Abstract: A changing table has a changing surface on which an individual can lie to be changed or washed. The changing surface is formed from a sheet of semi-rigid material having a longitudinal center axis and having also, parallel to the center axis, first and second edges occupying nominal rest positions with respect to each other when there is no load on the surface, the said edges being fixed to first and second longitudinal members, the sheet and longitudinal members forming together a support system having for the first 10 mm of extension between the said center line and the said nominal rest position of the said first edge and between the said center line and the said nominal rest position of the said second edge an average spring rate in extension of more than 300 N/mm and the said semi-rigid sheet having a torsion coefficient of more than 10 Nm/radian.

Abstract: A method of classifying a signal waveform under test for appropriate numerical measurement includes acquiring waveform data indicative of the signal waveform under test, analyzing the waveform data, determining a signal waveform type from the analyzed waveform data, and activating an appropriate numerical measurement of the signal waveform under test based upon the determined signal waveform type. There is also provided a test and measurement instrument configured to carry out any of the disclosed methods.
