  • Patent number: 7893731
    Abstract: A non-inverting AC/DC input buffer combines the desirable characteristics of an alternating current (AC) input buffer including low delay, high speed, and high input voltage swing range with the desirable characteristics of a direct current (DC) input buffer including stability, reliability, and ‘automatic’ high and low data setup. The AC/DC buffer includes logic to help prevent the DC input buffer from interfering with the AC input buffer until the DC input buffer has completed its operations on a transitioning input. The DC buffer is configured to enable the AC buffer to process low input voltage swings such as, for example, voltage swings less than the difference in power supply voltages.

  • Patent number: 7894412
    Abstract: An apparatus configured to acquire received signal strength intensities (RSSIs) for a wireless device from a plurality of access points (APs) located on a plurality floors. The apparatus is configured to determine which floor the wireless device is on by analyzing the RSSIs. In an example embodiment, the RSSIs are adjusted, and the adjusted RSSIs for each floor are summed. The floor with highest sum of adjusted RSSIs is determined to be the floor the wireless device is on. In an example embodiment, the floor that the wireless device is on is determined by calculating the probability that the wireless device is within the cell of each AP on the network, and combining the probabilities for each floor. Known RSSIs between APs can be employed for comparing measured RSSIs with the known RSSIs to determine the probability that the wireless device is within the cell of each AP.

  • Patent number: 7849217
    Abstract: A Mobile Ethernet Protocol that is used to logically extend a “home VLAN”, through an Ethernet/IP “campus network”, to mobile nodes on “foreign subnets”. The network architecture used for Mobile Ethernet is hierarchical and includes a Subnet Context Manager per subnet and a central Campus Context Manager. The protocol is generally based on the standard Mobile IPv4 protocol, but includes significant extensions to standard Mobile IP including using an 802 address as the permanent MN identifier, rather than an IP address, encapsulating and sending Ethernet frames through IP tunnels, and configuring a single Mobile Ethernet HA to provide access to multiple home VLANs wherein Home VLAN bindings for MNs are dynamically established. A MN does not need to be configured with a permanent IP address.

  • Patent number: 7844057
    Abstract: A method and system for handling roaming mobile nodes in a wireless network. The system uses a Subnet Context Manager to store current Network session keys, security policy and duration of the session (e.g. session timeout) for mobile nodes, which is established when the mobile node is initially authenticated. Pairwise transit keys are derived from the network session key. The Subnet Context Manager handles subsequent reassociation requests. When a mobile node roams to a new access point, the access point obtains the network session key from the Subnet Context Manager and validates the mobile node by computing a new pairwise transient key from the network session key.
