  • Patent number: 10564213
    Abstract: A method and system of monitoring a reliability of a semiconductor circuit are provided. A current consumption of a first ring oscillator that is in static state is measured at predetermined intervals. Each measured current consumption value is stored. A baseline current consumption value of the first ring oscillator is determined based on the stored current consumption values. A latest measured current consumption value of the first ring oscillator is compared to the baseline current consumption value. Upon determining that the latest measured current consumption value is above a threshold deviation from the baseline current consumption value, the first ring oscillator is identified to have a dielectric breakdown degradation.

  • Patent number: 10527646
    Abstract: An electrical contact assembly comprised of four identical modules arranged in a four-sided formation. Each module comprises of a bottom housing formed with two rows of through holes to allow a row of front and back contact pairs to be inserted, with separators in between each pair to prevent electrical conductance between the pairs. A top housing is then lowered onto the top of these contact pairs. With the aid of a key tool, the rows of contact pairs are inserted into through holes in the top housing. By virtue of different heights between the front and back rows of through holes, the front and back contact rows are inserted one first, and then the other. This allows for easier installation of an assembly with minimal tolerance accumulation.

  • Patent number: 10488544
    Abstract: In a system for arranging survey points in field operation with a ground electromagnetic instrument, the position information of survey lines and survey points are planned and downloaded to an aircraft in advance. The survey lines and one survey point among survey points planned in advance is selected and the coordinate information of the survey point is acquired. The aircraft is controlled to fly to the physical geographic location of the survey point according to the coordinate information of the survey point in conjunction with positioning information acquired in real time. The aircraft hovers above the physical geographic location of the survey point and projects a predetermined indication mark to the ground. The detection instrument and electric field sensor are deployed at a first position indicated by the indication mark, and the magnetic field sensor is deployed at a second position; such a process is repeated till all of the planned survey points are arranged.

  • Patent number: 10436931
    Abstract: Electromagnetic sensors which provide high coupling gain between the transmitter and receiver of a dielectric tool include a conductive pad having a cavity filled with dielectric filler, and an electrical conductor that provides electrical current to a conductive feeder placed inside the dielectric filler. During operation, current is fed to the conductive feeder to thereby produce an electric monopole that feeds electromagnetic power into the cavity, which then radiates out into the formation as electromagnetic signals. Because of the design of the electromagnetic sensors, the transmitter/receiver coupling gain and SNR are optimized over the entire range of the dielectric constant (i.e., 5??r?80).
