Abstract: A pressure washer apparatus for cleaning a paved surface includes a motor driven zero-radius turn vehicle with a rotary sprayer positioned below a body of the vehicle. A pump and a reservoir containing a fluid are coupled to the body. The pump is activatable to urge the fluid from the reservoir through the sprayer such that the fluid propels the sprayer to rotate and that the fluid is forced toward the paved surface to clean the paved surface.

Abstract: A measurement device, in particular an electromagnetic flow meter, for measuring a flow, of a flowing fluid, comprising a measurement tube having an outer tube and a liner lining an inside of the outer tube, and a measurement structure for measuring a property of a fluid flowing through the lined measurement tube during measurement operation, capable of detecting abrasion of the liner.

Abstract: A gaming system includes a gaming server operate under program control to regulate the progress of a game of chance, a player station capable of displaying a simulation of the game of chance, a communication network that provides communication between the gaming server and the player station, and a means by which the player can place a wager on an outcome of a turn of the game of chance. The outcome of the game of chance is determined by the gaming server as a function of a sequence of randomly generated binary variables. The player station displays the simulation of the game of chance as an animation of a multistage decision tree in which the number of stages is equal to the number of binary variables in the sequence of randomly generated binary variables.
