US10817325B2	Moving storage volumes for improved performance Data volumes hosted for customers in a multi-tenant environment can be moved advantageously throughout the environment to improve performance and reduce cost. A data volume can serve I/O for a virtual machine instance, and it can be advantageous for the virtual machine and the data volume to be in the same network locality, or share at least some of the same network state and interconnection. Since there is limited capacity in a network locality, data volumes not attached to virtual machines can be moved to other locations in the environment.

For example, the multiple instances are installed on multiple user devices, and are associated with user features describing the installed instances. In addition, the initial workspace recommendation engine receives a set of new user features associated with the newly installed application instance. The classifier classifies the available user interface component based on a similarity between the new user features and the user features describing the installed instances. Based on the classification, the initial workspace recommendation engine recommends the available user interface component for inclusion in or omission from the initial workspace of the newly installed instance.
US10817312B2	Programming model for performant computing in document-oriented storage services Object-oriented application languages often provide resources to applications for accessing objects stored in the volatile application memory region, and, separately, for packaging objects for persistent storage and network transport by serialization and deserialization involving a storage format. However, this design creates discrepancies between the application language and storage format, and depends on affirmative serialization and deserialization by the application. Presented herein are techniques for providing object access to objects involving persisting the objects as documents in a document store, where such persistence occurs automatically upon object creation and updating, and where such objects are stored in a language format integral to the application language (e.g., when a JavaScript application creates an object, the objects are automatically stored as documents of the document store in a JavaScript Object Notation (JSON) format). This design enables various advantages in efficiency, flexibility, and seamless interaction between the application and the objects.

A compiler recognizes different types of link configurations and provides in a target program specification occurrences of a target primitive for executing a function for each occurrence of a data element flowing over a link of the second type. A computing node initiates execution of the target program specification, and determines at runtime, for components associated with the occurrences of the target primitive, an order in which instances of tasks corresponding to the components are to be invoked, and/or a computing node on which instances of tasks corresponding to the components are to be executed.

Each of the plurality of magnetic poles comprises at least a section with a radial magnetic direction in respect of the axis (130, 230) and at least a section with a magnetic direction angled between a radial direction and a tangential direction in respect of the axis (130, 230), wherein the combined length of the sides of the plurality of permanent magnets cover less than 75% of the circumference of the cylindrical structure. The outer rotor has a cylindrical structure (120, 220) surrounding the plurality of magnetic poles (105, 205), and the cylindrical structure is made of a magnetic susceptible material for conducting a magnetic flux between the plurality of magnetic poles (105, 205) The inner rotor (110, 210) is made of a magnetic susceptible material and free from permanent magnetic material, wherein the inner rotor is formed with multiple radial projections (111, 211) acting as salient inner rotor poles distributed around the axis (130, 230) of the inner rotor. The invention also relates to a coupling with the above mentioned coupling features.

US10815996B2	Compressor and method for controlling the rotational speed thereof The present invention relates primarily to a method for controlling the rotational rate of a compressor, which controls, in particular, the rotational rate of a rotating compression element of the compressor. The invention furthermore relates to a compressor, e.g. a compressor for generating pressurized air. The compressor is to be operated at a rotational rate, when in operation, with a mean value that is at least as high as a minimum mean value, in order to ensure the functionality of the compressor. According to the method, a temporally variable target rotational rate of the compressor that is necessary for obtaining a temporally variable output performance from a compressor is determined. In accordance with the invention, a lower rotational rate limit is raised if the temporal mean of the variable target rotational rate is lower than the minimal mean value for the rotational rate of the compressor.
US10815994B2	Mutual rotating scroll compressor A mutual rotating scroll compressor includes: a first frame fixed to a casing; a second frame provided with an interval between the first frame and the second frame, a compression space being provided between the first frame and the second frame; a first scroll rotatably supported by the first frame and coupled to a driving motor to rotate in the compression space; a second scroll engaged with the first scroll to rotate about the second frame, the second scroll and the first scroll forming a compression chamber in the compression space; and a bearing housing including a housing part, including a boss accommodation part to which the second scroll is rotatably coupled, and a hinge lug which extends from the housing part and is movably coupled to the second frame.
US10815992B2	Scroll compressor having Oldham coupling with key portions and different width key gaps A scroll compressor includes a movable scroll having first key grooves, a stationary member having second key grooves, and an Oldham coupling provided between the movable scroll and the stationary member. The Oldham coupling is movable with respect to the stationary member along a first axis direction, and with respect to the movable scroll along a second axis direction. The second axis is orthogonal to the first axis and passes through a center of gravity of the Oldham coupling. The Oldham coupling has an annular body portion, at least two first key portions fitted into the first key grooves, and second key portions fitted into the second key grooves. Key gaps are formed between outer peripheral surfaces of the first key portions and inner peripheral surfaces of the first key grooves. The key gaps have first gaps and second gaps wider than the first gaps.
US10815990B2	Paint sprayer pump cartridge A fluid dispensing system includes a motor housing and a piston pump assembly connected to the motor housing. A motor is mounted within the motor housing. The piston pump assembly includes a pump housing, a cartridge having a first end that extends into a second end of the pump housing, a piston that extends into a first end of the pump housing and the first end of the cartridge, and a packing stack within the cartridge and adjacent an inner surface of the cartridge and through which the piston extends. The cartridge is configured to be removed from the pump housing, and removal of the cartridge removes the packing stack from within the pump housing while leaving the pump housing connected to the motor housing.
