Abstract: The technology described herein secures input data during communication between an input device and an input destination, such as an application or container. In an aspect, the input device is a keyboard. The technology described herein may enable a keyboard to communicate in a standard mode and a secure mode. In the standard mode, the keyboard communicates like currently available keyboards. In secure mode, the keyboard may provide several security enhancements including the encryption of keystrokes with decryption occurring at the input destination. The security enhancements can include building a secure communication channel between the keyboard and the input destination. The security enhancements can include an attestation to the user that the keyboard is operating in secure mode.

Abstract: Methods, systems, apparatuses, and computer-readable storage mediums are described herein for software application state synchronization across computing environments. A user working in an application at a first state may change computing environments and open the application in a second computing environment at the same state. The first instance of the software application executing on the first computing environment is locked and application specific state information including memory state information scanned from runtime memory or persistent memory, and execution state information from render commands intercepted by an operating system filter, are written to a synchronization file that is stored in the memory system. Application agnostic information is also written to the synchronization file.

Abstract: Software application state synchronization across computing environments to an alternate software application is provided. A user working in a first application executing at a first state on a first computing environment, changes to work at a second computing environment. The user proceeds to work in an alternate application, which executes from the same state on the second computing environment. In response to receipt of a synchronization trigger it is determined that the alternate application is installed on the second computing environment. A synchronization file including a data structure storing first application state information is received from the first computing environment. The alternate application is launched for execution on the second computing environment, and at least a portion of the state information of the first application is applied in the second computing environment for synchronizing execution of the alternate application with the state of the first application.

Abstract: Embodiments are provided for imaging an operating system (OS) by creating a new OS image from an installer OS image copy maintained in durable storage. During the OS imaging, only a subset of OS files from the installer image are fully copied into the new OS image. Placeholder files are created for other files not included in the initial subset of OS files which were determined to be critical for booting of the OS and/or a minimum set of OS functionality. The placeholder files are distinguished from sparse files and are inaccurately presented by the file system as being full copies of the underlying installer OS image. The data for the placeholder files is only copied when requested, on demand, and/or when there is available/unused processing bandwidth that is subsequently identified after rebooting the computing system with the new OS image.

Abstract: Technologies are disclosed for redirecting input/output (“I/O”) requests to virtual hard disks (“VHDs”) to improve network performance and data redundancy. More particularly, files can be encapsulated in remote VHDs and accessed in such a way that the files appear to a local operating system and any local applications to be residing locally. Furthermore, I/O requests redirected to files encapsulated in VHDs may also be redirected to one or more additional VHDs for data redundancy. The redirected I/O requests may be transmitted simultaneously but separately to the additional VHDs in a split stream.

Abstract: A turbine rotor blade that includes: an airfoil defined between a pressure face and a suction face; a tip shroud that includes a seal rail projecting from an outboard surface and, formed thereon, a cutter tooth; and a cooling configuration that includes a cooling channel for receiving and directing a coolant through an interior of the rotor blade. The cooling channel may include fluidly connected segments, in which: a supply segment extends radially through the airfoil; a cutter tooth segment is formed within the cutter tooth of the seal rail; and branching segments formed within at least one of the tip shroud and an outboard region of the airfoil. Each of the branching segments may extend between an upstream port, which connects to the cutter tooth segment, and an outlet port, which is formed on a target surface area, so that the branching segment bisects a target interior region.

Abstract: A proximity transducer system including an eddy current effect proximity probe, a proximity electronics module coupled to the probe, a monitoring system and a two-wire, current interface connecting the proximity electronics module to the monitoring system is disclosed. The proximity transducer system is operative for measuring position and vibration of a component to be monitored. The current interface is made up of a pair of wires, e.g., a twisted pair, and is adapted for providing power to the electronics module and an electrical signal from the proximity electronics module that is representative of (e.g., proportional to) the length of the gap between the probe and the component being monitored. That signal has a DC component that represents a steady state distance and an AC component that represents active movement of the component, such as vibration.
