Abstract
An active stylus includes a stylus tip assembly and an elongate housing enclosing a portion of the stylus tip assembly. A winged bracket mounted within the elongate housing and affixed to a tip-distal end of the stylus tip assembly is configured to flex in response to pressure applied to the stylus tip assembly. A strain gauge disposed along the winged bracket is configured to measure strain along the winged bracket caused by pressure applied to the tip assembly.

An active stylus, comprising:
- a stylus tip assembly;
- an elongate housing enclosing a portion of the stylus tip assembly;
- a winged bracket mounted within the elongate housing and affixed to a tip-distal end of the stylus tip assembly, the winged bracket configured to flex in response to pressure applied to the stylus tip assembly;
- and
- a strain gauge disposed along the winged bracket, the strain gauge configured to measure strain along the winged bracket caused by pressure applied to the stylus tip assembly.
An active stylus, comprising:
- a stylus tip;
- a tip holder assembly that encloses a portion of the stylus tip;
- an elongate housing defining a window through which the stylus tip extends outside the elongate housing;
- a winged bracket mounted within the elongate housing and attached to a tip-distal end of the tip holder assembly, the winged bracket configured to flex in response to pressure applied to the stylus tip;
- and
- a strain gauge disposed along the winged bracket, the strain gauge configured to measure strain along the winged bracket caused by pressure applied to the stylus tip.
An active stylus, comprising:
- a stylus tip;
- a tip holder assembly that encloses a portion of the stylus tip;
- an elongate housing defining a window through which the stylus tip extends outside the elongate housing;
- a winged bracket mounted within the elongate housing and attached to a tip-distal end of the tip holder assembly, the winged bracket including two supporting wings that extend in opposite directions and attach to a supporting shell within the elongate housing, the two supporting wings configured to flex in response to pressure applied to the stylus tip;
- and
- a strain gauge disposed along the two supporting wings, the strain gauge configured to measure strain along the two supporting wings caused by pressure applied to the stylus tip.
