  • Publication number: 20190196448
    Abstract: The present invention provides a method for simulating daylight performance of buildings based on regional daylight climate data. The method comprises the steps of: establishing a regional sky luminance distribution database from measured data; mapping sky luminance data to an artificial sky lamp group; using a 3D printing machine to fabricate a scaled physical model based on real parameters of the building to be simulated; and using the scaled physical model in the artificial sky integrated with regional sky luminance distribution data to make the daylight performance simulation. This method can achieve high-precision simulation of the daylight performance of buildings by using regional sky daylight climate data with a highly accurate physical model of the building.

  • Publication number: 20180088048
    Abstract: The devices, methods, and systems of the present disclosure provide for spectroscopic super-resolution microscopic imaging. In some examples, spectroscopic super-resolution microscopic imaging may be referred to or comprise spectroscopic photon localization microscopy (SPLM), a method which may employ the use of extrinsic labels or tags in a test sample suitable for imaging. In some examples spectroscopic super-resolution microscopic or spectroscopic photon localization microscopy (SPLM) may not employ extrinsic labels and be performed using the intrinsic contrast of the test sample or test sample material. Generally, spectroscopic super-resolution microscopic imaging may comprise resolving one or more non-diffraction limited images of an area of a test sample by acquiring both localization information of a subset of molecules using microscopic methods known in the art, and simultaneously or substantially simultaneously, acquiring spectral data about the same or corresponding molecules in the subset.

  • Patent number: 9930582
    Abstract: There is provided mechanisms for determining Universal Terrestrial Radio Access (UTRA) environment for a wireless terminal (WT). The WT supports operation in both a UTRA frequency-division duplexing (UTRA-FDD) environment and a UTRA time-division duplexing (UTRA-TDD) environment. The WT acquires a need for determining its UTRA environment. The WT determines its UTRA environment based on network information received by the WT. The network information indicates if the WT is in the UTRA-FDD environment or in the UTRA-TDD environment.

  • Patent number: 9854540
    Abstract: A mobile communication device and a radiated power adjusting method thereof are provided. The mobile communication device includes an antenna, a signal measurement module, a proximity sensing module and a controlling module. The antenna receives a radio-frequency signal, and the signal measurement module is coupled to the antenna and measures a signal parameter of the radio-frequency signal. The proximity sensing module is switched between an activation mode and an original detection mode according to existence of an object, wherein a sensing conductor is configured adjacent to an adjusted antenna. The controlling module is coupled to the signal measurement module and the proximity sensing module, and the controlling module adjusts the radiated power of the adjusted antenna. When the signal parameter decreases more than a threshold value and the proximity sensing module is in the activation mode, the controlling module reduces the radiated power of the adjusted antenna.
