| 20090285369 | EMERGENCY NOTIFICATION THROUGH RESERVED NETWORK COMMUNICATION CHANNELS - A network communication channel can be reserved for emergency notifications. The network communication channel can be a dedicated protocol, port or message identification mechanism that can be recognized by networking software and directed to an emergency notification system that can be operationally associated with an operating system of a computing device. The emergency notification system can cause the computing device to provide appropriate emergency notifications that seek to inform the user without providing detailed, directed instructions that risk being misleading. A centralized emergency notification server can initiate the communications on the reserved communication channel and can direct such communications to computing devices affected by the emergency, which can be selected based on network identifiers associated with affected physical regions. | 11-19-2009 |

| 20090252110 | METHOD AND APPARTUS FOR EXTENDED REVERSE DIRECTION GRANT IN A WIRELESS LOCAL AREA NETWORK (WLAN) - Methods and apparatus for extended reverse direction grant in a WLAN. In an aspect, a method includes transmitting data within a transmit interval to a plurality of the nodes, wherein the data comprises a first indicator. The method also includes receiving, in response to the first indicator, a data transmission from at least one of the nodes, wherein the data transmission was transmitted using a selected transmission resource and is received within the transmit interval. In an aspect, an apparatus includes a receiver to receive, within a time interval, first data over a common channel, the first data being decodable by other nodes. The apparatus also includes a controller to determine whether the first data comprises a first indicator, and a transmitter to transmit second data within the time interval using selected transmission resources, if the first data comprises the first indicator. | 10-08-2009 |
| 20090252143 | METHODS AND APPARATUS FOR DELAYED BLOCK ACKNOWLEDGEMENT IN A WIRELESS LOCAL AREA NETWORK (WLAN) - Methods and apparatus for delayed block acknowledgments in a WLAN. In an aspect, a method is provided for communication with one or more nodes. The method includes transmitting to the one or more nodes a block comprising data and a first bit indicating no acknowledgements for the data are to be transmitted from the one or more nodes. The method also includes determining whether a selected time location within a transmit time duration has been reached, wherein if the selected time location has been reached, transmitting to the one or more nodes a second bit indicating that the one or more nodes are to transmit one or more acknowledgements, respectively, for the data. The method also includes receiving at least one acknowledgment for the data within a remaining portion of the transmit time duration. | 10-08-2009 |

| 20080291858 | Power Saving Wireless Local Area Network Portable Device - A system and method are provided for controlling bandwidth allocation in a wireless local area network (wLAN). The method comprises: expressing device bandwidth allocations in terms of a time base; in response to expressing the bandwidth allocation in terms of a time base, monitoring network communications; and, measuring the allocated bandwidths. The method may further comprise: establishing polling schedules in response to expressing the bandwidth allocation in terms of a time base; and, de-energizing devices in response to the polling schedules. Expressing device bandwidth allocations in terms of a time base includes establishing: an inter-transmission opportunity (TXOP) interval; and, a TXOP jitter. These fields are supplied in the IEEE 802.11e transmit specification (TSPEC). Then, de-energizing devices in response to the polling schedule includes disengaging transmission and receiving functions in the minimum TXOP intervals between polling events, where the minimum TXOP interval is the inter-TXOP interval minus the TXOP jitter. | 11-27-2008 |

| 20090036346 | Fabric Conditioning Composition - An aqueous conditioning composition comprising: (i) a water-insoluble, non-ester, quaternary ammonium fabric conditioning agent having at least 2 alkyl and/or alkenyl groups of at least 12 carbon atoms, or an alkyl or alkenyl group having a chain length of at least 20 carbon atoms. (ii) a water-soluble quaternary ammonium cationic surfactant and (iii) perfume, at least a portion of which is encapsulated. The composition is made by a specific process which comprises adding the encapsulated perfume to water prior to the addition of the water-insoluble quaternary ammonium fabric conditioning agent and adding the water-soluble quaternary ammonium cationic surfactant after the addition of the water-insoluble quaternary ammonium fabric conditioning agent and any free perfume and at a temperature below the phase transition temperature of the composition. | 02-05-2009 |
