  • Patent number: 9411144
    Abstract: Various superimposing beam controls that can superimpose beams of light with different optical properties are described. In one aspect, a beam control receives a beam of light and outputs one or more beams. Each beam is output in a different polarization state and with different optical properties. Superimposing beam controls can be incorporated in fluorescence microscopy instruments to split a beam of excitation light into one or more beams of excitation light. Each beam of excitation light has a different polarization and is output with different optical properties so that each excitation beam can be used to execute a different microscopy technique.

  • Patent number: 9411324
    Abstract: The present invention provides a method of controlling the height of a looper in an inter-stand section of a hot strip mill that overcomes the problem of looper instability due to looper inertia without the need for the controller of upstream rollers to have a reduced gain. The inter-stand section of the hot strip mill comprises a pair of upstream rollers driven by a main motor and a looper driven by a looper motor. The method comprises the steps of: calculating a desired speed trim to be applied by the main motor; estimating the inertia of the looper; calculating a torque necessary to overcome the inertia of the looper from the speed trim, the estimated inertia of the looper and a sensitivity calculated from the geometry of the looper; and controlling the main motor to apply the speed trim to the upstream rollers and controlling the looper motor to apply the calculated torque to the looper.

  • Patent number: 9412082
    Abstract: A method and system for controlling demand events in a utility network with multiple customer sites. The value of a demand response parameter threshold for invoking a demand response event is calculated based on the number of available demand response events and the number of opportunities remaining to issue the available demand response events. This parameter represents the utility objectives for using the demand response program (e.g., cost savings, reliability, avoided costs). A current value of the demand response parameter is compared to the threshold value, and a determination is made whether or not to call a demand response event for the current opportunity, or to save the event for a future opportunity based upon this comparison.
