Abstract: An autonomous mobile robot includes a body, a drive supporting the body above a floor surface, a light-propagating plate positioned on the body and having a periphery defining a continuous loop, light sources each being positioned to direct light through a portion of the plate to a portion of the continuous loop, and a controller to selectively operate the light sources to provide a visual indicator of a status or service condition of the autonomous mobile robot. The drive is configured to maneuver the mobile robot about the floor surface.

Abstract: A compact and portable loudspeaker system operable in two configurations includes a driver array and a base unit having a bass enclosure and a dock. In an extended configuration, the driver array is supported by one or more extension legs between three to eight feet above the base unit where one of the extension legs is held by the dock. The base unit may be placed on a floor of a small to medium venue with the mid-to-high range driver array elevated near or above the elevation of an audience in the venue. In a compact configuration, the driver array is directly supported by the dock and the base unit and driver array may be placed on a table or desk in a classroom, conference room, or other such small to medium venue. The portable loudspeaker system may be transported in the compact configuration.

Abstract: The invention is directed to cushioning systems for athletic shoes that can be adjusted by a wearer. The systems include one or more cushioning inserts having anisotropic properties and are lockable in place in the shoe sole. The systems may also include structural support elements that provide additional stability and support to the wearer's foot. The wearer can adjust the degree of cushioning by rotating the insert within the shoe. The wearer can also remove the insert and replace the insert with a new and/or different insert.
