A method and an apparatus for warning of emergency vehicles in emergency service. The emergency vehicles use vehicle-to-vehicle communication to transmit warning messages which are received by other vehicles and are indicated to the driver of the receiving vehicle. In order to allow rapid orientation of the driver, provision is made for the warning message from the emergency vehicle to have a position statement for the emergency vehicle and for the position statement to be evaluated in the vehicle which receives the warning message, wherein the position of the emergency vehicle is indicated relative to the position of the receiving vehicle.

A socket assembly includes a body having a driving portion to be driven by a driving tool and a transmission portion for driving a fastener. The transmission portion includes a first end and a second end spaced from the first end along a longitudinal axis. The first end of the transmission portion is connected to the driving portion. A sleeve is mounted around the second end of the transmission portion. A jacket is mounted around the transmission portion and the outer periphery of the sleeve. The transmission portion of the body and an outer periphery of the sleeve are visible through outer and inner peripheries of the jacket.

The invention provides a display screen structure. The display screen structure comprises a display module and a light reflection prevention module; the light reflection prevention module is fixed on one side of the display module; the light reflection prevention module comprises a plurality of refraction structures which are connected sequentially; each refraction structure comprises a connection part and a plurality of refraction parts which are connected with two sides of the connection part; and the outer surfaces of the refraction parts and the outer surface of the connection part form included angles so as to form a scraggly light reflection structure.

A snow gliding board, integrating a structure element incorporated in a raised end of said gliding board, said element having a plurality of hollowed through openings between its upper and lower surfaces, distributed across its surface, wherein said element comprises in said raised end at least one region free of through openings, separating two areas having through openings, the width of said region being greater than the shortest distance between two through openings in the areas separated by said region.

A device for freeze preservation of a human ovarian tissue under liquid nitrogen comprises a pipe body; one end of the pipe body is provided with an opening, the opening is equipped with a sealing cover, the sealing cover and the pipe body can be detachably connected, and a sealed storage space is enclosed by the sealing cover and the pipe body; the inner top surface of the sealing cover is provided with a forking device for forking the human ovarian tissue. The forking device comprises a plurality of fine needles which are arranged in parallel, and fixed ends of the fine needles are vertically fixed on the inner end surface of the sealing cover, free ends of the fine needles extend to the pipe body along the axial direction of the pipe body. The forking device comprises 3 fine needles, the 3 fixed ends of the 3 fine needles are in head-to-tail connection to form a regular triangle, and the circle center of the inner end face of the sealing cover is the center of the regular triangle. The device is simple in structure and easy to use; the forking device can avoid physical damage of blind clipping with forceps under liquid nitrogen on an ovarian follicle enriched cortical part in the ovarian tissue, and also avoids cross contamination with other iatrogenic substances in a liquid nitrogen tank.
