Automatic lacing system
An article of footwear with an automatic lacing system is disclosed. The automatic lacing system provides a set of straps that can be automatically opened and closed to switch between a loosened and tightened position of the upper. The article further includes an automatic ankle cinching system that is configured to automatically adjust an ankle portion of the upper.
1. A method for automatically adjusting an active article of footwear when the article is in-use by a wearer, the method comprising:
sensing, using a weight sensor in the article of footwear, a change in a foot position of the wearer; and
in response to the change in the foot position as sensed by the weight sensor, and after a time delay that allows for insertion of the foot in the article of footwear, controlling an automatic lacing system to adjust a fit of the article of footwear relative to the foot of the wearer.
2. The method of claim 1 , further comprising generating, using a processor circuit, a control signal for the automatic lacing system, wherein the control signal indicates whether the change in the foot position as sensed by the weight sensor meets a response criteria, and wherein controlling the automatic lacing system includes in response to the control signal.
3. The method of claim 2 , wherein generating the control signal includes using the processor circuit to characterize a location of the foot of the wearer relative to the weight sensor.
4. The method of claim 1 , wherein controlling the automatic lacing system includes suppressing actuation of the automatic lacing system to maintain a tension characteristic of the article of footwear about the foot of the wearer.
5. The method of claim 1 , wherein controlling the automatic lacing system includes actuating the automatic lacing system to decrease a tension characteristic of the article of footwear about the foot of the wearer.
6. The method of claim 1 , further comprising detecting a gesture signal from the wearer and wherein controlling the automatic lacing system includes in response to the gesture signal.
7. The method of claim 1 , comprising sensing a tightness of the article of footwear about the foot and, based on the sensed tightness, further controlling the automatic lacing system to adjust the fit of the article of footwear.
8. The method of claim 1 , comprising sensing a torque or force applied by the automatic lacing system and, based on the sensed torque or force applied, further controlling the automatic lacing system to adjust the fit of the article of footwear.
