FORCE-DETECTING INPUT STRUCTURE
First Claim
Patent Images
1. An electronic device, comprising:
- a housing;
a collar, coupled to the housing, comprising;
a moveable conductor;
a conductive element; and
a separation defined between the moveable conductor and the conductive element; and
an input structure extending from the collar;
wherein movement of the input structure changes a capacitance between the moveable conductor and the conductive element.

Abstract
An input mechanism, such as a crown, detects amounts of applied force. In various examples, an assembly including an input mechanism has an enclosure; a stem coupled to the enclosure such that the stem is rotatable, translatable, and transversely moveable with respect to the enclosure; a sensor, coupled between the stem and the housing, to which force is transferred when the stem moves with respect to the housing; and a processing unit coupled to the sensor. The processing unit is operable to determine a measurement of the force, based on a signal from the sensor.
