Abstract: An anti-overflow hammer and handle fixing structure includes a hammer body and a handle body. The hammer body has a flared slot, and the handle body has a fitting fixed head. After the flared slot of the hammer body is sheathed on the fitting fixed head of the handle body, an adhesive is filled up into the flared slot to improve the stability of combining the hammer body with the handle body and prevent any extra adhesive residue from overflowing to improve the assembly convenience and the structural assembly stability to achieve excellent structural stability and assembly convenience.

Abstract: A remote controller comprises a wireless communication interface and a processing unit. The wireless communication interface is communicatively connected with another remote controller. The processing unit is electrically connected with the wireless communication interface. The processing unit generates a first identification code and a second identification code and transmits the first identification code and the second identification code to the another remote controller through the wireless communication interface. The another remote controller transmits the first identification code and the second identification code to a controlled device to establish an indirect pairing relationship between the remote controller and the controlled device and a direct pairing relationship between the another remote controller and the controlled device. A pairing method of remote controllers is also disclosed.

Abstract: A lighting device driving apparatus, a lighting device driving system, and a driving method thereof are provided. The lighting device driving system includes a signal generation unit and N lighting device driving apparatuses. The signal generation unit generates a serial data flow, wherein the serial data flow includes at least N data frames. The 1st lighting device driving apparatus is coupled to the signal generation unit, and the ith lighting device driving apparatus is coupled to the (i+1)th lighting device driving apparatus. A signal processing unit of the lighting device driving apparatus detects identification codes of the data frames to receive control data of the ith data frame and adjusts the identification code of the ith data frame into a non-standard data format. Thereby, the lighting device driving system can receive the control data without any address and reduce interference to the serial data flow.

Abstract: A wireless network system for data transmitting securely is disclosed. The system comprises a central control end for generating a cipher password per predetermined time unit. The central control end has a first Zigbee chip, a computer terminal for a user to input parameters, and a cryptographic algorithm program provided wherein the cryptographic algorithm program and the parameters are provided for password encryption using the cryptographic algorithm program is run by a microprocessor of the first Zigbee chip. The system also comprises a data transmitting end and a several data receiving ends. The data transmitting end using the Zigbee decrypts the cipher password and encrypts the data file using the plain password and the Zigbee chip. The data receiving ends using the Zigbee decrypt the cipher password and decrypt the cipher data file into plain data file by the WiFi chips using plain password.
