Figure 7

Lossless compression. File-size reductions (FSR) as functions of contraction level (%MVC). a) Lossless ZIP compression results are presented for the longitudinal (filled circles) and transversal (empty circles) arrangements of upper trapezius signals, and for the longitudinal (filled diamonds) and transversal (empty diamonds) arrangements of medial gastrocnemius signals. b) Lossless JPEG compression results are presented for single-differential upper trapezius signals before (filled circles) and after (empty circles) time differentiation, and for single-differential medial gastrocnemius signals before (filled diamonds) and after (empty diamonds) time differentiation.
