Title: Receiver employing correlation technique for canceling cross-talk between in-phase and quadrature channels prior to decoding
Inventor: ROBERTS GLYN
IPC: H04L27/233
Filed: 1992-03-20
Abstract: ABSTRACT OF THE DISCLOSURE A receiver suitable for use in a radio-telephone system for recovering data from encoded, quadrature-modulated communication signals employs a feedback arrangement for suppressing cross-talk between the receiver's in-phase and quadrature channels to improve data recovery rates during decoding.  The receiver converts in-coming analog communication signals into in-phase and quadrature digital signals, which may have cross-talk components.  The receiver has an attenuator for subtracting feedback signals from the in-phase and quadrature digital signals to produce cross-talk-attenuated in-phase and quadrature digital signals, a decoder for decoding the cross-talk-attenuated in-phase and quadrature digital signals to generate first and second data output signals, and the above-mentioned feedback arrangement, which preferably employs a recoder and cross-correlation techniques, for generating the feedback signals.

Abstract: RD-21,551 METHOD OF PREPARING POLYMER SURFACES FOR SUBSEQUENT  PLATING THEREON AND IMPROVED METAL-PLATED PLASTIC              ARTICLES MADE THEREFROM                     Abstract of the Disclosure Method of modifying an aromatic polymer surface to improve adhesion of a metal layer thereon and to the articles produced therefrom.  The surface of the aromatic polymer such as polycarbonate, is nitrated by a contact with a nitrating solution such as a mixture of nitric and sulfuric acid and then hydroxylated by a contact with a hydroxylating solution such as ammonium hydroxide.  The hydroxylated surface is thus chemically modified to become hydrophilic.  The chemically modified surface is electrolessly plated with a primary metal layer.  A secondary metal layer is then electrolessly or electrolytically applied on top of the primary metal layer until a metal layer of a desired thickness is attained.            The present invention further discloses articles such as an EMI shielded enclosure or a printed circuit board having metal layers as an EMI shield or a conductive metal trace pattern respectively.

Abstract: Devices and methods are disclosed for moving charged molecules through a medium by the application of a plurality of electrical fields of sufficient strength and applied for sufficient amounts of time so as to move the charged molecules through the medium. The devices although preferably small in size, preferably generate large numbers (100 or more) of electrical fields to a movement area which preferably contains a liquid buffered or gel medium.  Mixtures of charged molecules are pulled through the gel by the force of the electrical fields. The fields are preferably activated simultaneously or sequentially one after another at various speeds to create complex force field distributions or moving field waves along the separation medium. Charged molecules capable of moving quickly through the gel will be moved along by the faster moving field waves and be separated from slower moving molecules. The fields can be activated by computer software and can be used to move molecules away from and toward each other to obtain rapid and complex chemical synthesis, sequencing or reaction protocols.
