Abstract: A capacitive sensing device can include multiple capacitive sensors. A first device controller is operatively connected to a portion of the capacitive sensors, while a second device controller is operatively connected to another portion of capacitive sensors. A common node or shield can be connected between the first device controller and the second device controller. Charging and discharging events of selected drive lines in the capacitive sensing device and/or of the common node or shield can be synchronized to reduce undesirable effects such as noise and/or to prevent the charging events and the discharging events from overlapping with each other. One or more reference capacitive sensors can be shared by the multiple device controllers.

Abstract: A system can include a display, a first device, and a second device all operatively connected to a controller. The first and second devices each use or share at least a portion of the display area. The controller is adapted to transmit during a pixel refresh time period of the display a first signal that is received by the first device. The first sync signal indicates a first time period in which a first operation can be performed in the first device. The controller is also adapted to transmit a second sync signal that is received by the second device indicating a second time period in which a second operation can be performed in the second device. The second time period can be during the pixel refresh time period or outside of the pixel refresh time period.

Abstract: A force-sensitive device for electronic device. The force inputs may be detected by measuring changes in capacitance, as measured by surface flex of a device having a flexible touchable surface, causing flex at a compressible gap within the device. A capacitive sensor responsive to changes in distance across the compressible gap. The sensor can be positioned above or below, or within, a display element, and above or below, or within, a backlight unit. The device can respond to bending, twisting, or other deformation, to adjust those zero force measurements. The device can use measure of surface flux that appear at positions on the surface not directly the subject of applied force, such as when the user presses on a part of the frame or a surface without capacitive sensors.

Abstract: A device configured to determine the location and magnitude of a touch on a surface of the device. The device includes a transparent touch sensor that is configured to detect a location of a touch on the transparent touch sensor. The device also includes a force-sensing structure disposed at the periphery of the transparent touch sensor. The force sensor includes an upper capacitive plate and a compressible element disposed on one side of the upper capacitive plate. The force sensor also includes a lower capacitive plate disposed on a side of the compressible element that is opposite the upper capacitive plate.

Abstract: Touch pad structures are provided that gather touch sensor data. The data may be used to control a computer or other electronic device. The touch pad structures may be integrated into a computer or other computing equipment or may be provided as a stand-alone accessory. The touch pad structures may include a touch sensor array. The touch sensor array may include rows and columns of touch sensor electrodes, interconnect lines, and other conductive structures. The conductive structures on the touch sensor array may be formed from patterned layers of ink. Interconnect line segments in different layer of ink may be connected in rectangular contact regions. The touch sensor array may have a tail. A layer of insulator may be removed from the substrate across a tip portion of the tail to allow the line segments to be connected.
