In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the pollutants.

You could ( for example ) have the person move the finger forwards and backwards-measure the movement ( using some non-contact method involving cameras or lasers or something ) and detect the change in the persons'center of gravity as this happens.

If you want to double check, you could email the Billy Rose Theatre Collection at the New York Public Library for the Performing Arts, or check with a librarian there during working hours via the contact methods on this webpage : http : / / ask . nypl . org /.

One example is the Tonopen that can be used on children and for those who cannot place their chins on the slit-lamp . �The non-contact methods can be utilized when patients have active corneal infections or corneal epithelial defects . �The GAT is affected by the variability in central corneal thickness affecting the final IOP result.

When the temperature of a surface is accurately known ( e . g . by measuring with a contact thermometer ), then the sensor's emissivity setting can be adjusted until the temperature measurement by the IR method matches the measured temperature by the contact method; the emissivity setting will indicate the emissivity of the surface, which can be taken into account for later measurements.
