    摘要: An improved laser printer is provided that keeps its fuser at a standby temperature that is somewhat raised above the ambient temperature, which allows the printer to operate more quickly (to begin printing the first page) when a print job arrives at the printer. The time needed to raise the fuser's temperature is minimized, so that other printer operations become the determining factor in the time to first print parameter. The electrical energy that energizes the fuser is provided in a form that prevents light flicker, by use of AC waveform phase control, or by use of integer half cycle control. The present invention uses closed-loop feedback control, and the type of controller is a PID controller.

    摘要: The present invention relates generally to the provision of robust telecommunication to and from remote areas without reliably operating infrastructure such as electrical distribution power grid, telephone networks, and the like using a novel combination of equipment with a reduced data set and transmission protocols. The invention may be used in remote areas by lightly trained personnel or may be connected to remote unmanned sensors, and permits the collection of data from the field and the communication of signals back to the field.

    摘要: A lighting apparatus includes a first source of monochromatic light, a second source of white light, and a third source of polychromatic light. The light from the three sources combine to produce a resultant color of light from the apparatus. The intensities of the light emitted by the first, second and third sources are independently controlled by a controller to produce a desired resultant color of light. Varying the amount of electric current applied to each such light source by substantially an equal amounts to changes the luminance of the combined light with out affecting the resultant color. The lighting apparatus can be operated to replicate a Planckian radiator with a color rendering index of at least 80 throughout a substantial portion of the visible light spectrum produced by the lighting apparatus.

    摘要: A power converter for converting DC to AC power or DC to DC power includes an input circuit, a transformer, an output circuit, and a controller. The input circuit receives DC input power and creates high frequency pulses. The transformer transforms the high frequency pulses into at least two sets of transformed pulses, the sets of transformed pulses having alternating and opposite polarity. The transformer includes a primary winding and a secondary winding, where the primary winding is connected to the input circuit. The output circuit includes a plurality of switches for providing a full wave rectified or DC output, where the output circuit is connected to the secondary winding. The controller controls the switches to provide a continuous current path through the output circuit thus minimizing voltage spikes and ripple, and greatly reducing the cost and complexity of the output circuit usually required to handle these spikes and ripple. In addition, this provides for lagging currents typical of an inductive load and provides for clean zero crossing of the AC output wave.

    摘要: A feedback method on occasion independently senses a characteristic of light produced by each of several light sources in a lighting apparatus. The sensed value of that characteristic is compared to a reference value for the respective light source and that light source's operation is adjusted accordingly. This method has particular application in a lighting apparatus that produces different lighting effects by varying the intensity of different colors of light produced by the various light sources. The feedback method compensates for light emission variation as the sources age, thus ensuring that the lighting apparatus continues to produce the desired lighting effects. This enables multiple lighting apparatus in an area to be calibrated to the same standard so that uniform illumination is provided.
