Abstract
Provided herein are systems and methods for use in controlling a translocation process of a pneumatic tube system in order to reduce the amount of energy transferred from the tube system to a pneumatic carrier and, hence, its contents. Generally, these utilities entail identifying and/or reducing forces applied to a pneumatic carrier traveling through a travel path within a pneumatic tube system. The systems and method disposed herein allow for varying the velocity of a pneumatic carrier as it passes through a travel path of the pneumatic system. Such varying of the velocity allows for reducing the total forces applied to the pneumatic carrier during passage through the system. In one arrangement, the power output of a power source connected to a compressor device is altered to vary the velocity of pneumatic carries in the system.
