Abstract: Multiple, simultaneous enterprise promotions are enabled by an enterprise promotions application, the promotions definable to apply to a single location, a plurality of locations, or all of the enterprise's locations. The enterprise promotions application recieves data from the locations regarding patron activity, from which the system generates entries in one or more promotions according to each promotion's rules. For a promotion, patrons' entries can be activated for one or more drawings, wherein one or more winning entries are selected. The system also provides for the automatic, rules-based generation of comps and the management thereof.

Abstract: In the method, part of the liquid flow in a circuit is continuously withdrawn. A substantially constant head is established in the liquid drawn off, and at least some of this liquid is allowed to flow under gravity at a constant rate past a rotor rotated by a motor, so causing drag on the rotor in accordance with its viscosity. An operationing characteristic of the motor, such as its speed or the current which it draws, is monitored to provide an indication of the viscosity of the liquid. The constant head is established in one limb of a U-shaped chamber by means of a weir set at a predetermined height above the rotor, which is arranged in a downwardly directed passage surrounded annularly by the other limb of the chamber.
