An integrated process and apparatus for integrating an alkene derivative process, such as ethylene oxide process, with an ethylene process so that any ethylene entrapped in the purge stream of the alkene derivative process can be effectively recovered through the ethylene process portion of the integrated process. While subjected to rotational and translational forces, each draw unit disposed within the housing supplies electric current from a power source to a receiving system. A collecting device to catch any liquid dripping from the sample holder can be placed underneath the sample holder during transport. When the IC under test has a fault, the power source current flows with a period nT, where n is an integer different from n, or an abnormal power source current flows with the period nT, due to a change of the state shift of the IC under test. Selected surfaces of the protective enclosure can be coated with conductive materials.
