Patent attributes
An apparatus for automatically adjusting tension on retention member to hold multiple objects together. Examples include using retention apparatus to obtain optimal fit and use of a human wearable item such as article of footwear. Sensors may be used to sense changes in movement of the article of footwear, of the person wearing it, or of a third object such as a vehicle carrying the person. A retention member may surround at least a portion of the objects, and an actuator may be included that automatically rotates a rotating member such as a gear or pulley that may be coupled to the retention member. The rotating member may be configured to automatically adjust tension on the retention member many times per second based on control signals from control logic responsive to the sensors.
