摘要： The present invention discloses a dual-band RF transceiver. The transceiver comprises a first module, used as the RF front-end of the dual-band transceiver and used for receiving and transmitting a first RF signal and a second RF signal; a second module, electrically connected to the first module, used as the IF IQ modulator/demodulator of the dual-band RF transceiver; a third module, electrically connected to the first and the second modules, used as the tripe-band phase-locked frequency synthesizer of the dual-band RF transceiver and used for providing a first local oscillating signal and a second local oscillating signal to the first module, and a third local oscillating signal to the second module. The dual-band RF transceiver according to the present invention realizes the dual-band triple-mode operation of IEEE802.11 a/b/g by a single dual-band RF module, and therefore the circuit size, power dissipation, component count, and cost can be dramatically reduced.

摘要： A printer is communicatively connected to a terminal and a slave. The printer creates a secure printing group, and allows the terminal and slave to join the secure printing group. The terminal generates a print job, and sends the print job to the printer. The printer generates a first inspection message according to the print job, and sends the first inspection message to the terminal. The terminal selects the slave as a printing delegate, and sends a message that is derived at least in part from the first inspection message to the slave. The slave sends a second inspection message to the printer, wherein the second inspection message is derived at least in part from the message sent from to the terminal to the slave, and requests the printer to execute the print job. The printer executes the print job when the second inspection message matches the first inspection message.

摘要： A method for safely downloading setting data in a Voice over Internet protocol (VoIP) system including a server, a VoIP device, and a console, includes steps of: establishing communication between the console and the VoIP device; determining whether a certificate authority of the VoIP device is valid; generating a session key randomly if the certificate authority of the VoIP device is valid; encrypting the setting data of the VoIP system employing the session key; encrypting the session key employing a public key; transmitting the encrypted data and the encrypted session key to the VoIP device; decrypting the encrypted session key employing a private key after the VoIP device received the encrypted data and the encrypted session key; decrypting the encrypted data to restore the setting data employing the session key; and checking whether the setting data are correct data.
