  • CLOCK SYNCHRONIZATION FOR HIGH SPEED ASYNCHRONOUS SERIAL INTERFACES
    Publication number: 20230110448
    Abstract: The system and method for clock synchronization, or calibration, for use in high speed asynchronous serial interfaces. The system and method is automatic, on-line, and occurs in real-time. The process of synchronization may also be started by a user. The calibration scheme is a form of adaptive filtering using 8B10B encoding. Once idle traffic is 8B10B encoded it becomes a stream of K28.5 characters. These characters are used to tune a clock frequency. The process stops, and two devices are synchronized, when the number of idle K28.5 traffic samples are uniformly approximately identical for any of two successive sample intervals.

  • Asynchronous medium access control layer scheduler for directional networks
    Patent number: 11621925
    Abstract: An asynchronous medium access control layer scheduler increases efficiency for directional mesh networks by removing extra overhead in the time slots. The efficiency is increased by dividing time slots into sub-slots to allow for a receiving node to be offset by at least one sub-slot from the transmitting node. This enables the scheduler to more efficiently schedule operations for the nodes so that nodes can be performing other functions rather than waiting to receive a transmission or waiting after transmitting a transmission. The sub-slots may be sized to approximate the transmission propagation time or time of flight delay.

  • Command mixing for roll stabilized guidance kit on gyroscopically stabilized projectile
    Patent number: 11619473
    Abstract: The system and method of mixing pitch and roll commands from a flight control computer to produce fin deflections applied to as few as two fins to simultaneously produce both a rolling moment and a pitching moment. The system may be mechanical or digital where actuators can be linear or rotary, digital or analog. Deflections of the fins are generated which produce pitch and roll moments where addition of pitch and roll commands determines deflection commands to be sent to a first fin and subtraction of pitch and roll commands determines deflection commands to be sent to a second fin.
