  • Patent number: 7486146
    Abstract: A loop system capable of auto-calibrating an oscillating frequency range includes a frequency error detector, a voltage controlled oscillator (VCO), a voltage input unit, and a switch. The frequency error detector includes a rotational frequency detector, a state machine, and an up-down counter. The rotational frequency detector is used for comparing the reference frequency and the feedback frequency. The state machine is used for determining an auto-calibration state. The up-down counter is used for generating the second control signal or the coarse-lock-state signal. The VCO is used for selecting to operate at one of a plurality of frequency operating curves so as to generate an oscillating signal. The voltage input unit is used for providing a fixed voltage to the VCO. The switch is used for switching the VCO to couple to the voltage input unit or to couple to a fine frequency tuner.

  • Publication number: 20080011351
    Abstract: A dye-sensitized solar cell comprises a metal substrate, a photosensitive dye, a transparent substrate, an insulating unit and an electrolytic solution. The metal substrate is made of titanium or titanium alloy and is used as an anode. A titanium dioxide (TiO2) thin film is provided on the surface of the metal substrate, and consists of a plurality of arranged TiO2 nanotubes. The photosensitive dye is absorbed on the surface of the metal substrate. A cathode is provided on a surface of the transparent substrate whose transparent part is a euphotic zone through which light can be irradiated to the photosensitive dye. The insulating unit is located between the anode and the cathode. The electrolytic solution fills the space between the anode and the cathode and surrounded by the insulating unit. A method for manufacturing the same is also disclosed.
