Abstract
A key structure comprising a housing, a plunger extending from a top side of the housing and configured to be depressed and travel along a range of motion, a motion sensor system, and driving electronics, all contained within the housing, the sensor system configured to detect movement of the depressible plunger along the range of motion and generate corresponding travel data. One or more processors can be configured to determine a position of the plunger along the range of motion based on the travel data.
Claims22
A key structure comprising:
- a housing;
- a plunger extending from a top side of the housing and configured to be depressed and travel along a range of motion;
- and
- a motion sensor system integrated within the housing and configured to detect movement of the plunger along the range of motion and generate corresponding travel data,
- wherein one or more processors are configured to determine a position of the plunger along the range of motion based on the travel data.
A substrate with electrical traces configured to be integrated within a key structure for a keyboard, the substrate integrating thereon:
- a motion sensor system configured to detect movement of a target element coupled to a depressible plunger of the key structure along a range of motion and generate corresponding travel data;
- driving electronics configured to control the motion sensor system;
- and
- an interface circuit including multiple I/O pins operable to:
- receive a drive signal to drive the motion sensor system;
- receive electrical power to operate the motion sensor system;
- and
- provide an output signal including data corresponding to the motion sensor system.
