A manager module is configured to detect a user selection of an application and configured to initiate a launch process. A supervisor module is configured to intercept the launch process initiated by the manager module and detect whether the application is a trusted application or an untrusted application. Trusted applications have a privilege to access resources without authorization, and untrusted applications do not have the privilege. The supervisor module has the privilege to access the resources. When the application is untrusted, the application is launched in a container, and at least one of the resources is delivered to the untrusted application in the container.

Abstract: A capacitive touch system generates data indicative of sensed capacitance measured at capacitive sensing nodes of a capacitive touch panel. A signal processing circuit is coupled to receive the data indicative of sensed capacitance from the capacitive touch system. The signal processing circuit operates to fit a parabolic curve to the data indicative of sensed capacitance. A sharpness of the fit parabolic curve is indicative of whether touch versus hover interaction with the capacitive touch panel. A touch detection threshold is as a function of the determined sharpness. The set touch detection threshold is then applied against the data indicative of sensed capacitance in order to make a touch detection.

Abstract: A touch panel includes capacitive sensing electrodes and a touch controller operates in a first operating mode to detect a touch location on the touch panel. In a second operating mode, the touch controller transmits a modulated data signal through the touch panel to an active stylus. Each electrode is driven by a line driver circuit. A control circuit selectively actuates first ones of the line driver circuits to pass the modulated data signal to corresponding first ones of the electrodes which do not pass through a region of the touch panel associated with the location of the detected touch. Simultaneously, the control circuit selectively actuates second ones of the line driver circuits, different from said first ones of the line driver circuits, to ground corresponding second ones of the electrodes which do pass through the region of the touch panel associated with the location of the detected touch.

Abstract: A touch screen system is configured to sense a proximate or actual touch made to a touch screen panel. In response thereto, an RF transmitter is actuated to emit RF energy. A stylus receives the emitted RF energy and includes an RF energy harvesting circuit that powers an enable circuit. The enable circuit generates an enable signal. The stylus responds to the enable signal by performing a sensing operation. The information collected in the sensing operation is then communicated over an RF communications link back to the touch screen system. The sensing operation preferably is a pressure sensing operation for detecting an applied pressure at an end of the stylus resulting from contact with the touch screen panel.

Abstract: An active stylus is capacitively coupled to a capacitive touch panel for communication. The active stylus operates in a wait mode to receive initial communications from the panel. In response to such receipt, the active stylus synchronizes to a repeating communications frame implementing time division multiplexing. Communications from the active stylus to the panel include: information communications; synchronization communications and communications specific for columns and/or rows of the panel. Communications from the panel to the active stylus may be addressed uniquely to the stylus or commonly to a group of styluses.

Abstract: A single ITO layer design for a touchscreen panel incorporates a matrix of sensor cells formed from a single ITO layer of capacitive sensor pads, sensor bars, force lines and sense lines. Columns of multiplexed force lines are connected to rows of sensor pads to form force trees such that the force line of the end pair of sensor pads has a wide track, with the force lines of each subsequent pair of sensor pads having a reduced track width. Disposed between the columns of force trees, the matrix of sensor cells also includes columns of sensor bars connected to control circuitry via sense lines. The control circuitry applies a signal to the force trees to generate capacitance between rows of sensor pads and adjacent sensor bars. The control circuitry senses changes in the capacitance and resolves the location of a user touch in the matrix of sensor cells.
