You'd think the iPhone panopticon would make two-party consent laws look antiquated. Yet some states are enforcing them more vigorously than ever. In Illinois, for example, civil-liberties advocates are challenging a law that says you can be thrown in jail for 15 years for recording a conversation with a police officer.
The use of weighting networks gives a single number as a measure of vibration exposure and is expressed as the frequency-weighted vibration exposure in metres per second squared (m/s2), units of acceleration. Vibration meters equipped with accelerometers can be used for instantaneous vibration measurement.
There is a common misconception that measuring displacement using an accelerometer is not. possible or can lead to erroneous information. In reality, accelerometers have long been used to. measure displacement. However, it is important to understand that displacement measured with. an accelerometer is not the same displacement measured with shaft riders or eddy current style. vibration transducers. Eddy current probes are precisely thru-hole mounted into a mechanical casing and measure two. very important shaft parameters.
