Title: Multi-hop packet radio networks
Inventor: VAN LOCHEM GERHARD WILLEM
IPC: H04L12/56
Filed: 1995-12-19
Granted: 2005-07-05
Abstract: An adaptative communication system utilizes opportunistic peak-mode transmissions to transmit data between originating and destination stations, via one or more intermediate stations. Each station monitors the activity of other stations in the network, storing connectivity information for use in subsequent transmissions. Each station also sends out probe signals from time to time, to establish which other stations are in range. Messages are then sent across the network from station to station, with confirmation data being transmitted back to the originating station, until the destination station is reached. Old messages, which would otherwise clog the network, are timed out and deleted. A communication network and transceiver apparatus for use in the network are also disclosed.

Abstract: Systems and methods for separating mono nuclear cells from whole blood rotate a separation compartment (38) about a rotational axis. Whole blood is introduced from an inlet region (74) into a first region (76) of the chamber during its rotation to separte the whole blood into a plasma constituent, red blood cells and interphase between the red blood cells and the plasma constituent. The interface contains mono nuclear cells. While conveying whole blood into the first region, the plasma constituent is collected in the first region, while collecting the red blood cells in a second region of the chamber spaced away from the inlet region. Red blood cells are than conveyed into the second region (78) in a back flow direction toward the inlet region. While conveying red blood cells into the second region, the mono nuclear cells are collected in the first region.

Title: Multivariate statistical model-based system for monitoring the operation of a continuous caster and detecting the onset of impending breakouts
Inventor: VACULIK VIT
IPC: G01K1/14
Filed: 1999-07-20
Granted: 2008-07-08
Abstract: A method of monitoring the operation of a continuous caster in which a multivariate statistical model is developed using off-line measurements of process parameters representing normal operation of the continuous caster.  On-line process parameters are measured in real time to determine if the caster operation is normal by calculating test statistics on vectors calculated using the multivariate statistical model with input from the on-line process parameters.    The method may advantageously be used to predict breakouts in a continuous caster and allows an operator to take corrective action to avoid such breakouts.  Corrective action may also be taken automatically.
