Return-to-zero formatted data is recovered and transmitted using non-return-to-zero devices. A tag ID code of the RFID tag is received by a reader and then is transmitted to the server. For converting the input voltage into an impressed output voltage, the negative feedback voltage is a voltage proportional to the output voltage. The mouse may further include at least two electrodes. The plant is highly tolerant to cold, drought, rain and heat, and exhibits high resistance to pests and diseases, particularly to powdery mildew.
