Abstract (en)
[origin: GB2325303A] The invention is based upon impact vibrational input and corresponding waveform generation by a piezo-electric cable transducer. Analysis of the waveform output on a frequency or time-base shift with respect to pressure provides a basis for numerical pressure determination based on identification of dominant peaks. Repeated constant level impacts by a solenoid-operated hammer device during inflation enables monitoring of the dominant peak and thus inflation pressure.
