Automatic faucets
First Claim
1. An automatic faucet, comprising:
- a housing forming partially an internal barrel and a faucet head and being constructed to include at least one water inlet conduit extending into said barrel and a water outlet for delivering water from a spout;
a faucet crown removably mounted on said faucet head;
a valve module including an electromagnetic actuator for controlling the water flow from the water outlet;
a sensor module constructed to provide sensor data influenced by a user; and
a control module located on a circuit board inside the housing of the faucet and constructed to receive said sensor data from said sensor module;
said circuit board being mounted inside said faucet head and extending below said faucet crown and being removable after removing said faucet crown from said faucet head;
wherein said internal barrel and said faucet head are constructed and arranged to releasably enclose and retain said valve module, said sensor module and said control module;
wherein said control module includes a controller constructed to receive said sensor data from said sensor module and execute a self-calibration and initialization algorithm and execute a sensing algorithm, wherein said self-calibration and initialization algorithm determines a noise signal level and a signal threshold for different power supply sources.

Abstract
An automatic faucet includes a housing forming partially an internal barrel and a faucet head and being constructed to include at least one water inlet conduit extending into said barrel and a water outlet for delivering water from a spout. The automatic faucet also includes a faucet head having a removable faucet crown and the spout, wherein the faucet crown is removably mounted to the faucet head. The automatic faucet also includes a valve module, a sensor module, a battery module, a turbine module, and a control module. The valve module includes a valve controlled by an electromagnetic actuator for controlling the water flow from the spout. The sensor module is constructed to provide sensor data influenced by a user. The control module is constructed to control opening and closing of the valve by providing signals to the electromagnetic actuator. The control module is also constructed to receive sensor data from the sensor module and execute a sensing algorithm. The control module is also constructed to execute a power management algorithm for managing electrical power generated by the water turbine and provided to and from the battery.
