  • Patent number: 11354312
    Abstract: A federated database-management system receives an SQL query or other type of data-access request. The federated system's host DBMS parses, rewrites, and optimizes the request into an optimal data-access plan, then determines which portions of the plan require access to data stored on the federated systems' remote databases. The federated host partitions the plan into subplans that each represent instructions of the original data-access request that were directed to a corresponding remote database of the federated DBMS. Each subplan is then transmitted to its corresponding remote database, which directly executes the subplan and returns results to the host. If necessary, a subplan is translated from an original generic access-plan format into a database-specific format required by its corresponding remote database.

  • Publication number: 20220115832
    Abstract: A system and method for safe use of an optics assembly with an external light source and an optically coupled optics module is disclosed. The system includes an external light module emitting a continuous wave laser through an output port. An optics module has an input port and a memory. The optics module generates a modulated optical signal. The memory stores the power level of the continuous wave laser signal received by the optics module. An optical jumper is provided for coupling the output port with the input port. A communication bus is coupled between a controller and the external light source module. The controller sets the external light source at a low power level and transitions the external light source to a high power level when the stored power level of the continuous wave laser signal received by the optics module exceeds a predetermined level.
