Abstract: A power generation device includes a body, an electric generator, a hub, and an arm. The body extends from a first end to a second end and a longitudinal axis extends from the first end to the second end. The electric generator is housed within the body and includes a rotor. The hub is coupled to the body at the first end and is rotatable with respect to the body about the longitudinal axis. The arm extends from the hub such that the arm is rotatable with the huh about the longitudinal axis. The arm is pivotably coupled to the hub such that arm is pivotable with respect to the hub about a pivot axis that is non-collinear with the longitudinal axis. Rotation of the hub and the arm about the longitudinal axis causes rotation of the rotor of the generator to generate electrical power.

Abstract: A programmable apparatus for laser beam shaping including a preprogrammable mircomirror array produces a spatial energy distribution suitable for accurately and rapidly marking, machining and processing materials. The preprogrammed micromirror array redistributes the laser output beam energy to produce a desired two-dimensional machining pattern on a work piece. The energy pattern created by the preprogrammed micromirror array is changeable between successive pulses of the laser to create accurate, complex three-dimensional machined shapes in a work piece not easily achieved by conventional machining systems. A special application of this invention is laser beam shaping to produce a uniform spatial energy distribution, i.e. homogenizing the beam from a laser with non-uniform energy distribution. Continuous adjustment of beam shaping is provided to maintain beam homogenization in accordance with changes in laser beam output energy profile.

Abstract: A laser machining device is capable of simultaneously machining two- or three dimentional patterns on the surface of a workpiece. A micromirror array positioned within a laser cavity generates a patterned plurality of laser beamlets which can be homogenized and deflected by a second micromirror array onto the surface of a workpiece to create a two-dimensional pattern. Alternatively, the second micromirror array can deflect laser beamlets of unequal energy density to produce a three-dimensional pattern.

Abstract: A method for making accurate and precise customized corrections to the surface of an optical lens is described. An electronic correction contour is generated from a measured refractive correction for a patient, and transferred to the surface of the lens by ablation etching with one or more laser pulses. After each of the laser pulses, the refractive properties of the lens are measured and compared to the electronic contour correction derived from a patient's refractive correction. The ablation etching is terminated in localized areas where the refractive properties match the electronic correction contour. End point detection includes monitoring refractive qualities of the lens during the recontouring process, modifying the pattern through changes in the laser pulses.
