Abstract: The present invention provides a method and apparatus for enhancing and recognizing connected and degraded text. The enhancement process comprises filtering a scanned image to determine whether a binary image value of an image pixel should be complemented, determining whether complementing the value of thepixel reduces the sharpness of wedge-like figures in the image, and complementing the binary value of the pixel when doing so does not reduce sharpness. The recognition process may comprise determining primitive strokes in a scanned image, segmenting the scanned image into sub-character segments based on the primitive strokes, identifying features which characterize the sub-character segments, andcomparing identified features to stochastic models of known characters and determining an optimum sequence of known characters based on the comparisons through the use of Viterbi scoring and level building procedures.

Granted: 2008-02-19
Abstract: An absorbent structure, such as a sanitary napkin, having abody facing liquid acquisition layer and a garment facing fluidly adaptive component capable of continuously and simultaneously dynamically conforming or adapting the liquid acquisition layer to the body of the wearer in response to pressure. The fluidly adaptive component is filled with a fluid in an amount such that when pressure is applied to the surface of a first portion of the fluidly adaptive component, a volume of fluid is transferred to a second portion of the fluidly adaptive component and causes the surface of the second portion of the fluidly adaptive component to bulge or expand. The fluidly adaptive component is fluid impervious and is adjacent to and in dynamically responsive contact with the liquid-acquisition layer. In a preferred embodiment, the fluidly adaptive component further comprises a barrier layer wherein two superposed fluid impermeable layers define a sealed fluidly adaptive component between them.  The fluidly adaptive components of the present invention, when incorporated into an absorbent structure, dynamically urge a portion of the body-facing liquid-acquisition layer toward the body of the user.

Title: Exterior decorative surround molding module
Inventor: VAUGHAN ROBERT A
IPC: B60J10/79
Filed: 1997-01-20
Granted: 2000-10-24
Abstract: Providing a module and a method of installing the module to a vehicle having a window opening for a translational glass pane supported and guided by a glass run channel. The module is comprised of a one-piece surround molding fully surrounding and generally defining the perimeter of the window opening.  A glass run channel is secured to the surround molding. Fasteners are attached to the surround molding and attach the module to a flange on the vehicle. A belt line outer seal and one or more gimp seals may also be attached to more fully integrate the module.  The module is fully assembled prior to being attached to a vehicle during final assembly, the surround molding supporting the glass run channel rather than having the glass run channel attached to a flange of the vehicle. Further, a method of installing the module in a reduced number of operations along the final assembly line is disclosed which provides improved control over the fit and finish of the multiple part within the module, and reduces labor time associated with the final assembly line.

Title: Condensate discharge device
Inventor: OIKE TADASHI
IPC: F16T1/38
Filed: 1997-03-12
Granted: 2000-11-21
Abstract: A condensate discharge device which prevents metal ions from attaching and depositing on the condensate discharge port surface. An inlet, a condensate discharge port, and an outlet are formed in a valve casing, which valve casing includes an upper casing and a lower casing. A valve seat member having a discharge passage is screwed into the lower casing. The discharge passage includes a first orifice having a smaller opening area than the condensate discharge port, and a second orifice having a smaller opening area than the first orifice. A movable member is mounted through the second orifice. On end of the movable member rests on one side of the second orifice, and another end is located on the other side of the second orifice. Condensate flows slowly through the condensate discharge port, preventing metal ions from attaching there, and flows rapidly through the second orifice. Any metal ions attaching to the second orifice are removed by moving action of the movable member, which moving action is caused by flow of condensate around the movable member.

Abstract: Arcing faults in an ac current are detected by apparatus which is responsive to a predetermined randomness in step increases in the current to eliminate false tripping caused by regularly occurring discontinuities produced by loads such as dimmers. A signal conditioner generates a bandwidth limited di/dt signal having pulses produced by the step increases in current. In one embodiment, a first tracking circuit tracks the envelope of the di/dt signal with a first time constant. A second tracking circuit also tracks the di/dt envelope, but with a second, shorter time constant. An arcing fault is indicated if the second tracking signal falls to a predetermined fraction of the fist tracking signal. This circuit may be used alone to detect arcing faults or to increase the sensitivity to arcing faults over dimmers of a circuit which responds to a time attenuated integrated valve of the pulses in the di/dt signal. In another embodiment, the di/dt envelope signal is subtracted from the magnitude of the pulses before they are applied to the time attenuated integrator, but with the subtraction time delayed to preclude attenuation of the first pulse.

Abstract: A system and apparatus for the measurement of absolute biaxial birefringence of plastic materials is described. The materials which must be at least partially transparent can be constituted of one or several similar or dissimilar layers.  In the latter case, the birefringence of each material can be determined. The technique uses a multiwavelength white light source that provides at least two beams projected at different angles of incidence on the sample. The beams pass through first polarizers before they are incident on the sample and through second polarizers after they have passed through the sample. The beams are then directed to a detector for measuring each beam intensity or transmittance as a function of wavelength for the incident angles at different times, and are analyzed using nonlinear regressions to determine retardation. By the knowledge of the thickness of the material, the absolute biaxial birefringences are calculated for any specific wavelength. The regression procedure incorporates the material dependent optical constants for the calculations and to discriminate between different materials for multilayer samples.
