Abstract: Abstract of the Disclosure SPACECRAFT ATTITUDE CONTROL USING COUPLED THRUSTERS   An  attitude  control  system  for  a  three-axis controlled  spacecraft  (1)  in  which  the  location  of thrusters causes significant cross-coupling torques.  A thruster   command   conditioning   electronics   module (TCCEM)  (3)  is  positioned  between  the  conventional roll, pitch, and yaw loop controllers (41-43) and the thrusters    (61-63).     The    TCCEM    (3)    converts spacecraft-axis-based torque requirement signals  (TDX, TDY, TDZ) emanating from the loop controllers  (41-43) into scalar quantities (UL, UH, UN) that are input to thruster modulators  (51-53)  that  turn on one or more thrusters of the thruster pairs (L,M,N),  The TCCEM (3) causes the spacecraft  (1)  attitude to be adjusted as commanded by the torque requirement signals (TDX, TDY, TDZ)  despite the presence of the cross-coupling.  Two embodiments  are  illustrated:  a  working embodiment  in which  cross-coupling  torques  are  produced about  two axes  (Y,Z),  and  a  more  general  embodiment  in which cross-coupling torques are present about all three axes (X,Y,Z).

Abstract: SWITCH MONITORING ARRANGEMENT WITH   REMOTE ADJUSTMENT CAPABILITY             ABSTRACT       An independent transmitter/receiver, or a trans-ponder in a communication system,  receives signals distorted by outside, unwanted conditions such as noise, line capacitance, and so forth.  The status of a switch is checked at periodic times, by pulsing, rather than by continuous current flow, to conserve power.  The invention includes a debounce circuit for monitoring the switch status; the debounce circuit is adjusted by a debounce select signal received from outside the transmit-ter/receiver.   In addition a sensing circuit is coupled between the switch being monitored and the debounce circuit.   The sensing circuit also has its sensing operation adjusted as a function of the debounce select signal.  This allows for accurate monitoring of the switch condition,  notwithstandng noise,  line capacitance and other factors.

Abstract: PATENT     ABSTRACT OF THE DISCLOSURE           A technique is disclosed for preventing a computer program from being used by a computer system other than a designated system.  The values of certain characteristics exhibited by the designated computer system first are stored, and then the values of those same characteristics exhibited by the computer system which is intended to use the computer program are measured and compared to the stored values.  If the compared values are substantially the same, the computer program may be executed.  However, if they are different, the computer system which was intended to use the program is inhibited from executing that program.  The aforementioned characteristics comprise one or more, and preferably at least two, of the following: an identification of the processor included in the computer system, the clock speed of the clock generator included in that system, an identification of the ROM normally provided with the processor, the wait time assigned to the processor for accessing a RAM, the actual rotary speed of a disk drive normally provided with the computer system, the access speed of that disk drive, and the sector interleave value of that disk drive.

Title: Measurement and control of exhaust gas recirculation with an oxygen pumping device
Inventor: LOGOTHETIS ELEFTHERIOS M
IPC: G01M15/00
Filed: 1989-06-14
Granted: 1992-02-04
Abstract: ABSTRACT OF THE DISCLOSURE        An electrochemical device and method measures the percentage of exhaust gas in the intake air/exhaust gas mixture going to the cylinders of an internal combustion engine.  Two electrochemical pump cells and a support structure form a restricted volume in communication through an aperture to an ambient of intake air and exhaust gas mixture.  Constant current is passed through a first pump cell to cause a portion of oxygen molecules inside the restricted volume to be pumped out. A constant voltage across the second pump cell causes substantially all the remaining O2 molecules inside the restricted volume to be pumped out.  Current flowing in the second pump cell is measured, the current being proportional to the percentage o O2 inside the restricted volume and hence proportional to the percentage of O2 in the intake air and exhaust gas mixture, which is a measure of %EGR.

Abstract: OBLIVIOUS MEMORY COMPUTER NETWORKING                      ABSTRACT OF THE DISCLOSURE      Independent heterogeneous computers are interconnected for oblivious,  high speed,  long distance communications. A printed circuit  board  with  onboard  RAM  repeats  all  write  commands through a data transmission media to a remote system.  Each read and  write  cycle  of  the  communicating  computer  is  completed locally  (using  only  local  RAM).   Apart  from repeating write commands to a remote system, the invention is oblivious to the remote system.   Data is transmitted from one machine to another without expensive communication protocols or transmission line latency induced wait states.  A remote computer accesses network data  only  after it has been transmitted and stored in local memory.   Multiple data  transfers  can be  pipelined,  that  is, multiple  datum  may  simultaneously  reside  in  a  high  latency network/long transmission line.   Although the time required to transmit any single datum remains proportional to the signal propagation delay, the time required to transmit multiple data is significantly  reduced.    Geographic  separation,  high  speed transmission  lines,  low speed transmission  lines,  alternative means  for  data  transmission,   fault  tolerance,  one-way communications, multi-way communications, and high security can be supported by a single computer network of heterogeneous machines.
