Abstract: The invention relates to a method of producing improved feathers (including down feathers) by coating said feathers with coating materials via plasma deposition resulting in coated feathers and down feathers with improved properties such as moisture resistance, hydrophobicity, fill power (loft), and other improved characteristics.

Abstract: A computer system for an inventory management tool using a criticality measure is disclosed. The computer system has a memory, at least one input device, and a central processing unit in communication with the memory and the at least one input device. The central processing unit calculates an amount of existing inventory for one or more parts used to produce a product and determines a lead time to receive the one or more parts. The central processing unit also determines a build time to produce the parts into the product and receives a criticality measure for the product, the criticality measure indicating an order time for delivering the product. Further, the central processing unit adjusts a supply chain process for the parts based on the lead time, the build time, and the criticality measure.
