A waveform analysis device 200 comprises: a sensor unit 300 for detecting a physical phenomenon; a discrete Fourier transform unit 208 for performing a discrete Fourier transform of a detection signal transmitted from the sensor unit 203; a later-stage weighting unit 209 for setting amplitude values at each frequency generated by the discrete Fourier transform unit 208 that exceed a prescribed upper-limit value to said prescribed upper-limit value; and an accumulation unit 210 for adding the amplitude values at each frequency weighted by the later-stage weighting unit 209. An operator console 100 sets the prescribed upper-limit value in the waveform analysis device 200.

There is provided a system for determining multiple baselines for detecting events in a conduit. The system comprises an optical fiber interrogator for interrogating optical fiber; and one or more processors communicative with the optical fiber interrogator and memory having stored thereon computer program code configured, when executed by the one or more processors, to cause the one or more processors to perform a method. The method comprises, for each of multiple channels of the conduit, each channel comprising a portion of the conduit: obtaining phase data for the channel, the phase data being obtained by causing the optical fiber interrogator to interrogate optical fiber positioned alongside the conduit; and determining one or more baselines from the phase data. As a result, events in the conduit may be detected with fewer false positives.

[Problem]

A method for offset calibration of a rotation rate sensor signal of a rotation rate sensor. In a first step, an ascertainment is made that the rotation rate sensor is in an idle state. In a second step, after the first step, a filter parameter is determined as a function of the measured rotation rate sensor values, measured in the idle state, of the rotation rate sensor. In a third step, after the second step, a filtered measured rotation rate sensor value is determined with the aid of the filter parameter. An offset is determined with the aid of the filtered measured rotation rate sensor value.

A device for contactlessly determining a position of a pedal in a vehicle, having at least a magnet and a sensor, wherein the magnet produces a magnetic field that varies with the position of the pedal and detected by the sensor. The sensor has an output for providing at least one sensor signal. A first and a second position range are defined, wherein each position range includes positions of the magnet with respect to the sensor. The processor generates an output signal from the at least one sensor signal. The output signal takes on values that are unambiguously associated with a position of the magnet relative to the sensor in the first position range, and takes on a constant value that is independent of the position of the magnet relative to the sensor in the second position range.

According to examples, an apparatus may include a processor that may receive an environmental condition detected at an electronic device and may determine whether the received environmental condition is outside of a predefined threshold range for the electronic device. The processor may, based on a determination that the received environmental condition is outside of the predefined threshold range for the electronic device, generate a notification item in a configuration page of the electronic device indicating that the electronic device has operated in an environmental condition that is outside of the predefined threshold range for the electronic device. The processor may also store the generated notification item in the configuration page of the electronic device, in which a service agent of the electronic device is to access the notification item in the configuration page stored in the electronic device.
