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.

A radio frequency navigation receiver has analog and digital sections. In the analog section, a CRPA antenna module receives global navigation signals and provides two steerable nulls for jammer suppression. An analog RF module has an amplifier and a YIG filter for amplifying and filtering an antenna output signal with jammer suppression. An analog receiver receives and downconverts an RF output signal from the RF system with additional jammer suppression. The analog receiver provides broadband signal filtering with at least 30 dB rejection and narrow band signal filtering with at least 45 dB rejection. In the digital section, a digital receiver module receives and converts an analog receiver output signal to generate a digital output signal for navigation control. A configuration manager processor responds to detected jammer signals to configure the receiver modules accordingly.

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.

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.

Superconducting timed gate array cells for use in single-rail logic circuits are provided by adding inputs to modified variable threshold logic (MVTL) timed inverter circuits. Data signals which are inphase with a first phase of a power source are coupled to gate array cells in which Josephson junction bias current is provided by a second phase of the power source. NOR, NAND, 2NOR-OR and 2NAND-AND circuits are disclosed for use as building blocks in the production of specialized digital logic circuits.

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.
