Patent number: 11939619Abstract: The invention is directed to an engineered yeast including an exogenous nucleic acid encoding a glucoamylase comprising SEQ ID NO:1 and SEQ ID NO:4, or a variant thereof. The engineered yeast are able to provide glucoamylase into a fermentation media and cause degradation of starch material generating glucose for fermentation to a desired bioproduct, such as ethanol. High titers of bioproduct (e.g., 70 g/kg of ethanol) can be achieved, along with low residual glucose levels. Further the yeast exhibit good growth and bioproduct product at temperatures of 32° C. or greater.Type: GrantFiled: March 30, 2022Date of Patent: March 26, 2024Assignee: CARGILL, INCORPORATEDInventors: Chris Miller, Brian Rush, Joshua Dunn, Brynne Stanton

Publication number: 20230335155Abstract: A PZT microactuator such as for a hard disk drive has a restraining layer bonded on its side that is opposite the side on which the PZT is mounted. The restraining layer comprises a stiff and resilient material such as stainless steel. The restraining layer can cover most or all of the top of the PZT, with an electrical connection being made to the PZT where it is not covered by the restraining layer. The restraining layer reduces bending of the PZT as mounted and hence increases effective stroke length, or reverses the sign of the bending which increases the effective stroke length of the PZT even further. The restraining layer can be one or more active layers of PZT material that act in the opposite direction as the main PZT layer. The restraining layer(s) may be thinner than the main PZT layer.Type: ApplicationFiled: June 20, 2023Publication date: October 19, 2023Inventors: David Glaess, Kuen Chee Ee, Long Zhang, Chris Dunn

Patent number: 11781705Abstract: Unique securement devices, usable for example as tripod feet, each feature a bistable spring band encapsulated in an outer skin with a set of optionally magnetic embedments discretely spaced along the band, and a coupler at one end for attachment to a tripod leg or other component. Unique ball and socket joints employ both a snap fit and a secondary retention mechanism to reliably secure together various components, including said securement devices and tripod legs. One joint includes an externally convex and internally concave ball coupler for optional mating with either a larger socket coupler or smaller ball. One joint includes a stabilization sleeve for angularly locking the ball and socket joint. An elongated support, usable as a tripod leg for example, features threaded connection ports usable to either directly mount threaded third-party componentry, or to receive a threaded ball coupler by which socket-equipped componentry can be indirectly attached.Type: GrantFiled: October 15, 2019Date of Patent: October 10, 2023Assignee: North Rim Investment Group Ltd.Inventor: Chris A.

Publication number: 20120179904Abstract: A host computer cloud has a processor and supports a virtual machine. An agent under control of a user is in communication with the cloud over a network. A key management server is in communication with the cloud over a network. The cloud stores the virtual machine in the form of a virtual encrypted disk on a non-volatile storage medium. When commanded by the agent, the cloud requests a disk-wrapping key from the key management server and decrypts the encrypted disk using the disk-wrapping key.Type: ApplicationFiled: November 14, 2011Publication date: July 12, 2012Applicant: SafeNet, Inc.Inventors: Chris Dunn, Russell Dietz, Philip Snyder, Alan H.
