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 provided for selecting a three-dimensional model. An input image including an object can be obtained, and a pose of the object in the input image can be determined. One or more candidate three-dimensional models representing one or more objects in the determined pose can be obtained. From the one or more candidate three-dimensional models, a candidate three-dimensional model can be determined to represent the object in the input image.

Abstract: A fingerprint sensor is described that includes a thin protective cover layer on a sensor glass layer with receive circuitry between the thin protective cover layer and the sensor glass layer. In an implementation, a fingerprint sensor assembly includes a controller; a metal layer configured to be electrically coupled to the controller; a transmit layer electrically connected to the metal layer and the controller; a sensor glass layer, where the transmit layer is disposed on a first side of the sensor glass layer, and where the transmit layer is electrically coupled to the controller; a receive layer disposed on a second side of the sensor glass layer, where the receive layer is electrically coupled to the controller; and a protective cover layer disposed on the receive layer.

Abstract: Disclosed are a system, apparatus, and method for multiple client simultaneous localization and mapping. Tracking and mapping may be performed locally and independently by each of a plurality of clients. At configurable points in time map data may be sent to a server for stitching and fusion. In response to successful stitching and fusion to one or more maps known to the server, updated position and orientation information relative to the server's maps may be sent back to the clients. Clients may update their local map data with the received server location data. Clients may receive additional map data from the server, which can be used for extending their maps. Clients may send queries to the server for 3D maps, and the queries may include metadata.

Abstract: A user device receives an image stream from the user side of the user device and an image stream from a target side of the user device. The user device acquires a coordinate system for the user, acquires its own coordinate system, and relates the two coordinate systems to a global coordinate system. The user device then determines whether the user has moved and/or whether the user device has moved. Movement of the user and/or the user device is used as input modalities to control the user's interactions in the augmented reality environment.

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: 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.
