摘要： 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.

摘要： Detecting a signal from a touch and hover sensing device, in which the signal can be indicative of concurrent touch events and/or hover events, is disclosed. A touch event can indicate an object touching the device. A hover event can indicate an object hovering over the device. The touch and hover sensing device can ensure that a desired hover event is not masked by an incidental touch event, e.g., a hand holding the device, by compensating for the touch event in the detected signal that represents both events. Conversely, when both a hover event and a touch event are desired, the touch and hover sensing device can ensure that both events are detected by adjusting the device sensors and/or the detected signal. The touch and hover sensing device can also detect concurrent hover events by identifying multiple peaks in the detected signal, each peak corresponding to a position of a hovering object.

摘要： Compensation for sensors in a touch and hover sensing device is disclosed. Compensation can be for sensor resistance and/or sensor sensitivity variation that can adversely affect touch and hover measurements at the sensors. To compensate for sensor resistance, the device can gang adjacent sensors together so as to reduce the overall resistance of the sensors. In addition or alternatively, the device can drive the sensors with voltages from multiple directions so as to reduce the effects of the sensors' resistance. To compensate for sensor sensitivity variation (generally at issue for hover measurements), the device can apply a gain factor to the measurements, where the gain factor is a function of the sensor location, so as to reduce the sensitivity variation at different sensor locations on the device.

摘要： Signal processing for a touch and hover sensing display device is disclosed. A touch and hover sensing display device can include a sensing panel for sensing a touch or hover event, a display for displaying graphical information to select based on the touch or hover event, and a control system for processing a signal indicative of the touch or hover event. The control system can process the signal to determine to which display location a hovering object is pointing according to a profile of the object's shape. In addition or alternatively, the control system can process the signal to differentiate between a close small object and a distant large object so as to subsequently perform intended actions of the device based, at least in part, on the object distance and/or area (or size). The display can be positioned at a desirable distance from the panel so as to reduce interference from the display to the panel and avoid adverse effects on the signal.

摘要： Touch and hover switching is disclosed. A touch and hover sensing device can switch between a touch mode and a hover mode. During a touch mode, the device can be switched to sense one or more objects touching the device. During a hover mode, the device can be switched to sense one or more objects hovering over the device. The device can include a panel having multiple sensors for sensing a touching object and/or a hovering object and a touch and hover control system for switching the device between the touch and hover modes. The device's touch and hover control system can include a touch sensing circuit for coupling to the sensors to measure a capacitance indicative of a touching object during the touch mode, a hover sensing circuit for coupling to the sensors to measure a capacitance indicative of a hovering object during the hover mode, and a switching mechanism for switching the sensors to couple to either the touch sensing circuit or the hover sensing circuit. The device can switch modes based on a condition of the device, such as an expiration of a timer or a relative distance of an object from the panel.

摘要： A modulator for and a method of modulating an incident beam of light including means for supporting a plurality of active elements and a plurality of bias elements, each active and bias element including a light reflective planar surface with the light reflective planar surfaces of the plurality of active elements lying in a first parallel plane and the plurality of bias elements lying in a second parallel plane wherein the plurality of active and bias elements are parallel to each other and further wherein the plurality of bias elements are mechanically or electrically deflected with respect to the plurality of active elements. Each of the plurality of bias elements is deflected an odd multiple of the wavelength of an incident light wave divided by four and the plurality of light reflective planar surfaces of the plurality of active elements move between the first parallel plane to the second parallel plane. The deflection of bias elements is optimized to minimize optical attenuation error due to voltage error.

摘要： Detecting a signal from a touch and hover sensing device, in which the signal can be indicative of concurrent touch events and/or hover events, is disclosed. A touch event can indicate an object touching the device. A hover event can indicate an object hovering over the device. The touch and hover sensing device can ensure that a desired hover event is not masked by an incidental touch event, e.g., a hand holding the device, by compensating for the touch event in the detected signal that represents both events. Conversely, when both a hover event and a touch event are desired, the touch and hover sensing device can ensure that both events are detected by adjusting the device sensors and/or the detected signal. The touch and hover sensing device can also detect concurrent hover events by identifying multiple peaks in the detected signal, each peak corresponding to a position of a hovering object.
