1. A lavatory comprising:
- at least one wash station;
at least one electrically operated fixture associated with the wash station;
a detection system comprising a sensor for monitoring a sensing region for the presence of a user and configured to generate and transmit a control signal;
a control 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 at least one electrically operated 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.

Abstract
A lavatory is provided. The lavatory includes at least one wash station, at least one electrically operated fixture associated with the wash station, a control system configured to control a flow of a fluid through the at least one electrically operated fixture, a power source selectively coupled to the control system, and a power management system coupled to the power source to control the power provided to the control system. The power management system includes a detector configured to monitor the output voltage of the power source, and a switch configured to electrically disconnect the power source from the control system when the output voltage of the power source drops below a predetermined level.
