Abstract:
A device configured to sense a touch on a surface of the device. The device includes a cover and a force-sensing structure disposed below the cover. The force-sensing structure may be positioned below a display and used in combination with other force-sensing elements to estimate the force of a touch on the cover of a device.
Abstract:
A coated chassis is disclosed. The chassis can be made from a non-conductive material and can be operable to support a display. A conductive material can be applied to at least a portion of the chassis to form a continuous strip on the chassis frame. The conductive material can further form a closed-loop around the chassis frame. The chassis frame can be included within a device, such as a mobile phone, touchpad, portable computer, portable media player, and the like. The conductive material on the chassis can be coupled to the system ground of the device. Processes for making a coated chassis are also disclosed.
Abstract:
Touch sensitive mechanical keyboards and processes for detecting touch events and key depressions on the keyboard are provided. The touch sensitive mechanical keyboard can include a set of individually depressible mechanical keys having a touch sensitive area located on their surface. A touch sensor can be included to detect touch events on the surface of the keys. A keypad can also be included to detect a depression of the mechanical keys. One or more of the depressible mechanical keys can be multi-purpose keys capable of being depressed to multiple levels. The touch sensitive mechanical keyboard can receive key depression input, touch event input, or combinations thereof at the same time. The touch sensitive mechanical keyboard can further include a processor for distinguishing detected touch events from detected key depressions. The processor can generate a key depression command or a touch event command in response to the detected touch events and key depressions.
Abstract:
Flexible circuits for routing signals of a device, such as a touch sensor panel of a touch sensitive device, are provided. The flexible circuit can include a first set of traces for routing a first set of lines and a second set of traces for routing a second set of lines. The first set of traces can couple together the ends of at least a portion of the first set of lines. Additionally, the first set of traces can be non-intersecting or non- overlapping with the second set of traces. The flexible circuit can have a T-shape configuration and can be incorporated within a touch sensitive device, display device, printed circuit board, or the like. The flexible circuit can be placed over another flexible circuit, and can extend onto the device.

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.
