Abstract: YIGSR peptidomimetics and methods for making and using the same are provided. The subject YIGSR peptidomimetics are non-peptidic, biodegradation-resistant molecules that mimic the pentapeptide tyrosine-isoleucine-glycine-serine-arginine (YIGSR) binding site for the 67 kiloDalton (kDa) laminin binding protein (LBP). The subject peptidomimetics include a rigid or substantially rigid non-peptidic scaffold that effectively presents or positions a tyrosine or tyrosine-like group, an isoleucine or isoleucine-like group, a serine or serine-like group, and an arginine or arginine-like group in substantially the same manner as occurs in the YIGSR peptide itself. The subject peptidomimetics find use in a variety of different applications, including diagnostic and therapeutic applications.

Abstract: A radiation curable resin composition suitable for making three dimensional objects comprising at least one epoxy compound, a cationic photoinitiator, wherein the resin composition has a first color or no color before cure and wherein a three dimensional object made from the resin by subjecting the resin to radiation shows a second color which is different from the color of the resin composition before cure.

Abstract: Solid objects are formed in an imagewise layering process in which components of a dispersion are homogenized to form an alloy. Imagewise exposure of the layers to radiation to form an alloy permits separation of the exposed, homogenized regions from non-exposed, non-homogenized regions. As each layer is formed and imagewise homogenized, contiguous layer regions are bonded together to form a homogenized, three-dimensional object which may be separated from surrounding dispersion.

Abstract: An apparatus for fabricating integral three-dimensional objects from successive layers of deformable and photoformable compositions by exposing the layers of the composition through a tensioned, elastomeric transparent film, in a way that the weak bonds between the film and each newly solidified layer are broken by changing the tension on the film, thus allowing a new layer of deformable composition to be introduced between the film and the solidified layer.

Abstract: A data conversion apparatus and method for translating information stored in a first relational database to that stored in a second relational database, and for translating information in a relational database used by a first selected version of a computer program into information stored in a second relational database for use by a second selected version of a computer program. The apparatus and method thus allow the sharing of data by computer systems running different versions of a given software package. The data conversion apparatus includes a first file storage element for storing a first relational database having a plurality of digital records representing information used by a first selected version of a computer program, and a second file storage element capable of storing a second relational database representing at least a portion of the information from the first database for use by a second selected version of the computer program.

Abstract: A method and apparatus, where high viscosity liquids, including pseudoplastic, plastic flow, and thixotropic liquids, as well as gels, semi-solid, and solid materials are viscosity reduced during coating and allowed to increase in viscosity during imaging steps, for use in Solid Imaging applications. Use of these materials and the apparatus improves coating uniformity and final object tolerances.

Abstract: A method for reducing curl in three dimensional computer generated models, created by the sequential exposure of adjacent layers of a photoformable composition, comprising exposing each layer twice, the first exposure being with an image modulated exposure further modulated to produce a series of isolated, anchored islets along the imaged areas, and the second exposure also being image modulated but without the additional modulation, so as to fuse the islets into a continuous solid image.
