  • Patent number: 8544447
    Abstract: One aspect is an electronic throttle control system including an electronic control unit configured to receive actuation signals indicative of a user action and to generate an actuation signal indicative of the user action. A throttle plate motor is configured to receive the actuation signal from the electronic control unit and to move a throttle plate in response thereto. A throttle position sensor is configured to sense the actual position of the throttle plate and to generate an actual position signal indicative of the throttle plate position. A throttle modifier is coupled between the throttle position sensor and the electronic control unit and configured to modify the actual position signal into a modified position signal, and to send the modified position signal to the electronic control unit.

  • Patent number: 8458000
    Abstract: A client-server based system for building and executing flows (i.e., interconnected systems of algorithms). The client allows a user to build a flow specification and send the flow specification to the server. The server assembles the flow from the flow spec and executes the flow. A flow may be configured to analyze the impact (e.g., the financial impact) of a number of uncertainties associated with a plurality of assets. Uncertainty variables are used to characterize the uncertainties associated with the assets. An uncertainty variable associated with one asset may be functionally dependent on an uncertainty variable associated with another asset.
