Abstract: A system uses multiple tilt sensors mounted to the vehicle frame and the vehicle suspension system to detect lateral acceleration and lateral load transfer. The system uses these measurements to determine a lateral load transfer ratio indicative of an actual roll moment compared to a maximum roll moment. The measurements from the tilt sensors are also used to calculate an effective center of gravity height. A display coupled to the system provides the vehicle operator with a read out of the load transfer ratio and effective center of gravity height. The display enables the vehicle operator to more completely understand the nature of the vehicle load and thereby allow the vehicle operator to avoid conditions likely to lead to a vehicle rollover accident.

Abstract: A brake condition monitoring system includes a central control receiving signals from each of the several brake actuators mounted on a vehicle.

The signals from each brake actuators are unique such that the control can determine which brake actuator each signal is from. The control is also capable of monitoring conditions other than movement of a push rod.

Abstract: Apparatus and methods for monitoring a characteristic of fluid flow through a fluid dispenser that permit adverse flow conditions to be monitored, analyzed and displayed to an operator. The monitor samples either the static or firing pressure a predetermined number of times and calculates an average static and firing pressure over the sampling period. The average pressure values are compared to high and low warning and alarm limits and warning and alarm error codes are produced as a function thereof. In addition, individual sampled values are compared to the high and low warning and alarm limits and pressure values exceeding the limits during a sampling period are counted. Warning and alarm error codes are produced as a function of the counted values exceeding predetermined count values.
