Title: Asynchronous communications system
Inventor: HUI YU N
IPC: H04B10/278
Filed: 1986-05-12
Granted: 1991-01-02
Abstract: Abstract of the Disclosure Methodology, and associated circuitry, for encoding and decoding  signals  utilize  combined  time-signal  path  diversity techniques that trade-off bandwidth for autonomy of communications and simplified signal processing, thereby improving reliability. Transmitter (800) processes an incoming data stream by partitioning the stream into contiguous blocks.  Each block is encoded into a data frame for transmission over one or more paths comprising the medium interconnecting the transmitter and receiver. Frame encoding is effected by generating an array of pulses distributed in time as well as distributed across the paths.  Receiver (100) is generally arranged as a correlation detector in that the receiver only responds to the particular time-signal path pattern for which it is configured.  Sensors in energy transfer relation to the one or more paths  are  positioned  at  detection  points  on  the  paths  in correspondence to the time-space pattern of the receiver.   The outputs of the sensors are processed to produce a correlation signal at the given frame rate whenever the coded signal corresponding to the receiver configuration is propagating along the paths.

Granted: 1990-12-11
Abstract: ABSTRACT OF DISCLOSURE          The  invention  concers an  apparatus for washing cellulose, wherein the cellulose is conducted through between a rotary drum and a stationary shell encircling it,  in the form of a layer supported by the permeable mantle surface of the drum.          The principle of operation of the appratus is:  conducting washing  liquid  through  the  shell,   through  compartments located under the mantle surface of the drum and serving as washing  liquid  collectors,   and  through  a  valve  system composed of a  rotary part  associated with  the drum  and a stationary part placed thereagainst,  several times through the cellulose layer so that when the apparatus is operating the washing liquid at the same time moves in the direction opposite to the direction of rotation of the drum, stepwise, through the apparatus. It is essential in the invention that the valve system is composed of annular parts located at one end of the drum,  their radius substantially equalling that radius on which the compartments under the mantle surface of the drum are located from the shaft of the drum,  and that the part of the valve system rotating along with the drum comprises an aperture by which the ends of the compartments are joined to the valve system.  By this design,  the delay occurring in  the washing liquid transfer has been reduced and the controllability of the washing process has been im-proved.

Granted: 1991-03-12
Abstract: Abstract An active acoustic attenuation system is provided that actively models direct and feedback paths as well as characteristics of the secondary cancelling sound source and the error path on an on-line basis. The primary model uses a recursive least mean squares RLMS algorithm that is excited by the input acoustic noise and uses the residual acoustic noise as an error signal.  The secondary sound source or cancelling speaker and the error path are modeled by a second algorithm, particularly an LMS algorithm, that uses an additional auxiliary low level, random, uncorrelated noise source as an input signal.  The resulting overall system provides excellent attenuation of narrow band and broad band noise over a relatively wide frequnency range on a completely adaptive basis without direc-tional transducers.

Abstract: ABSTRACT OF THE DISCLOSURE              A pressure sensor assembly includes two spacedly positioned flexible supports which support an elongated rod,  with one end of the elongated rod contacting a pressure detector section on a disposable pumping cassette; the pressure sensor assembly can detect pressures in the cassette both above and below atmospheric (i.e., zero psig): when pressure changes in the cassette, the pressure detection section causes axial movement of the rod and the rod, in turn, flexes the two flexible supports.  Position detection means associated with one of the two supports monitors the flexural movement of the one support, providing an indication of the pressure within the cassette.
