Abstract: A method for labeling a spherical target includes receiving an input including a representation of an object. The method also includes estimating unconstrained coordinates corresponding to the object. The method further includes estimating coordinates on a sphere by applying a spherical exponential activation function to the unconstrained coordinates. The method also associates the input with a set of values corresponding to a spherical target based on the estimated coordinates on the sphere.

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: Non-volatile (NV)-content addressable memory (CAM) (NV-CAM) cells employing differential magnetic tunnel junction (MTJ) sensing for increased sense margin are disclosed. By the NV-CAM cells employing MTJ differential sensing, differential cell voltages can be generated for match and mismatch conditions in response to search operations. The differential cell voltages are amplified to provide a larger match line voltage differential for match and mismatch conditions, thus providing a larger sense margin between match and mismatch conditions. For example, a cross-coupled transistor sense amplifier employing positive feedback may be employed to amplify the differential cell voltages to provide a larger match line voltage differential for match and mismatch conditions. Providing NV-CAM cells that have a larger sense margin can mitigate sensing issues for increased search operation reliability. One non-limiting example of an NV-CAM cell that employs MTJ differential sensing is a ten (10) transistor (10T)-four (4) MTJ (10T-4MTJ) NV-TCAM cell.

Abstract: Apparatus and methods for developing parallel networks. Parallel network design may comprise a general purpose language (GPC) code portion and a network description (ND) portion. GPL tools may be utilized in designing the network. The GPL tools may be configured to produce network specification language (NSL) engine adapted to generate hardware optimized machine executable code corresponding to the network description. The developer may be enabled to describe a parameter of the network. The GPC portion may be automatically updated consistent with the network parameter value. The GPC byte code may be introspected by the NSL engine to provide the underlying source code that may be automatically reinterpreted to produce the hardware optimized machine code. The optimized machine code may be executed in parallel.

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.
