Abstract: Approaches are disclosed for managing aspects of content delivery in a multi-tenant environment. A request buffer can be used to remove correlations between requests and randomly shuffle requests without storing all the requests concurrently. A shuffle sharding algorithm can be used to randomly allocate a subset of resources to different users in order to ensure less than a maximum risk of one user impacting the use of all resources allocated to other users. In some embodiments, separate fleets of resources can be maintained for manifests and video segments to allow for more accurate scaling and customization. Multiple manifests can also be associated with a single endpoint to allow multiple media players to obtain similar content segments from the single endpoint.

Abstract: In all applications of force, all components, internal or external, moving or otherwise, have inertia associated with their mass and geometry. The inertia of the components, internal or external, moving or otherwise, is detrimental to the precision and/or accuracy of the force being applied by and/or to the system, whether the force is applied internally or externally to the system. A motorbased system and/or a method involves mitigating and/or reducing force errors caused by the inertia of the components, internal or external to the system, moving or otherwise, in systems built for the application of force, the forces being internal or external to the system. This is achieved, in part, by addressing the inertial effects of components in the load-application path, including a motor and/or other force-generating devices, force transmitting elements, and carriers of force between a motor and those elements that contribute to force error due to inertial effects.

Abstract: An electro-mechanical system including a power supply, at least one energy storage device and at least a boost circuit, in which the power supply is directly connected to an AC power source and the at least one energy storage supplies power to an electro-mechanical device and its controller. The boost circuit transfers excess power not being used at any given time into the energy storage device to provide an increase in available power comes. This increase in available power stabilizes the power delivery and improves the operation of the device. The device can include at least one motor and at least one motor controller and at least one buck circuit. The power supply, the at least one energy storage and the at least one motor controller can be connected in series.

Abstract: In exemplary embodiments, a caged spring assembly is provided that includes a first end cap, a second end cap, a helical spring, and a locking post. The second end cap is opposite the first end cap. The helical spring extends between the first and second end caps. The locking post is disposed inside the helical spring between the first and second end caps. The locking post allows limited compression of the helical spring and prevents extension of the helical spring beyond a set point.

Abstract: An aircraft electric taxi system diagnostics and prognostics evaluation method, including receiving, with a computer, an electronically recorded first performance parameter of a first electric taxi system of a first aircraft during a taxi operational event at an airport; and comparing the first performance parameter with a first performance factor statistical model generated in response to the first performance parameter and first comparative performance parameters; and calculating a first performance parameter difference based on the comparison.

Abstract: A process for preparing dry powder formulations of a glycopyrronium salt for inhalation that have good stability. The process involves (a) micronising a glycopyrronium salt together with an anti-adherent agent, and (b) admixing carrier particles to form the dry powder formulation.

Abstract: An aircraft taxi control system may include a left main gear (MG) drive motor, a right MG motor, a first motor drive controller configured to produce a left motor torque signal responsively to nose gear angle (NGA) and nose wheel speed (NGS), and a second motor drive controller configured to produce a right motor toque signal responsively to the NGA and the NGS. The left motor torque signal and the right motor torque signal may be coordinated to reduce lateral loading of the nose wheel during a turning maneuver.

Abstract: A method and apparatus for producing gas, for example for propulsion. Propellant grains are segmented, preferably in symmetrically arranged pairs and preferably about a central channel extending longitudinally between the ends of the grains. Longitudinally extending grains may be ignited at one end only of each grain, at both ends, and/or at one or both ends along with at an interior portion of a grain. In order to maintain a relatively constant center of gravity, symmetrically arranged pairs of grains can be ignited simultaneously. In order to produce a desired pressure versus time profile, the number of ignition points on a grain can be varied.

Abstract: A system for regulating the voltage in an electrical distribution system includes a plurality of flywheels, motor/generators, and controllers. Each of the motor/generators is coupled to one of the energy storage flywheels and to the electrical supply system. The motor/generators each supply one or more signals representative of motor/generator operational parameters, and each motor/generator controllers receive one or more of the motor/generator operational parameter signals from each of the motor/generators. In response to the operational parameter signals, the motor/generator controllers each control the operation of one of the motor/generators in either a motor mode or a generate mode, to thereby regulate the electrical supply system voltage and equally share the electrical load between the motor/generators.
