Abstract: A compression fabric to which is attached a pocket into which is fitted padding that has a base and a plurality of half cylindrical shape portions that are arranged parallel to each other and spaced apart by respective gaps and that project outward from the base. The compression fabric may be a short or long sleeve of a sports jersey or an arm band. The padding is thin enough to be trimmed with scissors to suit the length of the upper arm of the wearer as desired.

Abstract: Systems and methods are described for transmitting a waveform having a controllable attenuation and propagation velocity. An exemplary method comprises: generating an exponential waveform, the exponential waveform (a) being characterized by the equation Vin=De?ASD[x?vSDt], where D is a magnitude, Vin is a voltage, t is time, ASD is an attenuation coefficient, and vSD is a propagation velocity; and (b) being truncated at a maximum value. An exemplary apparatus comprises: an exponential waveform generator; an input recorder coupled to an output of the exponential waveform generator; a transmission line under test coupled to the output of the exponential waveform generator; an output recorder coupled to the transmission line under test; an additional transmission line coupled to the transmission line under test; and a termination impedance coupled to the additional transmission line and to a ground.
