Patent ID: 7950879

Claim:
A method for use in a computerized controller for operating a pneumatic carrier system where the pneumatic carrier system includes a plurality of user stations, pneumatic tubes and transfer devices, comprising the steps of: receiving, at said controller, an input requesting special handling for a pneumatic carrier; identifying a travel path for the pneumatic carrier through a pneumatic carrier system between an origination location and a destination location; accessing electronically stored path characteristic information for said travel path, said path characteristic information including at least smoothness information corresponding to at least one of expected carrier vibration over said travel path and expected carrier centripetal acceleration over said travel path; and based on said path characteristic information and said smoothness information for said travel path, generating an output control signal for variably controlling a power output of a power source connected to a pneumatic device that provides airflow to said pneumatic carrier system, wherein variably controlling the power output variably controls the velocity of said pneumatic carrier as it moves through said travel path between said origination location and said destination location.
