摘要： A multi-channel biopotential signal acquisition system is disclosed. In the system, a plurality of biopotential channels is corrected for common-mode interference. In one aspect, each biopotential channel includes an electrode for providing a biopotential input signal and an associated amplifier for amplifying the biopotential input signal and providing a biopotential output signal. The output signal is processed in a processor. Each biopotential output signal is passed to a common-mode feedback system, which determines an average common-mode signal and feeds that signal back to each of the amplifiers in each of the biopotential channels to enhance common-mode rejection ratio of the system.

摘要： A driver attention area prediction method includes: S1, acquiring an original driving video of a driver attention area and preprocessing the original driving video, thereby obtaining a processed driving video sequence; S2, constructing a deep learning model through a deep learning keras framework and training the deep learning model to obtain a trained deep learning model; S3, performing area prediction on the processed driving video sequence through the trained deep learning model, thereby obtaining a driver attention area prediction result; and S4, outputting the driver attention area prediction result. Moreover, a driver attention area prediction system includes a driving video acquisition and preprocessing module, a model training module, a model application module and a result output module. Differentiated training can be carried out on driving attentions in LHT and RHT scenes, and driving attentions can be accurately predicted as per scenes and conditions.

摘要： A colonoscopy system that is configured to assist a user in execution of a colonoscopy. The present invention includes a body having a cylindrical center portion wherein the cylindrical center portion consists of a telescopic assembly. Located on opposing ends of the center portion are outer air members wherein the outer air members are operable to be inflated or deflated. Proximate the front end of the body is an image data collection member having a transparent capsule and a communications module communicably coupled to an external computer network. The body includes an outer wall having a plurality of outer air passages and outer water passages. A piston assembly is operably coupled to the rear end of the body and includes a plurality of pistons configured to facilitate introduction of pressurized water and air into the body. The colonoscopy system further is operably coupled to a direct display.
