Granted: 2014-04-29
Abstract: An efficient technique is provided for determining a portion of a document corresponding to a captured image. Areas of a document in which the pattern is at least partially obscured are identified. A reference pixel in the image is selected, and an offset between the pixel and the pattern is determined. A pixel-by-pixel comparison is then made of the image with the document such that the reference pixel is only compared with locations in the document that are both within the identified areas and have the determined offset from the pattern. The comparison with the highest correspondence between the image pixels and the electronic document then identifies the position of the reference pixel relative to the electronic document.

Abstract: An arrangement for reducing pressure inside a circuit breaker caused by gas produced during an electrical interruption event, including a base, an interrupter assembly, and a trip unit base. A structure having a surface is positioned in the base at an angle relative to a vent opening of the interrupter assembly. The trip unit base includes a complementary structure opposing the structure to form a cavity. The base includes a chamber area adjacent to an opening of a vent chute that leads away from the circuit breaker. During an electrical interruption event, hot explosive gas, carbon, and molten metal debris are directed away from the vent opening of the interrupter assembly along the angled surface of the structure and toward the opening of the vent chute. In this manner, pressure in the circuit breaker is reduced during an electrical interruption event, and undesirable buildup of debris is reduced.

Title: Container handling system
Inventor: KELLEY PAUL
IPC: B65B53/00
Filed: 2004-07-30
Granted: 2011-05-17
Abstract: A system for processing a simplified plastic container (C) that is to be filled with a hot product includes the step of blow-molding parison to form a container body, where the container body has a neck, a base, a side surface relatively free of structural geometry that surrounds an interior of the container body and, prior to being filled with the hot product, a projection (12) extending from the container body. After the container body is filled with a hot product in a production line, the neck of the filled container body is capped with a cap and then, the container body is cooled. During the cooling operation, the hot product is contracted so that the projection extending from the container can be pushed (P) into the container body like a traditional push-up so that the resultant, filled and cooled container body is relatively free of structural geometry.

Abstract: A Terminator by Tapering Fiber Optic (herein after named TermTaper.TM.) made directly using a single mode optical fiber to reduce the back reflection in an installed optical fiber link, which occurs when a guided incident optical signal encounters an index of refraction change at a glass-air transition. The single mode fiber has at one end, a first length of exposed fiber which is obtained by way of stripping the jacket from that portion of fiber. The bare fiber is positioned in a suitable heating set in order to enable a biconical taper to be formed on that portion of bare fiber. The bare fiber with the first formed biconical taper is repositioned in the heating set in order to enable additional biconical tapers to be formed on the same portion of bare fiber. The concatenated biconical tapers contribute to obtain a return loss of better than 55 dB for any guided optical signal that propagates through the TermTaper. The TermTaper is assembled in any type of suitable mounting device.

Abstract: A trusted Java virtual machine provides a method for supporting tamper-resistant applications, ensuring the integrity of an application and its secrets such as keys. The trusted Java virtual machine verifies the integrity of the Java application, prevents debugging of the Java application, and allows the Java application to securely store and retrieve secrets. The trusted Java virtual machine environment comprises a TrustedDictionary, a TrustedBundle, an optional encryption method for encrypting and decrypting byte codes, and an underlying trusted Java virtual machine. The encrypted TrustedDictionary protects data while the TrustedBundle protects programming code, allowing applications to store secret data and secure counters. The application designer can restrict TrustedBundle access to only those interfaces that the application designer explicitly exports. The open source code may optionally be encrypted. Secrets required by the open source programming code of the application are encrypted in TrustedDictionary.

Title: Cerenkov x-ray detector for portal imaging
Inventor: PANG GEORDI G
IPC: G01T1/28
Filed: 2007-01-02
Granted: 2014-09-30
Abstract: The present invention provides a practical design of a megavoltage x--ray detector with both high quantum efficiency (QE) and high resolution. The x-ray detector includes an optical-fiber taper (OFT) made from a large number of optical fibers, each of which is aligned with the incident x-rays from an x--ray source hitting a top surface of the optical fiber taper. The optical- fiber taper is a matrix of optical fibers with the core material made of, e.g., silica and coated with a cladding glass or polymer such that light created within the core of each optical fiber will be guided to the bottom ends of the fiber with the ends of the fibers at the bottom being optically coupled to and optical image read-out device. Each optical fiber in the optical fiber taper is fully aligned with the incident x-ray source so that x-rays entering the top of the fiber travel directly towards the bottom of the same fiber. This alignment (or focusing) of the optical-fiber taper towards the x-ray source can be achieved by an extra coating at the bottoms of the optical fibers so they have a larger diameter than the other top ends of the fibers.

Title: Multiple-angle retroreflectometer
Inventor: AUSTIN RICHARD L
IPC: G01N21/55
Filed: 2006-02-27
Granted: 2012-05-01
Abstract: A system and method for measuring the photometric retroreflectivity of materials. The system comprises a light source and a first optical pathway along which an illumination light beam travels originating from the light source, and ending at a retroreflective surface to be measured. A second optical pathway is provided along which a retroreflected beam travels back from the retroreflective surface to an aperture array that selects multiple annular areas to be further directed to multiple detectors, one detector for each annular area selected by the aperture. Each detector has a filter for the determination of photometric retroreflectivity. The retroreflected light reaching the detectors produces currents proportion to the intensity of the light. A high-gain current-to-voltage amplifier is used to provide voltage signal to an analog-to-digital converter that converts a voltage to a digital number. A processor is electrically coupled to the analog-to-digital converter with an accompanying memory on which is stored operating logic adapted to determine the photometric intensity of a predetermined pattern of the retroreflected beam incident to the array of apertures and detectors which defines the retroreflected light which propagates from the retroreflective surface at a predetermined observation angle.
