Terahertz full-duplex co-local oscillator solid-state front-end transmitting circuit

A terahertz full-duplex co-local oscillator solid-state front-end transmitting circuit is disclosed, which belongs to the technical field of terahertz communication. The overall structure of the solid-state front-end transmitting circuit adopts a new system, wherein the circuit comprises two branches that are parallel and driven by a local oscillator source. A branched waveguide directional coupler is configured to output two driving signals provided by the same local oscillator source respectively to two branch circuits with required powers. Two transmission signals generated from the two branches are combined into one signal for transmission through an orthogonal mode coupled duplexer, so as to fulfill the construction of a full-duplex co-local oscillator solid-state front-end transmission circuit.

Video type detection method and apparatus based on key frame, and storage medium

The present application discloses a video type detection method, apparatus, electronic device and storage medium. A specific implementation solution is as follows: obtaining N key frames of a first video, where N is an integer greater than 1, and a type of the first video is to be detected; obtaining M confidence scores corresponding to each of the N key frames by inputting each of the N key frames into M algorithm models corresponding to the first video type respectively, where M is an integer greater than 1; determining a confidence score of the first video by a fusion strategy algorithm model according to N×M confidence scores of the N key frames; and comparing the confidence score of the first video with a confidence score threshold corresponding to a first video type, to determine whether the type of the first video is the first video type or not.

Split-type automatic lifting bracket device and sanitary product

The present disclosure provides a split-type automatic lifting bracket device and a sanitary product. The split-type automatic lifting bracket device comprises an upper bracket assembly and a lower bracket assembly, wherein the upper bracket assembly is used for bearing a water receiver or a waterway control valve; and the lower bracket assembly is used for bearing or supporting and driving a sanitary product to rise and descend, and comprises a self-supporting leg assembly, an auxiliary standing device, an automatic lifting control device, a lifting bracket, a push-pull power device, a rolling guide device, and the sanitary product. The lifting structure of the present application can rise and descend automatically without an additional force to assist in height adjustment. The water receiver and other structures are not provided on the lifting bracket, so that a weight for the lifting structure to rise is reduced.
