  • Publication number: 20220096954
    Abstract: A method for control and optimization of a stillage evaporation process, the method providing monitoring a conductivity of a stillage stream to obtain a conductivity value; correlating the conductivity value to a dry solids percentage (% DS) present in a stillage evaporator system to obtain an evaporator solids profile; and utilizing the evaporator solids profile to obtain a mass-balance solids profile of a stillage evaporator system to control and optimize a dry solids evaporation process.

  • Patent number: 10025926
    Abstract: A method for analyzing side-channel leakage of an application running on a device including loading the application on a system comprising a device simulator, wherein the application is configured to accept public inputs and secret inputs and selecting a set of public inputs. The method includes, for each public input in the set of public inputs, executing the application on the system comprising the device simulator based on a respective public input and a first value for a secret input and extracting first intermediate values for the simulated device, and executing the application on the system based on the respective public input and a second value for the secret input and extracting second intermediate values for the simulated device. The method includes determining an amount of dependency of a location of the simulated device on the secret input based on a plurality of the first and second intermediate values.

  • Publication number: 20150078866
    Abstract: The invention relates to an unload access system for an unit load device, comprising a framework, the framework delimiting a cargo space arranged on a ground load deck and the framework comprising an unload deck for unloading shipments out of the unit load device, whereby the unload deck is arranged distant above the ground load deck and extends in an offset plane adjacent to the cargo space, the unload deck comprises a movable platform, and the platform extends coplanar with the unload deck and is movable between a retracted position and a maximum extracted position, whereby in the maximum extracted position the platform overlaps at least partly the cargo space by extending into the cargo space and in the retracted position the platform does not overlap the cargo space.

  • Patent number: 8379072
    Abstract: The most preferred embodiments of the present invention are configured to allow a foreign language interpreter to remotely monitor, control, and interpret various legal proceedings for one or more remote locations, such as courtrooms. The interpreter will use a computer-based system to monitor and control the audio-video functions and communications that take place in one or more remote locations and to pass audio and/or video signals to and from the interpreter and the remote locations, including the people in the remote location that need interpretation services. This system allows the interpreter to monitor facial characteristics of the speakers, route the audio to isolated headsets when interpreting into the foreign language, route the audio to sound reinforcement speakers when interpreting from the foreign language, and interpret a “private” conversation between multiple parties speaking different languages.

  • Patent number: 8057192
    Abstract: A condensate pump includes a condensate reservoir, a liquid level float sensor operable to sense a liquid level within the condensate reservoir, and a pressure/vent valve including a pressure source, a pressure vent, and a primary piston slidably supported in a primary cylinder and sliding in the primary cylinder responsive to the liquid level sensor. A secondary piston is slidably supported in a secondary cylinder and moves responsive to a movement of the primary piston between a first secondary-piston position wherein the pressure source is in communication with a gas space of the condensate reservoir and the pressure vent is isolated from the gas space, and a second secondary-piston position wherein the pressure source is isolated from the gas space and the pressure vent is in communication with the gas space. An aperture in the primary piston and passages may also be provided to prevent build-up of gas pressures and maintain pressures in preselected regions within the pump at atmospheric pressures.
