  • Patent number: 12266929
    Abstract: The present disclosure provides a data acquisition and control system of pulsed power supply for multi-load, and relates to the technical field of pulsed power. The system of the present disclosure is configured to control 18 sets of pulsed power supplies to provide 18 coils with stable and reliable excitation current featuring multiple output time sequences and flexible adjustability, such that a near-earth space plasma environment ground-based simulation device can simulate the magnetic field topology of the earth magnetosphere and realize a background magnetic field required by physical experiments. The system mainly achieves the following functions: control over charge and discharge of pulsed power supplies, selection of power supplies put in use, “delay trigger” setting, voltage monitoring, status monitoring of key components and output current display; and it is also necessary to realize failure alarm and failure handling for the purpose of ensuring the safety of equipment and personnel.

  • Publication number: 20250049883
    Abstract: Described herein are improvements relating to IGF-1 function analysis, adjustment and its application in disease management of non-neurological and/or neurological conditions. More specifically, methods relating to the clinical application of cyclic glycine-proline (cGP) and/or cGP/IGF-1 molar ratio as the plasma biomarker for prediction of risk and recovery of non-neurological and/or neurological conditions with IGF-1 dysfunction and the use of a cGP containing animal, marine or fungal based material such as concentrate/extract of hydrolysed bovine collagen and marine collagen, mushroom and seaweed along with plant-based cGPMAX™ for the treatment of same. The methods more accurately measure IGF-1 function in vivo indirectly using cGP and cGP/IGF-1 molar ratio along with a means to adjust and normalise cGP and cGP/IGF-1 molar ratio (and hence active IGF-1 concentration), and specific treatment methods for individuals with a lower or reduction of cGP level relative to a standard set of baseline data.

  • Publication number: 20240385449
    Abstract: An optical combiner and a display device are provided. The optical combiner includes a light-transmitting structure and a waveguide structure in the light-transmitting structure. The waveguide structure includes a first dielectric layer, a waveguide plate, and a second dielectric layer arranged in sequence. The waveguide plate includes a coupling-out region, wherein the refractive index of the first dielectric layer and the refractive index of the second dielectric layer are both less than the refractive index of the waveguide plate. Since the refractive index of the first dielectric layer and the refractive index of the second dielectric layer are both less than the refractive index of the waveguide plate, light beams propagating in the waveguide plate undergo totally reflection during propagation and cannot be refracted into the first dielectric layer and the second dielectric layer.

  • Publication number: 20210133683
    Abstract: Techniques are provided for implementing a probabilistic system and architecture to predict and optimize particular user activity. In one technique, opportunity application data that indicates multiple applications to multiple opportunities is stored. Tracking data that indicates, for each opportunity, a number of reviewer actions with respect to applications to the opportunity is stored. Based on the tracking data, one or more machine learning techniques are used to learn parameters of a model that takes, as input, a number of weighted applications of an opportunity and generates, as output, a prediction of a confirmed hire for the opportunity. A particular opportunity is identified and a first number of reviewer actions with respect to the particular opportunity is determined. A second number of weighted applications for the particular opportunity is generated based on the first number. The second number is input into the model to generate a score for the particular opportunity.
