| 20080309547 | Method and Apparatus for Optimizing Emission in Pulse Echo Methods - Emission values of pulse echo methods known to this point in time, especially those, which are used in industrial measurements technology for fill level measurements, frequently reach the allowable limit values. To avoid possible radio permitting of such measuring devices, the invention provides a method and a circuit for optimizing emission of broadband transmission pulses of a pulse echo method, wherein the transmission pulses are transmitted with a pre-selected pulse repetition frequency. The method and circuit of the invention provide that the polarity of a pulse is switched with each cycle of the pulse repetition frequency, depending on a random sequence, or that individual pulses are suppressed with each cycle of the pulse repetition frequency, depending on a random sequence. | 12-18-2008 |
| 20090212997 | Method for measuring a distance running time - A method for ascertaining the distance on the basis of the travel-time of high-frequency measuring signals, wherein at least one periodic, pulsed, transmission signal having a pulse repetition frequency is transmitted and at least one reflected measuring signal is received. The transmission signal and the reflected measuring signal are transformed by means of a sampling signal produced with a sampling frequency into a time-expanded, intermediate-frequency signal having an intermediate-frequency. The time-expanded, intermediate-frequency signal is filtered by means of at least one filter and a filtered, intermediate-frequency signal is produced, wherein the intermediate-frequency is matched to a limit frequency and/or a center frequency of the filter. The matching of the filter to the intermediate-frequency of the time-expanded measuring signal results, reducing production costs. | 08-27-2009 |

| 20100301878 | APPARATUS FOR ASCERTAINING AND/OR MONITORING AT LEAST ONE FILL LEVEL OF AT LEAST ONE MEDIUM IN A CONTAINER ACCORDING TO A TRAVEL-TIME MEASURING METHOD AND/OR A CAPACITIVE MEASURING METHOD - An apparatus for ascertaining and/or monitoring at least one fill-level of at least one medium in a container according to a travel-time measuring method and/or a capacitive measuring method by means of at least one measuring probe. The apparatus comprises a capacitive measurement circuit, a time-domain reflectometer measurement circuit, and a control/evaluation unit. There invention results from the provision of a diplexer, which sends the low-frequency measurement signal and the high-frequency, electromagnetic measurement signal to the measuring probe and effects a signal separation of the high-frequency, electromagnetic measurement signal into the first signal path of the time-domain reflectometer measurement circuit and the low-frequency measurement signal into the second signal path of the capacitive measurement circuit. | 12-02-2010 |
