  • Publication number: 20200394639
    Abstract: A device and method for waveform transmission of transaction card data to a merchant point-of-sale device are provided. The device includes a memory device for storing data, a processor, and a transmitter. The device is programmed to receive transaction card data that mimics data stored within a magnetic stripe associated with a transaction card, convert the transaction card data to a first data file for storage within the memory device, transmit the first data file to the transmitter, and transmit a first waveform from the transmitter to the POS device, wherein the first waveform includes changes in a magnetic field that represent the transaction card data.

  • Publication number: 20190384304
    Abstract: In various examples, a deep learning solution for path detection is implemented to generate a more abstract definition of a drivable path without reliance on explicit lane-markings—by using a detection-based approach. Using approaches of the present disclosure, the identification of drivable paths may be possible in environments where conventional approaches are unreliable, or fail—such as where lane markings do not exist or are occluded. The deep learning solution may generate outputs that represent geometries for one or more drivable paths in an environment and confidence values corresponding to path types or classes that the geometries correspond. These outputs may be directly useable by an autonomous vehicle—such as an autonomous driving software stack—with minimal post-processing.

  • Patent number: 10474949
    Abstract: A method for classifying an object includes applying multiple confidence values to multiple objects. The method also includes determining a metric based on the multiple confidence values. The method further includes determining a classification of a first object from the multiple objects based on a knowledge-graph when the metric is above a threshold.

  • Patent number: 7380275
    Abstract: A secure processor assuring application software is executed securely, and assuring only authorized software is executed, monitored modes and secure modes of operation. The former executes application software transparently to that software. The latter verifies execution of the application software is authorized, performs any extraordinary services required by the application software, and verifies the processor has obtained rights to execute the content. The secure processor (1) appears hardware-identical to an ordinary processor, with the effect that application software written for ordinary processors can be executed on the secure processor without substantial change, (2) needs only a minimal degree of additional hardware over and above those portions appearing hardware-identical to an ordinary processor. The secure processor operates without substantial reduction in speed or other resources available to the application software.

  • Publication number: 20070195101
    Abstract: Video frame buffers are controlled using a sequence of new-frame-indicators (e.g., FLIP) and no-new-frame-indicators (e.g., NOFLIP) in a frame indicator queue that is accessed with each display refresh. Video samples are loaded into a chain of video frame buffers that is “rotated” during the vertical blanking signal of the display to swap an old frame buffer out for a new frame buffer. The rotations of the frame buffer chain are controlled based on the frame indicators in the frame indicator queue to present new video samples to the display in a regular pattern, thereby providing smooth video playback.

  • Publication number: 20070035752
    Abstract: Methods for mapping color data having at least one color associated therewith to an output device based on an input device profile and an output device profile, each profile having a tone curve and a color matrix, are provided. In one embodiment, the method includes receiving color data from an input device and determining whether the color data is in a linear space. If it is determined that the color data is not in a linear space, the method further includes applying the tone curve of the input device profile to the color data to convert it into a linear space. The method further includes converting the color(s) associated with the color data from the input linear space to an output linear space by applying the color matrix of the input device profile and the inverse color matrix of the output device profile to create color-converted image data.
