| 20100016008 | PRIORITIZATION OF GROUP COMMUNICATIONS AT A WIRELESS COMMUNICATION DEVICE - An embodiment is directed to switching between server-arbitrated group communication sessions at an access terminal (AT) within a wireless communications system. The AT participates in a first group communication session when it receives an announce message announcing a second group communication session, acquires priority levels for the first and/or second group communication sessions and determines whether to switch between sessions based on the priority level(s). In another embodiment, the AT participates in a given processing task (e.g., a gaming session, a voice call, a group session, etc.) when it receives an alert that relates to a group communication session. If the alert is specially configured to force the given access terminal to drop the given processing task, the AT drops the given processing task irrespective of whether the AT later joins the announced group communication session. | 01-21-2010 |
| 20100246468 | REGULATING THE SCOPE OF SERVICE GEOGRAPHICALLY IN WIRELESS NETWORKS - In an embodiment, a network communication entity obtains a location associated with an access terminal that is attempting to participate in a communication service, determines whether the obtained location satisfies a relationship with a defined location region, the defined location region establishing a first level of service restriction for the communication service within the defined location region and establishing at least a second level of service restriction for the communication service outside of the defined location region, and restricts the access terminal in accordance with the first or second level of service restriction for the communication service based on the determination. The network communication entity may correspond to the access terminal, an access network or an application server. If the access terminal detects a current, imminent or future service restriction, the given access terminal can initiate handoff to another service mechanism and/or inform the user of the service restriction. | 09-30-2010 |
| 20100248742 | REGULATING THE SCOPE OF SERVICE GEOGRAPHICALLY IN WIRELESS NETWORKS BASED ON PRIORITY - A network communication entity (e.g., an access terminal, access network and/or application server) obtains a location associated with a given access terminal that is attempting to participate in a given communication service, obtains a priority level of the given access terminal, determines a given level of service restriction for the given access terminal's participation in the given communication service based on the obtained location and the obtained priority level and restricts the given access terminal's participation in the given communication service based on the given level of service restriction. In an example, the priority levels can be established such that low-priority access terminals obtain a first level of service restriction within a defined location region, and a second level of service restriction outside of the defined location region, whereas high-priority access terminals obtain the first level of service restriction both inside and outside of the defined location region. | 09-30-2010 |
| 20100248771 | SELECTIVELY ALLOCATING DATA CHANNEL RESOURCES TO WIRELESS COMMUNICATION DEVICES WITHIN A WIRELESS COMMUNICATIONS SYSTEM - In an embodiment, an access network (AN) receives a request to allocate a given data channel (e.g., a traffic channel (TCH), Quality-of-Service, an Internet Protocol (IP) address, etc.) to a given wireless communication device (e.g., a call originator, a call target, etc.). The AN determines whether the given data channel is available for allocation to the wireless communication device. If the AN determines the given data channel not to be available for allocation to the wireless communication device, the AN determines a priority score to be associated with the received request. The AN initiates one of a plurality of data channel acquisition procedures (e.g., a preemption procedure, a queuing procedure, etc.) if the determined priority score is above at least one priority score threshold, each of the plurality of data channel acquisition procedures configured to obtain the given data channel in order to service the received request. | 09-30-2010 |

| 20100052888 | INFORMATION DISPLAY SYSTEMS AND METHODS FOR HYBRID VEHICLES - Information display systems capable of iconically representing the components of a hybrid powertrain and method thereof. In operation, the information display systems indicate the specific powertrain components in the hybrid system that are active in various hybrid operational modes (e.g., electric launch, blended torque, etc.). In particular, active components are highlighted (i.e., increased intensity) by the display and non-active components are faded (i.e., decreased intensity). In one embodiment, the vehicle wheels are depicted with a static intensity in-between that of the active components and the non-active components. This allows the vehicle operator to clearly see which components are active during each hybrid system mode, and to gain a simplified picture of hybrid system behavior during normal operation at a glance. | 03-04-2010 |

In one example, the systems present information in a manner that allows the driver to maximize the time that the hybrid vehicle is able to operate in electric launch mode. One manner is employing a graphical display that generates visual indicators and easily understood graphical representations that display the actual fuel efficiency currently being achieved in comparison to the driver's application of the throttle. As a result, the driver may be able to modify driving habits in order to keep the hybrid vehicle in electric launch mode for as long as possible. | 03-04-2010 |

In accordance with one embodiment, a method is provided that presents scrollable graphical elements on a shared screen area. More specifically, the method includes assigning a priority level to scrollable graphical elements that convey vehicle readings on the graphical display. Then, the one or more scrollable graphical elements are rendered on the graphical display at locations that change locations periodically. When an abnormal vehicle reading is identified, the method dynamically assigns an enhanced priority level to the scrollable graphical element that is configured to convey the abnormal vehicle reading. If the scrollable graphical element is currently assigned an off-screen location, the method causes the scrollable graphical element to be rendered. | 08-25-2011 |

For instance, the application engines may be dynamically configured to any of a plurality of different vector processing instruction sets, such as a single-precision vector processing instruction set and a double-precision vector processing instruction set. The co-processor further comprises a common infrastructure that is common across all of the different personalities, such as an instruction decode infrastructure, memory management infrastructure, system interface infrastructure, and/or scalar processing unit (that has a base set of instructions). Thus, the personality of the co-processor can be dynamically modified (by reconfiguring one or more application engines of the co-processor), while the common infrastructure of the co-processor remains consistent across the various personalities. | 05-06-2010 |

Algorithms control the drop probability of packets entering the queuing structure. Instantaneous drop probabilities are obtained by comparing measured instantaneous queue size with calculated minimum and maximum queue sizes. Non-utilized common memory space is allocated simultaneously to all queues. Time averaged drop probabilities follow a traditional Weighted Random Early Discard mechanism. Algorithms are adapted to a multi-level QOS structure, floating point format, and hardware implementation. Packet flow from a router egress queuing structure into a single egress port tributary is controlled by an arbitration algorithm using a rate metering mechanism. The queuing structure is replicated for each egress tributary in the router system. | 09-02-2010 |
