Abstract: A sensor system (200) that includes a flexible substrate (502), a plurality of first sensing lines (504-X), and a plurality of second sensing lines (510-X) is disclosed. The flexible substrate has a first surface (506) and an opposite, second surface (508). The plurality of first sensing lines are substantially parallel and are spaced apart in the lateral direction, wherein each of the plurality of first sensing lines is coupled to the first surface of the flexible substrate. At least a portion of each of the plurality of second sensing lines is exposed on the first surface and at least a second portion of each of the plurality of second sensing lines is exposed on the second surface. The sensor system further detects, based on signals from the plurality of first sensing lines and the plurality of second sensing lines, that a user has made a swipe gesture along the first surface in the longitudinal direction.

Abstract: A method includes one or more processors of an electronic device receiving signals from multiple sensors located along an edge of the device. The signals are received in response to external contact being provided to the edge of the device. At least one processor determines a distribution of forces applied to the sensors based on the input signals. Based on the determined distribution of forces, the processor determines: i) a location of the external contact that is offset from a location of each of the multiple sensors, and ii) a magnitude of the force of the external contact. The processor detects whether sensing criteria has been satisfied based on an analysis of: i) the location of the external contact and ii) the magnitude of the force of the external contact. Responsive to detecting that sensing criteria has been satisfied, the processor executes a user input action.

Abstract: An apparatus utilizes multiple strain gauge (“SG”) sensing units which are each disposed adjacent an inner surface of the device housing. Electrical voltage generated by the SGs is amplified by one or more amplifiers to maximize the resolution between a voltage output of an SG when in a non-pressed state and a voltage output of the SG when in a pressed state. Additionally, an electronic circuit is configured to identify a baseline voltage output for an SG over a period of time for comparing to a voltage output for the SG when the SG is in a pressed state such that the pressed state of the SG can be identified by the electronic circuit by comparing a current output voltage of the SG to the identified baseline voltage.

Abstract: In one general aspect, a method can include identifying contact with a surface of a touch-sensitive input device, identifying a location of the contact on the surface of the touch-sensitive input device, and calculating a change in a mutual capacitance between a first electrode and a second electrode included in a sensor module disposed below the surface of the touch-sensitive input device. The first electrode can be adjacent to the second electrode. The first electrode and the second electrode can be located approximate to the identified location of the contact on the surface of the touch-sensitive input device. The method can include estimating a contact-coupled capacitance based on the calculated change in a mutual capacitance between the first electrode and the second electrode, and calculating a force applied to the surface of the touch-sensitive input device at the identified location.
