Abstract: An intelligent stylus is disclosed. The stylus can provide a stylus condition in addition to a touch input. The stylus architecture can include multiple sensors to sense information indicative of the stylus condition, a microcontroller to determine the stylus condition based on the sensed information, and a transmitter to transmit the determined condition to a corresponding touch sensitive device so as to cause some action based on the condition.

Abstract: The suppression of errant motion regarding a mouse is disclosed. Mouse and touch information can be integrated to determine whether a gesture made on a surface of the mouse is errant, such as when a mouse is being moved and the fingers holding the mouse inadvertently move on the mouse surface. A gesture motion that is small relative to mouse motion can be considered errant and therefore at least partially suppressed, while a gesture motion that is large relative to mouse motion can be considered an intended gesture and therefore processed. Similarly, mouse and touch information can be integrated to determine whether a mouse motion is errant, such as when a robust gesture being made on the mouse surface inadvertently moves the mouse. A mouse motion that is small relative to gesture motion can be considered errant and therefore at least partially suppressed, while a mouse motion that is large relative to gesture motion can be considered an intended motion and therefore processed.

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: Embodiments are related to user input devices that accept complex user input including a combination of touch and push (or pick) input. Embodiments of the invention provide for selective ignoring or rejection of input received from such devices in order to avoid interpreting unintentional user actions as commands. Furthermore, some input signals can be modified. The selective rejection or modification can be performed by the user interface device itself or by a computing device that includes or is attached to the user interface device. The selective rejection or modification may be performed by a module that processes input signals, performs the necessary rejections and modifications and sends revised input signals to higher level modules.

Abstract: A touch input device configured to synchronize a stylus acquisition process with both a touch data acquisition process and a display refresh process is provided. The touch input device can include one or more processors that can synchronize the stylus data acquisition process to the touch data acquisition process by coordinating stylus scans to take place in between touch scans. The one or more processors can also virtual data banks to synchronize both the touch data acquisition and the stylus scan acquisition with the display refresh process.

Abstract: Combined force and proximity sensing is disclosed. One or more sensors can concurrently sense a force applied by an object on a device surface and a proximity of the object to the surface. In an example, a single sensor can sense both force and proximity via a resistance change and a capacitance change, respectively, at the sensor. In another example, multiple sensors can be used, where one sensor can sense force via either a resistance change or a capacitance change and another sensor can sense proximity via a capacitance change.

Abstract: A touch sensor panel is disclosed. The touch sensor panel includes a plurality of rows, at least one of the rows being a split row including a plurality of row subsections; and a plurality of columns, at least one of the columns being a split column including a plurality of column subsections. The touch sensor panel is configured with at least one split row and at least one split column located to increase a likelihood that a touch anywhere on the touch sensor panel overlaps with at least one split row and at least one split column. The rows and columns are individually charged electrodes capable of detecting a change in capacitance in a corresponding area of the touch sensor panel.

Abstract: This relates to compensation for undesirable capacitance changes in a touch sensing device, where the capacitance changes are not indicative of a touch at the device. The touch sensing device can include a touch sensor panel having touch sensors for sensing a touch at the panel, a flexible circuit for transmitting the sensed touch signal from the panel, and a touch controller for receiving and processing the transmitted signal. To compensate for the capacitance changes, the touch sensing device can include one or more reference conductive traces decoupled from touch sensors of the device to measure non-touch capacitances in the device. The touch sensing device can then adjust a touch signal from the touch sensors using the non-touch capacitance measurements to substantially reduce or eliminate the non-touch capacitances from the signal.

Abstract: Data acquisition from a touch-surface input unit may be disrupted during the generation of radio frequency (“RF”) pulses. To mitigate this problem, touch-surface data acquisition is temporarily halted during RF pulse generation. Data collected prior to temporarily halting is retained, with subsequently acquired data being added to prior collected data.
