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.
Viewing vibration in the frequency domain reveals the magnitude of vibration at different frequencies. âTotal Vibrationâ can be displayed with the TIR function on the MM190 Meter Module. Vibration is a time-based (periodic/cyclic) displacement of an object around a center static position.
