Title: Variable speed control of multiple motors
Inventor: HOLDEN STEVE
IPC: F04C28/02
Filed: 2003-11-20
Abstract: A system for variable speed control of a plurality of motors under variable load demand is provided. The system includes a constant power source and a plurality of motors having electrical circuits with switches to connect with the constant power source. The system further includes a variable speed drive for driving each of the plurality of motors at variable speed, wherein each of the plurality of motors includes a switch to connect with the variable speed drive. Each of the plurality of motors is selectively electrically connected with the variable speed drive and the constant power source via the switches, for driving the each of the plurality of motors at one of variable and constant speed in response to load demands. To prevent short cycling of the motors under situations of increasing system demand, the control algorithm for the electrical switches provides hysteresis by overspeeding one of the motors before switching from variable speed mode to constant speed mode. Similarly, hysteresis is included in the control algorithm to prevent short cycling of the motors under situations of decreasing system demand.

Title: Method for non-invasively determining the relative levels of two substances present in a biological system
Inventor: GUY RICHARD HENRY
IPC: A61N1/30
Filed: 2002-06-17
Abstract: The method for non-invasively determining the relative levels of two substances present in a biological system includes the steps of extracting by reverse iontophoresis charged and uncharged substances from said biological system, and collecting said substances, analysing the collected amount of a first extracted substance and a second extracted substance and determining the extraction ratio of the first substance to the second substance to determine their relative levels in the biological system. When the first and second substances are both analytes susceptible to changes in their concentration in the biological system, this method provides information about the relative concentrations of the two substances in the biological system. When the first substance is an analyte susceptible to changes in its concentration in the biological system and the second substance has a substantially constant concentration in the biological system, the second subtance acts as an internal standard and the extraction ratio becomes a direct measurement of the physiological level of the first substance in the biological system. A  iontophoretic sampling device for monitoring the relative levels of two substances present in a biological system is also disclosed.

Title: Fluid thrust assembly with self-aligning thrust bearings
Inventor: LASKEY KEITH
IPC: B63H23/32
Filed: 2004-03-09
Abstract: A thrust bearing assembly is described that includes a self-aligning thrust bearing used in fluid thrust assemblies where the thrust may become unevenly distributed, e.g. in a water jet propulsion unit. The thrust bearing is designed to be lubricated by water and to be self-aligning against uneven thrust forces applied to it. The self-alignment is achieved by the design of the bearing, which is in the form of an annular multi-layer plate. The bearing plate comprises a metallic central core layer, an interface layer of marine bearing material on one side of the core and a flexible backing layer on the other side of the core. The backing layer supports the thrust flange against a support face and is formed of a high resilience polymer material capable of being deformed under thrust action sufficiently to align the thrust bearing to correct for uneven thrust.
