SYSTEMS AND METHODS FOR CONTROLLING SPOOLING OF LINEAR MATERIAL
First Claim
1. An automatic reel for facilitating the spooling of linear material, the automatic reel comprising:
- a rotatable member configured to wind a linear material as the rotatable member rotates in a first direction, the rotatable member being further configured to deploy the linear material as the rotatable member rotates in a second direction;
a motor configured to interact with the rotatable member to selectively control a rotational velocity of the rotatable member in the first direction or in the second direction;
a sensor configured to monitor a motor signal indicative of a tension of the linear material; and
control circuitry in communication with the sensor, the control circuitry configured to cease rotation of the rotatable member in the first direction when the motor signal monitored by the sensor indicates that the tension of the linear material exceeds a predetermined threshold.

Abstract
Preferred embodiments of the invention comprise an automatic reel capable assisting a user when attempting to unspool a linear material, such as a water hose. The automatic reel includes a control system having a motor controller capable of sensing a pulling of, or increased tension of, the linear material and capable of causing a motor to rotate to unspool the linear material. In certain embodiments, the motor controller tracks the length of the unspooled portion of the linear material and/or reduces the spooling speed of the motor when retracting a terminal portion of the linear material.
