Abstract: A method, system, and computer program product are provided for controlling the blending of pixels using alpha values. The alpha value of a first pixel is compared to the alpha value of a second pixel. The results of the comparison are then used to choose a particular blending operation from among two or more possible blending operations that are made available. The chosen blending operation is then performed so as to produce a blended pixel. The output of the blending operation is referred to hereinafter as pixel display data and includes a set of color coordinates and an alpha value for the blended pixel. The pixel display data is then sent to a frame buffer.

Abstract: A system and method for reducing pulse-to-pulse energy and peak power variation in various types of pulsed lasers, and in Q-switched lasers in particular. The system of invention has a laser cavity with a lasing medium pumped by a pumping device for delivering to the medium a pumping energy E.sub.pump. The system further includes a detection device and circuitry for determining the pulse magnitudes M.sub.i of laser pulses i, such as peak pulse amplitudes A.sub.i, pulse energies E.sub.i, pulse widths W.sub.i or other pulse metrics. According to the method of invention, a feedback mechanism which is in communication with the pumping device ensures pulse-to-pulse stability by increasing the pumping energy E.sub.pump when pulse magnitude M.sub.i of laser pulse i exceeds a mean pulse magnitude [M] and decreasing the pumping energy E.sub.pump when M.sub.i is less than [M]. Alternatively, the feedback mechanism is in communication with the switching device which controls that variable loss factor of the Q-switch.

Abstract: A novelty device to simulate use of a remote control unit is provided with a housing having side walls, a first end wall spaced from a second end wall, and a top wall. A plurality of end wall slots arranged in a parallel relationship are directed through the second end wall, with the top wall having a like number of top wall slots, where each top wall slot includes as associated projection in mechanical relation to a drive link and projection plate, wherein each projection plate is arranged for projection through one of the second end wall slots upon directing an associated link guidingly along an associated top wall slot.

Abstract: A compact fluorescent lamp employs an inner exhaust tubulation formed from glass which is opaque to a given range of electromagnetic radiation. The exhaust tubulation is non-invasively sealed after an outer lamp envelope is sealed by directing upon the exhaust tubulation an amount of such radiation sufficient to heat the tubulation to its softening point. The outer envelope is transparent to the given radiation which, in a preferred embodiment, is in the range of 400 nm to 2500 nm.
