CPC Class B33Y

Disclosed herein are a three-way authentication apparatus and method in a cloud environment. The three-way authentication method in a cloud environment includes performing, by a control device and a service device, mutual authentication through an IF-1 interface, performing, by the control device and a function server, mutual authentication through an IF-2 interface, requesting, by the control device, the function server to issue an authentication token for authentication between the service device and the function server, and delivering an authentication token issued by the function server to the service device, and performing, by the service device, mutual authentication with the function server using the delivered authentication token through an IF-3 interface.

Archiving local logical units of data storage (LUNs) to cloud storage, wherein the local LUNs reside on local physical storage of a data storage system, includes establishing a mirror between a local LUN and a cloud-backed LUN backed by cloud physical storage of a cloud storage system, the mirror making data contents of the cloud-backed LUN identical to data contents of the local LUN. Once the mirror is established, then (a) a stub is deposited on the local LUN to direct subsequent IOs to the cloud-backed LUN, and (b) local physical storage of the local LUN is released for allocation to other local LUNs. Subsequent IOs to the local LUN are satisfied from the cloud-backed LUN. An archived LUN can be restored by a restore process.

Actuator systems for oral-based appliances utilizing transducers which are attached, adhered, or otherwise embedded into or upon a dental or oral appliance to form a hearing aid assembly. Such oral appliances may be a custom-made device which receives incoming sounds and transmits the processed sounds via a vibrating transducer element. The transducer element may utilize electromagnetic or piezoelectric transducer mechanisms and may be positioned directly along the dentition or along an oral appliance housing in various configurations.

Disclosed herein is a surgical guide tool for use in total hip replacement surgery. The surgical guide tool may include a customized mating region and a resection guide. The customized mating region and the resection guide are referenced to each other such that, when the customized mating region matingly engages a surface area of a proximal femur, the resection guide will be aligned to guide a resectioning of the proximal femur along a preoperatively planned resection plane.

A medical device comprising a structure formed of polyvinyl alcohol.

An automotive armrest includes an elastic core defining a patterned array of channels extending therethrough such that the elastic core exhibits a predetermined target vertical stiffness and a predetermined target lateral stiffness different than the predetermined target vertical stiffness. The automotive armrest also includes a skin arranged with the elastic core.
