Abstract
A lavatory system having at least one wash station and at least one electrically operated fixture is disclosed. The lavatory system includes a control system for operating the at least one electrically operated fixture. The control system comprises a power supply system, a detection system, and a fixture actuation system. According to one embodiment, the detection system comprises a processor, a sensor configured to detect a user within a sensing region, and a sampling circuit configured to store a signal from the sensor that is used by the processor to activate the fixture. According to another embodiment, the power supply system includes a power source providing an output voltage for operating components of the control system, a detector monitoring the output voltage, and a switch for electrically disconnecting the power source from the components of the control system if the output voltage drops below a predetermined level. According to one embodiment, the power source is at least one photovoltaic cell coupled to the lavatory system.
