Aspects of the invention include a computer peripheral device comprising an input element that operates based on a performance characteristic, an electropermanent magnet (EPM) assembly including a permanent magnet configured to generate a magnetic field and a magnetizing assembly configured to set an intensity of the magnetic field generated by the permanent magnet, and a magnetorheological (MR) material coupled to the input element. The MR material has a viscosity that changes based on the magnetic field and affects the performance characteristic of the input element.

A surgical footswitch for controlling a surgical instrument. The surgical footswitch includes a base. A treadle is rotatably coupled to the base to operate the surgical instrument. A foot guard is also rotatably coupled to the base. A blocking portion of the foot guard is configured to prevent physical access to the treadle in a lateral direction in a first position and permit access to the treadle in a lateral direction in a second position. A floor engagement portion of the foot guard engages a floor surface when the blocking portion is in the first position. The floor engagement portion is spaced from the floor surface when the blocking portion is in the second position. The floor engagement portion permits physical access to the treadle in a longitudinal direction when the blocking portion is in both the first position and the second position.
