  • Patent number: 9712493
    Abstract: The inventive system includes a host, a network including a security gateway, and a public application. Established are an access session between the network and the host and an application session between the public application and the network. An application session record is created for the application session, and includes the user's public user identity used to access the public application, the user's private user identity used to access the network, a host identity, and an application session time. To determine the private user identity for the application session, the security gateway sends a query with the host identity and the application session time. These are compared with the host identity and access session time in an access session record, if they match, then the private user identity in the access session record is returned, and it is stored as the private user identity in the application session record.

  • Patent number: 9674644
    Abstract: A method and system detect directionality between two objects by measuring angles of signals incident on antenna arrays on at least one side to determine angle of incidence. The methods utilize Bluetooth Low Energy communications for both the control protocol and for providing updated information for deriving directionality. Directionality information is broadcast on selected BLE advertising or data channels, or broadcast using a hopping pattern over the BLE data channels, both at a specific interval duty cycle. If a hopping pattern is selected to transmit directionality information, then anchor information is simultaneously broadcast on the BLE advertising or data channels at a different, asynchronous duty cycle. In additional embodiments, signals incident on antenna arrays located on both target and tracking sides are used to determine angle of incidence, separate antennas are combined to form new antennas and antenna models are used to anticipate known antenna structure responses.

  • Publication number: 20160293386
    Abstract: A processing method and system are provided for processing a substrate with a plasma in the presence of an electro-negative gas. A processing gas is injected into a processing chamber. The gas includes a high electron affinity gas species. A surface is provided in the plasma chamber onto which the gas species has a tendency to chemisorb. The gas species is exposed to the surface, chemisorbed onto it, and the surface is exposed to energy that causes negative ions of the chemisorbed gas species, that interact in the plasma to release secondary electrons. A neutralizer grid may be provided to separate from the chamber a second chamber in which forms a low energy secondary plasma for processing the substrate that is dense in electrons and contains high energy neutrals of the gas species and high energy positive ions of processing gas. Pulsed energy may be used to excite plasma or bias the substrate. A hollow cathode source is also provided.

  • Publication number: 20160293389
    Abstract: A method and apparatus is provided for obtaining a low average electron energy flux onto a substrate in a processing chamber. A processing chamber includes a substrate support therein for chemical processing. An energy source induced plasma, and ion propelling means, directs energetic plasma electrons toward the substrate support. A dipole ring magnet field is applied perpendicular to the direction of ion travel, to effectively prevent electrons above an acceptable maximum energy level from reaching the substrate holder. Rotation of the dipole magnetic field reduces electron non-uniformities.
