Publication number: 20010046600Abstract: A core crush resistant prepreg for use in making a fiber reinforced composite panel structure is provided. The prepreg comprises a woven fabric consisting essentially of carbon fiber tow strands impregnated with a hardenable polymeric resin composition. Typically the fabric has an areal weight of from about 180 to about 205 grams per square meter. The prepreg has an average fiber tow aspect ratio of less than about 15.4, a prepreg thickness of at least about 0.245 mm, and a prepreg openness of at least about 1.2 percent but less than about 6.0 percent. Preferably, the resin composition is predominantly viscous in nature and has a tan &dgr; value of between 0.9 and 2.0 at an elevated temperature between 70° C. and 140° C., and an average epoxy functionality of greater than 2.0. A method for evaluating core crush resistance properties of a prepreg is also provided.Type: ApplicationFiled: November 30, 2000Publication date: November 29, 2001Applicant: HEXCEL CORPORATIONInventors: Hao-Ming Hsiao, Shaw Ming Lee, Robert Albert Buyny, Cary Joseph Martin

Patent number: 6321731Abstract: The invention comprises a strategy and method for phase shifting intake and exhaust valve timing relative to crankshaft position as a function of engine operating variables, whereby valve overlap is delayed to obtain improved fuel economy resulting from a late intake valve closing to reduce pumping work during the intake stroke. The exhaust gases are drawn into the combustion cylinder of the engine during the intake stroke, which reduces oxides of nitrogen in the exhaust gas and reduces unburned hydrocarbons. Improved thermal efficiency and reductions in oxides of nitrogen are achieved as the combustion charge is diluted at higher loads by an external exhaust gas recirculation system, thereby combining the effects of exhaust gas recirculation and dual equal variable camshaft timing to obtain fuel economy benefits that cannot be achieved with either a conventional EGR system acting alone or dual equal variable camshaft timing acting alone.Type: GrantFiled: January 19, 2000Date of Patent: November 27, 2001Assignee: Ford Global Technologies, Inc.Inventors: Stephen George Russ, Robert Albert Stein

Patent number: 6142726Abstract: An apparatus for loading, chamfering and unloading a ceramic or ceramic/polymer substrate for electronic components. An automatic part loader moves substrates in a row as a unit, using a frangible pin to push the parts. The part loader separates the first of the substrates from the rest, and a load pedestal pushes the first substrate up into a loading/unloading nest. The load pedestal is mounted on rods so that the substrate may move laterally to center itself in the nest. The nest then rotates to load the substrate onto a movable process pedestal. The chamfering apparatus includes a pair of spaced, rotatable cutting spindles for chamfering edges and corners on the substrate.Type: GrantFiled: February 16, 1999Date of Patent: November 7, 2000Assignee: International Business Machines CorporationInventors: Robert Peter Westerfield, Jr., Thomas Gerard Jantz, Robert Paul Kuder, II, David Clyde Linnell, Robert Albert Meyen

Patent number: 5881929Abstract: A mounting cup having a plastic film or laminate provided on the top outwardly facing surface thereof, at least adjacent the pedestal portion of the mounting cup, for mating with a skirt of a spray button to provide a sufficient seal between those two components during charging of a pressurized container with a propellant. The perimeter dimension of the skirt is preferably sized to be slightly smaller than the perimeter dimension of the pedestal portion of the mounting cup so that the skirt is slightly expanded upon engagement with the mounting cup. Due to this arrangement, the skirt at least partially bites into the plastic laminate, provided on the top surface of the mounting cup, to provide the sufficient seal between those two components.Type: GrantFiled: April 25, 1997Date of Patent: March 16, 1999Assignee: Summit Packaging Systems, Inc.Inventor: Robert Albert Coerver, Jr.

Patent number: 5878131Abstract: Acoustic dialers are widely used to dial telephone numbers by generating a pair of DTMF tones for each key being depressed. Non-linearities in telephone systems, acoustic dialer loudspeakers, and telephone microphones may cause interfering tones to be produced due to mixing of generated DTMF tones. These interfering tones are especially problematic when they are near the frequencies of the DTMF tones and have similar amplitudes. When these interfering tones are received by a receiver decoder, the decoder may be unable to distinguish the interfering tones from the DTMF tones, and consequently the decoder may reject the DTMF tones received. The present invention prevents these types of rejections by generating a supplemental tone in addition to the normal DTMF tones. This supplemental tone attenuates the interfering tones so that receiver decoders can distinguish the interfering tones from the DTMF tones.Type: GrantFiled: November 18, 1996Date of Patent: March 2, 1999Assignee: AT&T CorpInventor: Robert Albert Boie

Patent number: 5847690Abstract: A unitary display and sensing device integrates liquid crystal display module elements of a liquid crystal display module for detecting input on a flat panel display screen with the capability for digitizing the detected inputs. In accordance with an illustrative embodiment of the present invention, display elements of a liquid crystal display module are modified to sense input on the display screen. An electrical signal is applied to modified display elements of the liquid crystal display module so that contact with a surface portion of the display screen produces an output signal indicative of its location. The integrated display and sensing device is active matrix addressed for finger input, but may also incorporate display systems for active pen input.Type: GrantFiled: October 24, 1995Date of Patent: December 8, 1998Assignee: Lucent Technologies Inc.Inventors: Robert Albert Boie, Richard Alan Gottscho, Allan Robert Kmetz, Richard H.

Patent number: 5834709Abstract: The present invention provides a position-sensing system which employs sensors incorporating magnetoresistive materials. The position of a magnetic information input member is determined through the resistance change of the magnetoresistive sensor in response to the magnetic field from the magnetic information input member. Exemplary magnetoresistive materials are lanthanum manganites having high magnetoresistive ratios. Two-dimensional position sensing systems for graphics tablets are also described.Type: GrantFiled: April 28, 1994Date of Patent: November 10, 1998Assignee: Lucent Technologies Inc.Inventors: Greg E.

Patent number: 5780830Abstract: Disclosed is a system and method for reading and decoding distorted data, e.g., bar code label or other symbology data, by fitting a scanned signal model j(t, .theta.), using a Deterministic Expectation-Maximization (DEM) algorithm, to the measured or detected data signal y(t). The DEM algorithm, which is a novel variation of the conventional Expectation-Maximization (EM) algorithm, enables the system and method according to the invention to determine the values of a plurality of parameters .theta. defining the scanned signal model j(t, .theta.) as it is being fitted to the measured data signal y(t). Based on these values, characteristic information such as data elements or symbols encoded within the image data are generated using conventional signal processing techniques. The use of the DEM algorithm advantageously deblurs the signal by reducing the effects of intersymbol interference. In an alternative embodiment, the DEM algorithm is supplemented by a conventional zero crossings decoding technique.Type: GrantFiled: July 24, 1996Date of Patent: July 14, 1998Assignee: Lucent Technologies Inc.Inventors: Robert Albert Boie, William Turin
