Abstract
In some embodiments, an apparatus for locking a computing device includes an actuator, a locking protrusion connected to a first portion of the computing device, a locking receptacle connected to a second portion of the computing device, a shape memory material (SMM) wire, and a force conditioner. The SMM wire has a first state and a second state and is movable between states by the actuator. The first state and the second state have first and second lengths, respectively. Moving from the first state to the second state applies a contraction force along a longitudinal direction of the SMM wire. The force conditioner is configured to apply a return force to the SMM wire that opposes the contraction face. The return force returns the SMM wire toward the first state while moving a maximum available force of the SMM wire to the second state of the SMM wire.
