Objective To design a virtual console for the movable high frequency X-ray machine system type MME2002. Methods An experimental circuit was designed to simulate the real circuit and realized the serial communication between microcomputer and MCU (micro control unit). The simulating software was designed in Visual Basic 6.0, using MSComm to control serial communication. It simulated the functions of the initial console, including setting parameters, sending commands to the machine and storing and transferring the best data of a special condition by file operation in VB. Results The console was designed based on PC. Conclusion This console can replace the console using circuit boards and keys. It can be combined with the X-ray machine systems' image collection software, making the machine's operation more easy and convenient.

Cardiopulmonary resuscitation (CPR) is vital for cardio arrest victims; in this field, researches have been aiming at its mechanism, operation guidelines, new CPR machines and so on. This paper summarized the studies on the mechanical characteristics of the thorax under CPR, and on the simulation work of sternal-displacement relationship in CPR manikins. The data from modeling work showed that the thorax's sternal-displacement relationship could be graphically represented by a hysteresis curve. As the actual CPR manikins' mechanical structures of the thorax are too simplified, it is necessary to do the work of improvement.
