Abstract: A solar charging umbrella uses solar power to charge electronic devices. The umbrella is self-sustained, capable of charging electronic devices in locations away from electrical outlets. The umbrella has a rechargeable battery that is recharged by sunlight. When charged, the umbrella's battery can charge devices when sunlight is not available. The umbrella supports simultaneous charging of high power devices such as tablet computers.

Abstract: A device for providing electrical power from light for charging a portable electronic device includes a frame structure, a shade attached to the frame structure, and a solar panel attached to the frame structure and positioned above the shade. The device includes a rechargeable battery configured to be recharged by the solar panel, and a charging terminal configured to connect to the portable electronic device and supply charge from the rechargeable battery to the portable electronic device.

Abstract: An LED light source assembly for signage illumination includes one or more planar LED arrays located with respect to a light spreading system for uniformly distributing light onto a viewing surface. The light spreading system includes a plurality of reflectors in combination with a transverse deflector disposed directly above and in the light emanating path of a planar LED array. The transverse deflector is oriented angularly and projects at least a portion of light onto a lateral reflector of the light spreading system. In one embodiment, a heat dissipation fixture is supported external to a housing assembly for improved heat management. The LED arrays and the plurality of reflectors and transverse deflectors are affixed directly to the heat dissipation fixture.

Abstract: A pulling device transmission includes an stepless V-belt connection two pulleys wherein at least one of the pulleys is an adjusting pulley which is composed by two halves between which the belt runs through. The operative diameter of the adjusting pulley is adjustable relative to the belt plane where the belt runs thereon and the adjusting pulley halves are symmetrically pre-stressed with respect to the belt plane. A variator unit is designed for displacing the travel path of the belt in the respective to the adjusting pulley.
