An assembly for generating a continuous stream of smoke for food processing such as barbecue cooking includes a reusable cartridge holder for holding upright a disposable smoke generating cartridge. The invention provides a partition to a side of a fluid nozzle to form: a central cavity configured to define the fluid departing the surface into a central cavity vortex; and a side cavity adjacent the central cavity to define fluid escaping from the central cavity into a side vortex. A network resource matching a service unit in the service template may be found from the resource zone. In one embodiment, a Secondary Pilot Channel is transmitted at one of several selectable power levels to boost effectiveness of a phase reference, and is modulated to indicate the selected level. The system includes circuitry configured to: receive a steering angle command for a propulsion device of the marine vessel; receive a trim position of the propulsion device; and generate a steering actuator position command for the propulsion device based on the steering angle command and the trim position of the propulsion device. The image scanning device includes a document supporting plate and an optical scanning module movable in a longitudinal direction.
