    摘要: An algorithm locates valid light spots produced on an image detector by a wavefront of interest. The algorithm includes sequentially examining pixels of the image detector to determine for each of the pixels whether the light intensity detected by the pixel is greater than a threshold, When the pixel's detected light intensity is determined to be greater than the threshold, the algorithm includes: determining whether the pixel belongs to a valid light spot; and when the pixel is determined to belong to a valid light spot; saving data indicating a location for the valid light spot; and masking out a group of pixels of the image detector at the determined location such that the masked pixels are considered to have a light intensity less than the threshold for a remainder of the sequential examination.

    摘要: A discrete low-noise amplifier designed to operate in a mobile wireless environment uses two cascaded GaAs FETs to achieve 25 dB gain and 0.9 dB noise figure at 2.5 GHz. Active bias control circuitry responsive to monitored amplifier output power automatically and continuously adjusts the drain-source currents, and the load lines, of the cascaded FETs to (i) maintain power consumption at 33 milliwatts in nominal small-signal conditions, and to (ii) provide an elevated input third-order intermodulation intercept point (IP3) and a reduced noise figure during the presence of jamming. A 15 dB improvement in the input IP3 is achieved in large-signal operation. Amplifier operation is supported by an a.c. power detector of enhanced sensitivity and responsiveness because of un-grounded operation.

    摘要: An electronic ballast has control circuitry to operate a gas discharge lamp in both full and dimmed illumination modes. A dimming controller serves as the mechanism to permit a selection between full and dimmed illumination modes. The dimming controller signal has a dimming request range which describes the range of dimming controller signal magnitudes. The electronic ballast also includes a full power circuit having a power control coupled to the dimming controller output to receive the dimming controller signal. The full power circuit also has a full power output that can couple to the lamp. When the full power circuit receives the dimming controller signal, via the power control, and the dimming controller signal is not in the dimming request range (i.e. the full illumination mode has been selected), the full power circuit generates a full power signal capable of driving/operating the lamp(s) in the full illumination mode. A filament heating circuit has a heating input coupled to the reduced power circuit, to receive the reduced power signal, and a heating output that can couple to the filaments of one or more lamps. When the reduced power signal is present, the filament heating circuit generates and provides a filament heating signal to the filaments, via the heating output. The filament heating signal maintains the temperature of the filaments when the lamp(s) are operated in the dimmed illumination mode. Further, the filament heating signal is responsive to the reduced power signal.

    摘要: A method of conducting sales over the computer internet where the prices of the merchandises are dynamic functions of time instead of static rational numbers. In one embodiment, this method and system is a free market place that's able to conduct single-unit or multiple-unit sales of products and services from multiple sellers. In this market place, negotiation of the price does not require either side to make arbitrary offers, and further, with a large pool of prospect buyers, the true, current market value of the on sale products and services can be automatically reflected and updated through the purchases made.
