The present system performs linear transformations on input probabilities and produces outputs which indicate the likelihood of one or more events. The transformation performed is a product of linear transforms such as P. sub. o =[A. sub. j P. sub. j +B. sub. j ]. multidot. [A. sub. k P. sub. k +B. sub. k ] where P. sub. j and P. sub. k are input probabilities, P. sub. o is an output event probability and A. sub. j, B. sub. j, A. sub. k and B. sub. k are transformation constants. The system includes a basic processing unit or computational unit which performs a probabilistic gate operation to convert two input probability signals into one output probability signal where the output probability is equal to the product of linear transformations of the input probabilities. By appropriate selection of transformation constants logical and probabilistic gates performing the functions of AND, NAND, OR, NOR, XOR, NOT, IMPLIES and NOT IMPLIES can be created. The basic unit can include three multipliers and two adders if a discrete component hardwired version is needed for speed or a single multiplier/adder, associated storage and multiplex circuits can be used to accomplish the functions of the hardwired version for economy.

An array of individual and autonomous modules are deployed in a region to be surveilled. Each module, contained in an air dropable bomblet, includes a GPS system for determining the exact location of the deployed module. The module also includes an rf receiver and transmitter, as well as an atomic clock circuit for providing highly precise time and clocking signals, with operation of the module circuitry being governed by a control computer. The computers of the modules are individually programmed such that the modules of the array collectively operate as a distributed phased array antenna system, but without any hardwired interconnection between the modules. In another embodiment a single receiver is utilized and the apparatus operates on the frequency set of the GPS system.

A digital set theoretic system is disclosed that expands the reasoning capability from reasoning with probability measures to reasoning with set theory measures and other Venn diagram type operations using linear transformations and power series transformations, and appropriate hardware and software implementations. This expansion also leads to an increase in precision of the output which can be provided by a hardwired power series expansion. A recursive power series expansion increases this precision while reducing the spatial requirements. The system also enhances flexibility by allowing the constants of the power series expansion to be selectable.

Push-pull flux quantum superconducting digital logic circuits are provided with a circuit branch having a pair of Josephson junctions electrically connected in series with each other. This circuit branch is connected between positive and negative bias voltage supplies which supply a bias current to the Josephson junctions. A dual polarity input voltage signal is applied to a node in the circuit branch and an output signal is extracted from a second node in the circuit branch. Various logic operations can be performed on the input signal by adding additional components and changing the points at which voltage is input to and output from the Josephson junction circuit branch.

A spill condition venting system for a double containment tank includes a control system for controlling, in the event of a spill or an overflow of fluid into the annulus of such double containment tank, the flow of stored fluid into and out of the annulus and for controlling vapor resulting from such spill.
