Abstract

The inventive subject matter provides a system and a method for automatically controlling appliances via a mechanical controller. In one aspect of the invention, the system includes a first circuitry communicatively coupled with one or more sensors and configured to generate a motor controlling signal based in part on a reading from the sensor. The system also includes a mechanical device in contact with a lever of the mechanical controller. The system also includes a second circuitry configured to cause the mechanical device to move the lever as a function of the signal received from the first circuitry to control the appliance.

Claims

1. A system for automatically controlling an external device using a mechanical controller based on readings from a sensor, wherein the mechanical controller comprises a lever, the system comprising:

a first circuitry communicatively coupled with the sensor, and configured to generate a motor controlling signal based in part on a reading from the sensor;

a mechanical device in physical contact with at least a portion of the lever of the mechanical controller, and configured to physically move the portion of the lever from a first position to a second position, and from the second position to a third position, wherein the first, second, and third positions are different; and

a second circuitry communicatively coupled with the first circuitry and the mechanical device, and configured to cause the mechanical device to physically move the portion of the lever from the first position to the second position, as a function of the motor controlling signal received from the first circuitry, to thereby control the external device, wherein the external device has first, second and third operating states that are controlled by movement of the portion of the lever to the first, second, or third positions, respectively.

2. The system of claim 1, wherein the first circuitry comprises:

a processing unit; and

an analog-to-digital converter configured to convert an analog signal received from the sensor to a digital signal and pass the digital signal to the processing unit.

3. The system of claim 1, wherein the second circuitry comprises:

a motor controller circuitry; and

a motor driver.

4. The system of claim 3, wherein the motor driver comprises a power amplifier.

5. The system of claim 1, wherein the second circuitry is communicatively coupled with the mechanical device via an RJ45 cable.

6. The system of claim 1, wherein the mechanical controller comprises a mechanically controllable dimmer having at least one of a linear motor and a potentiometer.

7. The system of claim 1, wherein the mechanical device comprises a track and a robotic fork movable along the track.

8. The system of claim 7, wherein the robotic fork comprises a concavity for partially enclosing the lever of the mechanical controller.

9. The system of claim 7, wherein the mechanical device is configured to move the robotic fork to at least three positions along the track to move a slider to one of at least three operating states.

10. The system of claim 9, wherein the first circuitry is further configured to:

select a power level from at least three power levels based in part on the reading from the sensor;

embed information related to the selected power level in the motor controlling signal; and

transmit the motor controlling signal to the second circuitry.

11. The system of claim 10, wherein the second circuitry is further configured to cause the mechanical device to move the robotic fork to one of the at least three positions based on the motor controlling signal.

12. The system of claim 1, wherein the external device comprises one of a lighting device and a fan.

13. The system of claim 1, wherein the sensor comprises at least one of a luminance sensor, an occupancy sensor, a temperature sensor, and a humidity sensor.

14. The system of claim 1, further comprising a user interface that enables a user to configure how the second circuitry causes the mechanical device to move the lever as a function of the signal.

15. The system of claim 14, wherein the user interface enables the user to configure how rapidly the light dims.

16. The system of claim 14, wherein the user interface enables the user to configure a minimum and maximum luminosity of the external device.

17. The system of claim 9, wherein the slider comprises a dimming slider that adjusts a luminance level of a lighting fixture.

18. The system of claim 17, wherein the mechanical device is configured to move the lever to any position along a continuous, non-discrete path of the track to adjust a power setting of an appliance.

19. The system of claim 1, wherein the mechanical device comprises a power amplifier that amplifies the motor controlling signal to physically move the portion of the lever.
