Lavatory system

A control system for use with a lavatory system having at least one wash station and at least one electrically operated fixture, the control system comprising:

• a detection system configured to monitor a sensing region for the presence of a user and generate a transmit a control signal;
• a fixture actuation system coupled to the detection system and configured to receive the control signal from the detection system and control a flow of a fluid through the fixture based upon the control signal;
• a power source selectively coupled to the detection system;
• and
• a power management system coupled to the power source to control the power provided to the detection system, the power management system comprising:
• a detector configured to monitor a level of ambient light near the lavatory by monitoring an output voltage of the power source, the power source comprising at least one photovoltaic cell configured to convert the ambient light into output power;
• and
• a switching device configured to electrically disconnect the power source from the detection system in response to the level of ambient light dropping below a predetermined ambient light level as indicated when the output voltage of the power source drops below a predetermined level.

A power supply system for a lavatory system having a control system for operating a fixture, the power supply system comprising:

• a power source configured to be electrically coupled to the control system and to provide an output voltage;
• and
• a power management system coupled to the power source, the power management system comprising:
• a detector configured to monitor a level of ambient light near the lavatory by monitoring the output voltage of the power source, the power source comprising at least one photovoltaic cell configured to convert the ambient light into output power;
• and
• a switch configured to electrically disconnect the power source from a detection system in response to the level of ambient light dropping below a predetermined ambient light level as indicated when the output voltage of the power source drops below a predetermined level, wherein the detection system comprises a sensor for monitoring a sensing region for the presence of a user and is configured to transmit a control signal to the control system, wherein the control signal is configured to cause the control system to control a flow of a fluid through the fixture based on the control signal.
