Title: Residual echo elimination with proportionate noise injection
Inventor: GENTER ROLAND
IPC: H04B3/23
Filed: 1991-07-30
Granted: 1999-07-13
Abstract: Residual echo from an echo canceller circuit is reduced by a variable attenuator that operates in response to a processing circuit which determines and adjusts an attenuation factor.  The attenuation factor is determined by comparing relative levels of the send input signal, the receive input signal, and the error signal remaining after removal of an expected echo signal from the send input signal.  The variable attenuator provides linear power attenuation of the error signal in order to reduce transmission of the residual echo signal and to eliminate the perception of coupling and decoupling of the telephone connection which occurs in known echo cancellers employing center clipping.  A noise injection circuit provides a noise signal that is injected into the transmitted signal in inverse proportion to the attenuation of the error signal in order to provide a constant noise level in the transmitted signal as the error signal is variably attenuated.

Title: Methode de selection de superagonistes, antagonistes et de superagonistes d'hormones dont le complexe de recepteurs incluent le gp130
Inventor: SAVINO ROCCO
IPC: C07K19/00
Filed: 1994-06-23
Granted: 2004-10-26
Abstract: Il s'avère que les ligands du groupe de cytokines semblables à l'interleukine 6 (Il-6), à savoir l'oncostatine M (OSM), le facteur inhibant les cellules leucémiques (LIF), le facteur neurotrophique ciliaire (CNTF) et l'interleukine 11 (IL-11), induisent la formation d'un complexe récepteur dont fait partie la molécule de membrane gp 130. Par conséquent, on peut formuler l'hypothèse que deux surfaces différentes de la protéine (dans cette classe d'hormones), appelées site 1 et site 2, se lient à deux molécules différentes: le site 1 se lie au récepteur spécifique et le site 2 à la gp 130. On peut identifier ces sites et isoler des variantes présentant, par rapport à l'hormone sauvage, une plus forte affinité pour le récepteur spécifique (super-agonistes et super-antagonistes) ou une affinité réduite ou nulle pour la gp 130 (antagonistes et super-antagonistes). Le dessin représente la structure pHen DELTA  hIL-6 et la production de particules phasmidiques utilisables dans la sélection d'agonistes de l'interleukine 6.

Granted: 2007-01-09
Abstract: A finite field multiplier in GF2mn is formed from a pair of m celled shift registers and an m celled accumulating cell. Logical connections are established to generate grouped terms in respective cells of the accumulating cell upon retention of the vector of the subfield elements in each shift register. Each cell contains a subfield element in the form of an n-tuple and the logical connections perform arithmetic operations in accordance with the inherent subfield arithmetic to provide an n-tuple in each cell of the accumulating register. A product of two vectors can be obtained in m clock cycles. By mapping between registers, squaring of a vector can be obtained in one clock cycle.

Title: Process for hydrophilicization of hydrophobic polymers
Inventor: DING NI
IPC: C08J7/056
Filed: 1996-01-15
Granted: 2002-10-01
Abstract: A process for rendering the surfaces of polymeric plastic or rubber materials, which are intrinsically non-polar or only slightly polar, and hydrophobic, polar or more polar, and hydrophilic, so that amine-containing functional groups, and ultimately, a durable tenaciously adhering, slippery polyurethane or polyurethane-urea hydrogel coating may subsequently be applied to the polymer surface, is disclosed.  The process involves dual plasma-treatment of a polymeric plastic or rubber substrate material; the first treatment being with an oxygen-containing plasma gas, to affix hydroxyl, carboxyl and carbonyl groups to the substrate surface, thereby rendering the surface more polar and activated; and the second treatment being with a nitrogen-containing plasma gas, to affix amine and amino groups to the substrate surface to make it more hydrophilic and reactive toward terminal isocyanate groups of a polyurethane or polyurethane/urea prepolymer adduct intermediate tie-coat which is subsequently applied to the substrate surface and then converted to a tenaciously adhering, slippery hydrogel coating. The process is especially suited to the hydrophilicization of intrinsically non-polar and hydrophobic polymeric plastic materials, such as polyethylenes, nylons-11 and nylons-12.

Title: Distortion compensation control for a power amplifier
Inventor: MCNICOL JOHN DUNCAN
IPC: H03F1/32
Filed: 1997-07-23
Granted: 2001-10-09
Abstract: A control arrangement and method for controlling a gain and phase adjuster used for controlling the gain and phase of a compensation signal for compensating for the distortion produced by a power amplifier is disclosed.  The control arrangement makes use of a reference signal, of known frequency, which is amplified along with the desired carrier signals.  The reference signal component of the amplified signal is then isolated and a comparison is made, either with the actual reference signal, e.g., by a QAM demodulator, or alternatively with the known frequency of the reference signal, e.g., by a FM discriminator, in order to determine the differences in gain and in phase of the reference signal component of the amplified signal in comparison with the reference signal.  For example, a QAM demodulator is used for producing a first difference signal indicative of the phase switch difference, and a second difference signal indicative of the gain switch difference. These signals are then correlated with the signal envelope of the main signal in order to produce signals indicative of the sign and magnitude of the control signals used to adjust the gain and phase adjuster in a feed back loop.

Abstract: A fixture for installing a flexible wire mesh grip over an elongated cable includes a base having spaced opposite ends and an internal cavity extending longitudinally therebetween. The spaced opposite ends define respective first and second passages opening into the internal. cavity. The internal cavity has a cross-sectional size larger than that of a tubular body of the grip in a compressed non-gripping condition to accommodate the presence of the tubular body in the compressed non-gripping condition and of an annular collar secured on one end thereof within the internal cavity. The internal cavity and first and second passages of the base have respective cross-sectional sizes larger than that of the cable to permit insertion of the cable therethrough. The cross-sectional size of at least one of the first and second passages of the base is smaller than that of the internal cavity and of the annular collar and the tubular body in the compressed non-gripping condition so as to define an interior shoulder on the base that at least partially surrounds the one passage and against which the annular collar secured on the one opposite end of the tubular body can be placed to facilitate moving the other opposite end of the tubular body toward the annular collar and one opposite end to convert the tubular body from an expanded gripping condition to the compressed non-gripping condition with respect to the cable and thereby facilitate movement of the cable through the passageway of the tubular body and thus relative to the grip.
