  • Patent number: 10356064
    Abstract: Disclosed herein are systems and methods for distributed key management. A first communications node may join a network. The first communications node may receive a white list generated by a central authority. The white list may include criteria for selecting a master communications node that may generate and distribute a cryptographic key for the network. The white list may also identify one or more communications nodes authorized to receive the generated cryptographic key. Responsive to detecting a second communications node joining the network, the first communications node may determine whether the second communications node is to be the master communications node for the network.

  • Patent number: 10353068
    Abstract: A weather radar system can be used as an airborne sensor for providing an image on an electronic display during low visibility offshore IFR operations (e.g. for a helicopter approach to an offshore platform, such as, a petroleum rig or other structure). The weather radar sensed image is representative of the external surroundings of the maritime environment associated with radar returns received by the weather radar system. Beam sharpening technology produces higher angular resolution of the sensed objects in the radar image which reduces the interpreted azimuth errors from the sensed radar image. Accordingly, beam sharpening technology advantageously allows object isolation of closely clustered offshore platforms and nearby objects. With operational credit provided to these capabilities, the minimal distance for obtaining visual reference with the target platform could be reduced, increasing the success rate of completing offshore operations in low visibility IFR conditions.

  • Patent number: 10348382
    Abstract: Systems and methods of preventing interception of radiofrequency (RF) signals can include a first transmitter device (cover signal generator) and a second transmitter device (protected signal generator). The first transmitter device may have a first set of antennae to transmit a first RF signal in plurality of directions. The first RF signal may have a first signal strength in a target direction less than in directions adjacent to the target direction. The second transmitter device may have a second set of antennae to transmit a second RF signal to a target receiver according to an interception prevention configuration. The interception prevention configuration may include having the target receiver located along the target direction and the second RF signal having a second signal strength greater than a detection threshold relative to the first signal strength along the target direction.

  • Patent number: 10345969
    Abstract: An emissive display unit for an avionics display system installable in an aircraft cockpit may incorporate a display substrate housing emissive devices and a sensor substrate bonded to the rear surface of the display substrate. The sensor substrate may include a network of touch sensors configured to receive touch commands applied to the front surface of the display substrate. The touch sensors of the sensor substrate may be connected to drive electronics via a network of interconnect traces routed behind the rear surface of the emissive display unit (i.e., the rear surface of the sensor substrate). The drive electronics may then display images on the front surface of the display substrate via the emissive devices, based on touch commands received through the touch sensors. The front or rear surface of the sensor substrate may include a fully or partially metallized layer to disperse heat from the emissive display unit.

  • Patent number: 10321310
    Abstract: A system and method are disclosed for use of a passive sensor within a mobile device as a separate authentication mechanism to exchange a secure key with a desired network. A network access point presents an encoded bit stream via an audio signal over an audio channel or a video signal within a video presentation. Each signal type is configured for reception by a passive sensor on the mobile device. This received information would be used to generate the private key within the mobile device for encrypting the wireless communication channel. Only mobile devices within audio or visual range of the presentation may be authenticated and thus securely connected to the network.

  • Patent number: 10308371
    Abstract: A system and related method for managing images generated by a combined vision system (CVS) and displayed by an aircraft via an onboard PFD HDD, HUD, or HWD includes combining sensor image streams of an enhanced vision system (EVS) with navigation and terrain symbology generated by a synthetic vision system (SVS) to optimize the useful information displayed at any given point. Areas corresponding to prescribed visual references (approach lighting, runways and runway markers) that must be identified via pure EVS under certain conditions may be excluded from the SVS visual channels so that only a pure EVS channel of the excluded areas is displayed. The CVS may include edge filtering to remove unimportant terrain features and emphasize ridgelines. The CVS may display a full field of view for all selected visual channels or sensors, and optionally indicate where fields of view overlap.

  • Patent number: 10299114
    Abstract: An apparatus and method for providing external bump-in-the-wire cryptographic capability to a legacy radio (which may or may not include embedded cryptography) includes an appliqué couplable to the legacy radio and to an intercom, handset, or other user device. The appliqué extracts and stores in memory radio status information from the legacy radio (channel information, cryptographic instructions, alarm conditions) by intercepting control signals, polling the legacy radio, or listening in on channels used by the legacy radio. If TSVCIS 2.1 or CMI-compatible encryption is required, the appliqué may encrypt or decrypt a message with the appropriate cryptographic keys based on the extracted radio status information. The appliqué may include a bump-in-the-wire device or a bump-in-the-connector device directly couplable to an intercom port of a vehicular mounted SINCGARS legacy radio.
