Title: Bus transmitter having controlled trapezoidal slew rate
Inventor: GRONDALSKI DAVID S
IPC: H03K4/94
Filed: 1988-05-06
Granted: 1991-11-26
Abstract: ABSTRACT OF THE DISCLOSURE      A transmitter circuit for transmitting a digital data signal over a bus in a digital data processing system includes a MOSFET bus driver transistor having a gate to drain capacitance CGD which substantially dominates other capacitances at the gate terminal.  The bus driver transistor is driven by a buffer circuit having pull-up and pull-down transistors current through which is controlled by current sources.  The gate terminal of the driver transistor is connected to, and controlled by, the node between the pull-up and pull-down transistors.  The drain terminal of the driver transistor is connected to, and controls, a bus line.  To assert a signal on the bus line, the pull-up transistor is turned on to drive current into the node at a rate governed by the current source, which increases the voltage level of the node.  When the voltage level of the node reaches the driver transistor's threshold level, the driver transistor begins to turn on, allowing the voltage level of the bus line to drop.  Contemporaneously, current flows into the node from the bus line through the driver transistor's high gate to drain capacitance, thereby limiting the voltage level of the node, and thus the current flow through the driver transistor.  Thus, current flows through the driver transistor from the bus line in a manner controlled, in part, by the voltage level on the bus line.          In negating a signal on the bus line, the operations are similar, with current flowing out of the node through the pull-down transistor and the driver transistor's gate to drain capacitance.

Granted: 1993-08-24
Abstract: ABSTRACT OF THE DISCLOSURE    A three-axis gravity gradiometer including three component gravity gradiometers arranged in mutually orthogonal directions, wherein each component gradiometer includes a pair of accelerometers each defining a sensitive axis.  Each accelerometer includes a generally cylindrical proof mass made of a superconducting material.  Each proof mass includes annular upper and lower hollowed out portions longitudinally surrounded by a generally cylindrical exterior wall.  Common mode and differential mode sensing coils are arranged adjacent a bottom-side surface of a portion of the proof mass in one hollowed out annular portion and a levitation coil is arranged adjacent a bottom-side surface of the proof mass in the other hollowed out annular portion.  The common mode, differential mode and levitation coils are connected in respective first, second and third superconducting circuits.  The first circuit produces common mode signals indicative of forces acting on both accelerometers in the same direction.  The second circuit produces differential mode signals indicative of forces acting on the accelerometers in different directions.  The third circuit produces a force on each proof mass by which the proof masses are levitated.  In addition, a superconducting negative spring coil is wound on the periphery of the coil form.  A persistent current is stored in each negative spring loop to cancel the rigidity of the mechanical spring.  Also provided are superconducting circuits for common mode and differential mode force rebalance, residual sensitive axis angular misalignment compensation, and differential proof mass levitation at start-up.  Either piezoelectric crystal transducers or persistent current loops are used to obtain residual sensitive axis linear misalignment compensation.     80/rac/sjh
