Abstract: Es wird ein Ultraschall-Berührungserfassungssystem offenbart, das sowohl Kompressions- als auch Scherwellen zur Berührungs- und Wassererkennung verwendet. Wenn keine Berührung oder kein Wasser vorhanden ist, wird weniger Scher- und Kompressionswellen-Energie absorbiert, so dass sowohl Scher- als auch Kompressionswellenreflexionen keine signifikanten Amplitudenabnahmen aufweisen. Wenn ein Finger die Erfassungsplatte berührt, wird sowohl Scher- als auch Kompressionswellen-Energie absorbiert, so dass sowohl Scher- als auch Kompressionswellenreflexionen signifikante Amplitudenabnahmen aufweisen. Wenn Wasser mit der Erfassungsplatte in Kontakt kommt, wird Kompressionsenergie absorbiert, jedoch wenig oder keine Scherwellen-Energie absorbiert, so dass Kompressionswellenreflexionen zwar signifikante Amplitudenabnahmen aufweisen, Scherwellenreflexionen jedoch nicht. Aus diesen Amplituden kann bestimmt werden, ob keine Berührung auf der Erfassungsplatte vorhanden ist, ob eine Berührung auf der Erfassungsplatte vorhanden ist oder ob Wasser auf der Erfassungsplatte vorhanden ist.

Abstract: Improved capacitive touch and hover sensing with a sensor array is provided. An AC ground shield positioned behind the sensor array and stimulated with signals of the same waveform as the signals driving the sensor array may concentrate the electric field extending from the sensor array and enhance hover sensing capability. The hover position and/or height of an object that is nearby, but not directly above, a touch surface of the sensor array, e.g., in the border area at the end of a touch screen, may be determined using capacitive measurements of sensors near the end of the sensor array by fitting the measurements to a model. Other improvements relate to the joint operation of touch and hover sensing, such as determining when and how to perform touch sensing, hover sensing, both touch and hover sensing, or neither.

Abstract: Improved capacitive touch and hover sensing with a sensor array is provided. An AC ground shield positioned behind the sensor array and stimulated with signals of the same waveform as the signals driving the sensor array may concentrate the electric field extending from the sensor 5 array and enhance hover sensing capability. The hover position and/or height of an object that is nearby, but not directly above, a touch surface of the sensor array, e.g., in the border area at the end of a touch screen, may be determined using capacitive measurements of sensors near the end of the sensor array by fitting the measurements to a model. Other improvements relate to the joint operation of touch and hover sensing, such as determining when and how to perform touch 0 sensing, hover sensing, both touch and hover sensing, or neither.

Abstract: Ground detection of a touch sensitive device is disclosed. The device can detect its grounded state so that poor grounding can be selectively compensated for in touch signals outputted by the device. The device can include one or more components to monitor certain conditions of the device. The device can analyze the monitored conditions to determine the grounding condition of the device. The device can apply a function to compensate its touch signal outputs if the device determines that it is poorly grounded. Conversely, the device can omit the function if the device determines that it is well grounded.
