  • Publication number: 20210079814
    Abstract: A fluid storage tank can be configured to store a cooling fluid in a liquid state and a gas state. A first heat exchanger can be configured to release heat into the fluid storage tank. A second heat exchanger can be disposed fluidly downstream of the fluid storage tank and configured to exchange heat between the cooling fluid and a heat load. A pressure control device can be disposed fluidly downstream of the second heat exchanger. The first heat exchanger can be fluidly downstream of the second heat exchanger such that cooling fluid, after being heated in the second heat exchanger, passes through the first heat exchanger and thereby heats upstream cooling fluid resident in the fluid storage tank.

  • Patent number: 9678009
    Abstract: A method for a localized surface plasmon resonance (LSPR) sensing system is disclosed. The LSPR sensing system has an optical detection system and a test specimen with metal nanoparticles arranged in an anisotropic periodic manner that generates a phase signal of the LSPR sensing system. The method includes: emitting an incident light toward the test specimen to excite the metal nanoparticles, thereby generating an emergent light; using the optical detection system to detect phases of a first polarization state and a second polarization state of the emergent light, where the first polarization state is perpendicular to the second polarization state; and obtaining a phase difference spectrum between the phases of the first and second polarization states, thereby determining a half maximum (FWHM) of the phase difference spectrum.

  • Publication number: 20140354993
    Abstract: A localized surface plasmon resonance (LSPR) sensing system with anisotropic particles is revealed. The anisotropy of nanoparticles spectrally splits the phase spectra of two perpendicular polarizations thus inducing a phase difference between the two polarizations. An apparatus of ellipsometry is used to measure the phase difference. The simulated results demonstrate that the full width at the half maximum of the spectrum of phase difference is much narrower than the spectrum of transmittance. Therefore the figure of merit is dramatically increased and the performance of the refractive index sensor is improved.

  • Patent number: 8212422
    Abstract: The hand-held electronic device includes a central processing unit, a memory unit, a state-detecting unit, a state-determining unit, a main power supply unit, a standby power supply unit, and a power supply switching unit. After determining the presence of a fall state, the state-determining unit will output a fall instruction and which causes the central processing unit to enter a low current mode; meanwhile, the power supply switching unit monitors power output and continues to supply low-potential power. In case of a fall of the hand-held electronic device, the device and method protect operation data and reduce the otherwise power-consuming current. The less power-consuming current is conducive to the reduction of capacitance required for a backup battery. The low current mode is effective in reducing the time taken to recover the operation mode of the electronic device.

  • Patent number: 5425108
    Abstract: An automatic identification system for a car-plate which comprises a photographing apparatus and an image-processing CPU. The system disclosed in the present invention can be mounted in a car for automatically identifying a car-plate that is under a still or moving condition. The photographing apparatus is used for taking the image of a car-plate, and the image is then transmitted into the image-processing CPU, which accurately extracts the characters of a car-plate using a "Fuzzy inference" technique, and identifies the characters through a character structure analysis neural network. With the automatic identification system of the present invention, an incorrect identification can be avoided in the event the image of a car-plate is blurred, and the characters is deformed or smeared.
