20100325641 | COMMON COMPONENT FRAMEWORK - A Common Component Framework (CCF) provides a container interface and a component interface for communication in a multi-tiered software application. Component context data may be transmitted to and from a container describing a current state of a component executing within the container. Context data may correspond to a specific entity (e.g., a financial entity such as a company or stock) identified by a user interacting with the component. The container may communicate the context data between different components to synchronize and coordinate component behavior, providing a more robust and coherent user experience. In addition to component context data, other information may be transmitted between containers and components such as properties, menu options, and data fields, supporting more complete integration of even web-based components into containers. | 12-23-2010 |

20130042332 | Device and method for inducing brain injury in animal test subjects - An apparatus and method for inflicting brain injury on a laboratory animal that employs a platform for supporting the laboratory animal. The platform defines an opening for positioning the head of the laboratory animal over the opening. A projectile is launched from a projectile launching device orientated below the opening of the platform. The projectile launching device has a means for propelling the projectile directly at and/or through the opening of said platform, thereby inflicting brain injury on the animal via either a pressure wave or concussive impact of the projectile. Without helmet, direct impact of the projectile results in severe traumatic brain injury. Use of helmet protects animals from skull fracture, subdural hematoma, intracerebral hemorrhage and contusion yet produces mild concussion-like pathology. | 02-14-2013 |

20130254631 | CONTENT DELIVERY SYSTEM WITH ALLOCATION OF SOURCE DATA AND REPAIR DATA AMONG HTTP SERVERS - Data objects are delivered over a packet-switched network and receivers receive encoded symbols, such as repair symbols, broadcast or multicast, with sufficient information to form requests for additional symbols as needed based on what source symbols or sub-symbols are needed or missing. The requests can be made in a unicast or request fashion. Requesting and broadcasting might be done by different entities. A broadcast server can generate and store repair symbols while a source server can store content in source form. A request can be a unicast HTTP byte-range request, such as a URL, starting position and length. Requests might be aligned with starting positions of files. A receiver can calculate starting and ending byte positions of symbols or sub-symbols in a file and get indications that conventional HTTP servers are usable for file repair. Repair servers can request broadcast of repair data when byte-range requests from multiple receivers overlap. | 09-26-2013 |

20120289179 | HOME NETWORK ROAMING MANAGEMENT FOR eCALL-ONLY SUBSCRIBERS - A Home Public Land Mobile Network (HPLMN) or home network immediately accepts a registration requests from “eCall-only” subscribers attempting to register with any Visitor Public Land Mobile Networks (VPLMNs) or roaming network. This avoids unnecessary delays in the establishment of an eCall (emergency call) that might be otherwise introduced by the home network's roaming registration management policy (RRMP) that otherwise would only permit registrations (and subsequent call servicing) by preferred roaming VPLMN partners and automatically reject registrations from non-preferred roaming networks (which may hinder or prevent timely completion of an eCall). | 11-15-2012 |
20120289180 | PROACTIVE PROBE BY eCALL-ONLY IN-VEHICLE SYSTEM - Proactive registration probes are conducted by an eCall-only IVS prior to an emergency to determine network availability and which available roaming networks a registration request will be approved by the home network. The results of this probing are stored and managed by the IVS. If no suitable roaming network can be found (or if only limited service is available, and this limited service cannot support an eCall), the IVS may notify the driver that the emergency call service may not be available. The frequency of the probing may be increased or decreased based on a variety of factors, including whether the IVS is currently receiving home network service, roaming network service, or no service, as well as whether the vehicle is moving and whether probing has previously been completed for a particular area (using location information, for example). | 11-15-2012 |
20120289181 | IN-VEHICLE EMERGENCY CALL SERVICE REGISTRATION AND CALL SETUP USING FOLLOW-ON REQUEST - A follow-on request is used in the registration request of an eCall-only mode in-vehicle system (IVS) to keep the connection alive between the registration and the emergency call setup in order to speed up the overall signaling process before sending eCall data for the eCall-only mode IVS. In this manner, two separate connections are not needed in order to perform the registration of the IVS on the mobile network and then the emergency call setup. Only one connection is used and maintained throughout registration and call setup processes. This speeds up the eCall emergency registration and call setup. In an implementation, the registration request with the follow-on request is provided only when the eCall-only IVS is activated for use in an emergency call (i.e., in an initial registration of the eCall-only IVS). | 11-15-2012 |
20120289182 | PRIORITY REGISTRATION FOR IN-VEHICLE EMERGENCY CALL SERVICE - An eCall is an emergency call that may (i) be initiated automatically by a wireless terminal due to a trigger event (e.g., a vehicle involved in an accident) or manually by a user and (ii) include additional data sent automatically by the terminal to a recipient entity, e.g., a Public Safety Answering Point (PSAP). Emergency setup signaling (e.g., an Emergency SETUP message) is used to give high priority to registering an eCall-only mode In-Vehicle System (IVS) on a mobile network. The IVS can get higher priority from the mobile network right after an eCall emergency is triggered at the IVS. When requesting a connection to the mobile network, the IVS can use an “emergency setup” message instead of a conventional “registration” message in order to register on the network. | 11-15-2012 |

The first node may send the control information in the header of multiple packets toward the second node. In one design, the control information may include congestion information indicative of traffic congestion at the first node. The congestion information may be sent using Explicit Congestion Notification (ECN) bits in the header of IP packets. The first node may send the control information with or without coding and for all packets or a specific data flow. The first node may also send a synchronization sequence prior to the control information. | 06-30-2011 |
