Title: Optical fiber measuring device, gyrometer, central navigation and stabilizing system
Inventor: LEFEVRE HERVE
IPC: G01C19/72
Filed: 1990-11-16
Abstract: The invention relates to a fibre optic measuring device of the type in which the change in a measured parameter generates a phase difference between two waves in a SAGNAC ring interferometer (2).      Electronic means (7) comprise a processing system (9) delivering a signal depending on the measured parameter and electronic means (12) controlling the phase modulator (4).      The electronic means (12) produce a control signal for the modulator determined in such a way that the phase difference 54m which it produces between the counter-propagating waves periodically takes the following four successive values: .delta.~1 = .delta.o                    .delta.~3 = a~o .delta.~2 = - .delta.o        .delta.~4 = - a~o where ~o is a constant phase shift and it depends on a, and a is a positive constant satisfying the condition: cos~o = cosa~o.      The gain of the channel for controlling the modulation is kept constant by producing a signal depending on the said gain by exploiting the four values x1, x2, x3, x4 delivered in response to a period of the modulation signal according to the expression (x1 + x3) -(x2 + x4), the said signal acting on the modulator in such a way as to keep the gain constant.

Title: Photopolymer printing plates having a dimpled printing surface
Inventor: CHIANG ALBERT C
IPC: G03F5/20
Filed: 1991-02-20
Abstract: ABSTRACT            The present invention provides a photopolymer printing plate for use in  flexographic printing wherein the photopolymer relief structure is composed of printing characters  of  uniform printing  height,  the  planar printing  surfaces  of  which  characters  contain  a plurality of well-like dimples or depressions present at a density within the range of from about 25 to about 500 depressions per linear  inch of planar printing surface.  The invention also provides a process for preparing  such  photopolymer plates  by  exposing  the photopolymer  layer  to  actinic  radiation through  a photographic  mask  containing  optically  transparent areas and optically opaque image areas, the transparent areas of said mask characterized by the presence of a plurality of opaque discrete dots or other geometric shapes present at a density of from about 25 to about 500 dots per linear inch.  These dots serve to block a portion of the light passing through the transparent areas of the mask thereby forming discrete regions in the underlying photopolymer layer which are not exposed or are only partially exposed.  Upon development of the plate, the regions of the photopolymer layer underlying the dot pattern are removed resulting in the formation of a plurality of depressions in the relief planar surface of the exposed portions of the photopolymer layer.            Upon the application of printing ink to the relief printing surface of the plates of this invention, the depressions on the relief surface act as ink reservoirs resulting in  the  application   of a  more   even distribution  of  ink  to  surfaces  to  be  printed, particularly where large solid areas are printed.

IPC: H03F1/32
Filed: 1991-07-08
Abstract: ABSTRACT OF THE DISCLOSURE         The  invention  relates  to  a  process  for compensating nonlinearities in an amplifier circuit. An input signal s(t) is amplified to form an output signal y(t) using an amplifier circuit (2)  (power amplifier) subject  to  nonlinearities.  In  accordance  with  the invention,  a  predistortion  filter  (1)  is  connected upstream of the amplifier circuit  (2).  An aggregate signal   is formed in said filter from the input signal s(t) and a predistorted signal x(t) fed back from the output of the predistortion filter, and integrated with respect to time. The predistorted signal x(t)  is fed to the amplifier circuit subject to nonlinearities.  In this case,  the prescribed number n+l of coefficients k0, ..., kn is determined in accordance with the model   so that for a given input signal x(t) of the amplifier circuit the output signal determined in accordance with the model  is  essentially  identical with  the  output signal y(t) of the amplifier circuit.

Title: Method and apparatus for echo cancellation of a multicarrier signal
Inventor: CIOFFI JOHN M
IPC: H04B3/23
Filed: 1992-01-29
Abstract: ABSTRACT           When the transmitter and receiver of a duplex multicarrier modem are connected to a two-wire line, echoes of the transmitted signal are reflected back into the receiver by mismatches between the output impedance of the modem and the input impedance of the line. These echoes are cancelled by an echo emulator which operates on samples of the transmitted signal. The parameters of the emulator are adapted by correlating, in the frequency domain, the transmitted data with the received signal. A specialized phase-locked loop, which uses a unique phase detector, tracks both frequency offset and phase of the far echo separately from the adaptation of the emulator parameters. Initial trainng of the canceller is performed with a simple cyclic training signal that allows the use of efficient fast transforms.
