Abstract: A digital emulation of an analog device with tolerance modeling is disclosed. In operation, a model of an analog circuit is provided. The model includes the location of each individual element in the analog circuit. The model also includes a working value for each individual element as well as a tolerance range for each individual element. A randomized working value is then generated for one or more of each individual element based on the tolerance range and the working value. A digital emulation of the analog circuit is performed. The digital emulation uses the randomized working value for one or more of the each individual element and the working value for any remaining of each individual element. The digital emulation is then provided to a user for use in a digital environment.

Abstract: The invention relates to a clamping device on a vibrator, by means of which a pipe (11,12) is rammed into the ground. According to the invention, the clamping device is designed as a pipe collet chuck having at least two partial areas radially outwardly displaceable by means of one or more expanding elements (14, 15), wherein the length of the pipe collet chuck corresponds sub-stantially to the length of the pipe or pipe part to be rammed. The invention further relates to a me-thod for clamping the pipe using the clamping device indicated, which is inserted into the pipe along the entire length of the pipe, before the expanding elements of the pipe collet chuck are actuated for radially expanding for frictionally or positively contacting the internal wall of the pipe to be clamped.

Abstract: A system for spectrally filtering light is provided. The system includes a variable wavelength selector for selecting a wavelength from a light source and a tunable interference filter for filtering light from the variable wavelength selector. The interference filter may be synchronously tunable to the output of the variable wavelength selector.
