Abstract: A touch controller is coupled to a touch screen and detects a first gesture at a first point on the touch screen. The first gesture includes physical contact of the touch screen by a user device at the first point. The touch controller detects a second gesture that is associated with movement of the user device from the first point to a second point on the touch screen. The second gesture includes detecting movement of the user device within a sensing range from the first point to the second point. The sensing range corresponds to an orthogonal distance from a surface of the touch screen. The touch controller detects a third gesture at the second touch point. The third gesture includes physical contact of the touch screen at the second touch point. Upon detecting the first, second and third gestures the touch controller performs a corresponding action.

Abstract: A system and method for synchronizing two devices in communication with each other. When communication between the two devices is to be established, a synchronization process may be invoked. In an embodiment, a first device may initiate sending synchronization signals having rising edge and falling edge pairs. The second device may include a controller configured to receive the synchronization signals. However, noise may inhibit the ability of the controller to correctly receive and/or interpret the synchronization signals. Noise may cause detection components to falsely detect noise as a synchronization signal or may cause detection components to miss detection of an actual synchronization signal. A window generator may be used to generate comparison windows for the controller to detect synchronization signals. Further, the detection window duration and start times may be adjusted based on previously detected (or undetected) synchronization signals in order to compensate for noise overshadowing synchronization signals.

Abstract: A start/stop condition detection circuit is coupled to receive the SDA and SCL signals from an IIC Bus. The circuit generates a first signal in response to an edge of the SDA signal and generates an inversion of the first signal as a second signal in response to an opposite edge of the SCL signal. The first and second signals are logically combined to generate an output signal. The particular directions of the edges of the SDA and SCL signals that the circuit is response to determines whether the output signal is indicative of a start condition detection or a stop condition detection.

Abstract: The back EMF (BEMF) of a motor is sensed and compared to a target back EMF (BEMF) to generate an error control signal. The circuit supply voltage is also sensed. A PWM motor control signal is generated in response to a comparison of the error control signal to a ramp signal having a variable slope. The variable slope is selected in response to the sensed circuit supply voltage. The motor is then driven in response to the PWM control signal. The sign of the error control signal is used to selectively short one of motor terminals to a reference voltage supply node while the other motor terminal is driven in response to the PWM control signal.

Abstract: A system for determining an aspect ratio of image content based on an analysis of the content. In an embodiment, an analyzer is configured to receive a data input corresponding to an image in a stream of images that constitute a video sequence of images. The analyzer is further configured to determine a mathematical representation of the image content based on a power spectrum analysis of vertical components of the image in comparison to a power spectrum analysis of horizontal components of the image. Based on this comparison of the vertical frequency components to the horizontal frequency components, a determination about the original aspect ratio of the image may be determined. This determination may be used by a video processor to correctly apply aspect ratio conversion for final image output.
