Abstract
Embodiments of the invention provide a plurality of safety features for a pen-stylus. The pen-stylus may comprise a writing shaft that receives mechanical input forces as a user engages the pen-stylus on a display of a tablet device, a force sensor that translates mechanical input forces received from the writing shaft into electrical ones for operation by electronics in the pen-stylus; and a writing shaft impact shock absorber that receives heavy forces imparted to the pen-stylus to shield the force sensor from receiving such heavy forces. The heavy forces impacting the pen-stylus may arise from the pen-stylus being dropped onto a hard surface.
Claims20
A pen-stylus, comprising:
- a writing shaft that receives mechanical input forces as a user engages the pen-stylus on a display of a tablet device;
- a bottom bracket that prevents the writing shaft from rotating about a center axis that runs from a proximal end to a distal end of the pen-stylus;
- a force sensor that translates the mechanical input forces received from the writing shaft into electrical ones for operation by electronics in the pen-stylus;
- and
- a writing shaft impact shock absorber, disposed between the writing shaft and the force sensor, that receives excess forces imparted to the pen-stylus to shield the force sensor from receiving the excess forces.
