Abstract
Window controllers and methods for controlling tinting and other functions of tinting zones of multi-zone tintable windows and multiple tinting zones of a group of tintable windows.
Claims21
A control system for controlling a plurality of tinting zones of a tintable window, the control system comprising:
- at least one window controller;
- and
- at least first and second voltage regulators connected in parallel to the at least one window controller,
- wherein,
- the first voltage regulator is connected to one or more first bus bars configured to apply voltage and/or current to a first side of a first tinting zone of the plurality of tinting zones, the second voltage regulator is connected to one or more second bus bars configured to apply voltage and/or current to a first side of a second tinting zone of the plurality of tinting zones, and
- the at least one window controller applies a same voltage to a plurality of third bus bars collectively disposed at second sides of the first and second tinting zones opposite the respective first sides.
3 more elements
A method of controlling tint of a plurality of tinting zones of a tintable window, the method comprising:
- (a) determining a voltage and/or a current to apply to each tinting zone of the plurality of tinting zones;
- and
- (b) using at least one window controller to:
- (i) apply the voltage and/or current for a first tinting zone of the plurality of tinting zones to a first voltage regulator connected to one or more first bus bars configured to apply respective voltage and/or current to a first side of the first tinting zone;
- (ii) apply the voltage and/or current for a second tinting zone of the plurality of tinting zones to a second voltage regulator connected to one or more second bus bars configured to apply respective voltage and/or current to a first side of the second tinting zone;
- and (iii) apply a same voltage to a plurality of third bus bars collectively disposed at second sides of the first and second tinting zones opposite the respective first sides.
