Computer-based bit error simulation for digital wireless communications
(United States Patent and Trademark Office, 1993-08-03)
A communications stimulation system allows a user to perform a quantitative or subjective test of digital baseband devices over wireless channels using actual measured or modeled propagation data. The digital wireless ...
Mixing process for generating in-situ reinforced thermoplastics
(United States Patent and Trademark Office, 1993-07-06)
A method for blending polymeric materials includes the steps of producing a melt stream of a first polymer from a first extruder (12) and a separate melt stream of a second polymer from a second extruder (14), joining the ...
Portable computer with display unit connected to system unit through conducting hinge
(United States Patent and Trademark Office, 1993-08-17)
An electrically conductive hinge provides for the transmission of electrical power and signals between a pivotally connected display unit and system unit of a portable computer and eliminates cable connections between the ...
Spatially-weighted two-mode optical fiber sensors
(United States Patent and Trademark Office, 1993-06-29)
Tapered two-mode optic fibers are used as sensors with sensitivity varying as a function of length. The optical fiber sensors act as vibrational-mode filters thereby performing initial signal processing of the sensor signal. ...

Systems, methods, and computer-readable media for generating a data set are provided. One method includes generating a data set based on input data using a plurality of brokers. The method further includes receiving a ...
Fiber materials for manufacturing fiber reinforced phenolic composites and adhesives with nucleophilic initiators positioned on the fiber surfaces
(United States Patent and Trademark Office, 2000-07-18)
Fiber reinforced thermosetting matrix materials are advantageously created using fibers that are coated with a coating containing a nucleophilic initiator or have a surface treatment which creates a nucleophilic initiator ...
Preparation of open chain poly(reissert compounds)
(United States Patent and Trademark Office, 1990-05-29)
An open chain poly Reissert can be formed by the initial reaction of an aromatic dialdehyde (e.g., terephthaldicaboxaldehyde) and primary amine (e.g., methylamine) to form a reaction product which is then reacted with an ...
Methods of treating preeclampsia
(United States Patent and Trademark Office, 1996-12-03)
Methods are provided for the diagnosis and treatment of patients with increased risk of gestational hypertension or preeclampsia. The methods involve measuring serum M-CSF levels, and administration of M-CSF.
Method of producing prepolymers from hydroxyalkyl lignin derivatives
(United States Patent and Trademark Office, 1992-04-07)
A method of producing prepolymeric materials from lignin is disclosed. The method uses lignin which has been hydroxyalkyl modified, such that the lignin is substantially non-phenolic and solvent soluble and/or liquid. The ...
Rare earth manganate films made by metalorganic decomposition or metalorganic chemical vapor deposition for nonvolatile memory devices
(United States Patent and Trademark Office, 1997-04-29)
A ferroelectric memory device having a perovskite thin film of a rare earth manganate and processes for manufacturing the same. The perovskite thin film layer has properties consistent with high quality nonvolatile memory ...
