    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.

Allocation of a first process identifier by the first one of the multiple applications in the first container is detected. The first process identifier is unique within the first container. A first unique identifier is allocated to the first one of the multiple applications. The launch of a second one of the multiple applications is delayed but subsequently launched if the first unique identifier has been allocated to the first one of the multiple applications. A second unique identifier is allocated to the second one of the multiple applications. The first and second unique identifiers uniquely identify the respective first and second ones of the multiple applications within the supervisor module.

    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: Groove analysis in a device having a tactile input surface suited to detect more than one tactile input at a time. Using groove analysis allows a touch screen device a more robust and efficient algorithm for distinguishing between two different tactile inputs. The touch screen device may include a touch screen controller that includes an analysis circuit for determining grooves between touch inputs. Generally, when a touch input is received at the surface of a touch screen device, the touch screen may register touch strength signals at each of a plurality of touch regions. A groove may be generally defined as a touch region that exhibits a touch strength signal that is less than surrounding touch regions. Once all touch regions are analyzed by a groove analysis, various touch regions determined to grooves may be eliminated from a further analysis to determine the XY coordinates of actual touch inputs.
