Claims20
A window shade system for a window of an enclosed space, the system comprising:
- a window shade configured to cover at least a portion of the window;
- a radiant heating fabric extending over at least a portion of the window shade;
- a power supply configured to supply electric current to the radiant heating fabric;
- and
- a controller configured to control the supply of electric current to the radiant heating fabric based on an occupant comfort level.
A window shade system for a vehicle with a cabin and a window enclosing a portion of the cabin, the system comprising:
- a window shade configured to cover at least a portion of the window;
- a radiant heating material incorporated into the window shade;
- a power supply connected with the radiant heating material;
- a heating, ventilation and air conditioning (HVAC) system configured to condition the cabin to a set temperature;
- and
- a controller configured to:
- control the power supply to supply electric current to the radiant heating material;
- and
- control the HVAC system;
- wherein the power supply and the HVAC system are controlled in coordination through a control module that operates to bring a cabin temperature in the cabin to a set point temperature.
A window shade system for a vehicle with a cabin and a window enclosing a portion of the cabin, the system comprising:

- a power supply connected with the radiant heating material
- a heating, ventilation and air conditioning (HVAC) system configured to condition the cabin to a set temperature;
- a first sensor configured to determine an ambient temperature outside the cabin;
- a second sensor configured to determine a cabin temperature inside the cabin;
- and
- a controller configured to:
- calculate an equivalent homogeneous temperature (EHT) based on the ambient temperature and the cabin temperature;
- control the power supply to supply electric current to the radiant heating fabric;
- and
- control the HVAC system;
- wherein the power supply and the HVAC system are controlled in coordination based on the EHT.
