The invention provides a toroidal intersecting vane machine incorporating intersecting rotors to form primary and secondary chambers whose porting configurations minimize friction and maximize efficiency. The conveyor consists of a vacuum box under a vacuum effect, having at least one perforation extending lane-like in the direction of conveyance of the conveyor. In one variant, the user apparatus can communicate wirelessly with other user mobile devices to receive location information, and cause provision of the desired services at the received location. The semiconductor chips are mounted over the same die pad.
