  • Patent number: 11923663
    Abstract: In the spark plug heat rating measurement method and system based on spark discharge current active heating, the spark plug is installed in a constant-temperature water jacket cooling chamber with a specific torque. A constant spark discharge current control module is connected to the high-voltage terminal of the spark plug, to provide real-time controlled discharge current to heat up the high-voltage central electrode of the spark plug. During the spark discharge process, the temperature change of the high-voltage central electrode and the surrounding ceramic insulator are measured by a temperature detection module and used to determine the heat rating of the spark plug. By real time adjusting the discharge current level of the spark plug, or providing a same amount of spark energy to the spark gap, the heat ratings of spark plugs with different ceramic insulation structures can be evaluated through the temperature changes during discharge or after discharge.

  • Patent number: 11879920
    Abstract: Toroidal high dielectric ceramic microwave tuning probes are sliding on the central conductor of a high power electro-mechanical microwave dual-probe coaxial load pull tuner and create high reflection factor over a wide frequency range. The probes are positioned horizontally using a remote translation mechanism and allow continuous coverage of the Smith chart over a high frequency and VSWR (reflection factor) range. A remotely adjustable attenuator is inserted adjacent to the test port and mitigates spurious high reflection. A de-embedding calibration allows full tuner characterization in a few minutes instead of several hours.

  • Patent number: 11878181
    Abstract: An erythrocyte de-aggregation system includes a band, including a strap and housing securing an iron-cored, micro-coil to an appendage, such as a wrist, of a subject to apply a PEMF into a target vessel in the vascular system of the subject. Typically, all of the blood circulates about the body within a matter of a few minutes, some within seconds, thus treating the entire bloodstream over time. The portable PEMF system intensifies both the concentration of electromagnetic flux per unit area, as well as the depth of penetration into the body. The portable PEMF systems relies on the body's circulatory system to eventually pass the body's entire volume of blood past it over a period of time.
