Abstract: A wireless communication circuit and a transport device for sending rescue message are provided. The wireless communication circuit is arranged in a transport device for sending a rescue message to a cellular network and includes a radio transceiver, a signal amplifier circuit, a plurality of filters, and a first switch. The radio transceiver converts a baseband signal to a radio frequency signal and determines whether the cellular network has been connected. The first switch includes an input end and a plurality of output ends, and is electrically connected between the signal amplifier circuit and the plurality of filters. The first switch connects the input end and one of the plurality of output ends in sequence until the radio transceiver determines the cellular network has been connected. The wireless radio transceiver sends the rescue message through the first switch.

Abstract: Disclosed are an LED floor lamp and its circuit. The LED floor lamp includes a power module and a light emitting module, and the power module includes a power circuit board and a first coil, and the light emitting module includes a light emitting circuit board, a second coil and an LED light source. The power circuit board and the light emitting circuit board are parallel to each other, and the first coil is fixed on the power circuit board and proximate to the second coil of the light emitting module, and the second coil is fixed on the light emitting circuit and proximate to the first coil of the power module. The LED light source is installed on the light emitting circuit. Therefore, the floor lamp and its circuit can be installed, adjusted, and maintained easily, and the LED light source can be changed conveniently.

Abstract: Disclosed is an outdoor device management system, and a recognition device having a blank record is installed in the outdoor device and includes a first transmission module for electrically connecting a second transmission module of an electronic device such as a mobile phone or a tablet PC. When the outdoor device is installed, an identification code of the electronic device is set and provided to the outdoor device, while coordinates of the outdoor device are captured to form installation data containing the identification code, and the installation data are transmitted to the terminal device, so that the terminal device labels the outdoor device at a corresponding location of a map to complete the installation operation, and the electronic device transmits the identification code or installation data to the recognition device through the second transmission module and the first transmission module for storage and record.
