Abstract: A display device includes a RFID tag unit, a display unit, a processing unit and a power supply unit. The RFID tag unit follows a wireless communication standard of a RFID system to receive a wireless signal and outputs identification information. The processing unit electrically connected with the RFID tag unit and the display unit receives the identification information and outputs to the display unit for displaying. The power supply unit supplies operation power required to the processing unit and the display unit. The required power while the above-mentioned display device refreshes the information is supplied by the power supply unit, so that the information can be refreshed with longer communication distance and power saving is achieved. A display system including the above-mentioned display device and a reader/writer device is also disclosed.

Abstract: A mobile garbage incinerator having an incinerator body unit. The incinerator body unit includes a hanging drum for lifting and dumping garbage into a collecting tank. Garbage is then moved into a main incinerating room for a first stage incineration process. The resulting ashes are collected and compressed. The resulting waste gases are passed into a sphere-shaped secondary incinerating room. The resulting quasi-purified air is passed into an air-circulating tank for separating dust particles. The resulting further purified air is passed through a water curtain and then passed into the atmosphere.
