    摘要: Compensation for signal drift in a touch and hover sensing device is disclosed. A touch and hover sensing device can include a sensing panel to sense an object touching or hovering over the panel, a grounding device to periodically interact with the panel, and a control system to measure capacitance of the panel when the grounding device interacts with the panel, where the measurement captures any signal drift in the panel, and to set the measurement as a new baseline capacitance of the panel. Alternatively, the touch and hover sensing device can forgo the grounding device and configure the control system to measure capacitance of the panel either when there has been no touching or hovering object or when there is a substantially stationary touching or hovering object at the panel for a determinative time period, where the measurement captures any signal drift in the panel, and to set the measurement from this time period as the new baseline capacitance. The control system can apply the new baseline capacitance to touch and hover measurements so as to compensate for the signal drift.

    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.
