Abstract: Three-dimensional solar power generation systems have a plurality of solar panels configured to include pole and equator facing panels and, in various embodiments additional top and/or side panels that form a segmented and dome-shaped assembly. The systems have improved efficiencies particularly with respect to early morning and evening power generation that enable improved power densities on a given land area as compared to traditional solar panel arrays. Methods of deploying the systems are also described.

Abstract: The present disclosure describes systems and methods to correct for perspective calibration variations of a variable thickness specimen with a single camera extensometer in a video extensometer system. In some examples, the systems and methods compensate for a change between a reference characteristic, such as a calibration plane, and an actual physical characteristic, such as a testing plane associated with a surface of a test specimen, during a testing operation. In some examples, a correction value is applied to an output (e.g., measured dimensions of the imaged test specimen) to compensate for the difference between the reference characteristic and the physical characteristic.

Abstract: Embodiments of the invention include a transistor comprising a gate region and an epitaxial region, the transistor comprising a frontside opposite a backside.

Abstract: The invention relates to a real-world simulation device suitable for being installed in a computer designed to support a multitask programming environment (23). The device comprises a simulation manager (30), capable of working in asynchronous chaotic mode by repetitive sequences (31) on distinct simulation elements (40-70). Each simulation element works with at least one space/time datum, termed the structure point. A space/time datum includes a property datum, defining a current state of the structure point, and designates a function, applicable for modifying this current state. Said simulation manager (30) comprises two coupled simulation sections, namely a first and a second section, that are designed to simulate respectively a fluid medium and a solid body in the presence of said fluid medium.

Abstract: An automatic traction control system is provided for an electric or hybrid-electric vehicle. The automatic traction control system may be used with vehicles using two separately excited motors where the armatures of the motors are connected in series to provide differential control. The automatic traction control system monitors and compares the voltages across the armatures of the two motors. If the voltage differential exceeds a predetermined threshold, it is determined that one of the wheels is spinning and current is diverted from the motor driving the spinning wheel to the motor driving the non-spinning wheel.

Abstract: Color photographic motion picture elements adapted to form a multicolor photographic dye image and an integral, infrared-absorbing, dye sound track and comprising 1-hydroxy-2-N-(5-alkyl-thiazol-2-yl)-naphthamide couplers that are capable of forming quinone imine dyes absorbing infrared radiation in the spectral range from about 600 to about 1000 nm by reaction with an oxidized aromatic primary amino developing agent, the thiazol-2-yl group of said naphthamide couplers bearing a 4-para-C.sub.1 -C.sub.4 alkoxyphenyl group or a 4-para-C.sub.1 -C.sub.4 alkylphenyl group, the hydrogen atoms of said C.sub.1 -C.sub.4 alkoxy or C.sub.1 -C.sub.4 alkyl being unsubstituted or at least one of them having been substituted by a halogen atom.

Abstract: A bucket using a box-like parallel-sided basket open at the front for dredging the sea bottom to collect nodules. The basket has a bottom wall with front and rear cross-bars and a plurality of parallel spaced rods extending longitudinally of the basket between the front and rear cross-bars. A front part of the bottom wall includes a grill formed by a transverse front link supporting one end of a plurality of longitudinal spaced flexible elements which are inclined downwardly towards the front and stretched between the front cross-bar and the transverse front link. Large shoes are positioned on lateral sides of the basket for supporting the bucket on the sea bottom. The grill is situated between the shoes with the transverse front link positioned in such manner that it penetrates the sea bottom. The basket is positioned inside the shoes and extends to the external edges of the shoes. The shoes include brackets for connecting a dredging line to the bucket.

Abstract: A guide is provided for the buckets of an endless dredging line comprising an emptying station incorporated into the guide. A system comprising a pair of trolleys and a pulley system is provided to hold each bucket stationary at the emptying station for dumping. The endless line travels over the pulleys, some of which are mounted on the trolleys. When a bucket approaches the emptying station, the trolleys are actuated to travel in opposite directions so as to allow the endless line to move at its normal speed while holding the bucket at the dumping station stationary.
