Patent number: 6652902Abstract: Boronic acid containing polymers are used to form bioinert gels and multilayer surface structures. These polymers form crosslinked hydrogels, which are highly swollen in water. The crosslinking can either be chemical or physical.

In addition, a method of curing a UV-curable coating is disclosed. The method includes the steps of spraying the formulation onto the exterior of a substrate, surrounding the substrate in an inert gas enviromnent, and irradiating the substrate with ultraviolet radiation from a doped medium pressure mercury vapor lamp.Type: GrantFiled: May 2, 2000Date of Patent: December 26, 2000Assignee: Callaway Golf CompanyInventors: Steven C. Crast, Ramon Buella Dineros

Patent number: 6132799Abstract: Process for producing an electronic card comprising a micromodule inserted in the card body, wherein one layer of the body contacting the micromodule is of polymerized plastic material. A mixture containing a low viscosity liquid monomer is spread on a substrate used for producing the card and the polymerization of the monomer is initiated with a polymerization initiator. The process is particularly useful for the production of microcircuit cards such as contactless cards and advantageously uses an acrylic or methacrylic compound.Type: GrantFiled: October 26, 1999Date of Patent: October 17, 2000Assignee: Gemplus Card InternationalInventors: Isabelle Corniglion, Jean-Christophe Fidalgo, Christian Leriche

Patent number: RE37875Abstract: 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.Type: GrantFiled: November 13, 2000Date of Patent: October 15, 2002Inventor: John A.
