  • Patent number: 11599243
    Abstract: A system for activating a screen cleaning mode for a user interface associated with a work machine includes a display screen associated with the user interface, the display screen being configured to display a control panel including a plurality of control icons for controlling one or more operations of the work machine. The system also includes a controller communicably coupled to the display screen. The controller is configured to receive a user input for activating the screen cleaning mode. The controller is also configured to switch the control panel to an inactive state. The control panel is switched to the inactive state based on a masking of the plurality of control icons. The controller is further configured to display a clean-up panel on the display screen. The clean-up panel includes a screen clean timer and a deactivation icon for deactivating the screen cleaning mode.

  • Patent number: 8950446
    Abstract: An electric generator set fuel control system is disclosed. The fuel control system includes an electric generator, a prime mover mechanically coupled to the generator, a first fuel tank, a fuel level sensor configured to generate a fuel level signal indicative of a fuel level in the first fuel tank, a fuel loading operator input device configured to generate a fuel loading signal, a fueling mode operator input device configured to generate a fueling mode signal, and a control module. The first fuel tank is configured to supply fuel to the prime mover, and selectively receive or supply fuel to a second fuel tank through a fuel pump. The control module is configured to generate a fuel transfer signal as a function of the fuel loading signal, the fueling mode signal, and the fuel level signal.

  • Patent number: 8841787
    Abstract: A method of controlling a plurality of gensets during a failsafe condition is provided. The method may include operating one or more of the gensets according to a modified isochronous control scheme, and operating a remainder of the gensets according an adaptive droop control scheme. The modified isochronous control scheme may include varying the frequency of each isochronous genset with respect to load for lower-range loads and upper-range loads, and maintaining the frequency of each isochronous genset at nominal frequencies for mid-range loads. The adaptive droop control scheme may include adjusting the frequency of each droop genset to match the frequency of the isochronous gensets, and varying the load of each droop genset with respect to frequency for lower-range loads and upper-range loads.
