  • Patent number: 8596506
    Abstract: An adapting apparatus for mounting an accessory equipment on a bicycle is disclosed. The adapting apparatus comprises: a base having a mounting mechanism, a securing mechanism and a lock; an adaptor detachably mounted to the mounting mechanism of the base, the adaptor having an adapting mechanism for connecting to an accessory equipment; and a securing member detachably connected to the base through the securing mechanism and fastened to a portion of a bicycle; wherein, the lock, the mounting mechanism and the adaptor being configured such that the adaptor can be detached from the mounting mechanism only when the lock is unlocked.

  • Patent number: 8065712
    Abstract: Methods and devices for qualifying a client machine to access a network, based on policies governing required protective measures, such as virus checking and operating system updates, are disclosed. A client machine must pass various checks to qualify for access. A client machine may be redirected to remediation resources that support efforts to bring the client machine into compliance with applicable network access requirements. A policy repository is updated regularly by vendors of protective measures. An administrator establishes user roles that are mapped to policy rule sets retrieved from the policy repository. The policy rule sets govern qualification of client machines for access to the network in accordance with the roles of the users of the machines. An access server is an intermediary between a client machine and the access manager. A client agent runs on the client machine and carries out checks, and reports the results via the access server to the access manager.

  • Patent number: 8005049
    Abstract: The present invention relates to methods and devices that support mobility of a client across a campus, particularly mobility across VLANs and subnets, while preserving the client's assigned IP address. Both layer 2 and layer 3 packets are supported. Mobility support most clearly applies to wireless clients, but could apply to other kinds of mobile connections, even to wired connections. A smart server is adapted to support multiple VLANs and to modify and redirect packets in sessions with a client that moves from one VLAN to another, preserving the client's assigned EP address. Two or more smart servers, in cooperation with a smart manger, modify packets and tunnel them between smart servers when a client that moves from one VLAN to another and from one smart server to another, again preserving the client's assigned IF address.
