    摘要： A coverage robot includes a drive configured to maneuver the robot as directed by a controller, a stasis indication wheel rotatable about a first axis perpendicular to a direction of forward travel, and a suspension supporting the wheel. The stasis indication wheel defines a first reflective portion and a second reflective portion. The second reflective portion is substantially less reflective than the first reflective portion. The suspension permits movement of the wheel in a direction other than rotation about the first axis. A signal emitter is disposed remotely from the wheel and positioned to direct a signal that sequentially is intercepted by the first and second reflective portions of the wheel. A signal receiver is positioned to receive the reflected signal by the rotating wheel. Communication between the emitter and the receiver is affected by rolling transitions between the first and second reflective portions during permitted movement of the wheel.

    摘要： A portable air cleaner including a housing defining an air inlet, an air outlet, and an air flow path therebetween, a centrifugal blower retained within the air flow path and operable to draw air through the inlet and a filter retained within the housing and disposed to transmit air circulating in the air flow path out of the outlet. Also included is a conveyor surrounding the blower and defining a scroll shaped passage having one end disposed to receive air from the blower and an opposite end disposed to discharge air into the filter, the conveyor being shaped and arranged to obstruct all rectilinear paths between the blower and the opposite end.
