A method of controlling multiple lamps is applied to an illumination system, which includes an input interface, a signal transmitter, a plurality of signal receivers, a plurality of driving devices, and a plurality of lamps. The adhesive strip is removable from the surface and provides a mechanism for folding the adhesive back so that the adhesive is covered and not free to attach unintentionally to objects or surfaces after removal from the initial surface. Each receiving device calculates a redundancy requirement based on signal-to-noise ratio samples. Because the soil collection receptacle is spaced from the cyclone body as the guide member is lifted, only the soil collection receptacle can be independently separated from the cleaner body. In a modified form, an electromagnetic sensor is provided which measures an electromagnetic noise transmitted to the transducer and which removes the electromagnetic noise from an output of the transducer to produce a noiseless acoustic signal. Previous methods of determining differences between high level block diagram models derive differences through traversal of the block hierarchy which is complex and cannot compare differences between models created with third party design environments.
