The device has an elongate housing, a power-requiring functional element, a hinge element at the back of the housing, and a crank arm having an end rotatably attached to the hinge. The hinge allows the crank arm to rotate within an arc of 270 degrees between a resting position and an operating position. The arc is within a plane that includes the longitudinal axis of the housing. In the resting position, the crank arm is parallel to the housing; in the operating position, it is orthogonal thereto. The hinge is rotatable about the longitudinal axis of the housing, and consequently so too is crank arm. The hinge is connectable to a generator; rotation of the hinge element powers the generator, and the generator provides power to the power-requiring functional element such as a light-emitting element.

  • Patent number: 8573798
    Abstract: Embodiments herein provide a switch module for a flashlight with a single input contact and multiple output contacts. The switch module may include multiple mechanical actuators, each actuator configured to selectively and communicatively couple one of the output contacts to the input contact. Each actuator may be activated and/or deactivated independently. Accordingly, any combination of the output contacts may be activated and/or deactivated at a given time. The switch module may be incorporated into a flashlight, allowing any of a number of output devices (e.g., light bulbs) to be independently switched on and off from a common power source.

  • Patent number: 8556449
    Abstract: A combined flashlight and lantern which provides multiple configurations combining features of a flashlight and a lantern, further comprising a flashlight housing similar to a conventional flashlight. The apparatus further includes a lantern assembly extendible from a lower end of the housing such that the apparatus can be placed on a horizontal surface and the lantern end withdrawn from the housing to provide a lantern function. The lantern assembly further includes a multi-position switch for cycling through various lighting functions. When the lantern assembly is retracted, a flashlight switch allows the apparatus to function as a high-power spot beam flashlight. A user can actuate both the flashlight switch and lantern switch to operate both functions simultaneously.

  • Patent number: 8529088
    Abstract: Disclosed is a method and apparatus for providing a light emitting diode and driving circuitry integrated into a component module that will retrofit common incandescent lightbulb applications. The disclosed embodiments will perform with high efficiency at a wide operating voltage range with a very small size allowing for the incorporation within the envelope and form of existing lightbulb bases. Therefore, a single universal LED light bulb module can be used to replace the dozens of conventional LED and incandescent lights currently being used. The electronic circuitries used to drive the LEDs are extremely compact and consequently can be incorporated in nearly any standard bulb base.

  • Patent number: 8444290
    Abstract: A flashlight has a casing extending along an axis and adapted to hold an electric power supply, a light source fixed at a front end of the casing and electrically energizable to emit an axially forwardly directed light beam, an annular head fitted to the casing and axially shiftable thereon. Stops engaged between the head and the casing limit axial travel of the head relative to the casing. A lens is fixed in the head so that the lens and head can be shifted to focus the light beam. Thus the lamp head is captively attached to the casing. This creates an extremely compact structure that can be assembled quickly, thereby allowing manufacturing costs to be reduced. In addition, damaged components can be replaced quickly and easily.

  • Patent number: 8439516
    Abstract: A device with at least two light sources operating in context with each other under electronic control of illumination angle and intensity in order to create a wide angle stereoscopic view of the area. The device uses multiple switched sources of light situated at an angle in reference to a light source positioned along the longitudinal axis of system. The device works by sequentially switching each individual light source on and off in selected patterns at a frequency equal to or higher than 30 Hz. The device covers a selectable illumination area at variable view angles from the focused forward beam from over 3 steradians in the Left, Right, Up or Down direction, or to more than 6 steradians in full-view mode, when an axially aligned center source is present. The device finds applications, in automotive, aircraft, watercraft, space vehicles, flashlights and other fields of human activities.
