| 20080299019 | System and process for upgrading heavy hydrocarbons - A system and process for upgrading hydrocarbons such as heavy oils includes high temperature plasma reactor apparatus, in one or more vessels, into which the oils are introduced along with water, such as steam, to produce lighter hydrocarbon fractions, along with carbon monoxide and hydrogen, that flows to an additional stage where more hydrocarbons and water are introduced for further fractionating reactions facilitated by reaction of carbon monoxide and water to produce carbon dioxide and nascent, or prompt, free radicals of hydrogen. Heavy hydrocarbons upgraded can include heavy oils in the form of tar sands, oil shale, and oil residuals. The vessel or vessels can each contain a carbonaceous bed facilitating the described reactions and example embodiments include one vessel with the reactions performed in a single bed and, also, two vessels with the reactions performed in a carbonaceous bed portion in each vessel. | 12-04-2008 |

| 20100146130 | Methods and Apparatus for Providing Session Policy During a Registration of a Device - A method for a user agent to access a session policy in a network is provided. The method comprises the user agent sending a registration message to a first network node. The method further comprises the user agent receiving policy-related information from the first network node in a response to the registration message. The policy-related information is one of the session policy, a Uniform Resource Locator that points to the session policy, and a Policy-Contact header containing a policyContactURI for a policy document. | 06-10-2010 |
| 20100154030 | Methods and Apparatus for Providing Alternative Paths to Obtain Session Policy - A method for a user agent to access a session policy in a network is provided. The method comprises the user agent receiving in a header field of a response message a plurality of uniform resource identifiers (URIs) for a policy server, wherein each of the plurality of URIs uses a different policy channel protocol. | 06-17-2010 |
| 20100154031 | Methods and Apparatus for Providing Indirect Alternative Paths to Obtain Session Policy - A method for a user agent to access a session policy in a network is provided. The method comprises sending, from the user agent, a single session policy request to a single network component, the single network component contacting a plurality of network components, wherein sending the single session policy request to the single network component utilizes a lower layer protocol. The lower layer protocol is at least one of Extensible Authentication Protocol (EAP), Point to Point Protocol (PPP), and General Packet Radio Service (GPRS) Activate Packet Data Protocol (PDP) context. The method further comprises aggregating policy information and providing the aggregated policy information to the user agent. | 06-17-2010 |

| 20090003252 | SYSTEM AND METHOD FOR CONSERVING POWER FOR A WIRELESS DEVICE WHILE MAINTAINING A CONNECTION TO A NETWORK - The invention relates to a system and a method for selectively reducing power consumption of a communication device communicating with a network is provided. In the method, it comprises the following steps: de-activating at least one communication subsystem of the device during intervals when the device is placed in a power save mode; and while the device is in the power save mode the method re-activates the subsystem in two instances. For the first instance, the communication subsystem is re-activated in relation to a first connection condition, and is then de-activated after a first event. For the second instance, the subsystem is re-activated in relation to a second connection condition and is then de-activated after a second event. | 01-01-2009 |
| 20090003278 | SYSTEM AND METHOD OF COMMUNICATING WITH A FIRST AND SECOND NETWORK BY A COMMUNICATION DEVICE - The invention relates to a system and method for maintaining a first connection to a first network and a second connection to a second network by a communication device. The method comprises: conducting a first activity to maintain or establish the first connection in a series of spaced, timed segments, such that the segments represent a timeframe of an original activity that would span a continuous period that would cause a transmission conflict with the second connection; and conducting a second activity for the second network only between two of consecutive segments of the series of segments. The first network may be a 802.11-class network; the first activity may be a beacon scan for a channel of the 802.11-class network; the second network may be a Bluetooth network; and the second activity may be transmission of an Advanced Audio Distribution Profile data to a second device through the Bluetooth network. | 01-01-2009 |
| 20090279492 | Methods And Apparatus For Use In Facilitating Access To A Communication Service Via A WLAN Hotspot - A mobile communication device identifies and selects a wireless local area network (WLAN) available for communications in its coverage area. Automatically, without detecting any requests made by a user via a browser application. The mobile device initiates a request (e.g. an HTTP GET request) to a predetermined server site of a communication network which is outside of the WLAN. In response to initiating the request, the mobile device receives a response message via the WLAN and identifies, from the response message, whether the request to the predetermined server site has been redirected to a redirect server site. The WLAN may be a WLAN “hotspot,” where the redirect server site is a login server. The identifying may be performed by comparing content from the response message to predetermined content of the predetermined server site. In response to identifying that the request has been redirected, the mobile device causes an indication to be produced at its user interface. Access to a communication service (such as a “push”-data service) may be subsequently expediently obtained. | 11-12-2009 |
