  • Patent number: 10310116
    Abstract: The present invention relates to a method for determining a stacked model describing architectural elements from a plurality of architectural element. The method comprises selecting an architectural element, determining merged zone, the merged zone being function of the zone of the selected architectural element and zones of related architectural elements, determining a probabilistic zone, the probabilistic zone being a function of the merged zone, and determining a probabilistic superposition value associated with the determined probabilistic zone, the probabilistic superposition value being a function of the superposition value of the selected architectural element. The previous steps are repeated for each architectural element in the plurality of architectural elements. The method further comprises stacking every determined probabilistic zone in a stacked model according to the determined probabilistic superposition value associated therewith, and providing the stacked model.

  • Patent number: 10228489
    Abstract: The present invention discloses a method for detecting glacier melting based on tracer technology. The method includes the following steps. 1. Different tracer agents with equal concentration are respectively added into a plurality of water samples. The water sample and the tracer agents are mixed well. Meanwhile, the volume and the mass of each glacier model are recorded. A plurality of water samples added with tracer agents are frozen layer by layer from inside to outside to establish a plurality of glacier models. 2. The surrounding environmental factors of the glacier model are adjusted. Water samples of the glacier models melted under different environmental factor conditions are collected. Furthermore, the concentrations of different kinds of tracer agents in the water samples are measured.

  • Patent number: 10228411
    Abstract: A circuit board testing apparatus detects sparking and partial discharge between wiring patterns on a circuit board to determine if the circuit board is defective. A constant current source feeds a constant current to a wiring pattern to be tested. A voltage measurement part measures the resulting voltage at the wiring pattern. A normal state voltage gradient calculation part calculates a voltage gradient in a normal state where there is no sparking or partial discharge. A determination part determines whether the voltage gradient remains invariant, by comparing voltage measurement results within a predetermined range with an estimated value of the voltage based on the voltage gradient in the normal state. The determination part determines whether a circuit board is defective, on the basis of whether the voltage gradient remains invariant.

  • Patent number: 10168440
    Abstract: A method for determining an optimum spacing of seismic energy sources based on mutual admittance includes deploying a plurality of seismic energy sources along a source line, separated by a selected spacing. Seismic receivers are deployed along a receiver line orthogonal to the source line. Seismic energy is simultaneously transmitted from each of the plurality of seismic energy sources while recording signals from the seismic receivers. The transmitting and recording of signals is repeated for a plurality of different spacings between the energy sources. Seismic energy in the recorded signals is determined in separate time windows selected to represent reflected body wave signal, and source generated ground roll noise, respectively. A signal-to-noise ratio with respect to the spacing of the seismic energy sources is calculated and the optimum spacing between energy sources is selected based on the signal-to-noise ratio.

  • Patent number: 10161735
    Abstract: An apparatus for determining the position of the rotor of an electric machine in relation to the stator. The machine has multiple phases, each of which includes at least one pole winding with a magnetizable core. The apparatus includes devices for detecting measurement signals that are characterized by the momentary degrees of magnetization of the pole winding cores. The degrees of magnetization are influenced by the angular position of the magnetic field of the rotor. The devices are also used to detect the currents in the phases and determine the angular position of the rotor from the detected measurement signals, taking into account a contribution of the phase currents to the degrees of magnetization of the pole winding cores.
