  • Patent number: 11928128
    Abstract: A system for maintaining a meta-database including meta-data representing decentralized data from source databases, which cause inefficient selection of modeling data and/or variables. Each of source and meta-data interfaces communicate with the respective database(s). A key variable repository module operably couples the databases and includes an AI program with a scanner algorithm and a profiler algorithm. The scanner algorithm receives the source data from the source interface, compresses the data, and synchronizes the data with the meta-data using the meta-database interface. The profiler algorithm receives the meta-data from the meta-database interface, generates granular data types for the meta-data, determines variables indicative of the meta-data, generates variable probability distributions, produces variable associations, and modifies the meta-database to include the probability distributions and associations using the meta-data interface.

  • Patent number: 11923939
    Abstract: Multiple mobility sets are maintained for nodes of radio networks. The sets comprise information such as: transmit and receive point identities; cell identities; beam identities; frequency channels; channel bandwidth; and black lists. The sets may be defined at different levels, such as network and physical (PHY) level. A network mobility set, e.g., a new-radio (NR) mobility set may, be determined by the gNB, the cell, the UE, or another device. Multiple radio access network nodes and UEs may exchange mobility set information to achieve a distributed mobility solution. A UE may monitor its orientation relative to a TRP, e.g., via use of an onboard MEMS gyroscope, and alter its beamforming parameters in response to changes in orientation and/or changes in TRP connection strength. Cell selection and reselection for beam based networks may use Single Frequency Network (SFN) broadcast of initial access signals without beam sweeping.

  • Patent number: 11815783
    Abstract: A difference frequency generation optical transmitter and sum frequency generation optical receiver operating in the mid-infrared wavelength range for use in free space optical satellite communications are described. By using mid-infrared light, the transmitter/receiver can mitigate atmospheric scintillation, scattering, and other non-ideal optical effects in the communication channel. This is achieved through the use of nonlinear optical crystals designed for difference frequency generation in the case of the transmitter and sum frequency generation for the receiver. High-speed modulated communication signals can thus be frequency converted to the mid-infrared wavelength range by a relatively low cost, compact and high-power optical communication system.

  • Patent number: 11809028
    Abstract: A high-power electro-optic modulator (EOM) is formed to use specialized electrodes of a material selected to have a CTE that matches the CTE of the modulator's crystal. Providing CTE matching reduces the presence of stress-induced birefringence, which is known to cause unwanted modulation of the propagating optical signal. The specialized electrodes are preferably formed of a CuW metal matrix composite having a W/Cu ratio selected to create the matching CTE value. Advantageously, the CuW-based electrodes also exhibit a thermal conductivity about an order of magnitude greater than conventional electrode material (brass, Kovar) and thus provide additional thermal stability to the EOM's performance.
