Abstract: A device may include a touch sensor for determining portions of a touchscreen display that receive touch inputs, and a motion sensor for identifying device motions of the device. Additionally, the device may include a processor to identify coordinates of a portion of the touchscreen display that receives a touch input, identify an input instant at which the touchscreen display receives the touch input, and determine a change of device motion that affects an accuracy of the coordinates of the touch input based on the input instant. In addition, the processor may adjust the coordinates based on the determined change of device motion.

Abstract: The invention is directed to systems, methods and computer program products for switching between a dry mode and a wet mode for a mobile device. An exemplary method comprises: determining a first capacitance on a mobile device touchscreen using a sensor associated with the touchscreen, wherein the first capacitance is determined when the touchscreen is submerged under a body of water; comparing the first capacitance to a threshold capacitance; determining whether the first capacitance is greater than or equal to the threshold capacitance; and in response to determining the first capacitance is greater than or equal to the threshold capacitance, switching the touchscreen from a dry mode to a wet mode, wherein in the wet mode, a location associated with a user's touch is determined based on a capacitance at a point on the touchscreen associated with the user's touch being less than the first capacitance.

Abstract: This invention relates to a method for knock detection in a combustion engine, in which combustion is controlled by a control unit (2), which comprises the steps of, a) obtaining at least one sensor signal (4, 4?) carrying information of knock intensity related within a combustion chamber of the combustion engine (1); (b) processing the sensor signal (4, 4?) to obtain a knock intensity related detection variable (z1), (c) using said detection variable (z1) in said control unit (2) arranged to avoid a knocking condition in said combustion engine (1), if the value (z1) of said detection variable indicates knock when compared with a threshold value (T) wherein using two different computations/processes for said processing (5, 6) of the at least one sensor signal (4, 4?) to obtain two separate sub-values (y1, y2), and thereafter combining said sub-values (y1, y2) to obtain said detection variable (z1).
