What is claimed is: 1. An ambulance cot comprising:a) a base frame;b) a litter frame;c) an elevating mechanism interconnecting said base frame and said litter frame and being configured to facilitate movement of said base frame and said litter frame toward and away from each other;d) an ultrasonic sensor, wherein said ultrasonic sensor is configured to provide voltage information that indicates, throughout the entire range of said cot from fully raised to fully collapsed, the distance between said ultrasonic sensor and a slider block attached to a cross tube attached to main rails of telescoping legs of said cot;e) a data storage device, wherein said data storage device stores programmable distances between said ultrasonic sensor and said slider block, wherein said programmable distances correspond to at least a maximum desired cot height and a minimum desired cot height; andf) a controller, wherein said controller is wired to said ultrasonic sensor and facilitates said movement of said base frame and said litter frame toward and away from each other via comparing actual distance between said ultrasonic sensor and said slider block to said programmable distances stored in said data storage device, wherein said controller stops movement of said elevating mechanism when said actual distance between said ultrasonic sensor and said slider block reaches one of said programmable distances stored in said data storage device.
