  • Patent number: 11224942
    Abstract: A method for stack-welding dissimilar metal members by placing a first metal member and a second metal member having a melting point higher than that of the first metal member on top of one another and performing laser welding is provided. The second metal member is placed on the first metal member, and a molten pool in which only the second metal member is melted is formed by applying a laser beam for thermal-conduction welding from above the second metal member. After the molten pool comes into contact with the first metal member and hence the first metal member melts in the molten pool, the molten pool solidifies, so that the first and second metal members and are welded together.

  • Patent number: 11224102
    Abstract: In a solid-state heating system, once a load with specific load characteristics has been placed in a heating cavity, a processing unit produces control signals that indicate an excitation signal frequency and one or more phase shifts, which constitute a combination of parameter values. Multiple microwave generation modules produce RF excitation signals characterized by the frequency and the phase shift(s). Multiple microwave energy radiators radiate, into the heating cavity, electromagnetic energy corresponding to RF excitation signals received from the microwave generation modules. Power detection circuitry takes reflected RF power measurements, and the processing unit determines a reflected power indication based on the measurements. The process is repeated for different combinations of the parameter values, and an acceptable combination of parameter values is determined and stored in a memory of the heating system.

  • Patent number: 11210967
    Abstract: Various embodiments are directed to a central executive training (CET) platform that targets central executive processes, rather than short term memory. Central executive deficits have been linked experimentally and developmentally with Attention Deficit Hyperactivity Disorder (ADHD) symptoms and impairments. Unfortunately, substantial evidence indicates that conventional working memory training programs fail to improve these symptoms and impairments. This discrepancy may reflect insufficient targeting, as extant protocols focus on short term memory and do not adequately engage the specific central executive components linked with the disorder's behavioral and functional impairments.
