  • Patent number: 10314083
    Abstract: An offloading controller for traffic offloading in a multi-radio-access-technology (RAT) network is described. The offloading controller includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to determine a channel utilization threshold based on a likelihood of packet collisions in a contention-based access network. The multi-RAT network comprises a centralized resource management network and the contention-based access network. The instructions are also executable to determine whether to offload one or more user equipments (UEs) on the contention-based access network to the centralized resource management network by comparing a current channel utilization of the contention-based access network and the channel utilization threshold.

  • Patent number: 10289924
    Abstract: A system and method are provided for the correction of a warped page image. The method first accepts a camera image of a page, creates a filtered edge map, and identifies text-likely regions. The filtered edge map and text-likely regions are projected into a polar coordinate system to determine page lines and warped image page curves. An adaptive two-dimensional (2D) ruled mesh piecewise planar approximation of a warped page surface is created. A three-dimensional (3D) model is created using the adaptive 2D ruled mesh and the estimate of the camera focal length estimate. Using the 3D model, a 2D target mesh is created for rectifying the image of the page. In one aspect, the adaptive 2D ruled mesh is projected onto a 3D warped page surface using the estimated camera focal length and an estimated surface normal of each planar strip from the adaptive 2D ruled mesh.

  • Patent number: 10274924
    Abstract: A system and method are presented for docking an actively stabilized platform. The platform includes an active stabilizing mechanism selectively engageable to orient the platform in at least a first axis of rotation. Once the docking procedure is initiated, a docking device engages the platform to prevent rotation in the first axis. When the docking device becomes fixedly engaged with the platform, the active stabilizing mechanism can be disengaged and the platform sustained in a first orientation defined by the first axis of rotation. In addition, the method may sustain the platform aligned in a first spatial position defined by at least two orthogonal axes. Similarly, if the docking device does not provide complete stability for the platform (i.e., engages the platform with a tolerance error), the active stabilizing mechanism can be partially engaged to minimize the tolerance error while minimizing power consumption.

  • Patent number: 10210602
    Abstract: A system and method are provided for normalizing a camera focal length. A perspective geometry estimator accepts a scanned image from a camera having an undefined focal length, and generates a normalized focal length estimate for the image. The normalized focal length estimate is compared to a normalized focal length density distribution. If the normalized focal length estimate meets a minimum threshold of probability, the normalized focal length estimate is selected and the image is processed using the selected normalized focal length estimate. If the normalized focal length estimate fails to meet the minimum threshold of probability, the image is processed using the highest probability prior normalized focal length from the normalized focal length density distribution.

  • Patent number: 10194856
    Abstract: Disclosed herein are a circuit and a method for the electrical data read-out of a large-area sensor flexible circuit. This circuit incorporates sensing elements of two types, and is therefore used for the measurement of two physical metrics associated with the etiology of pressure ulcers, one of which might be pressure. The flexible circuit is large enough to cover the area(s) of the human body. The flexible circuit comprises electrically of the following components: (a) a passive or active matrix array, and (b) its scanning/read-out circuitry. The matrix array (a) comprises further of (i) two electrodes for the sensing of pressure in each sensing element (sensel) of the array, and (ii) two electrodes for the sensing of another metric (temperature, moisture, pH, etc.) in each sensel. One electrode is shared (common) between the first (i) and the second (ii) sensor in the sensel.

  • Patent number: 10175361
    Abstract: A system and method are presented for using a two-dimensional (2D) LiDAR for three dimensional (3D) laser mapping. The 2D-LiDAR is mounted in a chassis. The method laser ranges a planar slice of the environment. Simultaneous with laser ranging the planar slice, the 2D LiDAR chassis is rotated about an axis to create a 3D laser mapping of at least a portion of the environment. More explicitly, the 2D LiDAR may include a laser ranger with a planar actuator, typically the combination of a laser and a rotating mirror. In addition, the 2D LiDAR chassis is mounted on a reciprocating actuator. Thus, the step of laser ranging the planar slice includes laser ranging the planar slice in response to the planar actuator. The step of rotating the 2D LiDAR chassis includes rotating the 2D LiDAR chassis around an axis parallel to the planar slice, in response to the reciprocating actuator.

  • Patent number: 10062152
    Abstract: A method for using a computing device for modifying a lower dynamic range image to a higher dynamic range image is described. According to the method, a lower dynamic range image including a plurality of pixels is analyzed by estimating a dark channel of the plurality of pixels of the lower dynamic range image. A histogram of the dark channel is analyzed by determining the brightest peak and a local minima of the histogram. Using the local minima of the histogram as a threshold for specular highlight determination, a binary mask for specular highlight determination is computed. A final mask is created by multiplying the luminance value of the lower dynamic range image with the binary mask. The final mask is then used to determine the higher dynamic range image. A system for converting a lower dynamic range image to a higher dynamic range image displays the higher dynamic range image on a higher dynamic range display.
