A device includes a substrate and a touch control interface including touch control electrodes laminated onto the substrate and a touch controller electrically connected to each touch control electrode. The touch controller is configured to detect a change in a capacitance of a first touch control electrode to determine that a user is touching the first touch control electrode. The device may include a high-pass filter connected to the first touch control electrode and an impedance matching network electrically connected to the high-pass filter. The device includes a radio controller connected to the impedance matching network. The radio controller is configured to use the first touch control electrode as a first antenna to transmit and receive wireless signals. The optional impedance matching network may be configured to match an input impedance of the first touch control electrode to an output impedance of the radio controller.

Integrated touch control electrode and antenna

A stylus () is configured for actively interacting with a touch-sensitive interface () by injecting or sinking charge in response to a touch-detection signal emitted from the touch-sensitive interface (). One stylus () includes a stylus body () and a compound tip () extending axially from the stylus body (). The compound tip () can include a center electrode () that is configured to detect electric field variations from the touch-sensitive interface () and a shroud electrode () that is concentrically disposed about the center electrode (). An active circuit () coupled between the center electrode () and the shroud electrode () is configured to apply a gain to the detected electric field variations and to change a potential of the shroud electrode () synchronously with the electric field variations detected by the center electrode ().

Active stylus for use with touch-sensitive interfaces and corresponding method

A method and apparatus for controlling a device is provided herein. During operation, a user's headset is tapped upon in order to control a device. More particularly, a user's headset (or the device itself) uses circuitry that allows the headset or the device to detect user taps (for example on either earpiece of the connected 3.5 mm jack stereo headset, or the housing of the headset). The taps serve as user inputs to control the device. Because a user can control a device simply by tapping upon a headset, the device can be accessed without necessitating the need to wake the device to access control functions (e.g., music control functions).

Method and apparatus for controlling a device

A method and system for determining a camera-to-display latency of an electronic device () having a camera () and touch-sensitive display () are disclosed. In one example embodiment, the method () includes receiving () first light () at the camera, and essentially simultaneously receiving second light () at a first photosensitive structural portion (). The method () further includes detecting () a first simulated touch input at the display () in response to a first actuation of the first photosensitive structural portion (), receiving third light () at a second photosensitive structural portion (), the third light being generated based at least indirectly upon the received first light (), detecting () a second simulated touch input at the display () as a result of the receiving of the third light (), and determining the camera-to-display latency based at least indirectly upon the touch inputs ().

Method and system for testing temporal latency in device having optical sensing component and touch-sensitive display component

A mobile device includes a touch screen display and touch screen circuit for receiving touch inputs. A camera configured to acquire one or more images in front of the display. A proximity sensor configured to provide an indication that a user is in close proximity to the touch screen display. A processor being effective to determine, in response to the indication of the proximity sensor, whether the user is in a position to view the display based on the one or more images of the camera. If the proximity sensor provides an indication that the user is in close proximity to the display and the processor determines, based on the one or more images, that the user is in a position to view the display, then at least one of the display and the touch screen circuit are not disabled.
