  • Patent number: 10382354
    Abstract: A transmission control protocol system includes a computer readable medium including instructions configured to cause processing electronics to, for each accepted frame of a plurality of accepted frames, determine an available bandwidth, send a first frame based on the available bandwidth being sufficient to send the first frame or delay the first frame by storing the first frame and a characteristic of the first frame, determine whether the delayed first frame and a received second frame are identical, and either one of: (i) send the delayed first frame and drop the second frame in response to the delayed first frame and the second frame being identical; and (ii) send the delayed first frame and delay the second frame by storing the second frame and storing a characteristic of the second frame in response to the first frame and the second frame being different.

  • Patent number: 10376198
    Abstract: An on aircraft computer system records and analyzes biometric data to identify indicia of impaired performance, such as pilot fatigue, attention tunneling, or cognitive overload. Such impairment is identified by alterations in pilot gaze or eye movement, head movement, facial parameters, eye lid position, heart rate, breathing, or brain wave patterns. Appropriate corrective action is applied based on the type of impaired performance identified, including altering a level of automation, contacting a ground dispatcher or ground pilot, or contacting a co-pilot or other crew member. Biometric data is continuously logged and correlated with data from other avionics systems to refine formulas relating biometric data to states of alertness and crew rest procedures.

  • Patent number: 10372901
    Abstract: Segregated cores or virtual processors within a processor establish at least two separate encryption paths via software virtualization. Guest operating systems and encryption applications operate on input data with an enforced level of synchronicity. Output is compared to determine if each encryption path arrives at the same encrypted output. If the outputs are identical, the encrypted data is passed on; if not, an error report is generated. No individual vulnerability may produce a single point of failure to produce erroneously encrypted or unencrypted output.
