Automatic air duct register

Abstract

An automatic air duct register system operating within an HVAC system comprises an automatically controlled register. The register includes louvers which are electromechanically adjusted in order to control the airflow through the register. The register may be opened or closed, responsive to a programmable electronic timer or clock, an occupancy sensor, or in response to a measured temperature. The register system may be part of a control network, wherein the network communicates programming information to the register system, and wherein the network reads information from the register system. The register system may be self-powered, utilizing an electrical generator powered from airflow from the duct attached to the register system.

         9 . The system of  claim 5 , wherein the temperature sensor utilizes a wireless temperature sensor. 
     
     
         10 . The system of  claim 3 , wherein the temperature sensor utilizes an infrared sensor. 
     
     
         11 . The system of  claim 10 , where the temperature sensor measures a temperature at least ten centimeters away from the duct. 
     
     
         12 . The system of  claim 5 , wherein the temperature sensor utilizes an infrared sensor. 
     
     
         13 . The system of  claim 12 , where the temperature sensor measures a temperature at least ten centimeters away from the duct. 
     
     
         14 . An automatically adjusted air duct register system, capable of adjusting the airflow through a register in an HVAC system, where the power to adjust the register is derived from the flow of air through the register. 
     
     
         15 . The system of  claim 14 , wherein power to adjust register is specifically derived from electric generator placed in the path of the register airflow. 
     
     
         16 . The system of  claim 14 , the register opened and closed responsive to an electronic timer or clock. 
     
     
         17 . The system of  claim 14 , the register opened and closed responsive to an electronic signal indicative of room temperature. 
     
     
         18 . The system of  claim 16 , wherein the register is additionally opened and closed responsive to an electronic signal indicative of room temperature. 
     
     
         19 . An automatically adjusted air duct register system, capable of adjusting the airflow through a register in an HVAC system, the register opened and closed responsive to the room temperature, the room temperature indicated by infrared sensor. 
     
     
         20 . The system of  claim 19 , where the infrared sensor measures temperature at least 10 centimeters away from the duct's air flow. 
     
     
         21 . The system of  claim 19 , wherein the register is inhibited from being opened or closed, unless an indicator indicates that the air duct connected to the register has airflow. 
     
     
         22 . The system of  claim 1 , where a wireless network system includes a node which permits a remote adjustment of the timer or clock. 
     
     
         23 . The system of  claim 3 , where a wireless network system includes a node which permits a remote adjustment of at least one of the timer or clock, or the temperature setting. 
     
     
         24 . The system of  claim 19 , where a wireless network system includes a node which permits a remote adjustment of the temperature setting.
