  • Patent number: 10775632
    Abstract: A system and method for augmented reality (AR) visor light security employs an optical shutter to mitigate illumination escaping from a see-through waveguide holographic AR display incorporated with a ballistic visor. Based on a security level of the environment, the user selects an auto or manual mode to command a full transmittance, partial transmittance, or full occlusion automatically set via ambient sensors within the system to remove glare and better view a contrast of AR images presented on the waveguide. In high security, the user relies solely on enhanced vision systems display on the waveguide for situational awareness and desire a full bi-directional occlusion of the optical shutter allowing zero emissions from the visor. An optical shutter sensor continuously measures the current level of occlusion to ensure it matches a commanded occlusion and if not, the system disables the display source and removes the occlusion.

  • Patent number: 10768370
    Abstract: A photonic N-to-one single-mode combiner is disclosed. In embodiments, the combiner receives multiple single-mode photonic inputs (e.g., via single-mode optical fibers) and combines the single-mode inputs into a multi-mode photonic output via photonic lantern. The multi-mode photonic output is converted via high-power, high-speed photodiode into an RF/electrical output which in turn drives an electro-optical modulator, modulating a second optical beam (e.g., a laser generated by a laser emitter of the combiner) to generate a single-mode photonic output signal.

  • Patent number: 10757111
    Abstract: A multilevel security fabric with address management units communicatively coupled to ports of a communication fabric and nodes of a multilevel security system are disclosed. The communication fabric facilitates communication between the nodes. An address management unit associated with a particular node extracts address maps contained in data requests associated with the particular node and regulates communication of that node any other nodes within the system across the communication fabric based on whether the extracted address maps are within an allowable address access range specified for the particular node. In the event that an extracted address map fails to fall within the allowable address access range, the address management unit may block the communication with the particular node. Accordingly, the address management unit may enforce multilevel communication across the communication fabric with high assurance.

  • Patent number: 10731959
    Abstract: A deployable active radar countermeasure or “smart chaff” device includes a flexible battery or length of reflective material for passive reflection of a surveillance radar signal. Metallized antenna elements printed onto the material receive the surveillance radar signals, and RF integrated circuitry bonded to the material generates active RF echo signals based on the frequency of the surveillance signal and the length of the material. Wirebond receiving paths include reconfigurable gain amplifiers and filters for adjusting the phase and amplitude of the echo signal, and transmit paths return the echo signal to the radar source via the antenna elements. Echo signals may combine with those of other such devices, having various lengths and associated frequencies, to simulate a false return associated with a particular aircraft or moving target (e.g., simulation of Doppler shift via offset echo frequencies).

  • Patent number: 10735127
    Abstract: A wavelength division multiplexing (WDM)-based photonic radar architecture is disclosed. The WDM-based photonic radar incorporates a WDM photonic input of N component wavelengths modulated by an IF-LFM input signal and its 90-degree phased counterpart. The modulated WDM photonic signal is split one branch sent to a photodetector for generation of an RF outbound signal and transmission of the signal, which is reflected by a target and received as an RF echo signal after a time delay. The other branch has each component wavelength time-adjusted by a second time delay for each wavelength. The resulting time-delayed WDM photonic signal is modulated again based on the received RF echo signal and split into wavelength selective channels. Filters in each channel extract two adjacent photonic signals converted to RF output signals by photodetectors. RF filters select a single RF signal for processing based on the closest difference between the two time delays.
