  • Publication number: 20230419244
    Abstract: Logistics are optimized for delivering a product within a product distribution network. A computer receives order data, the order data includes order information and a delivery location of a product ordered by a user. The order data further includes an order history of the user including order returns or cancelations. Using data analytics, the order data is analyzed to determine a logistics plan for the delivery of the product. A probability of return of the product is calculated, and a probability of re-order of the product is calculated. As part of the logistics plan and based on the analyzing of the order data, a recommended storage facility is generated for a second delivery location resulting from a re-routing of the delivery of the product, in response to the order being canceled.

  • Patent number: 10023939
    Abstract: A unique sequence of steps is provided to reduce contaminants along one or more surfaces and faces of gold evaporative sources without deleteriously impacting the structure of the gold evaporative sources. Edges are deburred; contaminants are successfully removed therealong; and surface smoothness is substantially retained. The resultant gold evaporative source is suitable for use in evaporative processes as a precursor to gold film deposition without the occurrence or a substantial reduction in the likelihood of spitting by virtue of significantly reduced levels of contaminants, in comparison to gold evaporative sources subject to a standard cleaning protocol.

  • Patent number: 9761420
    Abstract: The present invention relates to novel and improved high purity diffusion bonded copper (Cu) sputtering targets having a Cu purity level of 99.9999% (6N) or greater. The target assemblies of the present invention exhibit sufficient bond strength and microstructural homogeneity, both of which are properties previously considered mutually exclusive for conventional 6N Cu target assemblies. The grain structure is characterized by an absence of alloying elements and the bonded interface is generally flat without any type of interlayer or interlocking arrangement.
