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: According to one embodiment of the present disclosure, a touch controller is adapted to be coupled to a touch screen and to a motion sensor. The touch controller is operable in response to a signal from the motion sensor indicating a first motion to switch from a hover event sensing mode of operation to a gesture event sensing mode of operation. In one embodiment, the touch controller is operable in the hover event sensing mode of operation to detect a first hover event and is thereafter operable, in response to the signal from the motion sensor indicating a first motion has occurred, to switch to the gesture event sensing mode of operation and detect a first gesture event.

Abstract: An embodiment of a receiver includes signal- and data-recovery units. The signal-recovery unit is configured to recover a first component of a first signal that is received simultaneously with a second signal having a second component, the first and second components including approximately a frequency. And the data-recovery unit is configured to recover data from the first signal in response to the recovered first component. For example, such a receiver may be able to receive simultaneously, and over the same channel space, multiple orthogonal-frequency-division-multiplexed (OFDM) signals that include one or more of the same subcarrier frequencies, and to recover data from one or more of the OFDM signals despite the frequency overlap. A receiver with this capability may allow an increase in the effective bandwidth of the channel space, and thus may allow more devices (e.g., smart phones) to simultaneously share the same channel space.

Abstract: An electronic device may include a first controller associated with some channels of a digitizer having channels configured to receive a signal from a stylus, and with each channel having a direction. A second controller may be associated with channels of the digitizer not associated with the first controller. The first controller may scan for the signal at each channel associated with the first controller, and based on acquisition of the signal at a given channel associated with the first controller, calculate a property of the signal. The first controller may send the calculated property and the direction of the given channel to the second controller. The first controller and the second controller may scan for the signal at each channel having the direction of the given channel, at acquisition intervals based upon the calculated property.

Abstract: A supervisor module manages multiple user selected applications. A first one of the multiple applications is launched in a first container. 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: Embodiments are directed to microfluidic refill cartridges and methods of assembling same. The microfluidic refill cartridges include a microfluidic delivery member that includes a filter for filtering fluid passed therethrough. The filter may be configured to block particles above a threshold size to prevent blockage in the nozzles. For instances, particles having a dimension that is larger than the diameter of the nozzles can block or reduce fluid flow through the nozzle.
