Embodiments of the present invention may provide a device to adaptively generate a haptic effect. The device may include a controller to generate a haptic command associated with a haptic profile and a haptic driver to generate a drive signal based on the haptic command, wherein the drive signal causes an actuator to produce vibrations corresponding to a haptic effect. Further, the device may include a sensor, coupled mechanically to the actuator, to measure at least one property of the vibrations. The controller may adjust the haptic command according to the measured at least one property. Therefore, the device may continuously tune haptic effect generation according to vibration measurements.

Method and apparatus for haptic vibration response profiling and feedback

A touch screen controller has a converter that digitizes analog input as a function of an interference signal generated by an underlying touch screen device. To that end, the touch screen controller includes a set of inputs for receiving the noted interference signal from the touch screen device. The set of inputs also receives analog data from the touch screen device. The above noted converter, which is operatively coupled with the set of inputs, is capable of digitizing the analog data received from the touch screen device as a function of the interference signal.

Analog to digital converter controller

A clock scheme for a system on a chip wherein integral sub-multiples of a system clock have positive edges on odd-numbered positive edges of the system clock and negative edges on even-numbered positive edges Data transfer between blocks of different frequencies is controlled by a state machine of the higher frequency block and can be achieved without elastic buffers and/or synchronizers.
