Abstract: Methods for transformation of maize with nucleic acid sequences of interest are disclosed. The method involves subjecting immature zygotic embryos or Type I callus to high velocity microprojectile bombardment. The method is capable of producing transformed maize lines of commercial importance and their hybrid combinations.

Abstract: DNA sequences optimized for expression in plants are disclosed. The DNA sequences preferably encode for an insecticidal polypeptides, particularly insecticidal proteins from Bacillus thuringiensis. Plant promoters, particular tissue-specific and tissue-preferred promoters are also provided. Additionally disclosed are transformation vectors comprising said DNA sequences. The transformation vectors demonstrate high levels of insecticidal activity when transformed into maize.

Abstract: An adaptive gate drive for an inverter includes control circuitry having a Field Programmable Gate Array (FPGA) and includes power circuitry having a plurality of FETs for operating a switching device, such as a Trench Gate Insulated Gate Bipolar Transistor (IGBT device). The control circuitry provides switching signals for operating the switching device. In addition, the control circuitry receives signals of output current of the IGBT device, temperature of the IGBT device, and DC link voltage. The FPGA has a plurality of operating points stored therein. Each operating point has corresponding parameters for a control signal that is used to control the turn-on or turn-off behavior of the IGBT device. During operation, the control circuitry compares the measured current, voltage and temperature operating points stored in the FPGA and sends the corresponding parameters to the gate drive circuit.

Abstract: A method of estimating rotor resistance by calibrated measurement of stator temperature is provided. The temperature of the stator winding may be monitored using a suitable device (thermistor, RTD etc). This temperature signal is used to “look up” the correct value of Rr for the current temperature. The “look up” characteristic is a calibrated table, whose values are learned during a prolonged test whereby actual (measured) motor torque is controlled to a correct demanded value by adaptation of the Rr parameter, as the motor temperature varies from cold to hot. The stator temperature feedback during the test provides the X-axis values of the look up table, and the correctly adapted Rr value provides the Y-axis values.

Abstract: The present invention relates to methods for reducing the risk associated with the administration of opioid analgesics in patients diagnosed or undiagnosed with respiratory illness by administering an analgesic composition comprising a sub-analgesic dosage of a ?-opioid agonist selected from the group consisting of morphine, fentanyl, sufentanil, alfentanil, oxymorphone and hydromorphone, or a pharmaceutically acceptable salt thereof, and a sub-analgesic dosage of oxycodone which is a ?2-opioid agonist or a pharmaceutically acceptable salt thereof.

Abstract: A direct sequence spread spectrum approach to wireless video transmissions is utilized. This approach provides a lowered spectral power density and also can provide scrambling of the video signal. By providing lower spectral power density the transmitter portion of the invention can operate at higher radio frequency output power levels while remaining in compliance with government regulation for unlicensed use. For example, in the United States, the Federal Communications Commission Part 15 rules allow for higher total conducted output power as long as the spectral power density is limited to +8 dBm for any 3 KHz bandwidth within the allocated band.

Abstract: An apparatus and a method of cooling a piston by passing a stream of lubricating oil against the underside of the piston and more specifically by providing an enclosed reservoir space between the engine cylinder wall and the side wall of the piston formed by a depression in the piston and providing a passageway in the piston aimed to direct oil to a desired location on the undersurface of the piston.

Abstract: An oil jet nozzle (24) has an extruded body (48) with an integrally formed tab (64). The tab is constructed to be snugly received in an oil groove (32) situated along the bearing seat (34) in the crankshaft journal of the engine block. The groove which receives oil from an oil gallery (42) passes some of the oil through to the nozzle which sprays the oil from two outlets (46) to two adjacent pistons (14) for cooling thereof.

Abstract: This application concerns a leaf type spring for closing valves in a cylinder head of an internal combustion engine. Specifically, the leaf spring has an edge base which is attached to the cylinder head and a cantilevered unsupported portion which extends therefrom. The unsupported portion is bifurcated to form two arms, each arm engaging a valve in a manner biasing it towards its closed operative position and yieldably permitting the valve to be moved toward its open operative position.

Abstract: The present invention provides a method for reducing, or preventing, bone marrow hypoplasia in a patient at risk of, or having, same. To this end, when a glutathione intracellular stimulator is administered to such a patient, the risk of bone marrow hypoplasia is reduced or prevented. In an embodiment, the composition for stimulating the intracellular glutathione levels comprises L-2-oxothiazolidine-4-carboxylate.

Abstract: The present invention relates to methods for providing nutritional requirements to a patient having a chronic inflammatory reaction by administering to the patient an enteral composition that has a sufficiently reduced arginine content to reduce the nitric oxide formation in the patient. In an embodiment, the composition includes less than approximately 0.2% of the total calories as arginine.
