Abstract: The present approach relates to the design and use of a functionally closed bioreactor designed to immobilize, culture, and mature tissue on a loading platform. The bioreactor may be equipped with sensors for tissue monitoring which in conjunction with stiffness data can provide closed-loop control of tissue maturation. Based on a relationship between cartilage stiffness and tissue maturity, measurements of stiffness can be acquired and used as a surrogate for cartilage maturity without the need for destructive tests.

Abstract: Disclosed is an interconnected transportation network system, wherein same is related to the field of transportation facilities and control, and comprises a main transportation system, a transfer system and an entry/exit system. The main transportation system is formed of a closed annular rail vehicle, and the annular train moves continuously on a T-shaped track to fulfil a passenger transportation task by means of multi-point drive. The transfer system (intercommunication) is of the same structure as that of the main transportation system, and the passengers transfer between main transportation lines by means of the transfer system. The entry/exit system (terminal) is formed of an annular buffer vehicle system and a stepping speed control system, and the passengers enter or exit the main transportation lines in a self-service manner by means of the entry/exit system.
