Abstract: Keyboards, keypads and other data entry devices can suffer from a keying ambiguity problem. In a small keyboard, for example, a user's finger is likely to overlap from a desired key to onto adjacent ones. An iterative method of removing keying ambiguity from a keyboard comprising an array of capacitive keys involves measuring a signal strength associated with each key in the array, comparing the measured signal strengths to find a maximum, determining that the key having the maximum signal strength is the unique user-selected key, and maintaining that selection until either the initially selected key's signal strength drops below some threshold level or a second key's signal strength exceeds the first key's signal strength.

Abstract: An exemplary touch position sensing panel includes an opaque electrode layer and a transparent electrode layer separated from the opaque electrode layer by a substrate. The electrodes are arranged such that nodes are formed in areas where the electrodes cross over each other. The transparent electrode layer shields the opaque layer from electric field noise from electric field sources underlying the position-sensing panel, such as a display, while at the same time providing transparency to light emitted from the underlying display. Techniques are also discussed for forming the transparent electrode layer and/or the opaque electrode layer.

Abstract: In a capacitive sensor of the type having X electrodes which are driven and Y electrodes that are used as sense channels connected to charge measurement capacitors, signal measurements are made conventionally by driving the X electrodes to transfer successive packets of charge to the charge measurement capacitors. However, an additional noise measurement is made by emulating or mimicking the signal measurement, but without driving the X electrodes. The packets of charge transferred to the charge accumulation capacitor are then indicative of noise induced on the XY sensing nodes. These noise measurements can be used to configure post-processing of the signal measurements.
