Abstract: Provided a video processing method, a device and electronic equipment, which can process a video including multiple human body objects to obtain a plot video segment for any one of the multiple human body objects. The embodiments of the present application can carry out pertinent observations on the human body objects and improve the sensory experience of video viewers. The video processing method includes obtaining a first video including multiple human body objects; determining a detection region of a first object among the multiple human body objects according to at least one image frame of the first video; performing human behavior feature detection on the detection region of the first object in the first video to obtain a first plot video segment of the first object in the first video.

Abstract: A device for automatically mixing powder for injection, includes an injector body, a solvent bottle, a needle, a first impelling unit and a second impelling unit. The injector body has a solute bottle and its mouth is opposite the mouth of the solvent bottle. The first impelling unit is disposed upon the solvent bottle. The second impelling unit is sleeved with a needle and located between the mouth of solute bottle and mouth of solvent bottle. A first and a second impelling sleeve-are driven by the solvent bottle to slide along the solute bottle, so the first end of the needle is fixed and extend through the solute bottle. The solvent bottle drives the first impelling sleeve and second impelling sleeve to turn with each other. The second impelling sleeve slides opposite the first impelling sleeve to make the second end of the needle extend through the solvent bottle.

Abstract: A communications device and method for secure group communications in a highly dynamic environment permits group members to be readily added or removed from the group without compromising security. The communications device includes an orthogonal code generating module, an orthogonal code table, an encryption module and a decryption module. Group members exchange orthogonal codes with each other so that each member has a set of orthogonal encryption and decryption codes assigned by each of the other group members. A message sender may broadcast an amalgamated message assembled from a number of individually encrypted messages for different group members. A recipient extracts their message by decrypting the amalgamated message using the orthogonal decryption code received from the sender. Parts of the amalgamated message encrypted for other group members are transparent to the recipient.
