Patent number: 12459000Abstract: Methods of coating a substrate are provided. In an exemplary embodiment, a coating composition is applied to the substrate with a high transfer efficiency applicator to produce a coating layer, where the high transfer efficiency applicator and the substrate remain spatially separate while the coating composition is applied. A droplet of the coating composition expelled from the high transfer efficiency applicator has a particle size of about 10 microns or greater. The coating composition has a viscosity of from about 1,000 to about 1,000,000 centipoise when the coating composition is subject to a shear rate of about 0.1 reciprocal seconds (s?1). However, the coating composition is non-Newtonian such that a coating composition viscosity decreases when the shear rate is increased to the coating composition. The coating layer is impinged with a gas such that a coating layer surface moves upon impingement with the gas.Type: GrantFiled: December 20, 2022Date of Patent: November 4, 2025Assignee: AXALTA COATING SYSTEMS IP CO., LLCInventors: Shih-Wa Wang, Cameron Stevens, James Neal, Carmen Flosbach, Michael S.

Publication number: 20040068716Abstract: The invention provides a compiler for generating assembly or configuration instructions from source code for an integrated circuit architecture of a plurality of different IC architectures. The source code is represented as a plurality of nodes of an abstract syntax tree. For each target architecture, a plurality of concrete instruction tiles are generated as concrete classes corresponding to and inheriting from a plurality of function tiles. Each function tile is implemented as an abstract class, represents a corresponding function, such as an ADD or MULT function, and implements a matching operation for the corresponding function. The compiler includes an instruction selector, formed as an abstract class, which implements a matching function and instruction generation for the abstract syntax tree by calling the corresponding matching operations of the concrete instruction tiles, inherited from the plurality of function tiles.Type: ApplicationFiled: October 4, 2002Publication date: April 8, 2004Applicant: Quicksilver Technology, Inc.Inventor: Cameron Stevens
