Abstract: A video signal processing apparatus comprising an edge detecting means for detecting an edge portion of an image to color difference signals; a region dividing means for dividing, except the detected edge portion, the image into regions determined in accordance with the levels of luminance signal; and an intra-region averaging means for averaging the color difference signals in the individual divided regions. The color difference signals in the edge portion are outputted directly, while the color difference signals in the divided regions are outputted after being averaged. Except the edge portion where variations of the color difference signals are conspicuous, the image is divided into one or more regions determined in accordance with the luminance signal levels, and the color difference signals in the individual regions are averaged. Since the color difference signals are averaged in the portion where color variations are little, any video signal noise that causes color nonuniformity and so forth can be eliminated in such portion having little color variations.

Abstract: A switch mechanism opens a contact set (1,2) in the event of an undervoltage condition. The mechanism involves a lever assembly (3) biased by a spring (9) for pivoting about one or other of two fulcrums to open or close the contacts respectively. The undervoltage causes a solenoid (6) to release a plunger (7) which initiates operation about a fixed fulcrum (8). A reset device (10) is used manually to initiate operation about a movable fulcrum (4) provided that the voltage is sufficient. An arm (5) is deflected by the plunger to shift the movable fulcrum and also acts to restore the plunger during reset. The switch mechanism may be incorporated in a residual current device which provides the undervoltage condition on detecting an electrical fault.

Abstract: An image editor stores color pixels for an image to be edited in an image pixel buffer (61) and a lookup register bank (47). The stored image is displayed on a monitor (35). An operator uses a mouse (52) to designate a screen path that identifies an object in the image, and pixel position data is detected for the screen path. A programmed computer determines in real time one or more criteria for a search controller on the basis of hue, saturation and luminance variables which are determined from the stored pixel color data for pixels along the screen path. The computer further searches the image pixels to identify the object and its boundaries in accordance with the search controller criteria, and applies color edit actions to the identified object within the image.

Abstract: The invention provides a process for preparing a suspension of cyanuric chloride in an aqueous liquid (fluid), in particular water. Cyanuric chloride melt is sprayed using a spray device having a spray nozzle immersed in the aqueous liquid. Blockages in the nozzle during the critical running-up (starting) and running-down phases are avoided by passing, before and after spraying, superheated steam through the parts of the spray device coming into contact with cyanuric chloride melt. A particularly reactive cyanuric chloride suspension is obtained by spraying a mixture of cyanuric chloride melt and superheated steam. <IMAGE>

Abstract: An optical system is disclosed which utilizes a pair of binary diffraction optic lenses (40,42) to reprofile the intensity of an input light beam (30) across its width. Both binary diffraction optic lenses have a plurality of segments (40a-40j,42a-42j). Depending on the shape of a desired intensity profile (50) of the output beam, at least some of the segments of the first binary diffraction optic lens either diverge (40e) or converge (40a) a portion of a light beam and as needed deflect the same portion of the beam. The second binary diffraction optic lens (42), which is located downstream of the first binary diffraction optic lens, has an equal number of segments as the first binary diffraction optic lens. Each segment of the second binary diffraction optic lens receives the light beam from a respective segment of the first binary diffraction optic lens and collimates the light beam.

Inventor: CYGAN LAWRENCE FRANCIS
IPC: H03F1/52
Filed: 1994-04-29
Abstract: Power amplifiers, which include a feedback element, may be protected from excessive operating power levels by adjusting the feedback element to reduce the drive signals to the power elements. This is accomplished by sensing the output power of the power amplifier to produce a sensing signal (300, 301). When the sensing signal exceeds a predetermined threshold (302), a feedback element is adjusted (304) to produce an increased feedback signal. The increased feedback signal is subtracted from an input signal (306), thus decreasing the drive signal. With the drive signal reduced, the output power is reduced proportional to the adjustment of the feedback element.
