  • Patent number: 11617123
    Abstract: Airtime network policies for quarantined station network policies are stored in a database for application to quarantined stations. Quarantined stations are moved from a first VLAN to a quarantine VLAN with a dedicated BSSID on the Wi-Fi communication network. An RU airtime allocation module of the access point allocates airtime RUs for suppression of some or all transmissions from the quarantined stations. The airtime RU allocation module determines an amount of RUs for access to airtime on a Wi-Fi communications network, based on a network policy that limits an amount of airtime allowed by quarantined stations.

  • Patent number: 11611933
    Abstract: In a microcell environment, access points with a probe-if-assigned setting configured to delay probe responses to probe requests is registered and managed by a Wi-Fi controller. Probe requests are received and forwarded from at least two of the plurality of access points from a specific station attempting to connect to the Wi-Fi communication network. A Wi-Fi assignment module receives RSSI measurements from the at least two access points with respect to the specific access point, during a delay from the probe-if-assigned setting. A specific access point is assigned to the specific station for sending a probe response once a delay period expires.

  • Publication number: 20030005418
    Abstract: The present invention provides methods for facilitating the adaptation of shared data structures created in assembly language to differing memory models, compiler alignment constraints, and hardware alignment constraints. The use of these methods permits the assembler to create shared data structures that are transparently adapted to memory alignment differences introduced by the differing memory models and alignment constraints.

  • Patent number: 5827831
    Abstract: The oral delivery of many classes of drugs is facilitated by converting drugs having suitable functional groups to 1-O-alkyl-, 1-O-acyl-, 1-S-acyl, and 1-S-alkyl-sn- glycero-3-phosphate derivatives. The method confers the ability to be absorbed through the digestive tract to drugs that are not orally bioavailable in the non-derivatized state, and enhances the effectiveness of drugs that are poorly absorbed or rapidly eliminated. The method provides orally bioavailable lipid prodrugs of pharmaceutical compounds having diverse physiological activities, including anticancer and antiviral agents, anti-inflammatory agents, antihypertensives and antibiotics. Potency of the lipid prodrugs is comparable to that of the corresponding non-derivatized drugs.

  • Patent number: 5484809
    Abstract: The oral delivery of many classes of drugs is facilitated by converting drugs having suitable functional groups to 1-O-alkyl-, 1-O-acyl-, 1-S-acyl, and 1-S-alkyl-sn-glycero-3-phosphate derivatives. The method confers the ability to be absorbed through the digestive tract to drugs that are not orally bioavailable in the non-derivatized state, and enhances the effectiveness of drugs that are poorly absorbed or rapidly eliminated. The method provides orally bioavailable lipid prodrugs of zaxol and taxol-related compounds. Potency of the lipid prodrugs is comparable to that of the corresponding nonderivatized drugs. In a preferred embodiment, taxol or substituted taxol is covalently bound to a phospholipid.
