Abstract: A Quantum-dot Cellular Automata (QCA) device having normal QCA cells laid out in a planar structure such that there are a set of input lines, that may be columns, and a set of orthogonal, output lines, that may be rows. The device has clocking regions that control the flow of binary signals through the device. The input columns are driven by a separate input signal, and all the cells of each column align to match their input signal. These input columns then serve as drivers for output rows that act as serial shift registers under the control of clock signals applied to sub-sections of the rows. In this way, a copy of the contents of each of the input signals propagates along each of the output rows to an output cell. The output cells of each output row may be assigned their own, latching clock signal.

Abstract: We combine superplastic forming (SPF) with adhesive bonding (AB) to produce quality multisheet sandwich panel structures, especially those using a superplastic aluminum alloy, such as A1 2004, A1 8090, or A1 1570. We produce the parts with improved energy efficiency and at lower cost. We heat the multisheet pack having an adhesive, preferably a polyimide, between the core sheets and the face sheets to its superplastic forming range. Then, we superplastically form the pack to define adhesive bonds between the sheets in the core and between the core and the face sheets with the flowing adhesive. Finally, we cool the formed pack below the superplastic range to set the adhesive.

Abstract: A method of making an expanded metal sandwich structure includes cleaning at least two metal superplastic core sheets to remove metal oxides and residues that would interfere with diffusion bonding of the sheets. The core sheets are placed face-to-face and a gas pressure line fitting is inserted between one edge and is welded into place. The fitting has a through bore through which gas can flow under pressure from a gas pressure control system into the space between the core sheets. The core sheets are pressed together and laser welded together into a core pack along lines which will form junction lines between the core sheets when the core pack is superplastically expanded. The core pack is chemically cleaned to remove metal oxides and residues that would interfere with diffusion bonding of the core pack sheets to face sheets. Two metal face sheets having superplastic characteristics are chemically cleaned and placed over and under the core pack.

Abstract: An automatically guided agricultural vehicle with multiple sensors is disclosed. The automatically guided agricultural vehicle includes guidance parameter identification using multi-sensor data fusion for real-time vehicle guidance. To insure robust navigation, a map-based guidance and sensor-based guidance are disclosed and integrated because no individual sensing technology is ideally suited for vehicle automation under all modes of use. The appropriate sensor and operational mode will depend on the field status of time or operation. A fiber optic gyroscope (FOG) and a real-time kinematic GPS (RTK-GPS) and machine vision are added to the guidance system in order to improve reliability of the system for vehicle guidance. The navigator includes key functions of selecting control mode, correcting position by vehicle roll/pitch inclinations, Kalman filtering, and calculating a steering angle.

Abstract: A superplastically formed, diffusion bonded sandwich structure having integral metal hardpoints, made by joining two superplastic metal core sheets together into a core pack by welding or diffusion bonding along a pattern of lines which form junction lines between the core sheets when the pack is inflated by gas pressure at superplastic temperatures. Face sheets are laid under and over the core pack and metal inserts are interposed between the face sheets and the core. All of the sheets in the pack are sealed together around an outside peripheral edge to create a gas tight envelope. The pack is heated to superplastic temperatures in a cavity in a die, and the top and bottom face sheets are diffusion bonded to top and bottom surfaces of the metal insert by application of heat and pressure from top and bottom inner surfaces of the die cavity.

Abstract: A method of making an monolithic metallic sandwich structure includes selecting at least two chemically clean metal core sheets having superplastic characteristics and placing them face-to-face. The core sheets are welded together into a core pack along intersecting lines that will form junction lines of webs defining cells between the core sheets when the core pack is expanded superplastically. Gaps are left adjacent to the intersections of the weld lines to produce openings through which gas can pass to pressurize each cell. The position of the gaps adjacent the weld line intersections minimizes strain on the marginal regions around the openings as the core pack is inflated, to reduce the tendency of the sheets to tear or rupture around the openings. A gas pressure line fitting is inserted between one edge and the core pack is welded around its periphery with the gas fitting protruding from the edge for connection to a gas source that will purge and pressurize the core pack with gas.
