A package for containing sterile packed items is formed from the joining of a first sheet of material and a second sheet of material. A Bayesian network model is created based on information obtained from a Fault Isolation Manual, where the FIM provides tests to be performed in troubleshooting the fault to determine a root cause of the fault. With the use of a coaxial configuration, a windmill, a speed-increasing gearbox, the excitation synchronous generator, and a motor are integrated in the same shaft. The anterior support device also includes first and second movable rods secured to the first and second pivotable connectors. The racing horses to start a horse race are expressed by means of computer graphics, the existing past data associated with the racing horses is retrieved into the computer graphic horses, and a virtual horse race is started on a display screen, so that a finishing order of the horse race can be predicted according to an action and a result of the virtual horse race. The device is concealed by a cap that is designed to prevent ingress of ambient matter.
