Abstract: A tubular intraluminal prosthesis includes a PTFE or ePTFE tubular structure such as a graft, and a tubular diametrically deformable stent circumferentially surrounding the tubular structure. The diametrically deformable stent includes a polymeric coating which allows for attachment to the tubular graft structure and enhances the biocompatibility and integrity of the composite prosthesis.

Abstract: The invention disclosed includes a head gear to be worn when it is desirable to have an indication of the wearer's head motion or position. The head gear may be incorporated into an existing article of head wear. The incorporation may be permanent, or the head gear may be alternatively attached to various articles of head wear. Integral with the head gear are motion and/or position sensing devices to indicate the motion or position of the wearer's head. The data from the sensors may be fed into a digital processor to process the sensed data and derive a signal indicative of the wearer's head motion or position. Some embodiments employ a programmable processor to adapt the head gear to a variety of applications. The signal indicative of head motion or position may be fed into an indicator to provide the wearer with a recognizable feedback signal indicative of head motion or position.

Abstract: The present invention encompasses the recognition that vectors utilized in molecular biology need not be provided as single intact molecules but rather can be assembled from fragments containing functional elements, or portions thereof. In certain preferred embodiments of the invention, vector fragments are linked together simultaneously with the linkage of vector and insert sequences to one another.

Abstract: The present invention provides an improved system for linking nucleic acids to one another. In particular, the present invention provides techniques for producing DNA product molecules that may be easily and directly ligated to recipient molecules. The product molecules need not be cleaved with restriction enzymes in order to undergo such ligation. In preferred embodiments of the invention, the DNA product molecules are produced through iterative DNA synthesis reactions, so that the product molecules are amplified products. The invention further provides methods for directed ligation of product molecules (i.e., for selective ligation of certain molecules within a collection of molecules), and also for methods of exon shuffling, in which multiple different product molecules are produced in a single ligation reaction. Preferred embodiments of the invention involve ligation of product molecules encoding functional protein domains, particularly domains naturally found in conserved gene families.

Abstract: An electronic performance support system is provided for creating individualized courses of instruction to each user. An authoring mechanism is used to create at least one knowledge base relating to a particular topic. An assessment mechanism evaluates each user's knowledge on a particular topic and devises a course of instruction based on the assessed knowledgeability of each user. After interacting with the assessment mechanism, each user navigates through a corresponding, individualized course of instruction. Each individualized course of instruction includes data items selected from a learning mechanism and a research library. The system may include a communication medium through which users are able to communicate with each other.

Abstract: A flexible trowel has a compliant coupling between the handle and the blade. In the preferred embodiment, the handle is pivotally mounted to the elongated shaft extending from the planar blade for rotation in a plane generally perpendicular to the blade. The pivot pin extends transversely through a longitudinal recess in the handle. The handle is biased upward by a helical compression spring seated in a transverse passage in the handle and adjustably preloaded by a follower nut threaded on a bolt axially restrained in the end of the transverse passage by a retainer cap.

Abstract: This invention relates to a stable pesticidal microemulsion formulation comprising from about 0.01 to about 25% by weight of an insect growth regulator, for example methoprene, S-methoprene, hydroprene and/or S-hydroprene, and from about 0.1 to about 5.0% by weight of an active ingredient, for example pyrethroids or permethrins, and from about 3 to 50% by weight of one or more surfactants with a hydrophile-lipophile balance value of 6 or higher, and from about 25 to 98% by weight of water wherein the insect growth regulator and active ingredient are dispersed in the surfactant(s) forming an oil phase which is in turn dispersed in water and forms discrete micelles in the range of about 0.001 to about 0.5 micrometers. This invention also teaches a method of applying the stable pesticidal microemulsion on animals to control ticks and fleas.
