device e.g. pacemaker, and defibrillator, drug pump, weapon or weapon accessory e.g. rifle, taser, laser targeting sight, or laser targeter, toy, and robotic device, marine craft, space vehicle e.g. satellite, space shuttle, planetary robotic vehicle, extra-vehicular activity (EVA) suit, non-powered air vehicle.    ADVANTAGE - The generator has minimal motion thresholds and is of high efficiency. The generator provides lower operating temperature, and hence the generator can be used in military applications where low equipment temperatures provide an increased defense against temperature-sensitive enemy surveillance, reconnaissance and/or targeting. The generator provides energy to power electrical device, thus reducing a need for traditional lead acid batteries that are environmentally unsafe and expensive to dispose when used.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (A) an electrical device of a predetermined functionality requiring electrical power    (B) a method of providing electrical power to a device of predetermined functionality.
