  • Patent number: 11402541
    Abstract: A system and method for forecasting perceived transitions to the four annual seasons in geographic areas is disclosed. The perceived transitions are identified by comparing forecasted daily temperatures in each geographic area to thresholds generated based on normal daily temperatures in those geographic areas. The forecasted daily temperatures may be calculated using both forecasted temperatures and forecasted perceived ambient temperatures (calculated using both temperature and humidity, cloud cover, sun intensity, and/or wind speed).

  • Patent number: 11385297
    Abstract: An electrical leakage determination system determines if an electrical leakage occurs between each of power supply paths and a grounding section. The electrical leakage determination system includes a coupling capacitor with one end connected to an anode-side power supply path, a resistor connected to the other end of the coupling capacitor, and an oscillator connected to the resistor to output an AC voltage to the resistor. A determiner detects a voltage at a connection point located between the coupling capacitor and the resistor when the oscillator outputs an AC voltage to the resistor. The determiner determines if the electrical leakage occurs based on the detected voltage. The oscillator increases an absolute value of an AC voltage output during a preparation period provided prior to a detection timing when a voltage is detected at a connection point greater than an absolute value of an AC voltage output at the detection timing.

  • Patent number: 11378705
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, to generate a custom seismic surface and volume attribute. In one aspect, a method includes receiving a seismic cube and a seismic surface, and the seismic cube includes traces recorded at receivers deployed to collect seismic data. The seismic surface is picked on the seismic cube. Seismic wavelets are extracted with a selected length from the seismic cube along an intersection with the seismic surface for each spatial coordinate associated with the seismic surface. A reference wavelet is determined. A surface attribute map is generated based on comparing each of the seismic wavelets to the reference wavelet. A productivity of the seismic surface is evaluated using the surface attribute map.

  • Patent number: 11353624
    Abstract: Calculating a wind speed associated with a return period at a proposed wind turbine site. The method comprises selecting a first set of storms from wind speed measurements measured at the proposed site, and selecting a second set of storms from modelled wind speeds, the modelled wind speeds being estimates of wind speeds at the proposed wind turbine site during the measurement period from a mesoscale data set. A comparison is made of characteristic wind speeds of the first and second sets of storms to determine a correction factor. A third set of storms is selected from an extended set of modelled wind speeds from an extended mesoscale data set, and the correction factor is applied to characteristic wind speeds of the third set of storms to provide corrected wind speeds. A wind speed associated with the return period is calculated from the corrected characteristic wind speeds.

  • Patent number: 11327058
    Abstract: A peak detecting method according to the present invention includes a first peak detecting step (S1) of detecting, with a first detection sensitivity, one or more peaks in object data whose peak is to be detected; and a second peak detecting step (S5) of detecting one or more peaks in the object data with a second detection sensitivity that is different from the first detection sensitivity. With this method, since two kinds of detection are performed at the different detection sensitivities, a shoulder peak (or a non-shoulder peak) candidate can be chosen from peaks that are detected with one of the detection sensitivities but are not detected with the other detection sensitivity, and thus, a shoulder peak can be appropriately detected with ease.
