SPRING CYCLE COUNTER
First Claim
1. A spring cycle tracker system for a track-mounted door having at least one spring, the door having an open position and a closed position, and a direction of travel between the open position and the closed position, the system comprising:
- a spring cycle tracker mounted to the door at a height greater than 50% of the total height of the door when the door is in the closed position, comprising;
a sensor having at least one sensing element and an output; and
a controller having a counter display and an input coupled to the output of the sensing element;
such that when the door is moved, the sensor and the controller move with the door, the sensor generates a signal on the output of the sensor correlated to the door motion, and the controller senses the signal from the sensor on the input and increments the counter display, such that the counter display tracks a number of times the spring is used.

Abstract
A spring cycle tracker system for a door mounted on a track having at least one spring, with the door having an open and closed position. The system has at least one sensed element and a tracker. The tracker has a sensor having at least one sensing element; and a controller having a counter display, at least one input signal from the at least one sensing element and at least one output signal. The sensed element and the tracker are mounted such that when the door is moved towards the open position and/or the closed position, the sensed element and the controller are moved relative to each other so that the sensing element senses the sensed element, sending an input signal to the controller, incrementing the counter display, tracking a number of times the spring is used.
