  • Patent number: 10305598
    Abstract: A method and apparatus for isolating an RF signal are provided. A first RF signal is received and passed to an input of a 90 degree hybrid. An output of the 90 degree hybrid is connected to a first waveguide and a second output is connected to a second waveguide of an optical modulator. A second RF signal is received and passed to an input of a second 90 degree hybrid. An output of the second 90 degree hybrid is connected to the second waveguide and a second output is connected to the first waveguide of the optical modulator. The optical modulator is biased to produce single side band optical outputs of the RF signals. The single side band optical outputs are passed to an optical notch filter to remove one of the side band outputs. The other of the side band optical outputs is converted to an electrical signal.

  • Patent number: 10306396
    Abstract: An improved methodology for binaural rendering of audio signals that are perceived by a user to originate from a real-world spatial location is disclosed. Embodiments enable personalized HRTF selection from among a data store containing a plurality of candidate HRTFs using an evaluation-based personalization strategy. One or more relational models personalize the selection. These relational models can relate candidate HRTFs to each other and a particular user to other users so that only a subset of the candidate HRTFs require evaluation. Candidate HRTFs can be evaluated according to one or more selection policies, and relational models can be updated based on actual responses from a user to virtual audio signals that are rendered by a candidate HRTF.

  • Patent number: 10305622
    Abstract: A system for transmitting a message, including an array of signal radiating elements for broadcasting signals that are unique one from another. One each of the unique signals is associated with one each of the radiating elements. One each of a set of transmitters is in electronic communication with one each of the radiating elements, and provides the associated unique signal to each of the radiating elements. A signal generating device receives the message from a message source and transforms the message into the unique signals. The unique signals, when broadcast, spatially interfere one with another such that the message is intelligibly receivable at only one location that is predetermined by the signal generating device, and is garbled at all other locations.

  • Patent number: 10276740
    Abstract: A method for forming a photon absorbing layer. A substrate having a target surface is introduced into a controllable environment, and the pressure within the controllable environment is reduced. A first flux of a semiconductor material and a second flux of a dopant are simultaneously directed toward the target surface for a period of time, thereby producing a thickness of a substantially amorphous layer of the semiconductor material and dopant on the target surface.

  • Patent number: 10274377
    Abstract: A ladar device that has a linear frequency-modulated laser source that produces a primary beam. An optical shear generator spectrally shears the primary beam into no less than three sensing beams. An optical output delivers at least one of the sensing beams toward a target. The sensing beams reflect from the target to produce reflected beams. An optical receiver receives the reflected beams and produces reflected beam signals corresponding to characteristics of the reflected beams. A processor receives the reflected beam signals and produces a deviation matrix, without the use of a local oscillator. The deviation matrix is used to produce a reconstruction of the target, which is output on an electrical signal output.

  • Patent number: 10276999
    Abstract: An optically pumped, flowing gas, alkali metal laser includes a gas passageway transporting an alkali metal vapor and a hydrocarbon buffer gas, and a laser propagation passageway intersects the gas passageway and forms a main cell at the intersection. A pump laser is directed into the main cell and produces a main laser beam in the laser propagation passageway. The flowing hydrocarbon buffer gas is disposed in the main cell with a density to induce spin-orbit relaxation in the alkali metal vapor. At least one window is disposed in the laser propagation passageway, and the window is protected from deposits of alkali metal or carbon by a heated leading edge in the laser propagation passageway that re-vaporizes alkali metal and returns it to the gas passageway via a convective gas flow. The window is further protected by a cold block that liquefies alkali metal and by a colder block that solidifies alkali metal in the laser propagation passageway.

  • Patent number: 10277316
    Abstract: A communications headset system and method of use utilizing first and second headsets with integrated hearing protection for enabling users to wirelessly communicate when the hearing protection is engaged. Each headset is configured for placement onto a user's head and includes hearing protection cups that engage a user's ears and attenuate incoming sound waves external to the headset. The headsets include a first optical receiver that detects a light signal within a first receiving field-of-view and generates an incoming electrical signal corresponding to the light signal. A speaker converts the incoming electrical signal to an incoming audio signal, and then outputs the incoming audio signal as sound waves. A microphone converts outgoing sound waves to an outgoing electrical signal. An optical transmitter converts the outgoing electrical signal to one or more light signals and then broadcasts the one or more light signals within a broadcast field-of-view and a broadcast range.

  • Patent number: 10267684
    Abstract: An apparatus, system, and method to characterize a focal plane array. The apparatus includes a speckle field source to generate and emit a plurality of uniform speckle fields, a diamond-shape aperture, and a pedestal to mount the focal plane array at a predetermined distance from the aperture. The diamond-shape aperture shapes the uniform speckle fields from the speckle field source so that the uniform speckle fields have a desired power spectral density at the focal plane array. The desired power spectral density has recoverable aliased regions out to two times the Nyquist frequency of the focal plane array. The system includes a controller to characterize, by computing a modulation transfer function, the focal plane array based on the desired power spectral density of the uniform speckle fields impinging on the focal plane array.
