Title: Universal/upgrading pulse oximeter
Inventor: VADEN VAL E
IPC: A61B5/00
Filed: 2000-01-25
Abstract: A universal/upgrading pulse oximeter (UPO) (210) comprises a portable unit (610) and a docking station (660,910) together providing three-instruments-in-one functionality for measuring oxygen saturation and related physiological parameters. The portable unit functions as a handheld pulse oximeter. The combination of the docked portable and the docking station functions as a stand-alone, high-performance pulse oximeter. The portable-docking station combination is also connectable to, and universally compatible with, pulse oximeters from various manufacturers through use of a waveform generator (320, 930). The UPO provides a universal sensor to pulse oximeter interface and a pulse oximeter measurement capability that upgrades the performance of conventional instruments by increasing low perfusion performance and motion artefact immunity, for example. Universal compatibility combined with portability allows the UPO to be transported along with patients transferred between an ambulance and a hospital ER, or between various hospital sites, providing continuous patient monitoring in addition to plug-compatibility and functional upgrading for multiparameter patient monitoring systems.  The image on the portable display (264, 740) is rotatable, either manually when undocked or as a function of orientation (950). In one embodiment, the docking station (660) has a web server and a network interface (1410) that allows UPO data to be downloaded and viewed as web pages over a local area network (1420) or the Internet.

Abstract: A ramjet engine (3, 4, 5), flying at Mach 3 has 64% efficiency, and at Mach 4 has 76% efficiency. Ramjet engines are currently only used for supersonic flight and have not been used as stationary engines with mechanical output. The present invention, in addition to subsonic flight, can be operated as a stationary engine, and can expand the use of the ramjet engine for mechanical output in vehicles, power plants, and in generator sets for large buildings, homes, and industry. The present invention provides the means to use ramjet engines as stationary engines by building nearly adiabatic compressors (1, 2, 12, 13, 14, 15) and expanders (6, 7, 8, 9, 10, 11) capable of (de-)compression ratios up to about 92: 1 to supply the high energy gas/air required by ramjet engines, and shows how to replace de Laval nozzles with sonic converters (49, 50, 51) that convert supersonic to subsonic flow and sonic convertors (45, 46, 47) that convert subsonic to supersonic flow without having choke areas.

Abstract: A pulping apparatus includes a hollow mixing cylinder selected to retain a volume of pulping fluid and cellulose fibres therein. The mixing cylinder is journaled for rotation about a central axis oriented at approximately + 20° from horizontal.  In a preferred construction, the mixing cylinder is divided internally into at least two discrete mixing chambers configured to facilitate outward flow of defibred pulp from an infeed end of the cylinder to and outwardly from the outlet end. The mixing chamber adjacent the inlet end is delineated by an end cover which closes the inlet end, and by a first divider positioned across the cylinder interior. The next adjacent mixing chamber is delineated longitudinally by the distal-most divider of the end mixing chamber, and by a second further downstream divider spaced longitudinally therefrom. The dividers include at least one through-opening therethrough. The through-openings regulate the flow of pulp and fluid along the mixing cylinder, while maintaining minimum cellulose/fluid levels in each mixing chamber. The through-openings may be positioned in alignment with, or in an asymmetrical arrangement relative to the cylinder axis so as to move eccentrically relative thereto as the mixing cylinder rotates.
