Abstract: A rotor blade for a turbomachine includes an airfoil having a leading edge, a trailing edge, a root, and a tip. The airfoil defines a chord extending from the leading edge to the trailing edge and a span extending from the root to the tip. A first particle-filled damper is positioned within the airfoil between fifty percent of the chord and one hundred percent of the chord.

Abstract: In devices that determine levels of substance use, a substance level in a test sample provided to the testing device by a test subject is determined. A sequence of images are captured to include a portion of the face of the test subject providing the test sample and a display of the testing device. A value indicative of the substance level detected within the test sample is determined. A validity indicator indicating validity of the value indicative of the substance level is determined. A current location is determined. The value indicative of the substance level, the validity indicator, and the current location are sent to a remote server.

Abstract: A method for sharing information has an assertion associated therewith such that the receiving communication device is able to verify the assertion without the sender revealing underlying data demonstrating the validity of the assertion. The assertion is derived from underlying data input to a pre-provisioned first algorithm. The assertion is encapsulated in a first data object by a PGE that controls an environment in which the first algorithm is executed. A first proof is generated that is configured to verify that the first algorithm used the underlying data to produce the assertion when provided to a PVE along with the first data object. The underlying data is excluded from the first proof and the first data object such that privacy of the underlying data is maintained. The information, the first proof and the first data object are sent to the receiving communication device from the sending communication device.

Abstract: A system, such as a system of a computing resource service provider, detects changes to a pipeline template package that encodes information associated with application code and infrastructure that may be utilized as part of deploying the application code in stages of a pipeline. An infrastructure template that is usable to provision an execution environment may be generated for a corresponding stage of the development, and may be utilized as part of a process for provisioning an execution environment which may, for example, run tests to verify the quality of the application code.

Abstract: A method for removing diatomaceous earth and contaminants from a filter, and for filtering liquid using diatomaceous earth is provided. Embodiments of the method can include a washdown process, a backwash process, and a filtering process. Some embodiments can include one or more filter cartridges with cartridge tubes to increase flow during the backwash process. Some embodiments can also include a backwash sprayer to disturb contaminants during the backwash process.

Abstract: Methods of curing tobacco that reduce the levels of TSNAs and/or improve leaf quality are described herein.

Abstract: A method for achieving consensus amongst a distributed and decentralized set of computers, devices or components in a network interacting via messaging is presented. The method does not rely on the availability of an overall ledger that is consulted for every interaction. Rather, the interacting components communicate directly with each other via messages that contain proofs of consistency that may be used to achieve local consistency amongst the interacting components. Local consistency guarantees global consistency. For regulatory and record keeping purposes, use of an overall ledger may be contemplated for regulatory and record keeping purposes. The latter may be updated by the interacting devices via an asynchronous updating mechanism.

Abstract: Techniques are presented for managing a deployment pipeline using an inheritable and extensible source code template—generally referred to as a live pipeline template (LPT). As described, live pipeline templates may be used to manage deployment pipelines which, in turn, are used to launch, maintain, and update the services and systems used to host and provide computing services.

Abstract: Levels of substance use, location, and vital signs are remotely monitored for a subject. In one embodiment, the system includes a testing device and a communication device. The testing device obtains a breathalyzer sample from a test subject and determines a substance level. The communication device reports the substance level to a remote monitoring station. In addition, location and camera functions of the communication device can report additional information for verification and system integrity. In other embodiments, the system can be incorporated into an ankle bracelet for monitoring movement of an individual or into a vehicle system to prevent operation while impaired.

Abstract: A dry powder inhalation treatment for pulmonary arterial hypertension includes a dose of dry particles comprising greater than 25 micrograms of treprostinil enclosed in a capsule. The dry particles can include treprostinil, a wetting agent, a hydrophobicity modifying agent, a pH modifying agent and a buffer. A method of treating a patient having pulmonary arterial hypertension includes providing a patient a dry powder inhaler, providing the patient at least one capsule for use in the dry powder inhaler, the capsule including at least 25 micrograms of treprostinil.

Abstract: A latch assembly includes a chassis, a latch bolt moveably mounted on the chassis and having a closed position for retaining a striker and an open position for releasing the striker, a pawl having an engaged position at which the pawl is engaged with the latch bolt to hold the latch bolt in the closed position and a disengaged position at which the pawl is disengaged from the latch bolt, thereby allowing the latch bolt to move to the open position, an eccentric arrangement defining an eccentric axis and a pawl axis remote from the eccentric axis. The eccentric arrangement is rotatable about the eccentric axis, and the pawl is rotatable about the pawl axis. When the pawl moves from the engaged position to the disengaged position, the eccentric arrangement rotates in one of a clockwise and a counter-clockwise direction about the eccentric axis.

Abstract: A method includes applying a force to elastically deform at least a portion of a superalloy turbine blade from a relaxed, initial position to an elastically deformed position. The at least a portion of the superalloy turbine blade has a curvature in the elastically deformed position not present in the relaxed, initial position. A hole is drilled generally span-wise through the at least a portion of the superalloy turbine blade in the elastically deformed position, and when the force is released, the superalloy turbine blade returns to the relaxed, initial position and the hole takes on a hole curvature within the at least a portion of the superalloy turbine blade.

Abstract: A rail vehicle compressor system comprises a compressor, driven by an electrical machine via a drive shaft, for producing compressed air for at least one compressed air tank. The electrical machine is activated at least indirectly via a control device for operating the electrical machine at least one nominal speed between a maximum speed and a minimum speed. At least one pressure sensor determines the pressure for the control device and is disposed in a compressed-air-carrying line downstream of the compressor. A final control element for continuously influencing the speed of the electrical machine is disposed between an electrical supply and the electrical machine, wherein the control device controls activation of the final control element. A method for controlling the compressor system is also provided, wherein, the compressor is operated at a variable speed in between the maximum speed and the minimum speed based on rail vehicle operating state.
