  • Systems and methods for routing data using software-defined networks
    Patent number: 11916874
    Abstract: Provided in some embodiments are systems and methods for determining a data flow path including a plurality of network devices for routing data from a first network device to a second network device; determining for the network devices one or more flow rules that specify an input for receiving data, an output for outputting data, and a role tag indicative of a role of a network device, where the role tag for one or more flow rules for a first network device of the network devices indicates a source role; distributing, to the network devices, the one or more flow rules; determining malicious activity on the data flow path; determining that the first network device is a source based at least in part on the role tag for the first network device; and sending, to the first network device, a blocking flow rule to inhibit routing of malicious data.

  • Metal chelating agents for medical application
    Patent number: 5463030
    Abstract: The present invention relates to a new group of compounds (e.g., N,N"-bis(2,6-dimethylcarbaniloylmethylene diethylene triamino triacetic acid, N,N"-bis(pyridoxylamine)diethylene triamino triacetic acid) which can be used as metal chelating agents and can be complexed with paramagnetic metal atoms form new complexes with improved and unexpected stability which make them extremely useful as contrast agents in magnetic resonance imaging and other types of diagnostic imaging. The chelating agents and corresponding paramagnetic metal complexes are derivatives of diethylene triamino pentaacetic acid and triethylene tetraamino hexaacetic acid.
