Abstract: A safety curtain and system includes multiple light emitters and multiple light receivers to detect traffic approaching a doorway. The safety curtain my include pairs of multiple light emitters and receivers positioned on both sides of a passageway (doorway) so as to detect approaching traffic. The multiple light emitters and light receivers may detect a height of an approaching traffic (e.g., person or vehicle) and initiate warning lights of a possible door closing. The detected approach of traffic may cause the door to be stopped, reversed or slow down. The system may include a computer to monitor the signals from the receivers and may control the motion of the door.

Abstract: An air suspension system which includes the ability to adjust the working air volume, pressure, and spring rate of one or more air springs to reduce or eliminate various types of vehicle oscillations. Switchable or variable volume air spring assemblies have the ability to change air spring volumes, which results in changes in air spring rates, and therefore changes in normal loads applied to each wheel. Changes in wheel normal loads change wheel traction (slip) and vehicle dynamics (pitch, roll, yaw displacement, rate and acceleration). The spring rate of one or more of the air spring assemblies is adjusted automatically when a vehicle oscillation is detected. This vehicle oscillation is calculated from the raw vehicle signals, or another vehicle module may detect the oscillation and send a command to the air suspension module to change the spring rates. This changes the natural frequency of the vehicle, dampening the oscillation.

Abstract: An air suspension system which includes a Dynamic Load Transfer (DLT) function. DLT is a process of transferring vehicle load, or varying normal loads applied to each wheel of the vehicle, using switchable volume or variable volume air spring assemblies. Switchable or variable volume air spring assemblies have the ability to change air spring volumes, which results in changes in air spring rates, which result in changes in normal loads applied to each wheel. Changes in wheel normal loads change wheel traction (slip) and vehicle dynamics (pitch, roll, yaw displacement, rate and acceleration). Each air spring assembly may have multiple volume air chambers that are switched “on” and “off,” a variable volume air chamber, or the air spring assembly may be coupled with other air springs, or air chambers, that are switched or varied.
