Abstract: This relates to a method of extrapolating proximity information to generate a border column or row of touch nodes (also known as touch pixels) and then fitting an ellipse to the contact patch including the extrapolated border touch nodes. Additionally, a contact can be identified as a thumb based on both its major axis and its distance to an edge of the touch sensing surface.

Abstract: An electronic device detects a touch input. After a latency period, the device delivers to an application a sequence of input events that represent the touch input, including, in sequence: a first input event that represents the touch input at a first input time and is delivered at a first delivery time, a second input event that represents the touch input at a second input time and is delivered at a second delivery time, and a third input event that represents the touch input at a third input time and is delivered at a third delivery time, a time interval between the second input time and the second delivery time is smaller than a time interval between the first input time and the first delivery time, and a time interval between the third input time and the third delivery time is smaller than the time interval between the second input time and the second delivery time.

Abstract: Reconstruction of an original touch image from a differential touch image is disclosed. Reconstruction can include aligning columns of the differential touch image relative to each other and aligning the image to a baseline DC value. The column and baseline alignment can be based on the differential image data indicative of no touch or hover, because such data can more clearly show the amount of alignment needed to reconstruct the original image. The reconstruction can be performed using the differential image data alone. The reconstruction can also be performed using the differential image data and common mode data indicative of the missing image column average.
