Title: Advanced compatible polymer wood fiber composite
Inventor: SEETHAMRAJU KASYAP V
IPC: C08J5/06
Filed: 1996-06-03
Granted: 2008-09-09
Abstract: The invention relates to a composition comprising a thermoplastic polymer and wood fiber composite that can be used in the form of a linear extrudate or thermoplastic pellet to manufacture structural members. The polymer, the fiber or both can be modified to increase compatibility. The wood fiber composite structural members can be manufactured in an extrusion process or an injection molding process. The linear extrudate or pellet can have a cross-section of any arbitrary shape, or can be a regular geometric. The pellet can have a cross-section shape having a volume of at least about 12 mm3. Preferably the pellet is a right cylindrical pellet having a minimum radius of about 1.5 mm and a minimum length of 1 mm weighing at least 14 mg. The invention also relates to an environmentally sensitive recycle of waste streams. The polymer and wood fiber composite contains an intentional recycle of a waste stream comprising polymer flakes or particles or wood fiber. The waste stream can comprises, in addition to polymer such as polyvinyl. chloride or wood fiber, adhesive, paint, preservative, or other chemical stream common in the wood-window or door manufacturing process, or mixtures thereof. The initial mixing step before extrusion of the composite material insures substantial mixing and melt contact between molten polymer and wood fiber. The extruded pellet comprises a consistent proportion of polymer, wood fiber and water. During the extrusion, water is removed intentionally to dry the material to a maximum water content of less than about wt-% based on the pellet weight. To make a structural unit, the pellet is introduced into an extruder or injection molding apparatus wherein, under conditions of temperature and pressure, the composite pellet material is shaped into a useful cross-section. Alternatively, the extruded thermoplastic mass, in the form of a elongated linear extrudate without a pelletizing step, can be immediately directed after formation into an extruder or injection molding apparatus.

Granted: 2000-07-04
Abstract: An endocardial lead (12) for implantation in a right heart chamber (RV) for responding to blood pressure and temperature and providing modulated pressure and temperature related signals to an implanted or external hemodynamic monitor (100) and/or cardiac pacemaker or pacemacker/cardioverter/defibrilator. The lead (12) has a sensor module (20) formed in its distal end and is coupled to a monitor (100) that powers a sensor circuit in the sensor module. The sensor module is formed with a pickoff capacitor (Cp) that changes capacitance with pressure changes and a reference capacitor (Cp) that is relatively insensitive to pressure changes. The sensor circuit provides charge current that changes with temperature variation at the implant site, alternately charges and discharges the two capacitors, and provides timing pulses having distinguishable parameters at the end of each charge cycle that are transmitted to a demodulator (150). The demodulator (150) detects and synchronizes the timing pulses and derives pressure and temperature analog voltage values representative of the intervals between the timing pulses which are digitized and stored in the monitor. The monitor may also be coupled with other sensors (106, 152) for measuring and storing related patient body parameters, e.g. blood gas, ECG, and patient activity.

Title: Active pulse blood constituent monitoring
Inventor: KIANI-AZARBAYJANY ESMAIEL
IPC: A61B5/00
Filed: 1996-06-04
Granted: 2008-08-19
Abstract: A blood glucose monitoring system (100) is disclosed which provides for inducing an active pulse in the blood volume of a patient.  The induction of an active pulse results in a cyclic, and periodic change in the flow of blood through a fleshy medium (310) under test. By actively inducing a change of the blood volume, modulation of the volume of blood can be obtained to provide a greater signal to noise ratio.  This allows for the detection of constituents in blood at concentration levels below those previously detectable in a non-invasive system.  Radiation which passes through the fleshy medium is detected by a detector (320) which generates a signal indicative of the intensity of the detected radiation. Signal processing is performed on the electrical signal to isolate those optical characteristics of the electrical signal due to the optical characteristics of the blood.

Title: Method for acquisition and processing of nuclear magnetic resonance signals for determining fluid properties in petroleum reservoirs having more than one fluid phase
Inventor: GEORGI DANIEL T
IPC: G01V3/32
Filed: 1999-02-09
Granted: 2002-02-05
Abstract: A method for determining intrinsic transverse relaxation time of a first mobile phase in a porous medium using nuclear magnetic resonance measurement sequences. The sequences are measured at first and second wait times. At least two different interecho spacing times are used for each wait time. The first and second wait time are selected to provide different magnetization recoveries of the first phase, and are selected to be longer than the longitudinal relaxation time of a second mobile phase.  For the measurements made at the first interecho spacing time, components of signals in the measurements corresponding to the first phase are separated from components corresponding to the second mobile phase by determining differences between the signals measured at the first and at the second wait times. The step of separating is performed for each of the interecho spacing times. An apparent transverse relaxation time of the first mobile phase is calculated from the separated components for each one of the interecho spacing times. A relationship of the apparent transverse relaxation time with respect to the interecho spacing time is determined, and the intrinsic relaxation time is calculated from the relationship. Viscosity of the first mobile phase can be determined from the intrinsic relaxation time.

Title: A method and system for device virtualization based on an interrupt request in a dos-based environment
Inventor: WEIR ANDREW P
IPC: G06F13/10
Filed: 1997-09-08
Granted: 2001-04-24
Abstract: A technique for providing device virtualization in an MS-DOS based operating environment (212), using an interrupt request (e.g., a non-maskable interrupt), is described. The technique includes executing an application on a processor within the MS-DOS based operating environment (212) and, when the application attempts to address the device to be emulated, causing a processor interrupt to occur. In response to the interrupt, the processor executes code representing the virtualization of a device. The code for servicing the interrupt and emulating the device are written in protected mode-code, stored in the extended memory area (114), and made available by making appropriate entries into the interrup descriptor tables (318) for the protected-mode context established for the DOS extender (410). The entries made into IDT  (318) for the protected-mode context established for the DOS extender are accomplished by intercepting communications between the DOS extender and the virtual control program interface (314).
