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： 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.

摘要： The current invention is directed to optical MEM devices and methods for making the same. MEM devices, in accordance with the current invention, have one or more movable micro-structures which are preferably ribbon structures or cantilever structures configured for modulating light. The movable micro-structures are patterned from a device layer comprising a silicon nitride under-layer, a reflective metal top-layer and a ceramic compensating layer. The ceramic compensating layer is provided. to reduce stress in the micro-structures which can lead to curvature. In accordance with the embodiments of the invention, the device layer is formed on a silicon substrate that is preferably etched with trenches before forming the device layer. The device layer is then patterned using lithographic masking and etching techniques to release the patterned device layer and form the movable micro-structures. Portions of the device layer which are formed over the trenches provide support for the released patterned device layer.

The hybrid SLM includes a substrate having an upper surface, a number of movable ribbons disposed a predetermined distance above the upper surface of the substrate, the ribbons having light reflective surfaces formed on their upper side facing away from the upper surface of the substrate, and a number of standoffs having a predetermined height positioned between a lower surface of the movable ribbons and the upper surface of the substrate. The standoffs are configured to limit the ribbon deflection of movable ribbons toward the upper surface of the substrate when the SLM is operated in digital mode with snap-down voltages applied between the ribbon and drive electronics in the substrate. Other embodiments are also disclosed.
