20090157280 | METHOD AND DEVICE FOR OPERATING AN INTERNAL COMBUSTION ENGINE - In a method and device for operating an internal combustion engine with an intake tract, a switching device for modifying an effective intake pipe length and/or an effective intake tract volume is arranged. By a dynamic intake tract model an estimated intake pipe pressure is determined. The dynamic model is adapted dependent on a trimming value. If a switching position modification is controlled, an estimated old position intake pipe pressure on the one hand is determined with the previous switching position and preventing of the adaptive trimming value adjustment and on the other hand an estimated new position intake pipe pressure is determined with the modified switching position and prevention of the adaptive trimming value adjustment and dependent on a correlation check of the estimated old position pressure and the estimated new position pressure with respect to the measured pressure an actual switching position of the switching device is identified. | 06-18-2009 |
20100299050 | METHOD AND APPARATUS FOR CONTROLLING AN INTERNAL COMBUSTION ENGINE - In a method for controlling an internal combustion engine comprising an intake pipe and a throttle valve that is arranged therein, the pressure in the intake pipe is regulated by modifying the opening angle of the throttle valve, and the desired pressure value is adjusted when the valve lift of the internal combustion engine changes. An apparatus for controlling an internal combustion engine has a mechanism for regulating the intake pipe pressure, the mechanism allowing the opening angle of the throttle valve to be influenced as a controlled variable. In addition, at least one device is provided for changing the valve lift of the internal combustion engine while a device is provided for adjusting the desired pressure value to the valve lift. | 11-25-2010 |

20130083894 | METHOD FOR CONTROLLING THE MOVEMENT OF AN X-RAY APPARATUS AND X-RAY SYSTEM - A method for controlling a movement of an x-ray apparatus is provided. The x-ray apparatus has a C-arm with an x-ray source and an x-ray detector disposed opposite one another, an actuator for positioning the C-arm relative to an examination region of an examination object supported on a support facility, a control facility for controlling the x-ray source and the x-ray detector and the actuator, and an operating facility with a display apparatus and an operating unit. The display apparatus displays an image representing a part of the examination object and a target location of the C-arm being determined as a function of an input at the operating unit. The target location has a target position and a target alignment of the C-arm. A controlled variable of the actuator is determined and supplied to the control facility for controlling the actuator. | 04-04-2013 |

20140163736 | COLLISION AVOIDANCE DURING CONTROLLED MOVEMENT OF IMAGE CAPTURING DEVICE AND MANIPULATABLE DEVICE MOVABLE ARMS - A system and method for movement control includes a controller coupled to a computer-assisted surgical device having a first movable arm coupled to a manipulatable device having a working end and a second movable arm coupled to an image capturing device. The controller is configured to receive first configurations for the first movable arm; receive second configurations for the second movable arm; receive a plurality of images of the working end from the image capturing device; determine a position and an orientation of the working end; determine a first movable arm position and trajectory for the first movable arm; determine a second movable arm position and trajectory for the second movable arm; determine whether motion of the movable arms will result in an undesirable relationship between the movable arms; and send a movement command to the first or second movable arm to avoid the undesirable relationship. | 06-12-2014 |
