摘要： A location of contact with a touch sensitive device is determined. Output signals associated with a plurality of electrodes such as formed on a single layer of the touch sensitive device are measured to identify a first electrode positioned at an approximate location of contact with the touch sensor. An output signal associated with a different electrode that is separated from the first electrode is measured to determine an undesired signal amount, such as due to deflection. An undesired single amount associated with the first electrode may be estimated based on the undesired signal amount measured at the other electrode. The signal amount measured at the first electrode is then compensated by the estimated undesired signal amount. The location of contact with the touch sensor is then determined based on the compensated signal amount.

摘要： The present invention relates to a method for reducing noise in a signal sensing a bending wave propagating in an object comprising the steps of: receiving a sensed signal representative of a plurality of locations of the object, and fitting a function satisfying bending wave propagation properties to the sensed signals, thereby reducing noise contributions to the sensed signals not satisfying the bending wave propagation properties. By doing so, noise contributions not satisfying the wave propagation properties can be suppressed from the sensed signal, thereby improving the signal-to-noise ratio.

摘要： A touch sensor comprises a substrate capable of propagating acoustic waves and includes a first surface having a touch sensitive region. A first sidewall intersects the first surface along a first edge. The first edge is configured to propagate a first acoustic wave along the first edge. The first acoustic wave may be a one-dimensional edge wave. A wave converter converts the first acoustic wave to a second acoustic wave, and the first surface is configured to propagate the second acoustic wave across the touch sensitive region.

摘要： A location of contact with a touch sensitive device is determined. Values associated with each electrode of a plurality of electrodes formed on a single layer of the touch sensitive device are sampled. A determination is made as to whether a contact with the touch sensitive device has occurred. Values sampled subsequent to the contact are adjusted based on selected stored sampled values. A location of contact is then determined based on the adjusted values.

摘要： A touch panel includes a substrate that has top and bottom surfaces. A reflective image layer has top and bottom surfaces and displays an image. The bottom surface of the reflective image layer is bonded to the top surface of the substrate to form a stack having top and bottom sides. At least one sensor detects signals associated with bending waves propagating through the stack. The signals are used to identify coordinate locations of at least one touch event on the top or bottom sides of the stack, or to identify coordinate locations of touch events on both of the top and bottom sides of the stack.

摘要： The present invention provides a way to measure and track non-linear corrections in touchscreens. Some or all of the relevant non-linear corrections may be determined automatically. Production floor test equipment may make electronic measurements, compute parameters, and load the parameters in non-volatile memory of the controller electronics. Alternatively, the controller electronics can make the electronic measurements and determine non-linear parameters. The latter embodiment of the invention permits the determination of non-linear parameters in the field, dynamically tracking changes in the non-linear characteristics of installed touchscreens that occur over time or due to environmental conditions.
