  • Patent number: 11913986
    Abstract: A reliability evaluation method and system for a microgrid inverter IGBT based on segmented long short-term memory (LSTM) is disclosed, including steps as follows. An electrothermal coupling model is constructed to obtain real-time junction temperature data. The original LSTM algorithm is improved to obtain a segmented LSTM prediction network for the aging characteristics of the IGBT. The monitoring value of the IGBT aging parameter is used to perform segmented LSTM prediction to obtain the predicted aging process, and the threshold values of different aging stages are categorized. An aging correction is performed on the aging parameter of the electrothermal coupling model to ensure the accuracy of the junction temperature data. Rainflow-counting algorithm is used to calculate real-time thermal stress load distribution of the IGBT. The fatigue damage theory and the Lesit life prediction model are combined to calculate the real-time cumulative damage and predicted life of the IGBT.

  • Patent number: 11904959
    Abstract: Systems and methods are provided for detecting water within an electronic power steering assembly. A sensor assembly includes a resistor and a water-sensitive capacitor arranged to provide a series resistor-capacitor (RC) network having a cut-off frequency that is a function of a capacitance of the water-sensitive capacitor. An oscillator provides an excitation to the series RC network having a known frequency, such that the series RC network provides an output in response to the excitation. An envelope detector receives the output of the series RC network and generates an output representing an amplitude of the output of the series RC network. A microcontroller determines if water is present within the electronic power steering assembly from the amplitude of the output of the series RC network.

  • Patent number: 11879921
    Abstract: Coaxial load pull tuners use one horizontally-only moving metallic reflective probe inserted in the slabline at fixed penetration and an adjustable RF energy absorbing eccentrically into the slabline rotated disc. The tuner does not use high precision vertical axes. The remotely adjustable attenuator is inserted adjacent to the test port and mitigates spurious high reflection.

  • Patent number: 11848153
    Abstract: A periodic arrangement of magnets are used to form structures that channel the potential energy that a magnet possesses into kinetic energy in a controlled fashion to perform some useful work or function. One function is to create a magnetic chute that converts the potential energy of a magnetic projectile into kinetic energy that is used to channel the projectile to follow a path achieving high velocities along a path. The path is formed by assembling magnets periodically along the path in a certain fashion to create a magnetic chute that allows the magnetic projectile to slide easily along the path since the projectile is confined by the shape of the magnetic chute.

  • Patent number: 11842840
    Abstract: An inductive transducer apparatus for testing metallic objects using Pulsed Eddy Current topology. The Apparatus includes a transmitter coil, a receiver coil, and a hybrid core. The hybrid core has a high saturation point which allows the transducer to generate a strong initial magnetic field that may further induce strong eddy currents on the surface of the target capable of penetrating deep into metallic objects under inspection. The hybrid core also has a high permeability which enhances the transducer's sensitivity and allows to maintain high signal-to-noise-ratio and of the received signal associated with Eddy Current magnetic field decaying, thus enhancing the system's performance in environments where reliable quantitative analysis of flaws located deep underneath the surface of metal objects is required. A linearity compensation method may be applied to further enhance the performance of the system.
