  • Publication number: 20230140979
    Abstract: Systems and methods for material processing using wafer scale waves of precisely controlled electrons in a DC plasma is presented. The anode and cathode of a DC plasma chamber are respectively connected to an adjustable DC voltage source and a DC current source. The anode potential is adjusted to shift a surface floating potential of a stage in a positive column of the DC plasma to a reference ground potential of the DC voltage/current sources. A conductive plate in a same region of the positive column opposite the stage is used to measure the surface floating potential of the stage. A signal generator referenced to the ground potential is capacitively coupled to the stage to control a surface potential at the stage for provision of kinetic energy to free electrons in the DC plasma.

A conductive plate in a same region of the positive column opposite the stage is used to measure the surface floating potential of the stage. A control loop can be activated throughout various processing steps to maintain the surface floating potential of the stage to the reference ground potential. A signal generator referenced to the ground potential is capacitively coupled to the stage to control a surface potential at the stage for provision of kinetic energy to free electrons in the DC plasma.

  • Patent number: 11343355
    Abstract: An application mapping procedure obtains and aggregates application mapping information from a plurality of machines in a distributed system. A first layer of application mapping information is generated, identifying application entry points, each comprising a machine and a process executed by the identified machine. An application map is initialized with the first layer of application mapping information. A plurality of iterations of a predefined map gathering operation are performed, each iteration adding a layer of application mapping information to the application map, thereby producing an application map of the distributed processing of one or more respective applications. Each iteration sends queries, via one or more linear communication orbits, to machines in the distributed system, and obtains from the machines information identifying entities that have participated in predefined communications with entities identified in a most recently generated or added layer of application mapping information.

  • Patent number: 10484365
    Abstract: A network security system that employs space-time separated and jointly-evolving relationships to provide fast network access control, efficient real-time forensics capabilities, and enhanced protection for at-rest data in the event of a network breach. The network security system allows, in part, functionality by which the system accepts a request by a user to access the data stored in the database, identifies a sequence of security agents to participate in authenticating and protecting the access of the data by the user, generates a sequence of pseudorandom IDs and space-time varying credentials, checks at each one of the security agents a corresponding one of the credentials, determines that the user is permitted to access the data using access control logs if all the security agents accept the corresponding credentials, and varies the credentials based on a space-time relationship.
