Abstract: Pulley assemblies and associated methods are disclosed. An example pulley assembly may include a first pulley and a second pulley laterally movable relative to the first pulley. The first pulley and the second pulley provide for different drive ratios. The second pulley is movable from a first position in which the second pulley is laterally offset from the first pulley and a second position in which the second pulley is laterally aligned with the first pulley. An endless drive components, such as an endless belt, maintains a constant position whether the endless drive component is engaged with the first pulley or the second pulley located in the second position.

Abstract: A method and device for monitoring thermal stress in a user is described. The device is designed to include a material having specific thermodynamic properties and physical dimensions defined as a function of those thermodynamic properties. A system for thermal stress monitoring including a thermal stress monitoring device configured within a garment is also described.
