Abstract:
1. A louver system ( 100 ) for controlling airflow in a duct ( 110 ) from a forced air heating, ventilation, and air conditioning (HVAC) system comprising: (a) a housing ( (b) a positionable louver ( (c) a longitudinal slat ( (d) a slat positioning assembly ( (e) a mainspring assembly ( (f) a winding assembly ( (g) a motor ( (h) a local control system ( (i) a power supply ( (j) an electricity generator ( wherein upon receiving an activation signal, the local control system ( 750 ) sends a positioning signal via the microprocessor ( 760 ) to the solenoid actuator ( 570 ), wherein the solenoid actuator ( 570 ) releases the stored energy from the mainspring assembly ( 600 ) to actuate the slot positioning assembly ( 500 ) via the positioning gear ( 560 ) and the engagement tip ( 580 ), wherein the slat positioning assembly ( 500 ) rotates the slat ( 400 ) to a specified position, wherein in the fully open position, the slat ( 400 ) allows airflow, wherein the fully closed position, the slat ( 400 ) inhibits airflow, wherein in a position between the fully open position and the fully closed position (partially open), the slat ( 400 ) allows an inhibited rate of airflow, wherein the mainspring assembly ( 600 ) is wound via the winding assembly ( 650 ), wherein the winding assembly ( 650 ) is actuated via the hand crank ( 660 ) or the motor ( 700 ).
