  • Patent number: 11685258
    Abstract: A system and method for controlling a torque transfer clutch of a vehicle. A first data source indicates if the clutch is in AWD or 4×4 mode. An integrator system monitors energy transferred across the clutch. A temperature data source measures or calculates the clutch temperature. In a first case, the integrator accumulates data of the energy across the clutch during a monitoring period that is compared to a maximum accumulated energy value and initiates a powertrain torque dependent transfer point learn routine. In a second case, the controller responds to energy accumulator cycle data in a single monitoring cycle that is compared to a maximum cycle data value. In a third case, the controller responds to clutch temperature data and compares the temperature data to a maximum temperature value. The second and third cases initiate a non-powertrain torque dependent transfer point learn routine.

  • Patent number: 9033450
    Abstract: A printer having an internal electrical power supply is disclosed herein. A method for controlling power consumption in the printer includes receiving an image to be printed, calculating an estimated temperature of the printer, and controlling a speed of the printer to control the power consumption to keep a temperature of the printer below a predetermined maximum temperature in response to the estimated temperature.

  • Patent number: 8899717
    Abstract: A printing system including a print mechanism to print on a print medium; and a control unit coupled to the print mechanism. The control unit is to determine a page speed for the print medium based on a power budget value of a power supply and to cause the print mechanism to move the print medium through the printing system at the determined page speed.
