摘要： Matrix-based touch input systems assess touch locations of two or more temporally overlapping touch inputs by forming valid x-y coordinate pairs from independently determined x- and y-coordinates. Valid x-y pairs are formed based on comparing one or more signal parameters such as signal magnitude, signal strength, signal width, and signal rates of change. In matrix capacitive systems where capacitance-to-ground signals are used to determine the x- and y-coordinates, the determined coordinates may be formed into valid x-y pairs using mutual capacitance measurements. When resolving more than two temporally overlapping touches, information gained by resolving a valid x-y coordinate pair of at least one of the touches may be used to resolve the remaining touches.

摘要： A touch-sensitive device includes a touch panel, a drive unit, a sense unit, and a measurement unit. A touch applied to a node of the panel changes a capacitive coupling between two electrodes (a drive electrode and a sense electrode) of the touch panel. The drive unit delivers a drive signal, which may comprise one or more drive pulses, to the drive electrode. The sense unit couples to the sense electrode, and generates a response signal that includes a differentiated representation of the drive signal, which is then fed through a resistor. The amplitude of the response signal is responsive to the capacitive coupling between the electrodes, and is measured to provide an indication of a touch at the node.

摘要： Systems and methods determine the position of a touch on a surface of a device, such as a touch-sensitive device, by using passively-induced position-dependent electrical charges. In such a method, the position of a touching implement is determined on the sensing surface of a device. The method includes charging the sensing surface during a first time period by connecting all four corners of the sensing surface to a reference voltage, and over a second time period discharging two adjacent corners of the sensing surface into an integrator capacitor while connecting the two opposite corners to ground. The first and second time periods together form a charge/discharge cycle that is repeated a plurality of times, after which an output of the integrator capacitor is measured. This sequence is performed for each of the four pairs of adjacent corners of the sensing surface, resulting in four integrator capacitor output measurements, each of the four measurements being associated with a different sensing surface edge. The position of the touching implement on the sensing surface is then calculated using the four charge measurements.

摘要： A touch sensing method and a touch sensing device (100) are described for sensing a location of a touch. When the touch sensing device (100) is touched, a first conductive layer (110) disposed on a supporting layer (115) is deflected toward a second conductive layer (120). The touch location is determined by sensing the change in capacitance at the location of the touch. A change in capacitance at the touch location is sensed by driving one of the conductive layers (110, 120) with an electrical signal referenced to the other conductive layer (120, 110) and measuring the current flow between the conductive layers (110, 120). The sensed change in capacitance is greater than a change in the external capacitance of the touch sensor.
