Thermal dissipation system for wearable electronic devices
A thermal dissipation system for wearable electronic devices transfers heat away from a housing enclosing a heat source and dissipates the heat through a region of the support assembly that is noncontiguous with the housing. The support assembly may be coupled to the housing to enable the housing to be worn by a user. Various regions of the support assembly have different thermal resistances between a thermal conduit and an ambient environment. The thermal resistances may decrease as the thermal conduit becomes farther away from the heat source. The variations in thermal resistances enable modulation of relative heat flux between the various regions. For example, heat may be internally routed through the wearable electronic device to be dissipated through a surface that a user does not typically touch during operation. |

Diversity based relay for wireless communications between a head-mounted display and a console
A head-mounted display (HMD) is wirelessly coupled to a console or a relay depending on the relative positions of the HMD, the console, and the relay.

Aggregator technology without usernames and passwords implemented in unified risk scoring
Techniques are described in which for a user to obtain access to or entitlement to objects or locations, such as for example a web application or entry into an accounting office, the system derives a unified risk score associated with the user. The computer compares the unified risk score against a set of rules to determine whether the unified risk score is greater than a particular threshold. Based on such determination, the computer can cause denial of access or entitlement for example by denying entry to the web application or transmitting a denied message to a system that controls the physical lock on the door to the accounting office. In generating the unified risk score, the computer retrieves the most up-to-date identity information about the user by signing on to an aggregator system using any supported login identity provider username and password or other authenticating credentials associated with the user. |

Lawful interception of encrypted communications
A method and apparatus for providing access to an encrypted communication between a sending node and a receiving node to a Law Enforcement Agency (LEA). A Key Management Server (KMS) function stores cryptographic information used to encrypt the communication at a database. The cryptographic information is associated with an identifier used to identify the encrypted communication between the sending node and the receiving node. The KMS receives a request for Lawful Interception, the request including an identity of a Lawful Interception target. The KMS uses the target identity to determine the identifier, and retrieves the cryptographic information associated with the identifier from the database. The cryptographic information can be used to decrypt the encrypted communication. The KMS then sends either information derived from the cryptographic information or a decrypted communication towards the LEA. This allows the LEA to obtain a decrypted version of the communication. |

Method and apparatus for routing between fibre channel fabrics
An interfabric link between two separate Fiber Channel fabrics so that devices in one fabric can communicate with devices in another fabric without requiring the merger of the two fabrics. The interfabric switch performs a conversion or a translation of device addresses in each fabric so that they are accessible to the other fabric. This translation is preferably done using a private to public loop address translation. In a first embodiment the external ports of the interfabric switch are configured as E_ports. A series of internal ports in each interfabric switch are joined together forming a series of virtual or logical switches. The virtual switches are then interconnected using private loops. The use of the private loop is enabled by the presence of translation logic which converts fabric addresses to loop addresses and back so that loop and fabric devices can communicate. Because each port can do this translation and the private loop addressing does not include domain or area information, the change in addresses between the fabrics is simplified. In a second embodiment the external ports are configured as NL_ports and the connections between the virtual switches are E_ports. Thus the private to public and public to private translations are done at the external ports rather than the internal ports as in the prior embodiment. The virtual switches in the interfabric switch match domains with their external counterparts so that the virtual switches effectively form their own fabric, connected to the other fabrics by the private loops. |

In one embodiment, the I/O client transmits the performance data to a central monitoring system which can generate a chart plotting the performance data overtime. Because the I/O client may generate the high resolution performance data only when an event rule indicates there is a performance issue, the amount of performance data transmitted to the central monitoring system can be reduced. |
