Abstract: The system and method of duet video creating and advertising of the present invention is a digital platform that provides duet templates for video creators to create duet videos, each duet template is associated with a right template clip selection button, a left template clip selection button, an invitation button and a sponsor button, such that a creator can use the right or left template clip selection button to choose to act as the right or left template clip, use the invitation button to invite someone to create a duet video together, and an advertiser can use the sponsor button to sponsor a template and embed ad to the template, such that a duet video created from a duet template will carry the same embedded ad, and the embedded ad can be shared together with the duet video to other video or social platforms.

Abstract: The System and Method of AI-Powered Combined Video Production of the present invention is a digital platform used by both master clip Creators and scene clip creators. In a preferred embodiment, the platform comprises at least one master clip creating device, an APCV application, at least one scene clip creating device, a scene clip database, a scene clip uploading interface, an AI module, a scene clip searching & selecting module, and a network. The platform uses AI technology to detect the master clip attributes of a master clip, and then use the detected master clip attributes to search a scene clip database and select at least one scene clip its defined attributes match the detected master clip attributes, and then the APCV application will combine the master clip with the selected scene clip to create an APC video. The present invention makes it extremely easy for average people to create high quality tailor-made combined videos.

Abstract: A long range electrified projectile immobilization system is mainly comprised of a launching device, a projectile and a high voltage electric pulse current generator. The projectile has two rotary arms which can rotate around hinges on the projectile head at an arc toward the target, there are two pointed electrodes affixed on the rear end of the two rotary arms, these two pointed electrodes are connected to the high voltage electric pulse current generator by two trailing wires. There is also an electric arc sensitive deploying squib inside the projectile and interlock with the two rotary arms, so that these two rotary arms can not separated from each other until the deploying squib is destroyed or removed from the projectile.
