Abstract: The present disclosure provides an extracorporeal focused ultrasound treatment device for a pelvic disease. The treatment device includes an ultrasonic transducer and a treatment couch. Sound emitting surface of the ultrasonic transducer is a spherical surface having a first notch, a second notch and a third notch, the first notch and the second notch are respectively positioned at two intersections of the spherical surface and a diameter perpendicular to the main great circle, and the third notch connects the first notch with the second notch; a cross-section of the sound emitting surface parallel to the main great circle is in a shape of an arc; and an ultrasonic wave generated by the sound generation unit is focused at a center of the sphere corresponding to the sound emitting surface. The treatment couch is configured for a human body to lie in a lithotomy position.

Abstract: The present invention provides for an ice-nucleating particle for cloud seeding and other applications, which can initiate ice nucleation at a temperature of ?8° C. Further, the ice nucleation particle number increased continuously and rapidly with the reducing of temperature. The ice nucleating particle in the present invention is a nanostructured porous composite of 3-dimensional reduced graphene oxide and silica dioxide nanoparticles (PrGO-SN). The present invention also provides for a process for synthesizing the PrGO-SN.

Abstract: A male wire connector system with lock mechanism, comprising: a housing assembly; a plug assembly moveably connected to the housing assembly; a jack assembly within the plug assembly comprising a plurality of terminals attached to a stopper mounted at the end thereof; a metal body assembly within the housing assembly and connected with the slide assembly and the cable wire; a cable extended from the housing assembly; and a slide assembly disposed on the top of the jack assembly slidable between the plug assembly and the cable within a predetermined distance by manipulation. The slide assembly is mechanically engaged with the plug assembly, the jack assembly, the metal body assembly, the housing assembly and the wire, triggering the forward and backward movement of the plug assembly. The male wire connector system can be securely locked or easily released from the female receptor when user manipulates the housing assembly.
