Abstract: A liquid-permeable brush roll may include a main body having a radial surface, a cavity having an open end, a stopper removably coupled to the main body at the open end of the cavity, and one or more weep holes defined in the radial surface of the main body and fluidly coupled to the cavity. The cavity extends within the main body and is configured to store a cleaning fluid therein.

Abstract: A color mixing light system comprises a pyramidal mirror assembly comprising three or more mirrors constructed and arranged in a pyramid structure and three or more color light sources. The pyramidal mirror assembly divides the light beams from the color light sources so that a first portion is reflected by the mirrors and a second portion extends beyond the mirrors to collectively form a multicolor pattern comprising plurality of overlapping color regions on a surface.

Abstract: A robotic cleaner for autonomously cleaning a cleaning surface. The cleaner may include an agitation module configured to directly agitate a forward edge of cleaning pad. According to another aspect the cleaning pad may have a rigid strip at a leading edge thereof for slidably engaging a channel in a wet cleaning module to removably couple the cleaning pad to the wet cleaning module. According to another aspect, the cleaner may include wheels having a gapless tread configuration.

Abstract: A color mixing light system comprises a pyramidal mirror assembly comprising three or more mirrors constructed and arranged in a pyramid structure and three or more color light sources. The pyramidal mirror assembly divides the light beams from the color light sources so that a first portion is reflected by the minors and a second portion extends beyond the minors to collectively form a multicolor pattern comprising plurality of overlapping color regions on a surface.

Abstract: A mouth operated input system that includes a controller and a mouth operated input device that is operably coupled to at least one device so as to provide input control thereof. The mouth operated input device includes a joystick module and an activation module operably coupled thereto. The activation module includes an activation module control board and further has mounted thereto a first actuator and a second actuator. The first actuator is mounted to be engaged by a user's mouth. The second actuator is mounted to the housing of the activation module and is configured as an optical switch. The activation module is movable in all directions so as to provide movement of the joystick operably coupled thereto. The controller of the present invention includes a database that stores input data from the joystick module and the first and second actuators. Multiple modes of operation are provided by the controller.
