A flashlight includes a circuit board received in a housing and having one or more light devices received in a front opening of the housing. One or more chargeable batteries are received in the housing and coupled to the light device for energizing the light device. An actuating device includes a follower rotatably attached to the housing, and a handle pivotally attached to the follower. A gearing device includes a gear coupled to actuate an electric generating device, to generate electric energy to energize the light device. A weight may be secured to the gear of the gearing device, to increase the moment of inertia of the gear, and to facilitate the rotational movement of the gear relative to the housing.

A method for compensating for attenuation in an input signal includes receiving an input signal, communicating a first portion of the input signal on a first path, communicating a second portion of the input signal on a second path, and communicating a third portion of the input signal on a third path. The method also includes applying a first gain to the first portion of the input signal, applying a first-order mathematical operation and a second gain to the second portion of the input signal, and applying a second-order mathematical operation and a third gain to the portion of the input signal. The method further includes recombining the first portion, the second portion, and the third portion into an output signal.

Various embodiments disclosed herein are directed to a portable lamp. Various embodiments of the portable lamp comprise a base having an upper surface, a substrate coupled to the base on the upper surface of the base, the substrate including at least one surface having a plurality of light emitting units disposed thereon, the substrate being movable relative to the base to direct light emitted from the light emitting units in a desired direction, and a light-transmitting cover surrounding the substrate.

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.

A renewable energy flashlight employing a pair of elastomagnetic repulsion members to assist in reciprocating a charging magnet passing through surrounding induction coils to enhance the efficiency of manually charging a capacitor to power an LED lens amplified flashlight.
