  • Patent number: 11315186
    Abstract: Methods and apparatuses are described for automatic execution of subscription-based financial instrument trading strategies in real-time. A server receives a request to deploy a trading strategy with trading strategy parameters. The server determines that a trading strategy has already been created for other users based upon the parameters. The server generates a subscription to the trading strategy, which comprises indicators needed to deploy the trading strategy. The server identifies at least one indicator that has already been calculated and calculates any of the indicators that have not already been calculated. The server deploys the trading strategy using the identified and calculated indicators.

  • Patent number: 10684160
    Abstract: Devices are provided to measure the mass inertia of moving surfaces (e.g., aircraft components). In certain embodiments, the devices will include a support frame formed by first and second structural frame members which form a space for positioning of a moving surface to be measured for mass inertia. A pivot joint assembly is supported by an upper portion of the first structural frame member while a distance alignment device is arranged at a lower portion of the support frame. The second structural frame member including an extension and a dynamometer supported operatively by the extension. The first structural frame member includes a comparator clock at a lower portion thereof.

  • Publication number: 20140244211
    Abstract: A method for measuring mass inertia of moving surfaces, comprising the steps of: (a) Alignment of the center of gravity of an assembly (90) formed by the moving surface (50) and a support device (70) fastened to at least two joints (31, 32) in a rest position, this alignment comprising a reading in a comparing clock (40) and driving of an adjusting element arranged in the support device (70) for obtainment of a predetermined value in the comparing clock (40); (b) Measurement of the static moment of assembly (Mstatic) in an intermediate position through a dynamometer (60); (c) Measurement of the oscillation period of assembly (T) in a pendulum position through an accelerometer arranged in the support device (70) and (d) Reading of the static moment of assembly (Mstatic) and that of oscillation period of assembly (T) and obtainment of the inertial moment of the moving surface (Ihhsup)—An equipment (10) for measurement of mass inertia of moving surfaces, is further described, comprising: a structure (20) formed
