Title: Spectral distortion monitor for controlling pre-distortion and feed-forward linearization of rf power amplifier
Inventor: GOMEZ JASON N
IPC: H03F1/32
Filed: 2001-02-14
Abstract: A carrier cancellation combiner, and pre-distortion and feed-forward loops of an RF power amplifier are controlled to minimize IMD components at the output of the RF amplifier, by a spectral distortion measurement scheme that performs Fast Fourier Transform (FFT)-based spectral power measurements at a "reference' signal port (associated with the RF input signal), and a plurality of "test' signal ports (associated with various monitoring locations of the amplifier). Signals extracted from the control and test ports are downconverted to baseband, bandpass filtered, digitized and stored as a spectral "snapshot' of the entire band of the signal infrastructure of the amplifier. A digital signal processor-based controller processes the buffered data to produce averaged FFT's of the data extracted from the reference and test ports and thereby provide spectral information for each sampled signal set. The FFT for the control data is processed to establish a baseline, with which the FFTs for the test data are compared, to generate adjustment signals for control parameters through which IMD components introduced by the amplifier may be minimized.

Title: Fluid control circuit
Inventor: PARKER RAYMOND GEORGE
IPC: G01M5/00
Filed: 1982-02-03
Abstract: Fluid control circuit for controlling the pressure applied by jacks (12) to an article such as an aircraft wing undergoing testing. Fluid supply lines (18, 20) carry hydraulic fluid to and from the jacks (12) under control of a main control valve (23). Locking means (16) in the form of cutoff valves (25, 26) are provided to close the supply lines (18, 20) to fluid flow if a fault condition is detected. The cutoff valves (25, 26) are pilot operated and normally hold lines (18, 20) open. Pilot control valve (31) controls the supply of pilot fluid to the cutoff valves (25, 26). Dump lines (37, 38) are opened to pressure relieving fluid flow when dump control valves (39, 40) are open. Bleed control valves (41, 42) control the rate of such pressured relieving flow. Auxiliary valves (47, 48) prevent leakage flow back through main control valve (23) when the dump lines (37, 38) are open.

Abstract: "CARPET PRODUCT WITH INTEGRAL       BALANCING LAYER"         Abstract of the Disclosure An improved carpet product includes a pile fabric layer and a stabilizing layer adhered to the back of the pile fabric layer to provide dimensional stability against concentrated stresses exerted against the upper surface of the carpet. A balancing layer disposed below the stabilizing layer has thermal response and moisture absorption characteristics selected for compatibility with the pile fabric layer. When the carpet product is exposed to temperature extremes or changes in ambient humidity, stresses exerted by the expansion or contraction of the pile fabric layer create a bending moment around the stabilizing layer. However, the balancing layer creates comparable stresses on the lower side of the stabilizing layer and exerts an equal-but-opposite bending moment which balances the moment exerted by the pile fabric layer. The resulting carpet product exhibits enhanced flatness and floor hugging characteristics when subjected to temperature extremes or changes in the ambient humidity.
