Abstract: A method of facilitating the contracting of agricultural products using the Internet is used for providing buyers and sellers with real time information relating to the type and amount of agricultural products available for contract. The invention includes a relational database for the storage and retrieval of information. One or more end use buyers can store information in the database relating to a desired type and quantity of agricultural products. Agricultural producers, such as farmers, can view listings of agricultural products desired and the system can facilitate the contracting between the buyers and producers for the agricultural products. The system can display in real time the quantity and types of agricultural products under contract and available for contract. The system can manage delivery preferences, quality data and determine contract pricing based on these criteria.

Abstract: An aircraft vent door system includes a vent door for a vent on an aircraft door. A cam, having a groove, is disposed on the vent door. The system also includes a movement assembly, which includes a roller disposed within the groove, and a lever coupled to the movement assembly. A portion of the lever extends beyond and proximate to the perimeter of the vent door. A second lever may also be attached to the aircraft door. The first lever pivots in response to the movement of the movement assembly, and urges the second lever to pivot. The second lever, in turn, urges the vent door open, thereby overcoming the sticking effect of, for example, built up ice or other obstructions.
Abstract: Two acyltransferases are provided, suitable for use in the manufacture of microbial oils enriched in omega fatty acids in oleaginous yeast (e.g., Yarrowia lipolytica). Specifically, the genes encoding phophatidylcholine-diacylglycerol acyltransferase (PDAT) and diacylglycerol acyltransferase (DGAT2) have been isolated from Y. lipolytica. These genes encode enzymes that participate in the terminal step in oil biosynthesis in yeast. Each is expected to play a key role in altering the quantity of polyunsaturated fatty acids produced in oils of oleaginous yeasts.

Abstract: The invention is a hermetic via in a ceramic substrate that is comprised of noble metal powder in a glass-free paste that contains an admixture of a particulate phase of niobium pentoxide. The electrically conductive platinum provides excellent electrical conductivity while the niobium pentoxide phase prevents shrinkage of the paste during thermal processing and binds to both the ceramic and the noble metal particulates in the via, thus maintaining a hermetic seal around the via.

Abstract: A cassette for supporting a film during a gaseous vapor deposition process includes a central shaft having first and second end plates. A rib on each end plate forms a spiral groove able to accept an edge of a film. Each rib has a cross sectional configuration having substantially linear major edges, a predetermined width dimension and a predetermined average thickness dimension, and a width-to-thickness aspect ratio of at least 2:1. The rib could be substantially rectangular with an optional flow spoiler at the free end or substantially wedge-shaped. The interspoke spacing between end plates is at least three hundred millimeters (300 mm) and is also greater than the width dimension of a film substrate at a gaseous deposition temperature. The width dimension of each rib is between about 0.5% to about 2.0% of the interspoke spacing.

Abstract: A system and method for improving the processing of communications signals received in the presence of narrowband interference signals. The received communications signals are time sampled and transformed into a series of spectral terms in the frequency domain that are then evaluated to identify narrowband interference signals. The identified narrowband interference terms can be calculated to a value that will optimize the corrupted spectral terms resulting from the communication, and an inverse transformation can be used to generate a time domain signal that is free from interference.

Abstract: A high voltage analog switch operable by a binary signal is implemented in a low voltage semiconductor process. The switch has three parallel circuit paths, with each path comprising at least three series connected transistors. Control signals are selectively applied to the control terminals of the transistors to control the switch and selectively turn on or turn off each of the three circuit paths depending on the input voltage range, so that the breakdown voltage of all of the transistors is never exceeded in any mode of operation.

Abstract: A vapor deposition apparatus includes an insert within which a material is deposited on the surface of a film. A cassette includes end plates each having a rib that edgewise receive a spiral wrapping of a film at least 300 mm wide. Spaces between turns of the wrapping define a gas flow channel and spaces between adjacent turns of one rib define inlet openings that communicate with the channel. Each rib has a predetermined width dimension, a predetermined average thickness dimension, and a width-to-thickness aspect ratio of at least 2:1. The spacing between end plates is at least 300 mm and is also greater than the film width at deposition temperature. The width dimension of each rib is between about 0.5% to about 2.0% of the end plate spacing. A diverging flow director contacts one end plate to directing gaseous fluid toward the inlet openings in that end plate.

Abstract: A high voltage current source and a voltage expander implemented in a low voltage semiconductor process. The voltage expander extends the operating voltage range of a stack of transistors to multiple times a supply voltage Vdd at the output node of the stack without exceeding the breakdown voltage of any of the transistors in the stack. The voltage expander uses a diode and a voltage divider to detect the output node voltage changes and generates a plurality of voltages that control the gate voltages for the stack of transistors. A high voltage wide swing current source utilizes a transistor to set the output current and the voltage expander to extend the output voltage range of the current setting transistor. An additional transistor and another current source ensure that the output current is constant throughout the entire output voltage range between about 0 V and multiple times the supply voltage Vdd.

Abstract: The invention relates to a light emitter, such as an LED sealed with a resin, in particular, an LED wherein irregularities in a surface of a sealing resin can be formed through a simpler process in order to improve the light output efficiency of the LED. The LED is an LED wherein a liquid sealing resin is mixed with a solid transparent resin different from the sealing resin in specific gravity and subsequently the mixture is injected into a package into which an LED chip is integrated and then cured, thereby sealing the chip, characterized in that the solid transparent resin is fixed to the sealing resin to be partially naked to the sealing-resin-side surface of the LED through which light from the LED chip is emitted to the outside, and be partially embedded in the sealing resin, thereby being projected into the form of convexes. This LED is used for an LED displayer, an LCD backlight source, a lighting device or the like.
