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 marker tip that engages with a display of a tablet device to produce mechanical input forces as a user engages the pen-stylus on the display of the tablet device and transmits the mechanical input forces;
- a writing shaft that receives the mechanical input forces transmitted from the marker tip;
- a force sensor that translates the mechanical input forces received from the writing shaft into electrical forces for operation by electronics in the pen-stylus;
- a writing shaft impact shock absorber that receives excess forces imparted to the pen-stylus to shield the force sensor from receiving the excess forces;
- and
- wherein the marker tip comprises deformable materials and wherein when a body of the pen-stylus receives a shearing force along angles at a front of the body of the pen-stylus that include the marker tip, the marker tip absorbs at least some of the shearing force by deforming its shape.
A pen-stylus, comprising:
- a removable marker tip that engages with a display on a tablet device as a user engages the pen-stylus on the display of the tablet device and transmits mechanical input forces, wherein the removable marker tip is designed for hand removal;
- a writing shaft that receives the mechanical input forces from the removable marker tip as the user engages the pen-stylus on the display of the tablet device;
- a force sensor that translates the mechanical input forces received from the writing shaft into electrical forces for operation by electronics in the pen-stylus;
- a writing shaft impact shock absorber that receives excess forces imparted to the pen-stylus to shield the force sensor from receiving the excess forces;
- and
- a writing shaft safety stop that prevents dislocation of the writing shaft when the user imparts excessive force in changing the removeable marker tip.
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 force sensor that translates the mechanical input forces received from the writing shaft into electrical forces for operation by electronics in the pen-stylus;
- a writing shaft impact shock absorber that receives excess forces imparted to the pen-stylus to shield the force sensor from receiving the excess forces;
- a rear erasure shaft, located at a rear end of the pen-stylus opposite to an end having the writing shaft, wherein the rear erasure shaft receives rear mechanical input forces as the user engages the rear end of the pen-stylus on the display of the tablet device;
- a rear force sensor that translates the rear mechanical input forces received from the rear erasure shaft into electrical forces for operation by electronics in the pen-stylus;
- and
- a rear shaft impact shock absorber that receives rear excess forces imparted to the pen-stylus to shield the rear force sensor from receiving the rear excess forces.
