Abstract:
1. A light positioning system for use in transferring a container to a buffer, the light positioning system comprising: a light signal disposed adjacent the buffer for guiding an operator to position a chassis into the buffer; a program logic controller associated with the light positioning system; a thru beam sensor, wherein the thru beam sensor senses movement of the container into the buffer and outputs data to the program logic controller; and a distance sensor, wherein the distance sensor determines a distance from the distance sensor to the container and outputs data to the program logic controller; wherein the program logic controller determines a length of the container based on the data received from the thru beam sensor and the distance sensor, and wherein the program logic controller provides an output signal to the light signal based on the length of the container and the data received from the distance sensor.
