Abstract: A multiple lumen catheter having a soft, tapered multiple lumen distal tip for insertion into a body vessel. One of the lumens is sized to pass over a guidewire such that the catheter can be inserted into the body vessel using the Seldinger technique. At least one medical implement lumen is used for placement or positioning of a biomedical sensor or other medical implement. For example, at least one optical fiber passing through the medical implement lumen may transmit and receive light at the distal tip for measuring oxygen saturation of the blood. The catheter may have a cylindrical catheter body to which the soft distal tip attaches. The soft tip reduces the possibility of vessel or tissue puncture and abrasion. The tip is constructed of a soft plastic or pliable material that yields easily when force is applied.

Abstract: The present invention provides a method, system, and computer program product for adaptive database buffer memory management using dynamic Structured Query Language (SQL) statement cache statistics. The method comprises: using SQL statement cache statistics to infer page re-use. The method further comprises: determining a use ratio of an SQL statement; comparing the use ratio of the statement to a threshold value; if the use ratio is less than the threshold value, setting a reclaim page attribute of the statement indicating a low likelihood of page re-use of pages referenced by the statement; and, if the reclaim page attribute of the statement is set: setting a quick reclaim attribute of each page read from disk by the statement; and after each page is released by the statement, placing the page in a buffer pool free list, wherein a memory location of the page in a buffer pool memory is immediately available for re-use.

Abstract: A system and method for analyzing predicate usage and proposing solutions to improve query performance. The system comprises a system for collecting performance statistics for database queries; an aggregation system that organizes the performance statistics based on predicate combinations used in the database queries;. and an evaluation system that compares the performances of queries having similar predicate combinations. Further features include a problem identification system that identifies a predicate, which when added to a query, results in a low performing query, and a solution proposal system that automatically proposes a solution to address the low performing query.

Abstract: The present invention provides a method for performing local due diligence for accepting certificates. The method creates override certificates which add or modify at least one attribute of a certificate issued by a third party for a remote user, based upon due diligence performed locally. In this manner, finer control than accepting or rejecting a certificate is provided to a local user. The local user can also accept certificates absent a trusted third party. The method thus adds flexibility in the acceptance of certificates in a network.

Abstract: A wireless communications device includes an integrated antenna assembly that provides signals associated with multiple functions to the wireless communications device. The integrated antenna assembly includes an integrated antenna housing coupled to a radiotelephone housing and multiple antennas. The integrated antenna housing can include a first antenna that provides GPS signal reception for a GPS receiver and a second antenna that provides communications signals to and from a radiotelephone processor in the radiotelephone housing. The first and second antennas can be mounted on an antenna backing having a first face and a second face. The first and second antennas may be located on the same face of the antenna backing or on opposite faces of the antenna backing. The integrated antenna assembly also can include a third antenna located between the first and second antennas.

Abstract: A method and system for structuring an object in security policies of a computer system includes: receiving a request to access a virtual volume with a virtual name; mapping the virtual name to the real object; and providing the real object. The method and system uses virtual objects which map to real objects in a computer system. The access control mediator grants or denies access to a virtual object using a discretionary or a mandatory policy. A virtual name is mapped to a real object. This mapping is transparent to the subject. In this manner, security policies can be enforced over objects stored in file systems without regard to the policies of the file systems. The system can also be used as a gateway to remote file systems built on top of existing file systems. These advantages provide more flexibility in controlling a subject's access to real objects.

Abstract: The method for configuring encryption strengths for data includes: providing a piece of the data with a sensitivity level; authenticating a remote user with a clearance level for accessing the data; selecting an encryption strength for the piece of the data based on the clearance level of the remote user, if the clearance level of the remote user allows access to the piece of the data with the sensitivity level; encrypting the piece of the data; and providing access to the encrypted piece of the data to the remote user. Remote users have varying levels of clearance to access data. Data is assigned varying sensitivity levels. Each clearance level allows the remote user to access data at that sensitivity level or below. The strength of the data encryption is based upon the remote user's clearance level or a requested session sensitivity level. Access control to data is thus more flexible.

Abstract: A process for efficiently drawing subdivision surfaces. The present invention operates within a computer system for visually displaying 3 dimensional (3D) surfaces on a display. The present invention pulls polygons from a polygon mesh of a 3D surface. The polygons are stored into a 2 dimensional array such that the vertices of the polygons occupy nodes of the 2 dimensional array and are readily accessed. The polygons are subsequently divided into a plurality of resulting polygons. The resulting polygons are then sent to a graphics pipeline, wherein the graphics pipeline renders the resulting polygons into a 3D image on the computer display.

Abstract: The present invention provides a process for making an elastomeric web. Generally stated, the process includes moving a first web (26) along an appointed machine-direction (28) of the process, and delivering a plurality of elastomeric strands (30) moving along the machine-direction. The elastomeric strands (30) have been elastomerically stretch to an elongation of at least about 50 percent, and the plurality of elastomeric strands (30) have been laterally distributed along an appointed cross-direction (32) of the process. The elastomeric strands (30) are positioned at a spaced distance (34) from the first web (26), and an adhesive is applied to the elastomeric strands (30) and the first web (26) while the elastomeric strands are at the spaced distance (34) from the first web (26). A second web (36) is laminated to the first web (26) with the elastomeric strands (30) sandwiched between the first and second webs to provide an elastomeric laminate, composite web (24) attached together with the adhesive.

Abstract: The present invention relates to modifying the properties of a metal matrix composite body by a post formation process treatment and/or a substantially contiguous modification treatment. The post formation process treatment may be applicable to a variety of metal matrix composite bodies produced by various techniques, and is particularly applicable to modifying the properties of a metal matrix composite body produced by a spontaneous infiltration technique. The substantially contiguous modification process may also be used primarily in conjunction with metal matrix composite bodies produced according to a spontaneous infiltration technique. Particularly, at least a portion of the matrix metal of the metal matrix composite body and/or the filler material of the metal matrix composite body is modified or altered during and/or after the formation process.
