Abstract: A flash chamber sized to receive the effluent discharged from a polyolefin reactor during normal operation of the reactor and during a reactor dump, advantageously eliminating a reactor dump tank or alternate flash tank from the equipment outlay of a polyolefin manufacturing process. The flash chamber is sized to hold at least the polyolefin solids discharged from the reactor. A condenser fluidically coupled to an overhead portion of the flash chamber is sized to condense the flow rate of vaporized hydrocarbon (e.g., diluent, monomer, etc.) discharged overhead from the flash chamber during normal operation and during the reactor dump.

Abstract: A system integrates standards-defined multimedia storage system and an Internet browser. In one example, Universal Resource Locator (URL) information corresponding to web sites accessible by the browser is stored in fields within the DVD data. When a user actuates a DVD element that has a corresponding URL, the web browser displays information from that site. When the user actuates an HTML menu or other browser-implemented feature, the DVD system accesses a portion of the DVD data specified in the menu. This arrangement provides for two-way communication, i.e., HTML in the browser is able to control DVD content and vice-versa. Having WWW information embedded in the DVD brings a number of benefits, the foremost of which is the ability to write a “one size fits all” template web page that can interrogate the DVD for URL information and present WWW content corresponding to the URL synchronized with the DVD information.

Abstract: There is provided a system for comparing the phase characteristics of three generated clock signals, each having a unique phase relationship with an original clock signal, with the original clock signal and to select a signal based on the proximity of the phase characteristic of the three signals to the original signal. The selection of a clock signal that most closely approximates the original significantly reduces lock time when attempting to synchronize an internal clock with an external clock. Additionally, there is provided a method for comparing three clock signals with an original clock signal and selecting from the three clock signals one that is approximately in phase with the original clock signal.
Abstract: Provided is a method of image-guided navigation comprising determining a final navigated point in a three-dimensional reconstructed coordinate system based at least partially on two or more navigated points in a coordinate system associated with a two-dimensional array of image pixels and without specifying a coordinate of each of the two or more navigated points in a direction orthogonal to the two-dimensional array of image pixels, wherein each of the two or more navigated points is for a different position of a C-arm gantry. Also provided is an image-guided navigation system.
Abstract: A technique is presented for establishing a patient's BMD using a dual-energy X-ray imaging system. In the technique, the dual-energy X-ray imaging system utilizes a slit collimator to expose a series of portions of a region of interest within a patient with X-rays of two different energies. A flat-panel digital X-ray detector detects the X-rays passing through the patient's region of interest and produces data representative of the intensity of the X-rays reaching the detector. The image intensity data is corrected for scatter based on identifying the regions of the image intensity data that are produced from scatter only, and not primary X-rays. A first-order derivative of the image intensity data is used to identify these regions. A value for the intensity of the scatter at the boundary of the scatter-only region is established.

Abstract: A mobile dual-energy X-ray imaging system is presented. The mobile dual-energy X-ray imaging system is a digital X-ray system that is designed both to acquire original image data and to process the image data to produce an image for viewing. The system has an X-ray source and a portable flat-panel digital X-ray detector. The system is operable to produce a high energy image and low energy image, which may be decomposed to produce a soft tissue image and a bone image for further analysis of the desired anatomy. The system is disposed on a carrier to facilitate transport. The imaging system has an alignment system for facilitating alignment of the flat-panel digital detector with the X-ray source. The imaging system also comprises an anti-scatter grid and an anti-scatter grid registration system for removing artifacts of the anti-scatter grid from images.

Abstract: Methods for fabricating a non-planar transistor. Fin field effect transistors (finFETs) are often built around a fin (e.g., a tall, thin semiconductive member). During manufacturing, a fin may encounter various mechanical stresses, e.g., inertial forces during movement of the substrate and fluid forces during cleaning steps. If the forces on the fin are too large, the fin may fracture and possibly render a transistor inoperative. Supporting one side of a fin before forming the second side of a fin creates stability in the fin structure, thereby counteracting many of the mechanical stresses incurred during manufacturing.
