Abstract: A method for providing enhanced network access controls (eNAC) for a network includes utilizing a database having a plurality of MAB entries set to a default disabled state, connecting a non 802.1X capable device to the network using a MAC address as a unique identifier, utilizing a network switch to challenge the non 802.1X capable device, sending the MAC address of the device to a RADIUS client to authenticate against known records, processing a connection request from the non 802.1X capable device, upon validating the connection request, granting access to the non 802.1X capable device, utilizing a MAB rescue application to temporarily change the account status for the non 802.1X capable device to an enabled state, permitting endpoint authentication of the non 802.1X capable device while the account is enabled, and preventing rogue endpoints from accessing the network by disabling all MAB entries and new accounts on the network.

Abstract: An embodiment of the invention is directed to a microfabricated, silicon-based, Convection Enhanced Delivery (CED) device. The device comprises a silicon shank portion, at least one individual parylene channel disposed along at least a part of an entire length of the shank, wherein the channel has one or more dimensioned fluid exit ports disposed at one or more respective locations of the channel and a fluid (drug) input opening. The fluid input opening may be configured or adapted to be connected to a fluid reservoir and/or a pump and/or a meter and/or a valve or other suitable control device(s) or apparatus that supplies and/or delivers fluid (e.g., a drug) to the microfabricated device. The device may have multiple channels disposed side by side or in different surfaces of the device. The device may be rigid, or flexible, in which case a flexible device can be attached to a bio-degradable support scaffold that provides sufficient structural rigidity for insertion of the device into the target tissue.

Abstract: A communication system includes a hub, a repeater, and a remote. The hub is configured to adjust a transmission power of the remote depending on an external condition based on (i) a measured carrier-to-noise ratio CNHubsignal1 of data transmitted from the hub to the repeater and back to the hub using a first signal, (ii) a measured carrier-to-noise ratio CNHubsignal2 of data transmitted from the remote to the hub via the repeater using a second signal, (iii) a predetermined carrier-to-noise ratio CNHubSCPCCS of data transmitted from the hub to the repeater and back to the hub using the first signal under a clear sky condition, and (iv) a predetermined carrier-to-noise ratio CNHubTDMACS of data transmitted from a reference remote to the repeater and back to the hub using the second signal under a clear sky condition.

Abstract: A satellite communication system includes a hub, a repeater, a scheduling unit, and a remote. The scheduling unit is configured to synchronize a communication of the system based on an elapsed time between (i) an arrival at the remote of a downstream reference frame transmitted by the hub and retransmitted by the repeater, and (ii) an arrival at the remote of an upstream frame transmitted by the remote and retransmitted by the repeater.

Abstract: A remote, a communications system, and a method in which the remote communicates with another remote via a repeater and also communicates with a hub. The remote includes a transceiver configured to receive a signal from the another remote, a measuring unit configured to measure a first offset, and a calculation unit configured to calculate a frequency offset for the signal based on (i) the first offset measured at the measuring unit, and (ii) a second offset measured at the hub.

Abstract: A communication method for a communication network includes transmitting first control information for a first frame from a hub to a plurality of user nodes, and receiving first data bursts in the first frame from first and second user nodes according to the first control information. A start of the first frame from the first and second user nodes occurs simultaneously at the hub. The method also includes transmitting second control information, based on demand information received from the first and second nodes, for a second frame from the hub after transmitting the first control information, receiving second data bursts in the second frame according to the second control information, and receiving the second frame at the hub following the first frame.

The first data burst from each user node arrives simultaneously at the hub, and the second data burst from each user node arrives simultaneously at the hub. Further, the second data burst from each user node arrives immediately following the arrival of the first data burst from each user node.
