Abstract: A photovoltaic module comprises an elongated base member having first and second extensions shaped to define an elongated support plane along ends thereof, the elongated support plane extending in a direction of elongation for the elongated base member. The photovoltaic module also includes at least one photovoltaic cell assembly positioned at the ends of the elongated base member, extending generally along the elongated support plane. The elongated base member and the at least one photovoltaic cell assembly define a volume of space therein.

Abstract: In an industrial equipment network, each piece of equipment is provided a dedicated controller for providing control and identification information, and for being programmed to provide the interconnection and interaction of its associated piece of equipment with other equipment connected to the network, thereby permitting a SCADA system, via broadcasting from the controllers or polling the controllers, to self-configure itself to show a diagram of the entire equipment network and periodically update the diagram relative to changes thereto, and the status of the equipment on the network.

Abstract: A wallboard patching element is collapsible to fit through a hole in the wallboard. Using a handle, the element is moved through the hole and inside the wall adjacent to the hole. Once inside the wall, the element is released into a fully deployed condition with part of the element larger than the hole. The patching element has adhesive on portions that contact the wall, and is moved into contact with the wall. Once the patching element is fixed to the wall, the handle is removed, and tape or other patching material is used to fill in any gaps remaining between the patching element and the wall.

Abstract: Circuitry that controls a multiple-plate charged particle beam deflection arrangement includes a Digital Signal Processor (DSP) acting through a separate accumulating Arithmetic Logic Unit (ALU) connected to each of the plates. For each line to be scanned, at the commencement of the scanning of the line, the DSP delivers to each accumulating ALU a separate signal composed of a digital number representing an initial value (if any) and a digital number representing a step size. During each subsequent cycle of a clock, each accumulating ALU successively adds the step size to a resulting cumulative sum. This cumulative sum depends upon the initial value (if any) plus the step size multiplied by the number of cycles that have elapsed since the initial cycle.

Abstract: Electronic devices such as hybrid integrated circuits such as those having test points spaced less than 1250 .mu.m are advantageously evaluated utilizing a two-probe process. In this process the probes are moved between test points in a pattern that reduces movement distance without concern for any ordering imposed by the nets themselves or the test to be made. Additionally, the test is made so that the movement time is the limiting factor.
