SYSTEMS AND METHODS FOR CONTROLLING WINDOWS WITH VARIABLE LIGHT TRANSMISSION
First Claim
1. A method of controlling a transmissivity of a window portion of a variable transmissivity window system, the method comprising:
- measuring an actual humidity level at a location;
setting a desired humidity level for the location via a user input, incrementally adjusting a transmissivity of the window portion to maintain the desired humidity level, wherein the transmissivity is configured to be reduced using a first electrical input; and
setting a minimum transmissivity limit for the window portion, wherein the minimum transmissivity limit is configured to provide visibility through the window portion;
wherein incrementally adjusting the transmissivity comprises decreasing the transmissivity of the window portion to maintain the desired humidity level.

Abstract
Systems and methods for controlling windows with variable light transmission are disclosed. In one embodiment, a system includes a sensor adapted to receive a light intensity, a user input device adapted to receive a user input value, a window having a variable transmissivity portion, and a control system. The control system is operatively coupled to the sensor, the user input device, and the window, and is adapted to receive the light intensity and user input value and to adjust a transmission level of the variable transmissivity portion of the window based on at least one of the light intensity and the user input value. The sensor includes a sensor adapted to receive a light intensity, a temperature, a humidity, or other environmental variables. In other embodiments, the system also includes a ventilation system, an air conditioning system, or a humidity control system.

11. A computer-readable medium having computer-executable instructions that, when executed, perform a method comprising:
-
measuring an actual humidity level at a location;
setting a desired humidity level for the location via a user input;
incrementally adjusting a transmissivity of a window portion to maintain the desired humidity level, wherein the transmissivity is configured to be reduced using a first electrical input; and
setting a maximum light level for the window portions;
wherein incrementally adjusting the transmissivity comprises increasing the transmissivity of tie window portion to maintain the desired humidity level provided that a light level provided by the adjusted transmissivity does not exceed the maximum light level. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
