  • Patent number: 9979923
    Abstract: A system and method for video display aboard an aircraft, automobile, or other vehicle includes a housing and an assembly including a display screen partially or completely contained within the housing. When the display screen is impacted by an object or a passenger of the vehicle, brackets and support members absorb and dissipate impact energy such that the display screen is prevented from breakage or dislodgement due to absorbed energy. Instead, the display screen may absorb impact energy insufficient to break it but sufficient to direct or shift the display screen from its original position to a new position. The video display system may also include spring-loaded or actuated brackets to return the display screen to its original position after an impact, and sensors to alert a user to inspect, repair or replace the brackets, display screen, or other system components.

  • Patent number: 9977247
    Abstract: A display can be utilized with an image source. The display includes a collimator and a substrate waveguide. The substrate waveguide sees collimated light from the collimator at an input and provides the collimated light to an output. The collimated light travels from the input to the output within the substrate by total internal reflection. An input diffraction grating is disposed in a first area at the input and an output diffraction grating is disposed in a second area at the output. The second diffraction grating is matched to the first diffraction grating. A combiner alignment detector is not required due to the periscopic effect according to one embodiment.

  • Patent number: 9971724
    Abstract: A multicore processor system and a method of operating the system defines a processor partition (which may include one or more processor cores) as a network offload engine for a network connected to the processor system. Network operations requests from other cores or partitions of the processor system are forwarded to the network offload engine by a cross-platform inter-partition communications component including a relay task in the network offload engine for receiving network operations requests from network proxies in the other partitions. The network offload engine then controls access to network resources by the other cores or partitions and applications running thereon. A second or additional core or partition of the processor system may be similarly defined as a network offload engine for a second or additional network, receiving network operations requests from the other partitions through a similar system of relay task and network proxies.

  • Patent number: 9971444
    Abstract: Touch sensors with multiple electrically isolated touch regions are disclosed. A touch sensor may be electrically partitioned into a first touch region and a second touch region. The first touch region and the second touch region may be physically connected and electrically isolated from each other. The first touch region and the second touch region may each independently define an independently operable portion of the touch sensor such that a failure in one of the first touch region or the second touch region does not impair operations in another one of the first touch region or the second touch region. A touch sensor configured in this manner may be implemented as a standalone touch sensing device, or as a component of other devices such as electronic displays or the like.

  • Patent number: 9973515
    Abstract: A system and method is disclosed for identification and response to an unauthorized transmission to a networked critical system. The invention employs a pre-defined parameter which matches trusted sources with defined destinations to enable secure access to the networked critical system. Once the method receives a transmission to the destination, it filters the transmissions based on specific architecture constraints. Should the transmission survive, the method continues with a plurality of layers of system level checks to verify the source matches the pre-defined parameter of a trusted source. Should the transmission fail any of the layers of system level checks, the method provides an appropriate response. Once the transmission survives, the method continuously monitors the data stream for possible threats and allows access the transmission to reach the destination and the networked critical system.

  • Patent number: 9969503
    Abstract: A system and related methods for providing stall recovery guidance symbology via a head-up display (HUD) or similar avionics display element detects stall or near-stall conditions and provides symbology to guide the pilot through recovering from the stall by prioritizing pitch correction and disengagement of the autopilot system. Pitch correction symbology guides the pilot toward reducing the aircraft angle of attack and establishing level flight, while thrust recovery symbology helps the pilot control the application of thrust to avoid prolonging or reinstituting the stall. The system modifies the stall recovery symbology in response to detected changes in pitch, angle of attack, or airspeed. Once level flight has been established and stall conditions are no longer present, the system may transition out of stall recovery mode to regular inflight symbology.

  • Patent number: 9965315
    Abstract: A system and related method for guest OS loading in a multi-core processing environment optimizes the startup process by loading a hypervisor runtime image to an allocated memory location, from which the processing cores individually activate and execute the runtime image rather than reloading the runtime image. For guest operating systems executing across multiple processing cores, a single core may load the associated guest OS image to allocated memory space in the system RAM. The remaining cores on which that guest OS is configured to execute may then copy the loaded guest OS image to their own respective allocated system RAM, and execute the copied guest OS images therefrom.
