  • Patent number: 6304326
    Abstract: An optical measurement system for evaluating a reference sample that has at least a partially known composition. The optical measurement system includes a reference ellipsometer and at least one non-contact optical measurement device. The reference ellipsometer includes a light generator, an analyzer and a detector. The light generator generates a beam of quasi-monochromatic light having a known wavelength and a known polarization for interacting with the reference sample. The beam is directed at a non-normal angle of incidence relative to the reference sample to interact with the reference sample. The analyzer creates interference between the S and P polarized components in the light beam after the light beam has interacted with reference sample. The detector measures the intensity of the light beam after it has passed through the analyzer.

  • Patent number: 6301314
    Abstract: Branch metric is calculated by a branch metric calculating circuit 21 on the basis of an input signal. ACS processing to select path of high likelihood on the basis of the branch metric to output state metric is carried out by an ACS circuit 22. Select information obtained by this ACS processing is stored into a path memory circuit 25. Normalization processing of all state metrics are carried out by a normalization circuit 23 on the basis of whether or not only one state metric outputted by the ACS processing is a set value determined in advance. The normalized state metrics are stored into a state metric memory circuit 24. Maximum likelihood decoding judgment processing for selecting maximum likelihood path is carried out by a maximum likelihood decoding judgment circuit 26 on the basis of select information stored in the path memory circuit 25.

  • Patent number: 6281191
    Abstract: New compositions and methods for treating patients suffering from hepatitis-C, AIDS, aberrant apoptosis which include N-acetyl-D-glucosaminyl(&bgr;-1-4)-N-Acetyl-muramyl-L-ananyl-D-isoglutamine (GMDP) of at least 98% purity and provided either alone, as an active ingredient of blastolysine, or in combination with an aminosugar such as N-acetyl-glucosamine(NAG). The high purity GMDP has a decreased amount immunogenic impurities and demonstrates cell protection as opposed to solely immunostimulatory effects, while a synergistic cell protective effect is exhibited when GMDP in combined with NAG. The new compositions modulate FasL mediated apoptosis while simultaneously stimulating TNF-&agr; production and further selectively inhibiting TNF-&agr; receptor p55 (TNFR1), providing a treatment for patients suffering from hepatitis-C, AIDS or aberrant apoptosis.

  • Patent number: 6278519
    Abstract: An optical measurement system is disclosed for evaluating samples with multi-layer thin film stacks. The optical measurement system includes a reference ellipsometer and one or more non-contact optical measurement devices. The reference ellipsometer is used to calibrate the other optical measurement devices. Once calibration is completed, the system can be used to analyze multi-layer thin film stacks. In particular, the reference ellipsometer provides a measurement which can be used to determine the total optical thickness of the stack. Using that information coupled with the measurements made by the other optical measurement devices, more accurate information about individual layers can be obtained.

  • Patent number: 6269473
    Abstract: A software modeling environment is presented that supports the development and execution of software that can be dynamically configured. This is achieved by introducing a design-time object modeling construct called a dynamically configurable type (DCT) that supports the subdivision of an object into a plurality of subsets of semantics and allows dynamic merging of these semantic subsets together in different combinations in order to allow the resultant object to exhibit different semantics over time to serve different purposes. Specific process modeling constructs are included which take advantage of this semantic merging capability. Also included are other supporting design-time and run-time constructs and services. One embodiment of the present invention allows this software modeling environment to be integrated into a standard software development environment, enhancing the modeling capabilities already present.

  • Patent number: 6249881
    Abstract: A method for debugging an application on an embedded processor using a debug monitor service routine (debug ISR) and allowing critical interrupts to be transparently serviced is provided. The method enters and runs a debug monitor service routine transparently such that the application program being debugged is unaware of the monitor. A debug interrupt is completely transparent to the application software that runs on the embedded processor and is therefore non-maskable. In addition, when entering the debug ISR, shadow registers and the global interrupt disable bit (if they exist) are not be altered, which preserves the monitor's transparency to the application. Once the debug monitor is entered, a context save may be performed if needed and the monitor may proceed to enable interrupts if necessary.

  • Patent number: 6246468
    Abstract: An integrated system generates a model of a three-dimensional object. A scanning laser device scans the three-dimensional object and generates a point cloud. The points of the point cloud each indicate a location of a corresponding point on a surface of the object. A first model is generated, responsive to the point cloud, that generates a first model representing constituent geometric shapes of the object. A data file is generated, responsive to the first model, that can be inputted to a computer-aided design system.

  • Patent number: 6245319
    Abstract: Agents for enhancing the contrast in a diagnostic ultrasound procedure comprise colloidal dispersions of the liquid-in-liquid type, i.e., emulsions or microemulsions, in which the dispersed liquid phase is a liquid having a boiling point below the temperature of the animal to be imaged and which therefore undergoes a phase change from a dispersed liquid to a highly echogenic dispersed gaseous foam or kugelschaum following administration to the animal. The liquid state of the dispersed phase allows one to manufacture extremely stable, pharmaceutically acceptable emulsions with particle sizes typically below 1000 nm. The gaseous state at body temperature yields highly echogenic microbubbles, typically below 10,000 nm in diameter, which are effective as ultrasound contrast agents. Intravenous, intraarterial, oral, intraperitoneal, and intrauterine dosage forms, methods of administration, and imaging techniques are described.

  • Patent number: 6231543
    Abstract: A dilation catheter having a catheter shaft with an inner lumen for receiving a guidewire and an inflatable balloon member located at the distal portion of the shaft in fluid communication with the inner lumen. The catheter includes a distal seal disposed within the inner lumen of the shaft. The distal seal allows for movement of the guidewire relative to the inner lumen, while also providing for a fluid tight seal around the guidewire, independent of fluid pressure within the lumen, thereby both restricting a patient's blood from passing into the inner lumen and restricting media from the inner lumen from passing into the patient's bloodstream. A valve is located along the catheter shaft and adapted to engage the guidewire and provide for a fluid tight seal around the guidewire when fluid under pressure is applied to the interior of the balloon member.
