Abstract: An indicator arm apparatus includes a mount unit configured to be secured to a vehicle, a first pivotal arm assembly having a first indicator and first hinge unit configured to move the first indicator from a retracted position to a deployed position, a second pivotal arm assembly having a second indicator and second hinge unit configured to move the second indicator from a stored position to an extended position, a first drive unit operably linked to at least one of the pivotal arm assemblies to move the respective indicator between respective positions, and a control unit in operable communication with the first drive unit to provide signals to selectively move at least one indicator. Each hinge unit comprises a pivotally affixed portion that is also affixed to an indicator to pivot the indicator between respective positions.

Abstract: Systems and methods are provided for filtering and/or creating Points-of-Interest (POIs). In one embodiment, a list of POIs is obtained and then filtered based on crowd data related to the list of POIs to provide a filtered list of POIs. In another embodiment, one or more crowd-sourced POIs are created based on one or more crowds relevant to a corresponding bounding region for POI creation.

Abstract: Illustrative embodiments include methods, and corresponding systems, that leverage cryptocurrency and blockchain technology to provide user-controlled, secure and rapid currency conversion and currency exchange between parties. Illustrative embodiments convert funds denominated in a source currency to a cryptocurrency, and then convert the cryptocurrency to funds denominated in a destination currency.

Abstract: The present invention relates to a method for providing an interoperable digital rights management system for content data on a client based on synchronization technology, the method comprising the steps of: —receiving of a selection of content data from the, client, —generating of an XML file having a defined DTD format, the XML file comprising license information and a locator for the content data, —sending of the XML file to the client, synchronizing any license status relates data produced on the client back to the server.

Abstract: A computer implemented method of delegating activities in a service oriented architecture of distributed computing systems. An activity specification is defined. The activity specification contains a set of service invocations. The activity specification is transformed into continuation passing style to form an activity. The activity is then executed using an activity execution engine.

Abstract: A user provides signature attributes to a computer system for generating a signature, such as content directories, a signature accuracy level, and whether an existing signature database exists. The computer system generates a signature and the user tests the signature against a test file system. Based on the test results, the user may refine the signature using a different file system or a different content installation. In one embodiment, a user may generate a parent signature from existing “child” signatures that correspond to different versions of particular content. For example, a user may wish to generate a “Program” parent signature using children signatures “program v.0,” “program v.1,” and “program v.2.” When the user is satisfied with the signature, the user may use the signature to detect content that is located in a computer device's file system.

Abstract: A test apparatus for the measurement of expansion and/or shrinkage of a cement test sample during curing under pressure and temperature conditions that simulate downhole oil well conditions isolates the test sample from a first fixed volume of incompressible pressurized liquid using a flexible barrier that forms a wall of a first chamber in a pressure vessel assembly. The first chamber is sealed by a movable piston. A second pressurizing medium is contained in a second chamber on the opposite side of the piston, and is in fluid communication with a pump, whereby the piston is pressure-balanced between the first and the second medium. The piston moves in a bore of the vessel assembly in response to changes in the volume of the test sample during curing and the amount of linear movement of the piston is detected by a sensor system that measures, correlates and transmits any change in the position of the piston as a change in the sample volume for display and recording.
