Patents by Inventor Kevin Kellar

Kevin Kellar 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).

  • Publication number: 20220018624
    Abstract: The invention relates to quick acting interfaces that allow for easier transportation and maintenance of precision rifles. Embodiments include an interface with an engaging segment and a receiving segment that engage one another and lock together. The engaging segment may have a series of connective bearings that fit into indentations inside the receiving segment. Embodiments allow a firearm to be modulated such that a barrel of the firearm may be disassembled without the need of any specialized equipment and reassembled without impacting the firearm's accuracy or reliability. Embodiments are scalable such that multiple interfaces can be used to adjust the total length of the firearm barrel.

  • Patent number: 10393867
    Abstract: Methods and systems for determining true time delay from each receiving element of an ‘active electronically scanned array’ (AESA) or a phased array antenna. Embodiments of the invention can include electromagnetic EM elements, optical waveguides, and wavelength selective FGBs are collectively configured as a plurality of dual purpose elements that couples an EM field and uses an induced voltage to change an index of refraction of the optical waveguide's electro-optic (EO) material, where the EO material will also function as a dielectric in an antenna element, where the signals comprising optical signals propagate through EM element acting as phase delay elements, where the measuring system compares the reflected signals with a reference signal with no phase delay to determine said signals phase delay.

  • Publication number: 20060239477
    Abstract: In various embodiments, a speakerphone may comprise multiple (e.g., 16) microphones placed in a circular array around a central speaker. The microphones may be mounted vertically in the speakerphone with their respective diaphragms substantially parallel to the top surface of the speakerphone. The centrally mounted speaker may be coupled to a stiff internal speaker enclosure. The speaker enclosure may be made of a stiff, heavy material (e.g., a dense plastic) to prevent the speaker vibrations from excessively vibrating the speakerphone enclosure (which may affect the microphones). The speaker enclosure may also include a raised rim and ridges to increase its stiffness.
