20130188171 | METHOD FOR DETERMINING THE PH VALUE OF A LIQUID AND SENSOR ARRANGEMENT - A system and method for determining the pH value of a liquid. The system and method excite the liquid molecules in the liquid by light with a predetermined wavelength and an intensity component, transmitted through the liquid in a predetermined wavelength range, of the light used for excitation is captured. This intensity component is used to produce a wavelength/intensity absorption characteristic and this absorption characteristic is related to a reference absorption characteristic associated with a specific pH value of the liquid. The system and method thus can be used to obtain drinking water from a fuel for aircraft. | 07-25-2013 |

20110285884 | Circuit for Processing a Time-discrete Analog Signal and Image Sensor - A circuit for processing an analog signal having a time sequence of discrete signal levels, each of which lies in a time interval and represents an information-bearing segment of the interval while the rest of the time interval is a non-information-bearing segment, comprises a transistor in emitter-follower or source-follower configuration, a high emitter or source resistance or, instead, a high-ohm constant current source, and a device for applying a voltage supply, as well as a switch which is connected between the emitter and a reference potential to prevent a current from flowing via the high-ohm resistance or the high-ohm voltage source for charge reversal of an output capacitance of the circuit in one direction, whereas for charge reversal in the other direction the dynamic current boosting effect of the transistor is exploited. This results in a fast emitter-follower or source-follower circuit which is particularly suitable as the output stage for image sensors. | 11-24-2011 |

20120239272 | Method for testing the fuel quantity balance in a common rail system, corresponding engine control system, and corresponding diagnosti device - In a common rail system having two electrically controlled actuating elements, e.g., a metering unit at the input side of a high-pressure pump and a pressure regulating valve on the common rail, different fuel delivery quantities are able to be set in the common rail system while the vehicle is stationary, independent of the current engine load, by controlling operating points via one of the actuating elements and subsequently regulating the other actuating element. Control currents of the actuating elements correspond to the operating points. These control currents, or differences of control currents, are compared to target values to enable an evaluation of the common rail system. | 09-20-2012 |
