Patent CA-2241408-C (CA)
Inventor: LIMBERG ALLEN LEROY

Abstract: A method for detecting when a digital television signal is accompanied by co-channel interfering NTSC signal of substantial amplitude is described for use in a digital television receiver. The video portion of any co-channel interfering NTSC signal is synchrodyned to baseband, for generating an in-phase demodulation result including first artifacts of the digital television signal, and for generating aquadrature-phase  demodulation result including second artifacts of the digital television signal. The quadrature-phase demodulation results are phase shifted by 90° at frequencies in a prescribed frequency range before being linearly combined with the in-phase quadrature-phase demodulation results, to generate a linear combining result substantially free of the first and second artifacts of the digital television signal in the prescribed frequency range. An indication that the digital television signal is accompanied by co-channel interfering NTSC signal of substantial amplitude is generated by detecting whenever the amplitude of the linear combining result exceeds a prescribed value.

Title: Radio environment analysis apparatus
Inventor: KUWAHARA YOSHIHIKO
IPC: H04W24/08
Filed: 1999-06-01
Granted: 2002-10-15
Abstract: A radio environment analysis apparatus includes a receiver and signal processor. The receiver receives a signal modulated by phase shift keying (PSK) using a pseudo noise (PN) code sequence by an array antenna at a plurality of fixed points on the plane, converts the received signals into intermediate frequencies or demodulated signals, and outputs them.      The signal processor processes a signal output from the receiver to analyze the arrival angle, delay time, and relative power of the signal incoming to the receiver.      The signal processor has a plurality of normalization units, first estimation unit, arithmetic unit, and second estimation unit. The normalization units individually normalize signals from the receiver and output them as a normalized signal group. The first estimation unit calculates a covariance matrix, and estimates the arrival angle of each incoming signal.      The arithmetic unit calculates a weight of the array antenna for suppressing incoming signals except for an incoming signal having the estimated arrival angle, and calculates the product of the weight of the array antenna and the normalized signal group. The second estimation unit calculates a covariance matrix and estimates the delay time and relative power.

Filed: 2000-03-27
Granted: 2004-07-13
Abstract: A process for extracting a component from liquids using dense phase gases or supercritical fluids (dense phase solvent). The process contacts a liquid and the dense phase solvent in a rotating mixer to dissolve a desired fraction into the dense phase solvent to form a loaded solvent. Furthermore, the mixer separates the loaded solvent from the remaining raffinate. Then the rotating mixer discharges the loaded solvent and raffinate. Decreasing pressure on the loaded solvent converts the loaded solvent into a gas and the desired fraction to liberate the desired fraction from the gas.
