    Abstract: Certain aspects provide a method for determining a solution to a combinatorial optimization problem, including: determining a plurality of subgraphs, wherein each subgraph of the plurality of subgraphs corresponds to a combinatorial variable of the plurality of combinatorial variables; determining a combinatorial graph based on the plurality of subgraphs; determining evaluation data comprising a set of vertices in the combinatorial graph and evaluations on the set of vertices; fitting a Gaussian process to the evaluation data; determining an acquisition function for vertices in the combinatorial graph using a predictive mean and a predictive variance from the fitted Gaussian process; optimizing the acquisition function on the combinatorial graph to determine a next vertex to evaluate; evaluating the next vertex; updating the evaluation data with a tuple of the next vertex and its evaluation; and determining a solution to the problem, wherein the solution comprises a vertex of the combinatorial graph.

    Abstract: Techniques are described for testing a capacitive touch panel for the presence or absence of discontinuities. A pixel matrix is determined for a capacitive touch panel. The pixel matrix comprises pixel values representative of mutual capacitance of respective pixels of the capacitive touch panel. A difference matrix is generated from the pixel matrix. The difference matrix contains differences in pixel values for respective pixels of the capacitive touch panel with respect to pixel values of adjacent pixels. A determination may then be made from the difference matrix whether respective ones of the pixels of the capacitive touch panel contain a discontinuity.

    Abstract: Systems and methods relate to a network on chip (NoC) which includes one or more channels configured to carry data packets in a first direction, the first direction having an upstream end and a downstream end. A tunnel is configured between an upstream element at the upstream end and a downstream element at the downstream end. The tunnel includes common wires which are shared by the one or more channels. The tunnel is configured to transmit data packets of two or more formats on the common wires based on common signals. common signals comprise data signals to transmit one or more of data, control, or debug information belonging to the data packets on the common wires, and framing signals to control transmission of the data signals on the common wires.

    Abstract: A touch panel sensor system that can dynamically measure noise and automatically switch to a frequency with minimal noise is described. The touch panel sensor system includes a sensor configured to detect a change in capacitance associated with a touch upon a touch panel. The system also includes a drive module configured to generate a drive signal having a first waveform characteristic (e.g., signal having a periodic waveform characteristic) during a first phase (e.g., sensor phase) and a second drive signal having a second waveform characteristic (e.g., constant voltage signal) during a second phase (e.g., noise detection phase). The first and second drive signals are configured to drive the sensor. The system also includes a measuring module coupled to the sensor that is configured to measure noise having the first waveform characteristic (e.g., periodic waveform characteristic) during the second phase.

    Abstract: Systems and methods are described comprising receiving at a platform device data of a client device and storing the device data in a data block allocated to the client device. A control command for the client device is received from a service application, and the control command is accepted at a device controller. The device controller accepts the control command on behalf of the client device. The device controller, in response to the control command, retrieves the device data from the data block instead of receiving the device data directly from the client device, and provides the device data to the service application. Subsequent to provision of the device data to the service application, the device controller relays the control command to the client device, and the client device executes the command.
