Assignee:

Boston Scientific Corporation - Natick MA

International Classification:

A61B 500

US Classification:

600585

Abstract:

Implements, particularly medical instruments, formed at least in part of elongated polymer members, exhibit high torque fidelity after processing with tension, heat, and twisting. The processing orients the polymer in generally helical paths so that torque imposed at the proximal end can be transmitted to the distal end without substantial whipping, even if the implement follows a long and tortuous pathway. Applications include medical guidewires, catheters, and driveshafts.

US Classification:

367153

Abstract:

A hydrophone assembly for deployment on the bottom of a body of water is vided wherein a plurality of hydrophones are mounted in a spaced apart relationship about the circumference of a housing which is designed to hold signal processing electronics. Each hydrophone is constructed to detect a range of frequencies within a defined receive angle that extends outward from the circumference of the housing. A resonance absorbing material is interposed between the housing and the hydrophones to isolate each hydrophone from mechanical resonance. Tilt switches are connected to each hydrophone for automatically and independently selecting hydrophones to participate in the output of the hydrophone assembly based on the orientation of the hydrophones. Selected adjacent hydrophones define a continuous receive angle formed by combining the receive angle associated with each adjacent hydrophone. The continuous receive angle faces upward from the bottom of the water to include an angular portion of the surface.

Abstract:

Barium titanate based dielectric compositions having the general formula Ba. sub. (1-x-x'-x") Pb. sub. x Ca. sub. x' Sr. sub. x" Ti. sub. (1-y-y'-y") Sn. sub. y Zr. sub. y' Hf. sub. y" O. sub. 3, wherein x, x', x" and y, y', y" represent mole fractions of the divalent and tetravalent cations and x and x' have independent value greater than 0. 01 and less than 0. 3 and x", y, y' and y" have independent values greater than zero and less than 0. 3, such that the sum (x+x'+x") is greater than 0. 01 and less than 0. 4 and the sum (y+y'+y") does not exceed 0. 4. Regardless of the specific composition selected, the products of the invention have a mean primary particle size in the range of 0. 05 to 0. 4 microns with a very narrow particle size distribution. The products are dispersible so that the mean particle size determined by image anaylsis and by sedimentation are comparable.

International Classification:

G06F 1120

US Classification:

371 68

Abstract:

A fualt-tolerant computer system provides information transfers between the units of a computing module, including a processor unit and a memory unit and one or more peripheral control units, on a bus structure common to all the units. Information-handling parts of the system, both in the bus structure and in each unit, can have a duplicate partner. Error detectors check the operation of the bus structure and of each system unit to provide information transfers only on fault-free bus conductors and between fault-free units. The computer system can operate in this manner essentially without interruption in the event of faults by using only fault-free conductors and functional units. Arbitration circuits of unusual speed and simplicity provide units of the computing module with access to the common bus structure according to the priority of each unit. The units of a module check incoming and outgoing signals for errors, signal other module units of a detected error, and disable the unit from sending potentially erroneous information onto the bus structure.

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

G06F 102

US Classification:

377 42

Abstract:

A digital calibration circuit provides 1/3 octave center frequencies substially in the range of 50 Hz-12. 5 kHz (25 tones) simultaneously at the output at repeatable levels. The system converts digital data to an analog representation for use in calibrating hydrophones. The calibration circuit is comprised of a clock section, a counting section, a clearing section, a data storage/transfer section, and a signal conditioning section. The information that is provided to the output in analog form is stored in digital form in an EPROM within the data storage/transfer section.

International Classification:

H04J 300

US Classification:

359135

Abstract:

A multiplexing node is associated with each analog sensor of a line array. ach multiplexing node has an amplifier/filter section coupled to its associated analog sensor for amplifying and shaping a signal generated by the sensor. An A/D converter then samples the signal. A receiver is coupled to a previous one of the multiplexing nodes for receiving scrambled data and clock information in serial fashion from the previous node. A descrambler is coupled to the receiver to separate the data from the clock. A processor is coupled to the A/D converter and the descrambler. The processor time division multiplexes the data and clock from the previous node with the sampled signal from the A/D converter. The processor scrambles the so multiplexed data, clock and sampled signal. A transmitter is coupled to the processor to transmit the scrambled data, clock and sampled signal in serial fashion over a single data line.

International Classification:

C04B 3549

US Classification:

501138

Abstract:

The present invention relates to a variety of dispersible doped multi-component BaTiO. sub. 3 based powder compositions. The primary particles of each of the products are substantially spherical, have sizes in the range of 0. 05 to 0. 4 microns and have narrow size distributions. Further, the compositions of the primary particles, forming each powder, are comparable. The amount of dopant oxide or oxides contained in the powder composition ranges from between greater than 1 to 10 mole percent. Regardless of the dopant or dopants utilzied, all the powder compositions of the present invention are identified by the same unique morphological characteristics.
