Abstract
A motorized window covering includes a motor and a housing that holds the motor and a dc battery. Also, within the housing is a wake-up signal amplifier that is constantly energized and a data signal amplifier that is only energized when a wake-up signal is received. A remote control unit is used to generate and transmit the wake-up signal and a data signal that is use to control the operation of the window covering.
Claims20
A motorized window covering, comprising:
- a remote control unit;
- a transmitter within the remote control unit;
- an actuator coupled to the window covering;
- a receiver within the actuator, the receiver receiving at least one signal from the transmitter;
- a wake-up signal amplifier electrically connected to the receiver;
- and
- a data signal amplifier electrically connected to the receiver.
4 more elements
A method for controlling a motorized window covering, comprising the acts of:
- deactivating a data signal amplifier;
- activating a wake-up signal amplifier;
- and
- activating the data signal amplifier only in response to a wake-up signal being received by the wake-up signal amplifier.
1 more element
A system for controlling a motorized window covering, comprising:
- an actuator mechanically coupled to an operator of the window covering;
- a receiver within the actuator;
- a wake-up signal amplifier electrically connected to the receiver;
- a data signal amplifier electrically connected to the receiver;
- and
- a processor within the actuator, the processor including a program for controlling the actuator in response to at least one wake-up signal and at least one data signal being received by the receiver.
