Abstract: A temperature recorder mainly includes a micro control unit (MCU), a temperature sensing circuit, a memory with RF transmission function, and at least one antenna unit. The MCU electrically connects to the temperature sensing circuit and the memory, and the antenna unit electrically connects to the memory. The temperature sensing circuit senses external temperature variations surrounding the temperature recorder, and the sensed temperature variations are progressed by the MCU and then stored into the memory in accordance with scheduled parameters. The temperature recorder can be connected externally through wired serial transmitting interface or wireless radio frequency (RF) transmitting interface when internal temperature data needs to be retrieved, or a new parameter needs to be written into the memory. Thus, the memory in the temperature recorder can be retrieved and written via both wired connection and wireless connection, the usage of the temperature recorder is more flexible.

Abstract: A display method for electronic paper label apparatus first detects a serial number of an electronic paper label by a handheld device. Then a wireless display signal corresponding to the serial number is sent from the handheld device to the electronic paper label. Finally, the display content of an electronic paper of the electronic paper label is changed by the wireless display signal.

Abstract: A system for real-time photograph printing service includes a personal terminal, a telecom terminal, and a printing service terminal. The personal terminal is triggered to transmit a digital photograph file and a phone number according to the personal terminal. The telecom terminal fetches a communication address of a user of the personal terminal according to the received telephone number, and the printing service terminal receives the digital photograph file to print out a physical photograph. Finally, the printed photograph is send to the communication address for user by post.
