Abstract

1525259 Writing pen pressure transducers for determining stress R M SMITH 3 Oct 1975 40525/75 Heading G1N A ball point pen incorporates a pressure capsule and produces a frequency trace when writing a standard phrase or sentence. A reference trace is obtained under normal circumstances, when the writer is not under stress, and compared with subsequent frequency traces obtained under different conditions. The frequency signal is radio coupled to a receiver and recorded on a chart running at a known speed whereby the chart indicates both pressure and speed of writing.
