Patent CA-2460762-A1 (CA)
Inventor: ZHANG FAN
IPC: F42B3/00
Filed: 2004-03-12
Abstract: A method and apparatus for high pressure compression of materials and for detonation of the compressed material by cylindrical implosion followed by an axial detonation to a detonation velocity several times that of TNT and a detonation pressure in excess of ten times that of TNT. The device provides a conical metal flyer shell within which is disposed a cylindrical anvil surrounded by explosive. The anvil retains a sample material to be compressed and detonated. A first detonation of explosive by impact of the flyer shell generates a reverberating oblique shock wave system for sample compression. Axial detonation of the compressed sample through any length of a sample is achieved following the principal of matching the axial velocity and compression time of the oblique shock wave system to the detonation rate and induction delay time of the compressed sample. The method and apparatus are also applicable to enhancing the effect of anti-armour and anti-hard-target munitions. The apparatus is also applicable to inert sample compression to the megabar range without using the axial detonation.

Abstract: A test probe alignment apparatus includes a rotatable  stage that is decoupled from a workpiece positioning stage so that the workpiece positioning stage can move a workpiece in an XY plane without moving the  stage, thereby inhibiting vibration in and inertia of the workpiece positioning stage, and improving the speed and accuracy of workpiece movements. The  stage is driven for rotation about an axis substantially perpendicular to the X-Y plane. The rotatable stage supports a carriage adapted for holding a probe card. The carriage rotates in concert with the  stage to thereby align the probe card relative to the workpiece. A Z-stage is operatively engaged with the carriage for moving the carriage along the axis of rotation relative to the workpiece. A computer processor performs coordinate transformations on preprogrammed movement vectors, to adjust for angular misalignment of the workpiece as measured by a position sensor.

Title: Integrated wireless distribution and mesh backhaul networks
Inventor: HERSCOVICH BERNARD
IPC: H04L12/56
Filed: 2003-06-27
Abstract: Networks, devices and methods related to wireless networking. A wireless network using nodes that perform both distribution and backhaul functions is provided. These nodes constitute the key elements of a wireless network that would be deployed and controlled by a wireless network operator. Each node contains a distribution wireless module which is wirelessly coupled to the wireless end user device using a point to multipoint scheme. Also integrated into each node is at least one backhaul wireless module with a directional wireless antenna. Each backhaul wireless module communicates by way of a poi nt to point wireless link with the backhaul module of one other node. The nodes in the wireless network are interconnected to form a mesh backhaul network. Because of the nature of a mesh network, data traffic can be routed around obstacles that may prevent line of site links. Furthermore, the mesh network allows dynamic routing of data traffic to avoid congestion points or downed links in the network.

Inventor: SZYPERSKI THOMAS A
IPC: G01R33/46
Filed: 2003-07-10
Abstract: The present invention presents a new approach to rapidly obtaining precise high-dimensional NMR spectral information, named "GFT NMR spectroscopy", whi ch is based on the phase sensitive joint sampling of the indirect dimensions spanning a subspace of a conventional NMR experiment. The phasesensitive joi nt sampling of several indirect dimensions of a high-dimensional NMR experiment leads to largely reduced minimum measurement times when compared to FT NMR. This allows one to avoid the "sampling limited" data collection regime. Concomitantly, the analysis of the resulting checmical shift multiplets, whi ch are edited by the G-matrix transformation, yields increased precision for th e measurement of the chemical shifts. Additionally, methods of conducting specific GFT NMR experiments as well as methods of conducting a combination of GFT NMR experiments for rapidly obtaining precise chemical shift assignment and determining the structure of proteins or other molecules are disclosed.< /SDOAB>
