Abstract: A graph-based clinical concept mapping algorithm maps ICD-9 (International Classification of Disease, Revision 9) and ICD-10 (International Classification of Disease, Revision 10) codes to unified Systematized Nomenclature of Medicine (SNOMED) clinical concepts to normalize longitudinal healthcare data to thereby improve tracking and the use of such data for research and commercial purposes. The graph-based clinical concept mapping algorithm advantageously combines a novel graph-based search algorithm and natural language processing to map orphan ICD codes (those without equivalents across codebases) by finding optimally relevant shared SNOMED concepts. The graph-based clinical concept mapping algorithm is further advantageously utilized to group ICD-9/10 codes into higher order, more prevalent SNOMED concepts to support clinical interpretation.

Abstract: A saw guide pad seal enables recycling of the coolant/lubricant used in a lumber sawing operation. The saw guide pad seal directs the coolant to coolant return chambers. The coolant return chambers have a negative pressure developed from the motion of the saw blade or provided by a vacuum pump or blower, and return the coolant to the coolant tank. A heat-exchanger is optionally used to control the temperature of the coolant, providing more consistent operation of the saw, and a filter is optionally used to remove contaminants before the recycled coolant is provided to the saw blade(s).
