| 20090261883 | Symmetric blocking transient voltage suppressor (TVS) using bipolar transistor base snatch - A symmetrical blocking transient voltage suppressing (TVS) circuit for suppressing a transient voltage includes an NPN transistor having a base electrically connected to a common source of two transistors whereby the base is tied to a terminal of a low potential in either a positive or a negative voltage transient. The two transistors are two substantially identical transistors for carrying out a substantially symmetrical bi-directional clamping a transient voltage. These two transistors further include a first and second MOSFET transistors having an electrically interconnected source. The first MOSFET transistor further includes a drain connected to a high potential terminal and a gate connected to the terminal of a low potential and the second MOSFET transistor further includes a drain connected to the terminal of a low potential terminal and a gate connected to the high potential terminal. | 10-22-2009 |

| 20100030906 | RE-ESTABLISHING A CONNECTION FOR AN APPLICATION LAYER VIA A SERVICE LAYER - A method and system for establishing a connection with a server after a connection has been broken is provided. A connection system in a service layer of a client detects that a connection between the client and the server has been broken. Upon detecting the broken connection, the connection system of the service layer automatically attempts to re-establish an application-level connection to the server. If the connection system can re-establish an application-level connection to the server, then it need not notify the application layer of the broken connection. | 02-04-2010 |

| 20090300158 | METHOD AND SYSTEM FOR SUPPORTING THE COMMUNICATION OF PRESENCE INFORMATION AMONG COMPUTING DEVICES OF A NETWORK - A method and system for aggregating presence information generated by multiple devices associated with a single user is presented. A server acting as a presence agent on behalf of a first user and the first user's computing device receives and responds to a subscription request generated by a computing device operated by a second user that wishes to be permitted as a watcher of the first user. If the server is not capable of acting as a presence agent, then the first user's computing device assumes the role of a presence agent. | 12-03-2009 |

| 20090177784 | END-POINT IDENTIFIERS IN SIP - A system and method for uniquely identifying an SIP device extends the SIP communications protocol with an end point identifier, carried for example in the header of an SIP transmission. The end point identifier is useful for routing, registration, subscription, and authentication. The end point (device) of a given user epid can be uniquely identified by creating a key from an epid and a user's address-of-record (URI). This in turn enables improved connection management and security association management when the connections/IP addresses are transient, such as when HTTPS tunneling is used. | 07-09-2009 |
