Abstract: A lightshow control system for generating a lightshow across a plurality of pixels or mobile devices comprises a controller configured to receive a lightshow operator's input and to generate a plurality of lightshow parameters. The system comprises a beacon transmitter in communication with the lightshow controller and configured to receive the lightshow parameters from the lightshow controller, encode the lightshow parameters on a beacon signal, and broadcast the beacon signal to the pixels, wherein each pixel is configured to receive and decode the beacon signal to perform one or more display actions. The decoded beacon signal includes reference timing information to facilitate synchronization of the pixels. The display actions may be based in part on the individual pixel location which is determined by the pixel based on TDOA multilateration and/or trilateration from distinct audio signals emitted by a plurality of speaker nodes.

Abstract: A diaphragm pump comprising a housing for receiving and securely holding a motor, the housing comprising an elongate portion having a closed end and an open end, the elongate portion being adapted to securely receive and house a motor; and a collar portion being provided at the open end of the elongate portion; a cover for the housing, the cover being adapted to engage with the housing; a diaphragm plate extending across the open end of the housing between the collar portion of the housing and the cover and being secured therebetween when the cover is engaged with the collar portion of the housing. The diaphragm pump also includes a wobble plate positioned within the collar portion of the housing.

Abstract: An apparatus is disclosed. The apparatus comprises a lean-burn internal combustion engine, engine management means and an exhaust system for treating exhaust gas of the engine. The exhaust system comprises a first oxidation catalyst disposed on a first honeycomb monolith substrate. The first oxidation catalyst comprises platinum supported on a first metal oxide support comprising at least one reducible oxide, and is substantially free of alkali metals and alkaline earth metals. The engine management means is arranged, when in use, intermittently to modulate the lambda composition of the exhaust gas entering the first oxidation catalyst to a rich lambda composition.
