    摘要: A method includes obtaining data to be transmitted wirelessly and detecting if any transmitting devices having a higher priority are currently using at least one of multiple wireless channels. The method also includes transmitting the data wirelessly over the multiple wireless channels in a first specified manner when no transmitting devices having the higher priority are detected. The method further includes transmitting at least a portion of the data wirelessly over the multiple wireless channels in a second specified manner when at least one transmitting device having the higher priority is detected. The data could normally be transmitted using OFDM. When a higher-priority transmitting device is detected, at least a portion of the data could be transmitted using a reduced transmit power and a reduced constellation size and/or larger error correcting code. One or more wireless channels associated with one of two quadrature components could also be suppressed.

    摘要: A mixer appliance having a base unit and a container unit. The base unit has a motor with a drive shaft. The container unit has a container and a rotor with a rotor shaft and a rotor element. A coupling arrangement connects the drive shaft and the rotor shaft when the container unit is connected to the base unit. A longitudinal axis extends through the drive shaft, coupling arrangement, and rotor shaft. The container unit has a bottom portion with a flexible diaphragm and a bearing member. The bearing member is supported by the flexible diaphragm, and the rotor shaft extends through the bearing member. The flexible diaphragm provides flexibility perpendicularly to the longitudinal axis, such that the bearing member is displaceable perpendicularly to the longitudinal axis to align the rotor shaft with the drive shaft along the longitudinal axis when the container unit is connected to the base unit.

    摘要: A vacuum cleaner dust separation unit having a cyclone chamber (113) and a dust collection chamber (115). The cyclone chamber (113) extends along a longitudinal axis (398), and has an air inlet (183), an air outlet (408), an inlet wall (396) between the air inlet (183) and the air outlet (408), and one or more air passages (404) through the inlet wall (396). The dust collection chamber (115) is adapted to receive dirt from the cyclone chamber (113). In one aspect, the inlet wall (396) comprises an elliptical wall that is located adjacent the air inlet (182) and angled relative to the longitudinal axis (398). In another aspect, the cyclone chamber (113) has an end wall (432) located opposite the inlet wall (396), and a dirt outlet (114) to the dust collection chamber (115) located adjacent the end wall (432), and the end wall (432) has a recessed portion (438) surrounding an extended portion (436) that protrudes into the cyclone chamber (113).
