Abstract: Methods, platform and receptacles, such as a composting and retail platform facilitating multipurpose use of receptacles, characterized in that the platform manages cat litter sales, uses multipurpose receptacles for shipping of cat litter, for composting, and for an additional use when filled and readied for composting.

Abstract: A universal track adaptor system having a shell including a portable device receiving surface arranged for receiving and detachably holding a portable electronic device, said shell further including a track facing surface, a plurality of wheels including a first wheel and a second wheel; a first track adaptor rotatably coupling said first wheel and said second wheel to said track facing surface, said first track adaptor having a specific range of motion, said first track adaptor including an adaptive mechanism operable to adjust a specific width between said first wheel and said second wheel through said specific range of motion, whereby said first wheel and said second wheel can be adapted to interface with a plurality of different sized tracks, as permitted by said specific range of motion.

Abstract: A method and apparatus for optical switching using light bullets is presented. In one embodiment, the invention is a switch. The switch is a multi-channel, optical switch to use light bullets as optical pulses. The switch includes a waveguide of a first material. The switch also includes a plurality of channels extending from the waveguide. Each channel of the plurality of channels is to provide an optical path suitable for transmission of the light bullets. Each channel is formed of a material other than the first material. A first subset of the light bullets are to propagate into a predetermined channel of the plurality of channels responsive to interaction with a second subset of the light bullets.

Abstract: A mobile air duct vacuum provides an efficient method for cleaning HVAC ductwork in nearly any location. Upper and lower sections of circular cross-section are removably connected defining an air passageway. Said upper section houses 1st, 2nd and 3rd stage filters for insuring that “dirty” air passing through the system is thoroughly cleaned. Said lower section houses an air directional unit, blower wheel and motor. The motor causes the blower wheel, having spaced blades, to rotate and draw air from within the subject ductwork and through the filters thereby effectuating the cleaning. Thereafter, the clean air passes through the air directional unit into the blower wheel where it is re-directed to the surrounding environment through vents in the lower section. Wheels and a handle provide for a mobile air duct vacuum. To facilitate transportation of the vacuum the upper section and lower section can be readily disjoined.
