  • Patent number: 8761403
    Abstract: A method and a system of secured data storage and recovery are provided. First, a secured key and an encrypted user password of a storage device are obtained by using a controller of a storage device. Then, the secured key is encrypted by using the encrypted user password to generate a first private key, the encrypted user password is encrypted by using the secured key to generate a second private key, and data to be stored is encrypted by using the secured key. Finally, the encrypted data, the first private key, and the second private key are transmitted to a remote device for storage through a host. Thereby, the security of data storage is enhanced and data recovery mechanism is provided when the storage device is damaged or lost.

  • Publication number: 20080068052
    Abstract: The present invention relates to a circuit providing frequency-doubling function. More particularly, the present invention relates to a frequency doubler circuit comprising dual Gilbert mixers in replace with the single mixer scheme in the conventional direct conversion transceiver circuit. CMOS technology is preferred in order to lower size and power consumption of the specific IC. With a balanced output load, either is resistor-capacitor (RC) load, resistor-inductor (RL) load, or a combination of the three (RLC), symmetrical output waveforms are obtained thereby. Notice that two quadrature inputs and their inverse-phase signals are provided to the purposed dual Gilbert mixer circuit, and two outputs in inverse-phase are obtained accordingly as meditated in this invention.
