  • Publication number: 20150079327
    Abstract: A method for fabricating custom surface reflectance and spatially-varying bi-directional reflectance distribution functions (BDRFs or svBRDFs). The 3D printing method optimizes micro-geometry to produce a normal distribution function (NDF) that can be printed on surfaces with a 3D printer. Particularly, the method involves optimizing the micro-geometry for a wide range of analytic NDFs and simulating the effective reflectance of the resulting surface. Using the results of the simulation, the appearance of an input svBRDF can be reproduced. To this end, the micro-geometry is optimized in a data-driven fashion and distributed on the surface of the printed object. The methods were demonstrated to allow 3D printing svBRDF on planar samples with current 3D printing technology even with a limited set of printing materials, and the described methods have been shown to be naturally extendable to printing svBRDF on arbitrary shapes or 3D objects.

  • Patent number: 8920897
    Abstract: Disclosed is a heat exchanger pressure test shield to protect observers from a shell and tube heat exchanger plug ejection during a hydrostatic pressure test. The shield provides a transparent high impact resistant shield material clamped between two annular rings. This shield material is isolated from the annular rings by a flexible gasket, which allows slight movement of the shield material upon impact, which is necessary to prevent failure. The heat exchanger pressure test shield is mounted to the channel cover flange, after removal of the channel cover, with several studs passing through an adjustable slot, enabling attachment to a range of heat exchanger diameter sizes. The heat exchanger pressure test shield, with adjustable slot attachment, enables visual inspection of tube plugs during pressure testing at a lower cost, while significantly improving the safety of the observer.

  • Patent number: 8895128
    Abstract: The present invention is an improved corkboard consisting of a small, circular, moveable and removable tack landing pad which is designed to adhere to a flat surface such as a wall or computer by an adhesive strip or to a metal surface like a refrigerator or thing cabinet via a magnetic strip. This landing pad is designed to receive papers of various sizes, shapes, and stock through puncture with a standard push pin tack without damaging walls. The landing pad consists of two components—(1) an outer donut-shaped shell that is sealed at its base and is contoured inward to a narrowing angle at its tack receiving face and (2) an inner foam core. The outer shell operates to both enclose and compress the foam core. This core compression affords the foam greater tack gripping ability as well as enhanced durability by quickly regaining its original shape upon tack removal.
