Abstract: A camera is disclosed. The camera includes an image sensor and a f-theta lens fixed relative to the image sensor. The f-theta lens is configured to direct object light from a scene onto the image sensor. An optical axis of the f-theta lens is offset from an optical center of the image sensor such that the image sensor is configured to capture a field of view having an angular bias relative to the optical axis of the f-theta lens.

Abstract: Methods for estimating a force F exerted on a touchpad are disclosed. In one example, a force sensing touchpad comprises a printed circuit board (PCB) comprising four PCB electrodes and a spring spaced from the PCB and comprising four spring electrodes. Changes in capacitance at two of the PCB electrodes are determined and used to calculate a first local gradient between the two electrodes. Changes in capacitance at the other two PCB electrodes are determined and used to calculate a second local gradient between these two electrodes. The local gradients are used to calculate local forces at each PCB electrode, and the local forces are used to calculate the force F exerted on the touchpad.
