A tray transfer arm which is widely used regardless of kinds of customer trays and capable of maintaining the stability of holding ICs to be tested. A power supply circuit controls power supply to an integrated circuit device having a built-in IC chip. In one embodiment, a geophysical location is stored in the memory of the device upon initial installation. This type of lightweight structure also permits scheduling activities to be performed in a disconnected mode, which can then be later synchronized with the server to confirm the booking. The illumination apparatus is explosion proof, and the illuminable plastic tank can be used to store, carry and dispense all commercial retail fuels. The system also includes an adapter disk containing electronics that process signals produced by each embedded sensor and that transmits sensor information to a data processing platform for further processing of the transmitted information.
