Abstract: An optical communication device includes two optical transmitting devices, two optical receiving devices, an optical path component, and an optical fiber adapter. A first converging lens packaged in each of the optical transmitting devices converges a light beam emitted by a light source, and provides the converged light beam for the optical path component. A second converging lens packaged in each of the optical receiving devices converges a light beam from the optical path component, and provides the converged light beam for a photoelectric detection element. The optical path of the optical communication device is simplified and the process costs are reduced. In addition, the quantity of used lenses is reduced, correspondingly reducing the quantity of optical coupling dimensions between mechanical parts and improving production efficiency of combined passive optical network (Combo PON) products.

Abstract: The present invention provides an underwater image color restoration method. In the method, 8-bit RGB pixel values of pixels in an underwater image are converted to a linear sRGB space for adjustment processing, adjusted pixel values are converted to 8-bit RGB pixel values, and then the acquired 8-bit RGB pixel values are fused with the adjusted pixel values to obtain a restored underwater image. Therefore, a foreground object in the underwater image or an underwater video processed using the solution of the present invention is natural and rich in color; in addition, the natural blue and green colors of background seawater are preserved, and the viewing effect of an entire picture is improved significantly and is comparable to or even better than the effect that can be achieved in the past after considerable manual toning.

Abstract: The present invention relates to the field of detection of dimethyltryptamine. In order to solve the problems in the prior art that liquid chromatography-tandem mass spectrometry for detection of dimethyltryptamine has high requirements for instruments and operators and is difficult to popularize and low in detection speed, the present invention discloses a dimethyltryptamine hapten, an artificial antigen and preparation methods and application thereof. The dimethyltryptamine hapten is obtained by a reaction of N,N-dimethyl-5-hydroxytryptamine as a precursor and glutaric anhydride. The artificial dimethyltryptamine antigen obtained from the dimethyltryptamine hapten can be used for preparing a dimethyltryptamine monoclonal antibody and a dimethyltryptamine colloidal gold-fluorescence test paper.

Abstract: According to examples, an apparatus may include a processor and a memory on which are stored machine-readable instructions that when executed by the processor, may cause the processor to track traffic events and user interface (UI) events in parallel and record a first event of a hybrid test script. The first event may be recorded in a traffic mode to record one or more of the traffic events. The processor may transition from the traffic mode to a UI mode and, responsive to the transition from the traffic mode to the UI mode, may share session data between the traffic events and the UI events. Based on the session data, the processor may record a second event of the hybrid test script in the UI mode.
