In a preferred embodiment, the nature of this product is as a showerhead primarily useful for enabling a water spray from a plumbing fitting. The linking mechanism’s first and second axles are disposed orthogonal to each other and are separated by the body member. The FM demodulator frequency-discriminates the RF signal, performs digital conversion of the discriminated RF signal, and outputs converted data. A microprocessor is connected to the sensor and uses the signal from the sensor to detect the position of the cassette flap. The compounds are of the Formula I: .
