20090323640 | FAIR RESOURCE SHARING IN WIRELESS COMMUNICATIONS - Providing for fair resource sharing among wireless nodes in a wireless communication environment is described herein. By way of example, fairness can comprise establishing a set of resource sharing credits for wireless nodes. By expending credits, a node can borrow a resource of another node, to enable or enhance operation of the borrowing node. Credits for the borrowing node are decreased based on consumption of a shared resource, or credits for the lending node are increased based on such consumption, or both. Once an amount of credits expires, a node can be restricted from borrowing further resources until enough resources are lent to build up a suitable amount of credits. Accordingly, fairness can comprise correlating shared resource consumption with shared resource provisioning, to encourage participation in cooperative wireless communications. | 12-31-2009 |
20090325479 | RELAY ANTENNA INDEXING FOR SHARED ANTENNA COMMUNICATION - Providing for distributed processing for a set of wireless communication devices to implement distributed, multi-antenna communication via one or more of the devices is described herein. By way of example, a relay link can be established between one or more wireless transceivers. The link can be utilized to distribute an indexing parameter to a remote transceiver. The indexing parameter can be employed to identify a set of index-specific instructions configured for a particular wireless node of a network. Based on the instructions and indexing parameter, such transceiver can locally compute and transmit, or receive and decode, a stream of traffic data for the multi-antenna communication. Thus, for instance, a P-P link between UTs can be employed to implement increased throughput and reduced interference benefits of multi-antenna communication for unplanned configurations of mobile devices. | 12-31-2009 |

Alternatively, credentials classified as being of a non-privileged nature are made available for the push service. Authentication servers register with the ACPS to become consumers of the push service. A push server within the ACPS pushes non-privileged authentication credentials to registered authentication servers at predetermined intervals.

An authentication server can use a dynamic name service (DNS) lookup to find a specific authentication credentials push service (ACPS). | 10-31-2013 |
20130344865 | RLP Router - A practical inter-carrier roaming solution by way of a roaming location protocol (RLP) router that provides consistent location support across heterogeneous wireless network standards. The RLP router maintains connectivity to each location server in a roaming ecosystem, alleviating the need for an expensive and impractical mesh network of location servers. When a home location server (H-LS) determines it cannot locate a subscriber device because the subscriber device is roaming, the H-LS sends an RLP request to the RLP router. The RLP router then routes the RLP request to a serving location server (S-LS), which subsequently returns location information for the roaming subscriber device. The RLP router maintains mobile switching center ID (MSCID) to location based services (LBS) mappings for routing RLP requests. The RLP router may also maintain rough MSC-level positioning data for each MSCID to enable the RLP router to resolve certain location fixes without utilizing an S-LS. | 12-26-2013 |

When a SET capabilities parameter in a SUPL START message initiated by a requesting SET indicates that the SET supports a LTE positioning protocol (LPP), only, enhanced intelligent routing logic routes the SUPL session request to newly configured SUPL servers that support the LTE positioning protocol (LPP), only. Alternatively, when SET capabilities indicate that a requesting SET supports a radio resource location services protocol (RRLP), in addition to or in exclusion of a LPP, the intelligent router routes the session request message to SUPL servers that support the RRLP, in addition to or in exclusion of the LPP. Intelligent routing logic may also be enhanced to support SUPL intelligent off load (SI-OL) based on SET capabilities. | 03-12-2015 |

The reservoir can contain the substance. The aerosolizing mechanism can suspend a dose of the substance, as particulates for example, in a gas. The nozzle can include a lumen, an outer surface, and a distal end. The lumen can be sized to permit movement of the gas and particulates therethrough. The retaining member can be configured to be attached to the nozzle proximate the distal end of the nozzle, projecting laterally from the lumen of the nozzle, shaped to engage the ear and/or nostril, and can include a passage therethrough to allow passage of gas and to inhibit passage of at least some of the particulates. | 11-21-2013 |
20140174437 | DRY POWDER INHALER AND METHODS OF USE - Methods for reducing the risk of a thromboembolic event, and a related drug delivery system are provided. In some embodiments, a dose of acetylsalicylic acid can be provided in powder form to a patient using a dry powder inhaler. The dose can be effective to reduce a risk of a thromboembolic event in a patient. A dry powder inhaler used for the method can have a mouthpiece, a reservoir for receiving the dose of acetylsalicylic acid, and an actuation member for making available the dose of acetylsalicylic acid for inhalation by a patient through the mouthpiece. | 06-26-2014 |
