A method for programming a MLC memory is provided. The intelligent lighting control apparatus includes a multi-sensor unit including multiple sensors, the multi-sensor unit sensing motion of a person or an object within a set sensing area using at least one of the multiple sensors. The measuring transducer also includes an exciter mechanism, via which, during operation, the measuring tube and the counteroscillator are excitable to oscillations of opposite phase to one another. x art heaters on a rated per million Btu per hour basis, and is further susceptible to developing steady-state heat transfer thermal efficiencies exceeding 124 percent. A particularly preferred embodiment of the present invention provides a method for simultaneously determining concentrations of all three organic additives within a single experimental run by using a single analytical cell, while interactions between such additives are properly accounted for.
