  • Publication number: 20190245166
    Abstract: A battery pack is provided for a mobile communication device, comprising a casing defining a cavity that conforms, at least partially, to the outer shape of the mobile communication device and one or more rechargeable power cells housed within the thickness of the casing. An internal interface engages a corresponding interface on the mobile communication device to provide power from the one or more rechargeable cells to the mobile communication device. An external interface is electrically coupled to the internal interface in order to transmit signals from the mobile communication device to an external device and may further serve to recharge the one or more rechargeable power cells. The battery pack may also serve as an extendible platform by providing additional integrated communication interfaces and/or processors that can be utilized by the mobile communication device to extend its communication and/or processing capabilities.

  • Publication number: 20190147340
    Abstract: A computer-based system trains a neural network by solving a double layer optimization problem. The system includes an input interface to receive an input to the neural network and labels of the input to the neural network; a processor to solve a double layer optimization to produce parameters of the neural network, and an output interface to output the parameters of the neural network. The double layer optimization includes an optimization of a first layer subject to an optimization of a second layer. The optimization of the first layer minimizes a difference between an output of the neural network processing the input and the labels of the input to the neural network, the optimization of the second layer minimizes a distance between a non-negative output vector of each layer and a corresponding input vector to each layer. The input vector of a current layer is a linear transformation of the non-negative output vector of the previous layer.

  • Patent number: 10234689
    Abstract: An optic to transform incident light emitted by a light source to form an irradiation pattern on a projection surface has a freeform surface formed by a union of an aspheric lens and a collection of Cartesian ovals. Each Cartesian oval is a lens focusing the incident light to a point and the collection of Cartesian ovals directs the incident light to a collection of points forming a border of the irradiation pattern. The aspheric lens is a portion of a refractive lens directing the incident light to form an interior of the irradiation pattern. The aspheric lens is combined with the collection of Cartesian ovals to form the union, such that each Cartesian oval shares a radiant focus of the refractive lens and makes a tangential contact with the surface of the aspheric lens at a single point.

  • Patent number: 9703915
    Abstract: A method determines a sequence for drilling holes in a workpiece according to a pattern by first partitioning the holes in the pattern into packets. A global sequence of the packets is determined by solving a global traveling salesman problem (TSP), and a local sequence of the holes in each packet is determined by solving a local TSP for each packet. Then, the local sequences of the holes are joined according to the global sequence of the packets to determine a complete sequence for drilling the holes.

  • Patent number: 9618912
    Abstract: A method controls an operation of a machine using a model predictive control (MPC). The method determine, in response to receiving a state of the operation of the machine, a dual solution of a dual parametric problem of a parametric form of the MPC using a parallel quadratic programming (PQP) rescaling iteratively a candidate dual solution of the dual parametric problem. The coefficients of the dual parametric problem include data representing dynamics of the machine and constraints on the operation of the machine. A parameter of the dual parametric problem includes the state of the operation of the machine. The method determines a primal solution of a primal problem of the MPC using the dual solution of the dual parametric problem.

  • Patent number: 9613443
    Abstract: A method for generating a representation of a polyline formed by a sequence of points determines an overcomplete set of geometric primitives that redundantly fit overlapping sections of the polyline. The overcomplete fitting is performed such that the set includes one or more types of geometric primitives, each fitted to a section of the polyline formed by a subset of the sequence of points. The method determines a local cost of each geometric primitive based on a combination of a fitting error and an encoding cost of the geometric primitive, and determines a join cost of each successive pair of adjacent primitives. Next, the method determines a combination of the geometric primitives forming a connected path along a length of the polyline such that a sum of the local costs of the geometric primitives and the join costs of adjacent primitives in the combination is optimized.

  • Patent number: 9513623
    Abstract: A method for generating a trajectory based on an input trajectory formed by points representing spatial coordinates for a numerically controlled (NC) process determines a plurality of sequences of the points and determines, for each sequence, local costs of each point in the input trajectory. Each sequence is formed by removing a unique combination of points from the input trajectory and the local cost of a point for a sequence is determined based on a spatial arrangement of the point with respect to at least some of points in the sequence. For each sequence, a sum of corresponding local costs of each point in the input trajectory is determines and the trajectory is determined based on an optimal sequence with an optimal value of the sum of the local costs.

  • Patent number: 9251302
    Abstract: A method for planning a radiation therapy treatment of a body represented by a volume of voxels determines a radiation dose matrix representing a spatial distribution of a radiation dose of beams of radiation irradiating the volume with homogeneous stopping power. The beams are collimated and are shifted copies of each other at each depth of the volume, and the spatial distribution is determined by calculating cumulative beam-axial doses in a single matrix-matrix multiplication and redistributing the cumulative beam-axial doses to all voxels in the volume using a convolution. Next, a set of correcting operations is applied to the radiation dose matrix to produce a cumulative voxel radiation dose of the volume. Each correcting operation is linear, independent from another correcting operation and has a transform.

  • Patent number: 9248525
    Abstract: Locations in a pattern of a part are evaluated to determine if the locations are interior or exterior to a feature of the pattern. The pattern is used to cut the feature from a material by a laser cutting machine. A location in the feature is rendered into an array stored in a memory so that a value stored at an address in the array corresponding to coordinates of the location is either odd or even as determined by a counting process of the rendering. Then, the location is identified as being interior if the value is odd, and as being exterior if the value is even. The rendering can use modified forms of either rasterization or ray casting.
