Abstract
An architectural window covering having a programmable electric motor is disclosed. The architectural window covering includes a head rail comprising at least one cavity, a shade coupled to the head rail, a bottom rail coupled to the shade, and at least two tandem stacked motors coupled to the shade via a drive rail such that the at least two motors fit within the at least one cavity of the head rail.
Claims20
An architectural window covering, comprising:
- a head rail comprising at least one cavity;
- a shade coupled to the head rail;
- a bottom rail coupled to the shade;
- and
- at least two tandem stacked motors coupled to the shade, wherein:
- the at least two motors cooperate to rotate a single drive shaft and the at least two motors fit within the at least one cavity of the head rail.
3 more elements
A method of operating an architectural window covering, comprising the operations of:
- monitoring two or more motors that cooperate to rotate a drive shaft, whereby the motors are physically coupled together in tandem within a head rail of the architectural window covering and whereby the motors are electrically coupled together in a parallel fashion;
- measuring a movement characteristic associated with at least one of the two or more motors;
- and
- generating an error signal based on the movement characteristic associated with at least one of the two or more motors.
1 more element
An architectural window covering system, comprising:
- a plurality of architectural window coverings electrically coupled to each other, each architectural window covering comprising:
- a head rail comprising at least one cavity;
- a shade coupled to the head rail;
- a bottom rail coupled to the shade;
- and
- at least two tandem stacked motors coupled to the shade, wherein:
- the at least two motors are fully located within the at least one cavity of the head rail and the at least two motors cooperate to rotate a single drive shaft;
- and
- wherein a first architectural window covering within the plurality communicates at least one programming signal to a second architectural window covering within the plurality.
