    摘要： The invention utilizes a sensing body having a non-zero product of inertia to sense acceleration when oscillated about the y'-axis of an x'-y'-z' Cartesian coordinate system. The product of inertia is computed with respect to an x-y-z coordinate system fixed in the sensing body, the z-axis being in the x'-z' plane, the y and y' axes being aligned in the absence of acceleration. The sensing body is pivotally attached to a platform and pivots about an axis parallel to the z-axis. A torquing device applies a torque about the z-axis to the sensing body sufficient to cause the angle between the y-axis and the y'-axis to be zero in the absence of acceleration when the sensing body is being oscillated at a predetermined rate. The accelerometer also includes an orientation sensor which provides a measure of the average angle between the y-axis and the y'-axis. A drive assembly oscillates the platform about the y'-axis. A control circuit receives the output of the orientation sensor and causes the drive assembly to drive the platform at an oscillation rate or at an oscillation amplitude which causes the average orientation angle to be near zero. The invention can also use an assembly of N individually-pivoting sensing bodies to sense acceleration.

    摘要： The invention utilizes a sensing body having a non-zero product of inertia to sense acceleration when spun about the y'-axis of an x'-y'-z' Cartesian coordinate system. The product of inertia is computed with respect to an x-y-z coordinate system fixed in the sensing body, the z-axis being in the x'- z' plane, they and y' axes being aligned in the absence of acceleration. The sensing body is pivotally attached to a platform and pivots about an axis parallel to the z-axis. A torquing device applies a torque about the z-axis to the sensing body sufficient to cause the angle between the y-axis and the y'-axis to be zero in the absence of acceleration when the sensing body is being spun at predetermined rate. The accelerometer also includes an orientation sensor which provides a measure of the angle between the y-axis and the y'-axis. A drive assembly rotates the platform about the y'-axis. A control circuit receives the output of the orientation sensor and causes the drive assembly to drive the platform at a rate which causes the orientation angle to be near zero. A rotation sensor provides a measure of either the angle of rotation of the platform or the angular velocity of the platform. The acceleration is determinable from the angular velocity of the platform and the velocity is determinable from the angle of rotation. The invention can also use an assembly of N individually-pivoting sensing bodies to sense acceleration.

    摘要： Example embodiments of the present invention includes systems and methods for implementing a scalable symmetric multiprocessing (shared memory) computer architecture using a network of homogeneous multi-core servers. The level of processor and memory performance achieved is suitable for running applications that currently require cache coherent shared memory mainframes and supercomputers. The architecture combines new operating system extensions with a high-speed network that supports remote direct memory access to achieve an effective global distributed shared memory. A distributed thread model allows a process running in a head node to fork threads in other (worker) nodes that run in the same global address space. Thread synchronization is supported by a distributed mutex implementation. A transactional memory model allows a multi-threaded program to maintain global memory page consistency across the distributed architecture. A distributed file access implementation supports non-contentious file I/O for threads. These and other functions provide a symmetric multiprocessing programming model consistent with standards such as Portable Operating System Interface for Unix (POSIX).

    摘要： A biopsy cannula and a method are provided for capturing and retrieving a specimen of soft tissue for subsequent diagnostic evaluation. The biopsy cannula defines a passageway of non-circular cross-section. The cannula is inserted into target tissue and rotated about the longitudinal axis of the cannula. The non-circular cross-sectional shape of the passageway in the cannula helps the cannula grippingly engage the tissue and cause the tissue to rotate with the cannula. Regions of the tissue adjacent the distal end of the cannula will be subjected to torque and will be severed from tissue outside the cannula. The cannula may then be withdrawn with the severed core of target tissue therein. The exterior of the cannula may be generally rounded or cylindrical in shape.
