  • Patent number: 10771468
    Abstract: Approaches provide for mandatory access controls and account identification masking controls in an electronic environment. For example, a customer can configure a client device to access an API gateway which acts as a proxy for a resource in a resource provider environment. Requests for resources or services can be redirected to the API gateway. A registered function may be triggered when the request is received and may filter the request. After filtering, the request can be forwarded on to the actual API endpoint to access the requested resource. From the client's perspective, the resource is being accessed directly, and from the resource's perspective, it is being accessed by the proxy. This layer of indirection enables data to be protected preemptively, rather than waiting for an undesirable condition to exist and then reactively attending to the issue.

  • Patent number: 10740151
    Abstract: Systems, methods, and computer-readable media are disclosed for systems and methods for parallelized forensic analysis using cloud-based servers. Example methods may include generating a first request for one or more notifications in a notification queue, where the one or more notifications include a first notification indicative of a first data input at a datastore, determining a first data type of the first data input, and generating a second notification indicative of the first data type. Some example methods may include determining that a first software component is subscribed to notifications for the first data type, sending the second notification to the first software component, determining a first output of the first software component, where the first output comprises a set of extracted data from the first data input, and sending the set of extracted data to the datastore.

  • Patent number: 10550842
    Abstract: A rotary piston compressor is disclosed, comprising a housing having an epitrochoidal shaped inner bore, peripheral inlet and exhaust ports located in the bore, and a rotary piston rotatably mounted within the housing. The central portion of each rotary piston flank is configured such that, at the closest point between the flank central portion and the housing between the exhaust port of the trailing compression cycle and the inlet port of the leading compression cycle, the radial spacing between the rotary piston flank and the housing is maintained such that the volumes enclosed by the rotary piston on either side of the closest point in the respective trailing and leading compression cycles are substantially sealed from one another. The end portions of each rotary piston flank are configured such that radial spacing between the rotary piston flank and the housing exceeds that between the central portion and the housing.

  • Publication number: 20190196886
    Abstract: A visual scripting system can provide support for handling event-specific messages received through an event messaging system. The messaging system can provide event messages over one or more event buses that have a determined behavior context. An event node of a visual scripting system can enable a developer to specify event handlers to detect specific types of event notifications sent on a specified event bus, as well as specific actions to be taken in response to those event notifications, such as to send additional event messages, all of which comply with the behavior context. Once the event node is configured and properties and actions defined, the corresponding script can be generated by the visual scripting system, to be complied and executed as part of a user application.

  • Patent number: 10289096
    Abstract: A polishing machine is described in which a surface treatment tool is moved across the surface of a workpiece in accordance with a predefined tool-path, in order to carry out the desired treatment process. The tool-path is non-periodic and preferably pseudo-random. Various techniques are described for generating data representing the tool-path to be followed. A technique is also described for determining optimum control parameters used to control the polishing machine for a given tool-path. The surface treatment may be a shaping technique in which material is removed from the surface, or a technique for adding material to the surface of the workpiece, or a technique for modifying the surface or a region under the surface of the workpiece.

  • Publication number: 20190028414
    Abstract: An improved system and method for communication among clients using multiple messaging types are disclosed. In one example, a client includes at least one brew that interfaces with a module. The module encapsulates a transfer mechanism for sending and receiving messages using a particular message type. The client further includes at least one brewer or patron, but may include many brewers and/or patrons, each of which corresponds to at least one topic. An application using the client can send messages to other clients using a standardized interface provided by all brewers and may receive messages from other clients either from patrons using a standardized interface provided by all patrons or from the brew.
