  • Patent number: 8634938
    Abstract: A method for safely parameterizing an electrical device, wherein a parameter input by a user on a control unit is transmitted to the electrical device and stored therein with write protection, the stored parameter is transmitted back to the control unit and displayed at the control unit for confirmation by the user, and the user confirmation is transmitted to the electrical device. In accordance with the invention, the stored parameter is transmitted back together with the name of the parameter, with a code generated by the device and in a data format which cannot be processed by the control unit. The returned parameter, the name of the returned parameter and the code are displayed for the user on the control unit, and the confirmation is checked in the electrical device to determine whether the confirmation contains the code.

  • Patent number: 7420877
    Abstract: In a method for processing an echo profile generated by a pulse-echo ranging system, the echo profile is compared with a time-varying threshold function to identify valid echoes in those portions of the echo profile which exceed the TVT function. Based on the amplitude and/or area above the TVT function, each echo is rated and attributed a level of confidence. The echo with the highest level of confidence is selected as the echo of interest, and the level of confidence is reported. To provide an improved echo processing with increased accuracy in determining the confidence level of the selected echo of interest, it is furthermore determined whether the portion of the threshold function which timely corresponds to the selected echo of interest is part of a hump-shaped section of the threshold function. If so, said section is reshaped to reduced hump amplitude, and the confidence level of the echo of interest is redetermined based on the amplitude and/or area above the reshaped TVT function.

  • Publication number: 20050076701
    Abstract: A method and apparatus for calibrating a time-of-flight ranging or level measurement system coupled to a current loop. A first output current Is generated and the level of the first output current is measured. If the level is within an acceptable range, the level of the first output current is assigned to an internal current setting. A second output current is generated and the level of the second output current is measured. If the level is within an acceptable range, then the level of the second output current Is assigned to a second internal current setting. The first and second current settings are used to establish a range for controlling the current level in the current loop with the current level representing the process variable data, such as level measurement readings in a level measurement application.
