Abstract: A method includes receiving, at a device operating in a first mode, a communication including a status indicator from a plurality of sensing devices, and storing the indicators in a memory. Operating in the first mode, a first input that includes a first actuation duration is received via a button, and the device is configured to operate in a second mode. The first actuation duration is longer than a first duration and shorter than a second duration, where an input duration exceeding the second duration configures the device to operate in a third mode. Operating in the second mode, an indication of the respective status indicator is provided on an output device for each of the status indicators. Transitions between the indications occur responsive to toggle inputs via the button. A second input is received via the button, and the device is configured to operate in the first mode.

Abstract: 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).

Abstract: A method includes receiving a first wireless signal and demodulating data in the first wireless signal using a first demodulation technique. The method also includes receiving multiple second wireless signals simultaneously (where the second wireless signals interfere to produce an interfered signal) and demodulating data in the interfered signal using a second demodulation technique. The method could also include (i) determining that a single transmitter transmitted the first wireless signal and selecting the first demodulation technique in response and (ii) determining that multiple transmitters transmitted the second wireless signals and selecting the second demodulation technique in response. Determining that the single transmitter transmitted the first wireless signal could include determining that a fundamental frequency of the first wireless signal is below a threshold.

Abstract: A handheld vacuum cleaner housing with a frame element forming at least a portion of a handle and extending in a main handle direction. A through hole passes through and is encircled by the frame element, and is configured to receive one or more fingers of an operator. A top casing element is connected to the frame element and covers at least some of a top side of the frame element. A bottom casing element is connected to the frame element and covers at least some of the bottom side of the frame element. The frame element, top casing element and bottom casing element are arranged to form at least part of a vacuum source housing for accommodating at least a part of a vacuum source. A vacuum cleaner having a similar housing, as well as a detachable second housing having a debris compartment and nozzle, is also provided.

Abstract: 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.
