  • Engine cooling system and method for engine cooling
    Patent number: 8931440
    Abstract: Various methods and systems are provided for adjusting the speed of a cooling system fan. In one example, a method includes adjusting a speed of a cooling system fan based on ambient temperature, engine output, and a desired engine temperature.
    Type: Grant
    Filed: July 26, 2012
    Date of Patent: January 13, 2015
    Assignee: General Electric Company
    Inventors: Johan Fredrick Mahrs, Kyle E. Schmidt, John Y. Zhang
  • Driver that presents context sensitive information about device features
    Patent number: 8670161
    Abstract: A printer driver enables a user to determine whether the features that are required to print a specified job are available to a selected network printer. The printer driver queries the selected printer to acquire the current status and other relevant information for each feature that is required to print the job, then provides the results of the query at a user interface. Accordingly, if any of the required features are unavailable to the selected printer, the user can print the job using another printer or take some other appropriate action.

  • Protocol allowing modification of device attribute availability on a print network
    Patent number: 8064087
    Abstract: A method to modify the availability of one or more attributes within a print network. One or more devices are interrogated to determine associated attributes. A first set of attribute combinations that cause device failure is determined and placed in an unsupported bank for each device. A second set of attribute combinations that do not cause device failure are determined and placed in a supported bank for each device. Access to the first set of attribute combinations is disabled and access to the second set of attribute combinations is enabled.

  • Protocol allowing a document management system to communicate inter-attribute constraints to its clients
    Patent number: 7944572
    Abstract: A system facilitates communication between a control component and a plurality of processing components. One or more processing components performs one or more tasks, each processing component has at least one attribute associated therewith. One or more attribute banks are associated with each of the one or more processing components, wherein each attribute bank stores the at least one attribute. A control component initiates the one or more tasks for each processing component. A universal driver facilitates communication between the one or more processing components and the control component. The driver includes an interrogation component that queries the one or more processing components to receive the at least one attribute associated with each processing component. A constraint evaluator determines combinations of attributes that are supported and unsupported for each of the one or more processing components.
