摘要： A method and an apparatus in a first wireless station of a network transmitting to a second wireless station. The network uses multi-tone OFDM signals. The first station includes multiple antennas and a receive and a transmit signal path per antenna. Each receive signal path includes a discrete Fourier transformer determining the tones in a received signal, and each transmit signal path includes an inverse discrete Fourier transformer converting tones to a signal. The method includes determining channel estimates for each tone and each receive path while receiving from the second station, determining transmit weights to transmit to the second station, tone-by-tone weighting a signal for transmission to the second station to produce weighted tone sets for each transmit signal path, and transmitting the weighted tone sets. The first station is configured so that the weighting produces additive beamforming without the second station needing multiple antennas.

摘要： A connector for connecting two tubular members (1,2) having annular flanges (3,4) at their ends. The connector comprising an actuating ring (13) movable in the axial direction of the tubular members (1,2), a plurality of upper dogs (15) for engaging the flange (3) of the upper tubular member (1) and a corresponding plurality of lower dogs (17) for engaging the flange (4) of the lower tubular member (2). Each pair of upper (15) and lower (17) dogs are connected by a stud (24) and are axially separable providing a sealed cavity (22) between the dogs which is supplied, in use, with hydraulic fluid. In use, the supply of hydraulic fluid to the cavity (22) forces the upper (15) and lower (17) dogs apart to tension the stud, so that, when the dogs are moved adjacent to the upper and lower flanges (3,4) and the pressure in the cavities (22) is released, the tension in the stud will be released allowing the upper (15) and lower (17) dogs to slide back together and clamp the upper (3) and lower (4) flanges together.

摘要： A sealing assembly for sealing between two relatively rotatable cylindrical surfaces. The assembly comprises two seal parts (46, 48) disposed in a groove (40) in one of the surfaces so that one of said parts is disposed radially outwardly of the other. One (46) of the parts is movable axially relative to the other (48) to effect setting of the sealing assembly and the groove (40) and parts (46, 48) are so dimensioned that they become compressed between the surfaces during setting of the assembly. Adjacent surfaces of the seal parts (46, 48) may have inter-engaging profiles (55) which permit relative movement for setting the assembly, but resist movement in the opposite direction.

摘要： In an example embodiment, packet encapsulation is employed to facilitate bridging between bridge ports that do not reflect frames (such as 802.1 compatible bridge ports) and bridge ports that do reflect frames (such as 802.11 compatible clients). Packets from a wireless access point may be sent twice, once with a predefined multicast address for processing by 802.11 clients contained in bridges, and once with the original destination address. In particular embodiments, additional means may be employed to minimize the circumstances where packets are duplicated.
