Publication number: 20240143439Abstract: A method for adjustable error correction in a storage cluster is provided. The method includes determining health of a non-volatile memory of a non-volatile solid-state storage unit of each of a plurality of storage nodes in a storage cluster on a basis of per flash package, per flash die, per flash plane, per flash block, or per flash page. The determining is performed by the storage cluster. The plurality of storage nodes is housed within a chassis that couples the storage nodes as the storage cluster. The method includes adjusting erasure coding across the plurality of storage nodes based on the health of the non-volatile memory and distributing user data throughout the plurality of storage nodes through the erasure coding. The user data is accessible via the erasure coding from a remainder of the plurality of storage nodes if any of the plurality of storage nodes are unreachable.Type: ApplicationFiled: November 22, 2022Publication date: May 2, 2024Inventors: John D.

Patent number: 10641778Abstract: The present invention provides a system and method for assessing the fidelity of a synthetic peptide population including interrogating a population of peptide features in the presence of a receptor having an affinity for a plurality of binder sequences. A first amino acid is at a defined position within a first one of the binder sequences, and the population of peptide features includes a first control peptide feature synthesized to have an amino acid sequence including the first one of the binder sequences. The system and method further includes detecting a signal output characteristic of an interaction of the receptor with the first control peptide feature. The signal output is indicative of the fidelity of incorporation of the first amino acid into the first control peptide at the defined position within the first one of the binder sequences.Type: GrantFiled: August 10, 2016Date of Patent: May 5, 2020Assignee: ROCHE SEQUENCING SOLUTIONS, INC.Inventors: Ryan Bannen, Sarah Barilovits, Jigar Patel, Eric Sullivan, John Tan

Patent number: 10183424Abstract: A product to be shipped is placed on a platform. A conveyor belt moves the product and platform toward a packaging station where mold forms at least define a space which encloses the product. Expanding foam is then injected via injector lines into the space. Once the expanding foam has at least partially hardened, the mold forms may be retracted and the package is moved to a next station for at least one of finishing, loading, or storing. The foam thus becomes the shipping package for the product. This eliminates the need to store shipping containers of multiple standardized sizes and shapes, and to fill the standardized shipping containers with dunnage. The mold forms also provide for customized exterior shapes for the shipping package.Type: GrantFiled: December 18, 2014Date of Patent: January 22, 2019Assignee: Amazon Technologies, Inc.Inventors: Gregory Karl Lisso, Jon Stuart Battles, John Tan, Samuel Christopher Uhlman
