Abstract
Force measuring systems for electronic pens, styli, or other products may include structure for changing a direction or location of application of a force (e.g., a force transmitted via pen or stylus contact with a writing surface) from a first direction or location to a second direction or location. In this manner, a sensor portion of the force measuring system may be reoriented in a direction such that it is not normal to the direction of the force. This feature may help make electronic pens or styli (or other products) thinner and dimensioned more consistent with their non-electronic counterparts. Various structures for changing the direction or location of application of the force are described.
