摘要： A sensing system is provided. A processing system drives a first subset of sensor electrodes with a sensing signal and receives corresponding resulting signals. The processing system also drives a second subset of the sensor electrodes with a reference signal and a third subset of the sensor electrodes with a guard signal. A rotatable electronic device includes a first coupling electrode and a second coupling electrode. The second coupling electrode couples with and receives the reference signal from the second subset of the sensor electrodes. The rotatable electronic device also includes a conductive region that rotates relative to the first coupling electrode and the second coupling electrode. The resulting signals are affected based on the position of the conductive region relative to the first coupling electrode when the first coupling electrode is coupled with the first subset of the sensor electrodes.

摘要： Sensor electrodes are coupled, in a first configuration, to input channels of a processing system. The sensor electrodes are used to acquire a measurement of current. In a second configuration that is different from the first configuration, the sensor electrodes are coupled to the input channels. The sensor electrodes in the second configuration are used to acquire a capacitive resulting signal. Positional information is determined using the current measurement and the capacitive resulting signal.

摘要： Input devices which include a capacitive force sensor, along with methods of making and using such, are provided. The input device includes a structural component having first and second substantially opposing sides, a plurality of sensor electrodes located on the first side of the structural component, the plurality of sensor electrodes configured to capacitively sense positional information associated with user input in a sensing region, a first capacitive electrode located on the second side of the structural component, the first capacitive electrode being configured to capacitively couple to a second capacitive electrode that is separated from the first capacitive electrode by a gas and moveable relative to the first capacitive electrode, and a biasing member configured to be physically coupled to the structural component such that a force associated with the user input causes a change in a separation distance between the first and second capacitive electrodes based on the force.

摘要： Devices and methods for capacitively sensing key cap position during the initial and latter stages of a keystroke. A key assembly includes a stationary key guide magnet, a movable key cap magnet, and a transmitter/receiver electrode pair. One or both of the electrodes underlies the key cap. The capacitance change between the electrodes during a keystroke includes the capacitance change between the key cap and the electrode pair, and the change in capacitance between the key cap and the key guide. Key cap position may thus be accurately detected throughout the entire keystroke.

摘要： Magnetically biased retracting key assemblies and keyboards are provided. A key assembly includes a touch surface for receiving a press input from a user and a planar-translation-effecting (PTE) mechanism configured to guide as the keycap moves from an un-pressed position toward a pressed position. The key assembly also includes a ready-return mechanism configured to magnetically biased the keycap in the un-pressed position, the ready-return mechanism including a slider mechanism positioned beneath the keycap and coupled to the PTE mechanism. When the press surface receives a press input the slider mechanism translates away from the magnet as the PTE mechanism guides the keycap from the un-pressed position toward the pressed position. In some embodiments, the PTE mechanism and the ready-return mechanism translate with respect to a chassis layer providing a key retraction feature for the key assembly or keyboard.
