Kenneth Vavreck has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10495467
    Abstract: Techniques for determining a position of a mobile device using visible light communication signals are provided. An example device includes memory and a processor configured to in response to a determination that at least one first image of a plurality of images stored in the memory is of a modulated light signal transmitted by a light source and comprising coded information, determine a spatial location of a reference point of the light source based on the coded information, in response to a determination that at least one second image of the plurality of images is of an unmodulated light signal emanating from the light source, determine an image location of the reference point of the light source in the at least one second image, and determine a position of the mobile wireless communication device based on the image location of the reference point and the spatial location of the reference point.

  • Patent number: 9660727
    Abstract: Disclosed are methods, systems, devices, apparatus, computer-/processor-readable media, and other implementations, including a method to decode a visible light communication (VLC) signal by capturing images of a light source emitting a light modulated signal comprising a temporal sequence of symbols to determine decoded symbols and to further determine at least one codeword from a list of candidate codewords.

  • Publication number: 20120098942
    Abstract: At least a method and a system are described for providing frame rate conversion using parallax information. In a representative embodiment, the method comprises receiving a frame of stereoscopic video. The stereoscopic video comprises frames for displaying to a left eye and to a right eye. The method comprises computing displacements for a plurality of groups of pixels, wherein each of the groups corresponds to an object of a plurality of objects. The method further comprises using the plurality of displacements to position the plurality of groups within an interpolated frame.
