Automatic retention apparatus
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.

8. The automatic retention apparatus of claim 1 , comprising:
a memory storing configuration data of the actuator and historical data of past sensor output and changes to the tension on the retention member, wherein the processor is configured to determine a tension to apply to the retention member based on input from the sensor and the configuration data in the memory; and
a wireless communication module controlled by the processor and configured to wirelessly communicate with a remote computer to receive configuration data and send the historical data.
9. The automatic retention apparatus of claim 7 , comprising:
a second retention member surrounding at least a portion of an ankle region of an article of footwear, wherein the second retention member is positioned adjacent to the outside surface of the article of footwear, wherein the second retention member defines one or more holes passing through at least a portion of the second retention member; and
a second actuator that includes a second gear with multiple teeth, the second gear rotatable about a second axis of rotation and positioned in the actuator so that at least one of the multiple teeth of the second gear extend into the one or more holes of the second retention member, wherein the second actuator is coupled to the second retention member adjacent an outside surface of the ankle region of the article of footwear, and wherein the second gear is configured to adjust tension on the second retention member as it rotates;
wherein the processor is configured to control the second actuator to rotate the second gear about the second axis of rotation to adjust tension on the ankle region of the article of footwear according to input from the sensor.
10. An automatic retention apparatus for automatically retaining a first object adjacent to a second object, comprising:
a retention member coupled to the first object and surrounding at least a portion of the second object, wherein the retention member is mounted outside of the first object;
an actuator that includes a rotating member rotatable about an axis of rotation, wherein the rotating member is outside the first object and coupled to the retention member, wherein the actuator rotates the rotating member in a first direction to increase a length of the retention member reducing tension on the retention member, and wherein the actuator rotates the rotating member in a second direction opposite the first direction to decrease the length of the retention member increasing tension on the retention member; and
a processor responsive to input from at least one sensor and configured to control the actuator according to the input from the sensor, wherein the processor is configured to control the actuator to rotate the rotating member in the first or second direction to adjust tension on the retention member to automatically retain the first object adjacent to the second object based on input from the sensor;
wherein the retention member is arranged along a long axis that is substantially parallel to the axis of rotation of the rotating member.
