  • Patent number: 10412573
    Abstract: Embodiments of this application provide a near-field wireless communication service processing method performed at a first computing device. While running a social networking application, the first computing device listens to a near-field wireless communication signal broadcasted by a second computing device. After detecting the near-field wireless communication signal broadcasted by the second computing device, first computing device processes the near-field wireless communication signal to obtain identification information associated with the second computing device. The first computing device sends the identification information associated with the second computing device to a remote server supporting the social networking application and obtains a preset service page corresponding to the identification information associated with the second computing device from the server, and displays the preset service page within the social networking application on the first computing device.

  • Patent number: 10341802
    Abstract: Currently there is no simple and satisfying way to create 3D audio from existing 2D content. The conversion from 2D to 3D sound should spatially redistribute the sound from existing channels. From a multi-channel 2D audio input signal (x(k)(t)) a 3D sound representation is generated which includes an HOA representation Formula (I) and channel object signals Formula (II) scaled from channels of the 2D audio input signal. Additional signals Formula (III) placed in the 3D space are generated by scaling (21, 222; 41, 422; Formula (IV)) channels from the 2D audio input signal and by decorrelating (24, 25; 44, 45, 451; Formula (V)) a scaled version of a mix of channels from the 2D audio input signal, whereby spatial positions for the additional signals are predetermined. The additional signals Formula (III) are converted (27; 47) to a HOA representation Formula (I).

  • Publication number: 20190196024
    Abstract: The invention relates to a method carried out by a navigation satellite system (NSS) receiver or a processing entity receiving data therefrom, for estimating parameters useful to determine a position. The NSS receiver observes NSS signals from NSS satellites over multiple epochs. A filter, called “precise estimator”, is operated, which uses state variables, makes use of NSS signals observed by the NSS receiver, and computes its state variable values based on observations that are not derived from NSS signals observed by the NSS receiver. Seeding information is obtained, and a constrained solution, called “seeding- and ambiguity-constrained solution”, is computed by constraining the ambiguities of the precise estimator by the seeding information, by resolving the resulting ambiguities, and by constraining at least one of the other state variables of the precise estimator by the resolved ambiguities. A corresponding system is also disclosed.

  • Patent number: 10332308
    Abstract: One or more system, apparatus, method, and computer readable media is described below for automated data type precision control capable of improving rendering quality on a graphics processor. Perceptible rendering quality is dependent at least in part on number format precision (e.g., FP16 or FP32) employed for shader program variables. In accordance with embodiments, shader variables implemented in lower precision data formats are tracked during shader compile to identify those that might trigger a floating point overflow and/or underflow exception. For shaders including one or more such variable, resources are provided to automatically monitor overflow and/or underflow exceptions during shader execution. In further embodiments, shader code is automatically re-generated based, at least in part, upon occurrences of such exceptions, and an increased number format precision specified for one or more of the tracked shader variables.

  • Publication number: 20190188554
    Abstract: Embodiments provide systems and methods which facilitate optimization of a convolutional neural network (CNN). One embodiment provides for a non-transitory machine-readable medium storing instructions that cause one or more processors to perform operations comprising processing a trained convolutional neural network (CNN) to generate a processed CNN, the trained CNN having weights in a floating-point format. Processing the trained CNN includes quantizing the weights in the floating-point format to generate weights in an integer format. Quantizing the weights includes generating a quantization table to enable non-uniform quantization of the weights and quantizing the weights from the floating-point format to the integer format using the quantization table. The operations additionally comprise performing an inference operation utilizing the processed CNN with the integer format weights.
