  • ROBOTIC CLEANER WITH DUAL CLEANING ROLLERS
    Publication number: 20240090721
    Abstract: A robotic cleaner includes a housing, a suction conduit with an opening, and a leading roller mounted in front of a brush roll. An inter-roller air passageway may be defined between the leading roller and the brush roll wherein the lower portion of the leading roller is exposed to a flow path to the suction conduit and an upper portion of the leading roller is outside of the flow path. Optionally, a combing unit includes a plurality of combing protrusions extending into the leading roller and having leading edges not aligned with a center of the leading roller. Optionally, a sealing strip is located along a rear side of the opening and along a portion of left and right sides of the opening. The underside may define side edge vacuum passageways extending from the sides of the housing partially between the leading roller and the sealing strip towards the opening.

  • Fibre network proxy
    Patent number: 10855373
    Abstract: In an FTTDP optical fibre network, Distribution point units are reverse powered by customer premises equipment and therefore liable to power failure. When the distribution point unit loses power it is unavailable to respond to requests for performance or metric data. A persistent manager agent functions as a proxy for the distribution point unit, gathering metric and performance data from the distribution point unit using at least one EOC channel and handling requests for performance and metric data issued from other network devices. The persistent manager can also schedule downloads of firmware and configuration data to the distribution point unit.
