  • Patent number: 11652488
    Abstract: Techniques are provided for phase coherent frequency synthesis. An embodiment includes a first phase accumulator to accumulate a frequency control word (FCW) at a clocked rate to produce a first digital phase signal representing phase data corresponding to phase points on a first sinusoidal waveform. The embodiment also includes a second phase accumulator to produce an incrementing reference count at the clocked rate and multiply it by the FCW to produce a second digital phase signal representing phase data corresponding to phase points on a second sinusoidal waveform. The multiplication is performed in response to change in the FCW. The embodiment further includes a multiplexer to select between the first and second digital phase signals based on completion of the multiplication. The embodiment also includes a phase-to-amplitude converter to generate digital amplitude data corresponding to the phase points on a sinusoidal waveform associated with the selected digital phase signal.

  • Patent number: 11652299
    Abstract: A tightly coupled dipole array is an egg-crate configuration defined by a plurality of electrically connected antenna unit cells. At least one of the unit cells utilizes a short or conductive element that shorts the common mode resonance. Shorting the common mode resonance in an intentional manner removes instances of the common mode resonance. To achieve the shorting of the common mode resonance, a conductive element is connected with one of the dipole arms and connected to the outer conductor of the feed or a ground plane. This creates a grounding loop that pushes the resonance out of the band of interest.

  • Patent number: 11651474
    Abstract: The system and method for super resolution processing at long standoff distances in real-time. The system collects a series of image frames and estimated the shift, rotation, and zoom parameters between each of the image frames. A matrix is generated and then an inversion is applied to the matrix to produce a super resolution image of an area of interest while mitigating the effect of any bad pixels on image quality. In some cases, the area of interest is user-defined and in some cases image chips are provided by tracking software. A fast steering mirror can be used to steer and/or dither the focal plane array.

  • 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.

  • 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.

  • 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.

  • Patent number: 11600910
    Abstract: The system for an antenna assembly for use on unmanned underwater vehicles (UUV). The antennas are low-cost, lightweight, single-use, and have a small form factor amenable to use on a micro-UUV. A central post and pivotally attached arms form an antenna (e.g., a monopole) that is lifted via an aerial, kite, or the like, when deployed from the UUV to extend the line of site of the antenna several meters above the surface of the water. In some cases, the antenna may be used on a number of UUVs in a swarm formation.
