Abstract: PROBLEM TO BE SOLVED: To accurately track a probe or the like inside a three-dimensional continuous body by inserting a strong rare earth magnet arranged at the tip of the probe or a catheter into a volume or a body and detecting the position and direction of the probe or the like by a magnetic field sensor installed near it. SOLUTION: A small strong magnetic dipole 2 and an ultrasonic imaging device 10 are attached to the tip of the thin and long probe or catheter 3 provided with an optional diameter, a flexible shaft 9 and a motor are attached to the other end and the catheter 3 is inserted into the body. For the magnetic field measurement of the catheter, a magnetic sensor 4 (triaxial magnetometer) 4 is used and a platform for supporting the sensor 4 is installed near the body. The catheter 3 inserted into the body is rotated for ultrasonic determination and localizes a distal end of a rotary magnet. The tracking of the rotary magnet instantaneously provides the accurate information on localization of three- dimensional images of the catheter 3.

Abstract: A neural network utilizing the threshold characteristics of a semiconductor device as the various memory elements of the network. Each memory element comprises a complementary pair of MOSFETs in which the threshold voltage is adjusted as a function of the input voltage to the element. The network is able to learn by example using a local learning algorithm. The network includes a series of output amplifiers in which the output is provided by the sum of the outputs of a series of learning elements coupled to the amplifier. The output of each learning element is the difference between the input signal to each learning element and an individual learning threshold at each input. The learning is accomplished by charge trapping in the insulator of each individual input MOSFET pair. The thresholds of each transistor automatically adjust to both the input and output voltages to learn the desired state. After input patterns have been learned by the network, the learning function is set to zero so that the thresholds remain constant and the network will come to an equilibrium state under the influence of a test input pattern thereby providing, as an output, the learned pattern most closely resembling the test input pattern.

Abstract: A superconducting device operable at temperatures in excess of 30oK and a method for making the device are described. A representative device is an essentially coplanar SQUID device (10, 56A, 56B, 58A, 58B) formed in a single layer (12) of high-Tc superconducting material, the SQUID device (10, 56A, 56B, 58A, 58B) being operable at temperatures in excess of 60 K. High energy beams (34), for example ion beams, are used to convert selected portions (30) of the high-Tc superconductor layer (12) to nonsuperconducting properties so that the material now has both, superconducting regions (20A, 20B) and nonsuperconducting regions (30). In this manner a superconducting loop (16A, 16B, 20A, 20B) having superconducting weak links (16A, 16B) can be formed to comprise the SQUID device.
