Abstract: The invention provides an acoustic transducer for transmitting acoustic wave energy in response to an electrical signal and for converting the received acoustic wave energy into an electric signal. The transducer includes an array of piezoelectric elements (52), a backing layer (30) attached at a rearward face of the piezoelectric elements, a circuit element (54) spaced apart from the piezoelectric elements (52) by the backing layer (30), and at least one electrical conductor (24) for each of the piezoelectric elements (52) to connect the elements to the circuit element (54). The backing layer (30) comprises a plurality of layers (10) of acoustic attenuating material integrally formed into a laminate structure. The electrical conductors (24) extend along a surface of each of the layers (10) and have a predetermined pitch. Each of the layers (10) has a thickness substantially equivalent to the pitch of the electrical conductors (24). Individual piezoelectric elements (52) are formed on the upper surface (32) of the laminate structure (30), and conductive pads (46) are formed on the lower surface (34) of the laminate structure. The electrical conductors (24) provide electrical connection through the backing layer (30) between the piezoelectric elements (52) and the associated conductive pads (46).

Abstract: An antenna system comprises a main antenna (1) for use in transmission and reception and a pair of sub-antennas (2) for use only in reception. The antenna beam of the antenna system is scanned in the direction of the beam width to be compressed. Both received signals of the main antenna (1) and the sub-antennas (2) are fed to a signal processing circuit (4). The signal processing circuit (4) converts these received signals to power signals and then performs signal processing on them. In this signal processing, the power signal received by the main antenna is output as a final output signal only if both double differential coefficients of the received signals received by the main antenna and the sub-antennas are equal to or less than corresponding predefined positive real number values, and if the phase difference between the power signal received by the main antenna and the power signal received by the sub-antennas is equal to or less than 90°, thereby producing the output signal representing faithfully the distribution of scattering objects without distortion.

Abstract: The present invention provides a method and display system for reducing the visual impact of defects present in an image display. The display includes an array of pixels  200 , each non-defective pixel being selectively operable in response to input data by addressing facilities between an "on" state, whereat light is directed onto a viewing surface, and an "off" state, whereat light is not directed onto the viewing surface. A defect is the result of a defective pixel  202  which does not respond to the input data presented by the addressing facilities, typically by continuously remaining in its "on" or "off" state. Each defective pixel  202  is immediately surrounded by a first ring of compensation pixels  204  adjacent to the central defective pixel  202 . The compensation pixels  204  are immediately surrounded by a second ring of reference pixels  206  spaced from the central defective pixel  202 . The addressing circuit-determined value of at least one compensation pixel  204  in the first ring surrounding the defective pixel  202  is changed to a corrective value, in order to reduce the visual impact of the defect.

Abstract: A valved adapter for a medical access device includes a body with a longitudinal axis. The body has a proximal first end, a distal second end and a passageway therethrough which has an inside surface. The passageway has a chamber defined by a proximal shoulder and a segmented distal shoulder both projecting inwardly from the surface of the passageway. The chamber is located intermediate the first end and second end of the body. The adapter includes a valve contained within the chamber for selectively obstructing and allowing fluid flow through the passageway. The valve includes an elongate resilient member with an axis substantially coaxial to the longitudinal axis of the body having a proximal end and a distal end. The elongate resilient member is axially compressed between the distal shoulder and the proximal shoulder, the compression biasing the valve to a normally closed position. The proximal end of the resilient member forms a substantially fluid tight seal with the proximal shoulder which obstructs fluid flow through the passageway. The adapter further includes a pusher for selectively further axially compressing the resilient member so that the proximal end of the adapter no longer forms a fluid tight seal with the proximal shoulder thereby allowing fluid flow through the passageway. The adapter includes fittings for attaching the adapter to a medical access device and for attaching fluid delivery devices to the adapter.

Abstract: A ferroelectric memory includes a circuit for temporarily controlling a parasitic capacitance of a pair of data signal lines to an optimum value, when data is read out from a memory cell, for the purpose of minimizing a variation of the voltage on the pair of data signal lines caused by factor other than the current caused due to the polarization of the ferroelectric capacitor. Thus, a voltage not smaller than the coercive voltage can be applied between the opposing electrodes of the ferroelectric capacitor, with the result that a sufficient read-out signal voltage can be obtained.

Abstract: In a technique of monitoring whether a physical system is normal or abnormal by continuously comparing a phenomenon taking place in the system and a phenomenon taking place in a model and also in a technique of control adopting evaluation functions using an error quantity in the model, the phenomena in both the physical system and model can be optimized. An equivalent electric circuit to the physical system is produced, and an input is provided to both of the system and the circuit. In this state, the output of the physical system and the reference value of the equivalent electric circuit are compared. The use of the equivalent electric circuit permits solving the problem inherent in the prior art that the time necessary for analog-to-digital conversion and numerical calculations is longer than the time of the actual phenomenon and disables real time simulation.

Abstract: A method for detecting islanding operation of a rotating-machine type dispersed generator. The dispersed generator is interconnected with a main electric source through a circuit breaker to constitute an electric power system. The estimating method is implemented as follows: (a) changing electric power of the electric power system; (b) detecting frequency component of the electric power; and (c) deciding that an islanding operation of the dispersed generator is executed if the change of the frequency component becomes greater than a predetermined value. With this method, it becomes possible to detect the islanding operation of the dispersed generator even if the power flow at the interconnecting circuit breaker is generally zero.
