The system also includes at least one port defined in at least one of the slat, main wing element, and flap. In addition, the system includes at least one fluidic device operable to regulate fluid flow into and out of the at least one port to control boundary layer flow over at least one of the slat, main wing element, and flap.

Abstract: A system and method for dissipating vortices that form at the wingtips on aircraft and from other airfoils. A jet air stream is discharged in a location at or proximate to the outer end portion of the airfoil into the vortex flow, and the jet air stream is moved cyclically back and forth. The cyclic movement can be at lower or higher frequencies to alleviate at least in part intensity of the vortex or accelerate instability of the vortex which leads to vortex dissipation.

Abstract: A system and method for controlling boundary layer flow over an aircraft wing are provided. The system includes at least one wing element, and a plurality of ports defined in the wing element and in fluid communication with one another. The system also includes at least one fluidic device operable to continuously ingest the fluid through at least one of the ports and eject the fluid out of at least one other port to control boundary layer flow of the fluid over the wing element.

Abstract: A double oven crystal oscillator (DOCXO) is disclosed which is highly stable by incorporating means to reduce the effects of ambient pressure changes on the frequency of the oscillator. The oscillator crystal is mounted in a temperature controlled inner oven to reduce the effects on the frequency stability of the oscillator. The oscillator circuitry and all circuitry associated with the inner oven is mounted in good thermal contact with the inner oven. A Faraday shield at ground potential is placed over the oscillator circuitry to minimize the effects of stray capacitance between the oscillator components and the case wall of the inner oven. The effects of minor deformations in the case walls within the oscillator caused by ambient pressure changes and other factors causing pressure changes are thereby greatly minimized.

Abstract: A lightweight, portable table comprising a unitized table top member and legs secured to the table top member. The unitized table top member includes table top and bottom elements and a rigid support member. A hardened foam body is joined to the top and bottom table elements and is formed around the support member in sufficient volume to support the support member within the table top member. A lightweight core element is positioned within the table top member joined to the hardened foam body. The table advantageously requires few parts and is economical to manufacture yet is sturdy and easily transported.

Abstract: A remotely operated cutting mode shifting apparatus for use with a decoking tool of the type in which the cutting mode is changed by rotation of a diverter valve plate, has a shifter body adapted for mounting to the decoking tool and a control rod for engaging with the diverter valve plate. It includes a mechanism within the shifter body for rotating the control rod to drive the diverter valve plate to shift the cutting mode of the decoking tool upon release of cutting fluid pressure from the tool.

Abstract: Disclosed is a waxy barley pearl containing high levels of viscous beta-glucan. Also described are the methods to produce this product.

Abstract: A method and apparatus for efficient power amplification of a wideband signal with a correspondingly wide modulation bandwidth includes an envelope detector (220), an adaptive split band modulator (270), and a power amplifier (260). The adaptive split band modulator (270) amplifies the low frequency components using a class S modulator (760), and amplifies the high frequency components using a class B amplifier (750). The power supply of the class B amplifier (750) is adaptively modified as a function of the amplitude of the signal that it amplifies. In this manner, the class B amplifier (750) operates at a higher efficiency.

Abstract: A pillow designed and adapted to cover the back portion of a user's head such as a mechanic or workman, said pillow being secured to user's head by means of an elastic or adjustable strap thereby freeing up the use of both of the user's hands when the user is moving about on his back beneath a vehicle or the like, with the filling of the pillow being removable to facilitate the cleaning or washing of the pillow cover and strap, and with the section of the pillow which lays adjacent to the user's head containing means to attach a cap to cover the user's head which cap may also be provided with a visor or the like to protect the eyes of the user.

Abstract: The present invention is a technique for operator entry of a time program into a programmable device. An operator adjustable input device having associated time indicia is employed to enter a time signal indicative of a time a selected time. A manual control state input device enables selection of one a control state. When the programmable device is in a program mode the selected control state is stored in a program memory at a location corresponding to the selected time. This program memory stores a program of control states for particular times. When in a control mode a clock signal indicative of the current time permits recall of the control state for the current time, thus permitting control in accordance with the recalled control state. In accordance with the preferred embodiment the programmable device is an electronic thermostat.

Abstract: A flanged hollow shroud that is adapted to be sealingly secured to an aperture bulkhead as used, for example, in a vehicle to separate an engine compartment from a passenger compartment, is used to telescopically receive the mating end of a pair of male and female connectors having mating electrical terminals therein. At least one of the connectors, such as the male connector located on the engine compartment side of the bulkhead is sealingly fixed to the shroud and the electric terminals therein are also sealed adjacent to their outboard end within the respective cavities supporting these terminals.
