Abstract: A method of operating a retail system which includes a plurality of self-service checkout terminals, a first remote supervisor terminal, and a second remote supervisor terminal includes the step of operating the first remote supervisor terminal such that the first remote supervisor terminal monitors operation of each of the plurality of self-service checkout terminals during a first period of time. The method also includes the step of maintaining the second remote supervisor terminal in an idle mode of operation such that the second remote supervisor terminal does not monitor operation of any of the plurality of self-service checkout terminals during the first period of time. Yet further, the method includes the step of operating the first remote supervisor terminal such that the first remote supervisor terminal monitors operation of a first group of the plurality of self-service checkout terminals during a second period of time.

Abstract: The invention provides disintegratable films containing a mixture of high molecular weight and low molecular weight water soluble components; and a pharmaceutically or cosmetically active ingredient. Optionally, the films contain a starch component, a glucose component, a filler, a plasticizer and/or humectant. The films are preferably in the form of a mucoadhesive monolayer having a thickness sufficient to rapidly disintegrate in the oral environment and release the active ingredient without undue discomfort to the oral mucosa. The monolayer can be cut to any desired size or shape to provide conveniently useable unit dosage forms for administration to oral or other mucosal surfaces for human pharmaceutical, cosmetic, or veterinary applications. The invention further provides methods of administering the film compositions by placing the composition into, for example, the oral cavity for a sufficient period of time to permit the film to disintegrate and release the active ingredient.

Abstract: A method of operating a checkout terminal includes the step of detecting generation of a peripheral-request control signal. The peripheral-request control signal including instructions for operating a retail peripheral device. The method also includes the step of generating a dispenser control signal in response to the detecting step. Moreover, the method includes the step of operating a currency dispenser so as to dispense an amount of change due to a customer in response to the dispenser control signal. The currency dispenser is distinct from the retail peripheral device. A checkout terminal is also disclosed.
