  • Patent number: 11402882
    Abstract: An apparatus can include a fan including a control pin. The fan may receive a pulse width modulated (PWM) signal at the control pin. The fan may further control a speed of the fan based on a duty cycle of the PWM signal when the PWM signal is in a first range and, responsive to the duty cycle of the PWM signal being in a second range, transmit information corresponding to the fan to an external controller.

  • 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: 11353610
    Abstract: Seismic data of a subterranean region is received by data processing apparatus. The seismic data includes multiple seismic data points. For each seismic data point, gradients are computed based on the received seismic data and a dip angle is computed based on the gradients for the each seismic data point. The dip angle is smoothed using anisotropic diffusion.

  • Patent number: 11287522
    Abstract: A single space platform with an optical telescope, a spectrometer, and/or a database of stored spectral information may be used to determine the range and/or velocity of natural or artificial resident space objects (RSOs). Relativistic Doppler shift measured from reflected solar photons and/or photons from other emitting source(s) provides information that the space platform can use to determine the relative velocity and the range rate. This information can then be used in combination with the right ascension and declination angles to perform differential correction and obtain an updated orbit.
