Title: Hemodialysis monitoring system for hemodialysis machines
Inventor: KESHAVIAH PRAKASH
IPC: A61M1/36
Filed: 1993-10-12
Abstract: An improved on-line real time hemodialysis monitoring system for hemodialysis treatment. The hemodialysis monitoring system quantitates the rate arid amount of a constituent, such as urea, removedduring the hemodialysis treatment by measuring the constituent concentrations as a fonction of time in the spent dialysate effluent from a hemodialysis machine. A quantity of the spent dialysate effluent is removed from the dialysate effluent waste line periodically for testing. A urea concentration time profile can be analyzed to determine the urea removal, KT/V, URR, SRI and normalized protein catabolic rate (nPCR) indices. The hemodialysis monitoring system preferably can obtain a dialysate sample equilibrated with the blood prior to the start of a hemodialysis treatment. The hemodialysis monitoring system includes a two pool analysis for taking into account the constituent concentration differences in the extracellular and intracellular spaces in the hemodialysis patient during the hemodialysis treatment.

Title: Modem Including an Equalizer for Amplitude Jitter
Inventor: RUSHING MICKEY C
IPC: H04B3/00
Filed: 1993-01-04
Abstract: A modem (100) includes an equalizer for equalizing a received signal (10) for amplitude jitter distortion. The received signal includes modulated symbols based on a predetermined constellation of points, each point representing a symbol. The modem first extracts a modulated symbol to provide an extracted symbol, R(k), which includes amplitude jitter distortion. The modem then identifies a signal point Pn(k) of the predetermined constellation corresponding to the extracted symbol. Further, the modem determines an error signal (76) based on the amplitude jitter distortion, and then uses the error signal to compensate subsequent extracted symbols for the amplitude jitter distortion.

Abstract: This high-voltage installation has a metallic enclosure (1) which is filled with insulating gas and surrounds voltage-carrying active parts.   In addition, it has at least one at least partial protective coating (7,  9,  10)  either  on  the  internal  surface  of  the enclosure  (1)  or  on  the  external  surface  over  the active  parts,  or  at  least  one  at  least  partial protective coating  (7,  9,  10)  both on the  internal surface  of  the  enclosure  (1)  and  on  the  external surface of the active parts.        It  is  intended  to  provide  a  high-voltage installation in which free electrons are also reliably removed from the insulating gaps and in which partial discharges generated by free particles are reduced to noncritical values of intensity.   This is achieved in that the at least one protective coating (7, 9, 10) is doped with at least one fullerene which absorbs free electrons.  Protective coatings which have a surface of vapor-deposited   fullerene   are   also   particularly suitable.

Each of the first and second sections (28, 30) are arranged to receive a respective one of the cables (22A, 22B). The jacket clamps (42, 48) engage respective ones of the jackets (26A, 26B) to hold the cables in place. The first section (28) has a fiber retaining, conical member (32) located therein. That member (32) is formed of a substantially hard, yet somewhat compressible material, and includes a fiber-receiving bore (34) extending therethrough.  The internal diameter of the bore is very slightly larger than the external diameter of the fibers (24). The first and second sections (28, 30) are arranged to be releasably secured together to bring the bare free ends (24A, 24B) of the fibers (24) into abutment within the bore (34) to establish a light transmissive joint between them. The second section (30) comprises a compression member having a tapered cavity (36) for engaging and radially compressing the fiber retaining conical member (32), so that the internal diameter of its bore (34) is reduced slightly to axially align the free ends (24A, 24B) of the fibers (24) and to frictionally hold them in place.

IPC: G09G3/28
Filed: 1995-03-13
Abstract: In a monochrome display device, it is known to be important to maintain a constant optical centre of illumination with increasing levels of illumination. Therefore, any pixel arrangement will comprise a trade off between the need to maintain an optical centre of illumination and the practical requirements for driving a pixel of a display.  In a full colour pixel display, the need to maintain an optical centre can be partially or substantially relaxed due to the differences between a full colour arrangement and a monochrome pixel arrangement. There is therefore disclosed a pixel arrangement (30) for a full colour display having a relaxed requirement for maintaining an optical centre of illumination, in addition to disclosing a method for constructing full colour pixel arrangements with relaxed optical centring requirements.

Abstract: A switchgear module is provided that is assembled from one or more molded housing portions to provide a gas-tight volume for the housing of electrical components. The switchgear modules include provisions for assembly of various combinations of switchgear modules into a variety of electrical circuit configurations while maintaining a gas seal of the switchgear modules. In a preferred arrangement, the switchgear module includes bus conductors that are integrally incorporated during the molding of the switchgear module housing and that are accessible from opposite sides of the module. Further, the switchgear module includes integrally molded features for providing access to make electrical interconnections between the bus conductors of adjacently positioned switchgear modules. Thus, the finally assembled and tested switchgear modules with pressurized internal volume may be configured to provide a variety of different electrical circuit combinations of the internal components and are also capable of being reconfigured as desired into different configurations or lineups without the loss of the seal of the interior volume of the switchgear modules. The switchgear module includes a complete internal and integral system to satisfy desirable operating practices to deenergize, test and ground the circuit before working thereon. Specifically, the switchgear module includes an integral indicator with test feature, a visible open gap in the circuit which is readily observable externally to the module, and a ground position for the internal switch to ground the circuit. In a preferred arrangement, an operating mechanism is internal to the module and controls the position of either a loadbreak switch or a disconnect switch between three operable positions, close, open, and ground. The operating mechanism is charged and operated by an operating train that is connected to an operator control.

Filed: 1995-06-08
Abstract: A normally white liquid crystal display is provided with a positively birefringent uniaxial retardation film having a retardation value of from about 100 - 200 nm.      The retardation film is provided on one side of the liquid crystal layer, the liquid crystal being sandwiched between a pair of orientation or buffing films which orient the liquid crystal molecules adjacent thereto in predetermined directions. The optical axis of the retardation film is rotated from about 2° - 20°, most preferably from about 6° - 10° relative to the buffing direction on the opposite side of the liquid crystal layer. This rotation of the retardation film optical axis allows for the high contrast ratio viewing zone of the display to be shifted vertically into either the positive or negative vertical viewing region depending upon the direction of rotation of the retardation film optical axis. Alternatively, biaxial retardation films having similar retardation values may be utilizied according to the teachings of this invention.
