Title: Radially expandable nickel-titanium surgical stent
Inventor: FRANTZEN JOHN J
IPC: A61F2/06
Filed: 1998-09-29
Granted: 2007-11-20
Abstract: A radially expandable surgical stent is provided formed from a shape memory and/or superelastic material such as a nickel-titanium alloy. The stent includes a series of wave-like struts spaced apart by gaps. Each gap is spanned by tie bars at a maximum width portion of the gap or by an angled link or a straight link at a minimum width portion of a gap. Hence, axial expansion or contraction of the stent is avoided when the stent is radially expanded or contracted. Each strut is formed from a series of substantially linear legs joined together by free bends or attachment bends. The legs and bends can be provided with an enhanced thickness to augment resistance of the stent to fracture when radially expanded or contracted. The stent can be radially contracted to a diameter less than one-fourth of its radially expanded configuration when in a martensite phase. The stent returns to a shape memory austenite phase when the stent is unloaded or loaded below its yield strength and has a temperature above its transition temperature. The stent can thus be easily collapsed and implanted within a body lumen for later radial expansion to support the body lumen.

Granted: 2009-05-05
Abstract: A method of producing an ohmic contact to p-type silicon carbide comprising two layers, the first one comprising nickel silicide and the second one comprising titanium carbide is disclosed. The deposited layers are annealed to convert at least a part of deposited metals to nickel silicide and titanium carbide. The contact is formed by reaction between the metals and the semiconductor, and thus the in-situ simultaneous formation of metal silicide and carbide suppress the release of excess carbon at the contact interface. Noble metals may be deposited preferably in between titanium and nickel to improve the contact morphology.

Title: Supported metallocene catalyst and olefin polymerization using the same
Inventor: OH JAE-SEUNG
IPC: C08F110/02
Filed: 2000-03-09
Granted: 2009-09-08
Abstract: The present invention relates to a metallocene compound having a functional group that facilitates the preparation of the supported metallocene catalyst for olefin polymerization and the olef in polymerization process using the same. The present invention utilizes a reaction of the functional group of a ligand such as acetal, ketal, tertiary alkoxyalkyl, benzyloxyalkyl, substi-tuted benzyloxyalkyl, monothioacetal, or monothioketal with highly reactive silica dehydroxylated above 600 .degree.C. The metallocene compounds in this invention are strongly supported on the inorganic support due to the strong chemical bond of the ligand of the metallocene compound with the silica surface, which leads to minimized leaching of the catalyst during the activation process. There-fore, the supported catalyst of this invention allows the olefin polymerization process to proceed without any fouling in the reactor with a slurry or a gas phase process, and the morphology and bulk density of the polymer produced are much better defined than those produced by conventional methods.

Abstract: A vehicle restraint at a loading dock includes a vertically moving barrier that engages a truck's rear ICC bar to help prevent the truck from accidentally moving too far away from the face of the dock. The restraint includes an inclined barrier actuator with minimal linkage that provides a low-profile stored position. The barrier actuator powers the barrier up to engage the ICC bar and powers the barrier down to a stored position. A compliant coupling provides the barrier with vertical float to allow for incidental vertical movement of the ICC bar, as the truck is being loaded or unloaded of its cargo. The restraint also includes a novel switch actuator that senses whether the ICC bar is properly positioned relative to the barrier.

Title: Medical drainage device with flow restriction feature
Inventor: YAM JACKY
IPC: A61M1/02
Filed: 2000-03-09
Granted: 2009-02-17
Abstract: The present invention provides for a dual port arrangement for a water seal chamber of a drainage device for channeling, and restricting fluid flow through the water seal during normal operation of the device when the patient is breathing normally, while preventing the breach of the water seal during reverse flow conditions when the patient takes a sudden, and deep inhalation. The dual port arrangement comprises a narrow side port and an elongated tunnel port interposed between, and in communication with, both arms of the water seal chamber. The side port has a thin slot configuration that restricts fluid flow communication through the side port, and the back tunnel port defines a low profile, elongated conduit with openings that channel fluid flow between both arms of the water seal chamber. The elongated configuration of the conduit also prevents a steep water gradient from falling below the upper portion of the conduit opening during reverse flow conditions, and breach the water seal.

Abstract: A shade positioning system which employs a wrap spring clutch system includes a shade operator, a shade roller, and an idle end bracket for supporting the shade roller when mounted. The shade operator includes a self-lubricating central hub around which a helical coil spring is wrapped, a manually operated pulley mounted on the wrap spring, and a support bushing to ensure positive engagement of the aforementioned elements. The central hub is composed of a plastic or metal, which allows the smooth rotation of the wrap spring around the hub. The tangs of the wrap spring project substantially radially outward from the spring central axis, and are shaped to accommodate for the coefficient of friction between the hub and the spring. A first preferred spring construction allows for decreased spring surface area to contact the hub. A second preferred spring construction allows for an increased spring surface area to contact the hub. Further, the bushing is provided with a projection which engages the wrap spring due to the weight of the shade. This engagement causes the spring to further grip the hub preventing pulley rotation.

Granted: 2006-08-08
Abstract: Method and apparatus are provided for seamless integration of multiple video projectors. In addition to edge blending, projection artifacts in dark or black image regions caused by residual grays from non-perfect projector black leve ls are reduced. Overlapped and non-overlapped areas of the image are defined and th en the minimum black level of the video signal in non-overlapped areas is boosted without affecting the bright portion of the video signal in order to create uniform black level. The bright portion of the image is then smoothed in the overlapped area wi th seamless edge blending techniques. The resultant projected image may be pass ed through a neutral density filter to lower the base black level of the now uniform overlap and non-overlap black regions. The image may also pass through a physical mask which is hard edged or graded and aligned to less than the overall overlap region and that when used, smooths the edge of transition between the non-overlapped and overlapped regions.

Abstract: A feeder roller apparatus for high speed image scanning equipment, which improves feeding of documents, and in particular short documents, sequentially fed from a stack. The feeder apparatus comprises a PIC roller and an infeed roller which are selectively, independently driven via a dual drive shaft, composed of an inner drive shaft and an outer drive shaft, driven together or selectively, independently by a main motor. An electro-mechanical clutch, when energized is used to drive the PIC roller.        A sensor is provided downstream of the rollers to recognize when a document is being fed. Initially, the clutch is energized, and both rollers are driven. When the first sheet reaches the sensor, the clutch is de-energized, cutting off the drive to the PIC roller. The main motor continues driving only the infeed roller until the first sheet is fed.
