Abstract
An input device comprising: a printed circuit board (PCB) comprising non-linear circuitry; resistive circuitry including a force-sensitive resistor (FSR) coupled to the PCB in parallel with the non-linear circuitry; and a hinge coupled to the PCB and the FSR configured to strain the FSR in response to a force applied to a tip of the input device. A stylus comprising: a housing; and stylus circuitry at least partially positioned within the housing, wherein the stylus circuitry comprises: body circuitry; a front tip interface; and front tip stylus circuitry positioned between and electrically coupled to the body circuitry and the front tip interface, wherein the front tip stylus circuitry comprises non-linear circuitry in parallel with physical interaction characteristic (PIC) circuitry; wherein the front tip stylus circuitry is operative to provide a non-linear load between the body circuitry and the front tip interface when the stylus is stimulated by an external stimulation; wherein the non-linear load is operative to provide a stylus electric field that is detectable by an electronic device when the front tip interface of the stylus is positioned adjacent an input surface of the …
