Title: Phase modulated pulse logic for gallium arsenide
IPC: H03K19/096
Filed: 1985-08-27
Abstract: A logic system preferably for gallium arsenide integrated circuits uses dynamic pulsed logic gates which switch on each clock pulse, with the logical state of an output or data line being indicated by the phase of the pulsed output, which may be shifted or modulated with respect to a reference. An individual logic gate (1) has a first signal generator having a capacitor (30) which is either charged up or discharged during a set-up phase of a clock cycle, depending upon applied input logic signals. During a second, transmit phase of the clock signal, the signal developed on the capacitor is output from the gate. A second signal generator (112 - 131) is an inverting slave of the first, and outputs the inverse logic state during the succeeding set-up phase of the first generator. 
<??>With each gate switching on every clock period, all switching noise appearing in the ground or power supplies is at or above the clock frequency and can simply be filtered out with small chip capacitors, providing improvements in noise immunity. 
<??>The logic is preferably implemented in gallium arsenide metal oxide semiconductor technology, with the capacitors formed from reverse-biased Schottky diodes and all FET switches capacitively coupled and self biased.

IPC: G05B13/00
Filed: 1986-03-13
Abstract: A digital motor control system includes a feedback element (32) attached 
to a motor (34) which periodically obtains information descriptive 
of actual motor position and velocity, compares this information 
with desired values for position and velocity to determine a system 
vector which defines both position error and velocity error as a 
single point on a cartesian coordinate error plane, compares this 
vector to a decision-making criterion represented as a continuous 
function on the error plane, and as a result of the comparison causes 
a voltage pulse of appropriate duration and polarity to be applied 
to the motor (34). A pulse of a first preselected width is applied 
to accelerate the motor (34) if the system vector is located on one 
side of the function, or a pulse of a difference width and/or polarity 
is applied to cause the motor to decelerate if the system vector 
is on the other side of the return function.

the incorporation of documents of all types by 
integrating images into the system. A 
minicomputer-based system includes applications 
such as word processing, data base, and mail, each 
of which can access image documents. Bulk storage
