Title: High resolution 3d ultrasound imaging system deploying a multi-dimensional array of sensors and method for multi-dimensional beamforming sensor signals
Inventor: DHANANTWARI AMAR C
IPC: G10K11/34
Filed: 1999-11-24
Abstract: An adaptive multidimensional beamformer having near-instantaneous convergence for ultrasound imaging systems deploying multidimensional sensor arrays is disclosed. In a first step, the multidimensional beamformer is decomposed into sub-apertures. Each sub-aperture is then again decomposed into two coherent subsets of circular and/or line array beamformers in different coordinate directions of the multidimensional array. Implementation of the multidimensional beamformer according to the present invention provides the basis for a 3D ultrasound imaging system according to the present invention comprising a compact multidimensional sensor array and a compact processing unit that is field deployable and generates high resolution three--dimensional images in real time. It is also possible to capture four- dimensional images, the fourth dimension being time and the resulting images forming a video image of a volume of a moving organ.

Title: Method for providing bandwidth and delay guarantees in a crossbar switch with speedup
Inventor: SIMCOE ROBERT J
IPC: H04L49/111
Filed: 1999-01-12
Abstract: An arbitration scheme for providing deterministic bandwidth and delay guarantees in an input-buffered crossbar switch with speedup S is presented.  Within the framework of a crossbar architecture having a plurality of input channels and output channels, the arbitration scheme determines the sequence of fixed-size packet (or cell) transmission between the input channels and output channels satisfying the constraint that only one cell can leave an input channel and enter an output channel per phase in such a way that the arbitration delay is bounded for each cell awaiting transmission at the input channel. If the fixed-sized packets result from fragmentation of variable size packets, the scheduling and arbitration scheme determines deterministic delay guarantees to the initial variable size packets (re-assembled at the output channel) as well.
