  • Publication number: 20080091305
    Abstract: An autonomous coverage robot includes a drive system, a bump sensor, and a proximity sensor. The drive system is configured to maneuver the robot according to a heading (turn) setting and a speed setting. The bump sensor is responsive to a collision of the robot with an obstacle in a forward direction. A method of navigating an autonomous coverage robot with respect to an object on a floor includes the robot autonomously traversing the floor in a cleaning mode at a full cleaning speed. Upon sensing a proximity of the object forward of the robot, the robot reduces the cleaning speed to a reduced cleaning speed while continuing towards the object until the robot detects a contact with the object. Upon sensing contact with the object, the robot turns with respect to the object and cleans next to the object, optionally substantially at the reduced cleaning speed.

  • Publication number: 20080016631
    Abstract: A robot obstacle detection system including a robot housing which navigates with respect to a surface and a sensor subsystem aimed at the surface for detecting the surface. The sensor subsystem includes an emitter which emits a signal having a field of emission and a photon detector having a field of view which intersects the field of emission at a region. The subsystem detects the presence of an object proximate the mobile robot and determines a value of a signal corresponding to the object. It compares the value to a predetermined value, moves the mobile robot in response to the comparison, and updates the predetermined value upon the occurrence of an event.

  • Publication number: 20070234492
    Abstract: An autonomous coverage robot includes a chassis, a drive system to maneuver the robot, an edge cleaning head carried, and a controller. The controller is configured to monitor motor current associated with the edge cleaning head and to reverse bias the edge cleaning head motor in response to an elevated motor current, while continuing to maneuver the robot across the floor. In another aspect, an autonomous coverage robot includes a drive system, a bump sensor, and a proximity sensor. The drive system is configured to reduce a speed setting in response to a signal from the proximity sensor indicating detection of a potential obstacle in a forward direction, while continuing to advance the robot according to a heading setting. Furthermore, the drive system is configured to alter the heading setting in response to a signal received from the bump sensor indicating contact with an obstacle.

  • Publication number: 20050150912
    Abstract: An adapter is used to allow beer to be dispensed from a single keg to a plurality of containers simultaneously. The adapter includes a connector for attaching the adapter to the keg tap spout. It further includes a separator for dividing a fluid flow from the keg into a plurality of flows. A plurality of spigots are connected to the separator for controlling flows into the plurality of containers.

  • Patent number: 6249631
    Abstract: A method for preparing a fiber optic cable for a splice wherein a radial compressive strain is applied to the fiber optic cable and the fiber optic cable is cut adjacent to the applied radial compressive strain to create a splice end of the fiber optic cable having a convex bulb. A corresponding device for preparing a fiber optic cable for a splice comprises a cutting means for cutting a fiber optic cable into a waste end and a splice end and a collet for applying a radial compressive strain to the fiber optic cable adjacent to the cutting means of the tool.
