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.
Heat generated by living organisms may also be measured by direct calorimetry, in which the entire organism is placed inside the calorimeter for the measurement. A widely used modern instrument is the differential scanning calorimeter, a device which allows thermal data to be obtained on small amounts of material.
