Title: Processable conductive polymers
Inventor: JASNE STANLEY J
IPC: H01B1/12
Filed: 1986-11-20
Granted: 1992-03-17
Abstract: ABSTRACT OF THE DISCLOSURE         Processable conductive polymers prepared by an oxidative polymerization are disclosed.  A monomer which is oxidatively polymerizable into an electrically conductive polymer is polymerized with the aid of a chemical oxidizing agent in a reaction medium containing a dispersed phase of a polymeric counterion having anionic surface character.  The polymeric counterion, which is in affiliation with the oxidatively polymerized polymer, confers processability to the conductive polymer material.  The oxidative polymerization method enables the production of a processable polymeric dispersion which is coatable to a useful electrically conductive film.

Title: Magnetic resonance imaging method, and device for determining the pulse angle of an r.f.electromagnetic pulse

Granted: 1991-02-12
Abstract: ABSTRACT            Magnetic resonance imaging method, and device for determining the pulseangle of an r.f. electromagnetic pulse.     The known magnetic resonance imaging method of determining the r.f. power or pulse angle of an r.f. electromagnetic 90°-pulse or 180°-pulse has the drawback that the measurement inaccuracy is often high, that the experimentation time is comparatively long and that its use is limited to r.f. electromagnetic 90°-pulses or 180°-pulses only.  In order to mitigate these drawbacks, it is proposed to determine the pulse angle of an r.f. electromagnetic pulse having a pulse angle a from two out of five echo resonance signals, including one stimulated echo resonance signal, generated by means of three r.f. electromagnetic .alpha.°-pulses, a having an arbitrary value (calibration phase), after which any .beta. can be adjusted by adaptation of the applied r.f. power.

Abstract: INSPIRATION OXYGEN SAVER            Abstract of the Disclosure A  reliable,   pulse-flow  supplemental oxygen  apparatus  for  alleviating  respiratory ailments  is  provided  which  yields  substantial savings in oxygen while giving the patient the physiological equivalent of a prescribed continu-ous stream of oxygen.   The apparatus preferably includes a demand oxygen valve operated in a pulse mode by means of electronic control circuitry which, through an appropriate sensor, monitors the patient's breathing efforts and gives a variable "custom tailored" pulse volume of oxygen to the patient during the very initial stages of each inspiration.   Pulse volume variability is based upon a measured parameter characterizing at least a part of one and preferably a plurality of the patient's preceeding breaths; advantageously, the elapsed  time  interval  of  the  patient's  three preceding breath cycles is measured to effectively measure breath rate.  These breath-characterizing parameters, together with data characterizing the prescribed continuous oxygen flow to be matched, enable the apparatus to give the desired "on the go" dose variability.   The apparatus is also designed to revert  to conventional,  continuous-flow operation upon a power failure or circuit malfunction, and for thus purpose a specialized dual flow control restrictor valve is provided in the form of the invention designed for hospital use.   In the event of abnormally low or high breath rates on the part of the patient,  the device automatically delivers a relatively  long continuous pulse,  then stops to again sample the breath rate.  If the rate is normal, the usual pulse flow operation is resumed;  if the rate remains  abnormal,  the  long  pulse  volume-rate sampling is repeated.   Actual tests with the apparatus hereof demonstrate an oxygen saving of over 50% as compared with continuous flow regi-mens.

Title: Interactive television and data transmission system
Inventor: MARTINEZ LOUIS
IPC: H04N7/173
Filed: 1987-05-14
Granted: 1997-08-19
Abstract: A spread spectrum system provides bidirectional digital communication on a vacant television (TV) channel for simultaneous use by more than 75,000 subscribers using time and frequency division multiplex signals locked to horizontal and vertical sync pulses of an adjacent channel Host TV station.  The system, whose operation is analogous to a radar system, comprises: (1) the Host TV station to send down-link sync and data pulses to subscribers during the horizontal blanking interval (HBI), (2) subscriber "transponders" which detect those signals and transmits up-link "echo" data pulses only during the HBI to eliminate interference to TV viewers, and (3) a central receiver which also uses the host TV sync pulses to trigger range gates to detect the up-link data pulses.  In a preferred embodiment the central receiver employs directional antennas to determine direction to transponders and to define angular sectors partitioning the service area into pie-like "cells" which permit frequency re-use in non-contiguous sectors (like cellular radio). The system thus operates like a radar to measure elapsed time between receipt of TV sync pulses and receipt of transponder response pulses and measures bearing to transponders to thereby determine the location of fixed or mobile subscribers as well as provide data links to them.  Transponders may share user's existing TV antenna or may operate on cable TV and could be packaged as "RF modems" for personal computers, as transceivers for mobile or portable use, or they may be integrated with a TV receiver to provide "interactive television".

Title: Method for determining the heading of an aircraft
Inventor: KLEINSCHMIDT MICHAEL
IPC: G01C21/16
Filed: 1987-08-25
Granted: 1990-12-04
Abstract: Abstract of the Disclosure                   _ A method is disclosed for determining the heading of an aircraft which is equipped with both an inertial navigation system and a device capable of receiving navigation satellite signals and computing the aircraft's position, speed and acceleration therefrom. While the aircraft is still on the ground and before flight operations begin, an initial alignment of the inertial navigation system with an earth-fixed coordinate system is performed, and during this alignment, data corresponding to the initial attitude of an aircraft-fixed coordinate system relative to the earth-fixed coordinate system is also determined and stored.  Thereafter, during flight operations, the acceleration vector of the aircraft relative to the aircraft-fixed coordinate system is measured by the inertial navigation system and then trans-posed into a coordinate system which has been horizontally aligned with the earth-fixed system using the initial attitude data.  A second acceleration vector, corresponding to the acceleration of the aircraft in the earth-fixed system, is computed using the navigation satellite system. The aircraft's heading is then determined by computing the difference, i.e., the angle between, the two acceleration vectors.  The method is amenable to Kalman filtering techniques and, by eliminating the need for highly accurate gyroscopes or magnetic compasses, permits rapid and highly accurate heading determinations to be made at much less expense.

Polycationic buffers may be used for both analytical and preparative purposes and result in a nearly two-fold improvement in both separation and resolution of the nucleic acid bands.  Furthermore, the use of polycationic buffers reduces the electrophoresis time by a factor of about three due to the low conductivity of the buffers.
