Abstract

A bilateral circuit is operable for transmitting signals in two directions without generation of ringing due to feedback caused by the insertion of the circuit. The circuit may include gain for each of the signals to provide a bidirectional amplifier. The signals are passed through two separate paths, with a unidirectional amplifier in each path. A controlled sampling device is provided in each path for sampling the two signals. Any feedback loop between the two signals is disrupted by providing a phase displacement between the control signals for the two sampling devices.

Bidirectional amplifier

Patent Wright, J.T.

A bidirectional amplifier is described for passing first signals from a first source circuit to a destination circuit and second signals from a second source circuit to the first source circuit. The amplifier consists of: first switchable signal path means, connected between the first source circuit and the destination circuit, for passing either only the first signals which closed or no signal while open; second switchable signal path means, connected between the second source circuit and the first source circuit, for passing either only the second signals while closed or no signal while open; and switching signal generating means, connectedmore »« less

Superconducting analog-to-digital converter with bidirectional counter

Patent Phillips, R.R.; Sandell, R.D.; Silver, A.H.

A superconducting analog-to-digital converter is described comprising: a double-junction superconducting quantum interference device (SQUID) having first and second Josephson junctions and a center-tapped load inductance; means for applying a constant gate current to the center of the load inductance; means for applying a bidirectionally varying analog signal current to the load inductance. Positive incremental changes in the analog signal current result in the generation of voltage pulses across the first junction, and negative incremental changes in the analog current signal result in the generation of voltage pulses of the same polarity across the section junction; and means for counting themore »« less
Bidirectional ground coupling means for inclined seismic source

Patent Airhart, T.P.

Apparatus for generating combined compressional and shear wave signals in the earth which employs a seismic source, such as a cylindrical gas exploder, having a free-moving wedge shaped base which tapers symmetrically downwardly to a thin blade. When the exploder is fired at an angle inclined to the vertical, a force is generated along its longitudinal axis which drives the base downwardly in the same direction so as to propagate seismic signals having a compressional component and a shear component. The blade is disposed transversely to the direction of the horizontal component of this applied force. The penetration achieved bymore »« less
Lambda network having 2{sup m{minus}1} nodes in each of m stages with each node coupled to four other nodes for bidirectional routing of data packets between nodes

Patent Napolitano, L.M. Jr.

The Lambda network is a single stage, packet-switched interprocessor communication network for a distributed memory, parallel processor computer. Its design arises from the desired network characteristics of minimizing mean and maximum packet transfer time, local routing, expandability, deadlock avoidance, and fault tolerance. The network is based on fixed degree nodes and has mean and maximum packet transfer distances where n is the number of processors. The routing method is detailed, as are methods for expandability, deadlock avoidance, and fault tolerance. 14 figs.
