Abstract:
New polymer compositions based on poly(2,6-dimethyl-1,4-phenylene oxide) and other high-softening-temperature polymers are disclosed. These materials have a microphase domain structure that has an ionically-conductive phase and a phase with good mechanical strength and a high softening temperature. In one arrangement, the structural block has a softening temperature of about 210° C. These materials can be made with either homopolymers or with block copolymers.
Abstract:
The invention provides an anti-wind eccentric umbrella, comprising a shaft, a framework, an upper ring, a lower ring and a canopy, in which the framework is composed of ribs, stretchers and a main frame. The two ends on one side of a main frame that is cross-hinged by a first main brace and a second main brace through a main frame hinge axis are respectively hinged with the upper ring and the lower ring. The anti-wind eccentric umbrella comprises a rib vacant position and the rib vacant position and the ribs are distributed in 360°. The main frame is on the rib vacant position, the top notch is hinged with an auxiliary rib, the runner is hinged with an auxiliary stretcher and the auxiliary stretcher is at the rib vacant position at the outer side of that occupied by the main frame.
Abstract:
A communications system provides a robust and fast inter-base station handoff mechanism, e.g. for networks using Enhanced Base Stations (EBS) equipment. A method for connecting a mobile device to a destination base station in the wireless communications system, may include steps of receiving a mobile device measurement report, transferring context information from a serving base station to possible target base stations, and receiving admission control information from possible target base stations. A priority list of the possible target base stations is calculated and sent to the mobile device. The mobile device connects to one or more of possible target base stations according to the priority list. The method may also entail receiving a release message from one of the possible target base stations to which the mobile device has successfully established a wireless connection, to allow release of resources of the prior serving base station.
Abstract:
Disclosed is a method for a femtocell to reduce interference with an overlapping macrocell. The femtocell determines soft-frequency-reuse (“SFR”) information of the macrocell. From that information, the femtocell determines which frequency sub-channels are assigned by the macrocell for its cell-center users and which frequency sub-channels are assigned for cell-edge users. (Cell-edge users are given a higher transmission power profile in order to overcome potential interference with neighboring macrocells.) Then, the femtocell selects from the cell-center user frequency sub-channels for transmission to the femtocell's users. By transmitting on the cell-center user frequency sub-channels, the femtocell reduces interference with the overlapping macrocell. The femtocell continues to update its knowledge of the macrocell's SFR information and re-assigns frequency sub-channels as the SFR changes. If the macrocell detects that one of its cell-center users is “close enough” to the femtocell, then the macrocell re-assigns the cell-center user as a cell-edge user to overcome interference.

Abstract:
The present invention provides a method for transmitting relay link uplink feedback information, a relay station and a base station, and the method comprises: determining timing relationship for transmitting the uplink feedback information according to relay subframe configuration (S202); a relay station determining an uplink relay subframe for transmitting the uplink feedback information according to the timing relationship (S204), and transmitting the uplink feedback information via the uplink relay subframe (S206). The present invention ensures the reliability of downlink communication between the base station and the relay station, and the transmission of this feedback information would not cause effect on user equipment.
Abstract:
One or more devices determine uplink signal strength for a machine-to-machine (M2M) device using a wireless access network. The one or more devices identify a default uplink transmission mode that requires the M2M device to employ transmission time interval (TTI) bundling, when the uplink signal strength is below a particular threshold, and identify a default uplink transmission mode that requires the M2M device to not employ TTI bundling, when the uplink signal strength is not below the particular threshold. The one or more devices store, in a memory, the default transmission mode for the M2M device. The one or more devices retrieve, from the memory and during a wake-up time window associated with the M2M device, the default transmission mode for the M2M device and construct, for the M2M device, an uplink scheduling grant based on the stored default transmission mode.
Abstract:
This invention relates to process for preparing fluorinated dyes selected from the group consisting of compounds of the general formulae (I) and (III) and mixtures thereof by reacting the corresponding compounds which do not have R12 or R30 as substituents with compounds of the general formula R12A or R30A where A is selected from the group consisting of I and Br, the compounds obtained from said process and the use of these fluorinated dyes in electrophoretic displays.

Ghrelin O-acyltransferase (GOAT) is inhibited with designed small molecules. Methods comprise contacting the GOAT with an inhibitor and detecting a resultant inhibition.
Abstract:
A communications system for providing a user's mobile station (MS) with an Internet Protocol (IP) connectivity, has an IP network gateway for allocating an IP address to the MS to enable it to access an IP network. First and second base stations are respectively configured to support communications of the MS over first and second radio access networks using different radio access technologies. A first access gateway provides an interface between the IP network gateway and the first radio access network, whereas a second access gateway provides an interface between the IP network gateway and the second radio access network. A handover interface is provided between the first access gateway and the second access gateway for enabling the MS to switch between the first and second radio access networks with minimum latency.
