Abstract: Components, systems and methods for generating variable frequency AC voltage from a DC power supply are described. The components include a full-bridge (FB) parallel load resonant (PLR) converter which operates in discontinuous conduction mode. The PLR converter includes MOSFETs in an H-bridge configuration and employs a topology which minimizes inductance. The PLR converter can be coupled to a single or poly-phase bridge for use as an inverter. The inverter can be used to produce an AC sinusoidal waveform from a low voltage, high current DC power supply. Systems and techniques for modulating the output from the PLR converter to produce an AC sinusoidal waveform having desired characteristics, including frequency and voltage, are also provided. The PLR converter can also be coupled to a rectifier for use as a DC-DC converter.
Abstract: This invention relates to a method of an assay of genomic nucleic acid. Additionally, this invention relates to various methods to detect or screen for designated genetic sequences or portion thereof derived from a biological sample. More particularly, this invention relates to the use of magnetically responsive magnetic particles that function to reversibly bind genomic nucleic acid. A portion of the purified genomic nucleic acid is detected in solution by a variety of methods.

Abstract: Unique brackets, which form a bracket assembly that may be placed at any location of various components to form an assembly piece, such as furniture are disclosed. An assembled furniture piece made of furniture panels interconnected with attached engaging and receiving brackets is provided. The engaging and receiving brackets are positioned on components to facilitate the connection of the components. A method to assemble furniture having preformed arm, base, seat and back components is provided. This method of assembly saves on shipment costs, and facilitates the repair of damaged furniture.
Abstract: A silicon carbide semi-insulating epitaxy layer is used to create power devices and integrated circuits having significant performance advantages over conventional devices. A silicon carbide semi-insulating layer is formed on a substrate, such as a conducting substrate, and one or more semiconducting devices are formed on the silicon carbide semi-insulating layer. The silicon carbide semi-insulating layer, which includes, for example, 4H or 6H silicon carbide, is formed using a compensating material, the compensating material being selected depending on preferred characteristics for the semi-insulating layer. The compensating material includes, for example, boron, vanadium, chromium, or germanium. Use of a silicon carbide semi-insulating layer provides insulating advantages and improved thermal performance for high power and high frequency semiconductor applications.

Abstract: Described is a low-emission adhesive, whose polymers are dissolved in a mixture of acetone and ethanol. The adhesive is characterized by very low emissions of solvents, with otherwise equally good properties compared to standard solvent-synthetic resin based adhesives. In particular with respect to viscosity and spreadability, surface tension, depth of penetration, wettability, simplicity and speed of processing, as well as adhesion, gluing strength and adhesive spectrum, the adhesive of the invention is equal to other adhesives based on solvents and thus superior to dispersion-adhesives that are based on aqueous solutions. Due to its low solvent emissions and absence of chlorinated solvents, the present adhesive is suitable for applications for which only dispersion-adhesives that are based on aqueous dispersions were reserved until now. This is true in particular for applications in enclosed spaces. The adhesive is very suitable for gluing of wooden floors in internal construction work.
Abstract: The present invention provides a method and apparatus for to conduct transgenic and targeted mutagenesis screening of genomic DNA. This invention also provides a system for screening DNA for a designated genetic sequence. The system includes a computer having a processor, memory and web browser, wherein the computer receives instructions concerning the designated genetic sequence and other screening parameter selected from a remote user via a form of electronic communication, and an automatic screening device that analyzes samples of genomic DNA for the designated sequence.
Abstract: A method and system for detecting the presence of subterranean termites, involving use of a thermal imaging camera to scan the structure before installation of an acoustic sensor in order to quickly locate potential areas of subterranean termite infestation, and an acoustic sensor in the form of an accelerometer or the disclosed innovative acoustic sensors having a bandwidth of at least 100 Hz to 15 kHz to detect noises made by the subterranean termites. Information collected by the acoustic sensor may be transmitted to a portable mini-computer (pocket PC) for confirmation and to a central operations center for inclusion in a comprehensive database of termite data and information.

Abstract: Remotely sensed spectral image data are used to develop a Vegetation Index file which represents spatial variations of actual crop vigor throughout a field that is under cultivation. The latter information is processed to place it in a format that can be used by farm personnel to correlate and calibrate it with actually observed crop conditions existing at control points within the field. Based on the results, farm personnel formulate a prescription request, which is forwarded via email or FTP to a central processing site, where the prescription is prepared. The latter is returned via email or FTP to on-side farm personnel, who can load it into a controller on a spray rig that directly applies inputs to the field at a spatially variable rate.
