20090127061 | METHOD OF FEEDING A CLUTCH CYLINDER OF A HYDRAULICALLY ACTUATED CLUTCH SYSTEM - A method of feeding a clutch cylinder in a hydraulically actuated clutch system in a motor vehicle and a respective hydraulically actuated clutch system are suggested. The clutch system comprises at least one clutch that can be closed by filling the clutch cylinder; and a hydraulic system that provides a system pressure and has a clutch control valve having an inlet and an outlet. A system pressure is applied at the inlet of the control valve; the clutch pressure for actuating the clutch is provided at the outlet; and the system pressure is decreased pressure prior to and during the filling of the clutch cylinder. The decreased system pressure allows a high volume flow and therefore a fast filling of the clutch cylinder without establishing a premature torque transmitting capacity in the clutch. | 05-21-2009 |

20120144940 | AUTOMATED TRANSMISSION AND METHOD FOR OPERATING AN AUTOMATED TRANSMISSION - An automated transmission comprises a hydraulic control device and one or more hydraulically actuated gear units. The hydraulic control device comprises a control unit for setting actuating pressures on the gear units; a base pressure control valve for adjusting a hydraulic base pressure of the hydraulic control device; and a device for controlling the base pressure control valve dependent on the actuating pressures. The automated transmission further comprises a device for switching through an actuating hydraulic pressure to the base pressure control valve. A method comprises the method steps of adjusting a hydraulic base pressure at the hydraulic control device; adjusting actuating pressures for actuating one or more transmission units; switching through one of the actuating pressures to the base pressure control valve; and adjusting the hydraulic base pressure by one of the actuating pressures. | 06-14-2012 |

20160036454 | ALL-DIGITAL PHASE-LOCKED LOOP (ADPLL) WITH REDUCED SETTLING TIME - Settling time may be reduced or eliminated for a phase-locked loop (ADPLL). An oscillator model provides proper settings that are applied to compensate both the frequency response and the phase response. A hardware device may include a Digital Controlled Oscillator (DCO); and a DCO model device with a processor, wherein the processor is configured to calculate a frequency for the DCO by searching for the frequency based upon operational parameters of the DCO, compare the calculated frequency to a measured frequency, and compensate, based upon the comparison, an ADPLL to decrease a settling time. | 02-04-2016 |
