Claim of US Patent No. 10,342,099

1. A load regulation device for controlling an electrical load, the load regulation device comprising:a load regulation circuit configured to control the electrical load; and
a control circuit configured to control the load regulation circuit to control an amount of power delivered to the electrical load, the control circuit configured to operate in an on state during which the control circuit controls the load regulation circuit to energize the electrical load, and in a low power state during which the electrical load is unenergized;
wherein the control circuit is configured to:
receive an indication of a user's presence;
transition from a low power state to a ready state in response to receiving the indication, wherein the ready state is characterized by the load regulation device using more power than the low power state and the electrical load being unenergized;
wait in the ready state for a change state instruction;
transition from the ready state to the low power state if the change state instruction is not received within a first predetermined period of time;
transition from the ready state to the on state in response to receiving the change state instruction within the first predetermined period of time; and
transition from the on state to one of the ready state or the low power state in response to receiving an actuation of an actuator or in response to determining a lack of the user's presence in a vicinity of the electrical load for a second predetermined period of time.
