Abstract: This disclosure provides an EEG decoding method based on a non-negative CP decomposition model. The method extracts time component characteristics of the EEG of the different subjects in the boundary avoidance task, optimizes a characteristic dimension by using a 2-DPCA, and takes classification by using a support vector machine, so that differences of the EEG of subjects in different states can be reflected, and the EEG classification of the single subject has a great accuracy. The time component characteristics of the EEG can be obtained by using the channel components and the frequency components based on the non-negative CP decomposition model and by means of the interaction between the EEG modes. The characteristics of the obtained EEG time components have good separability, and the dimensions of the characteristics are optimized, so that the EEG of left and right hand movements in the boundary avoidance tasks can be effectively decoded.

Abstract: A double-field coupling dehydrator and an optimization method for parameters. Parameters to be optimized is determined. Simulations to the double-field coupling dehydrator is carried out according to the parameters to be optimized, individually. Optimal ranges of the parameters to be optimized are determined according to simulation results. Optimized parameter combinations of the parameters to be optimized are determined separately. Separation efficiencies of the double-field coupling dehydrator under different optimized parameter combinations are obtained to determine an optimal parameter combination. The method considers both influences of single parameters and interactions between the parameters on the separation efficiency. Based on numerical simulation results of the double-field coupling dehydrator, these influences are analyzed by a software Design-Expert to obtain an optimal parameter combination.

Abstract: An image generation system is provided, the system generating an ultrasound image and a photo-acoustic image of an object and including a dual-wavelength laser source, an optical filter, and an optical-based ultrasound sensor. The laser source generates a first laser pulse with a first wavelength or a second laser pulse with a second wavelength. The optical filter almost completely absorbs the energy of the first laser pulse and by the photo-acoustic effect, generates and transmits an ultrasound to the object so the object scatters and reflects the ultrasound. The second laser pulse almost completely penetrates the optical filter and is transmitted to the object so the object absorbs the energy of the second laser pulse, generates and sends a photo-acoustic signal. The optical-based ultrasound sensor receives the ultrasound and the photo-acoustic signal to generate the ultrasound image and the photo-acoustic image of the object.

Abstract: An imaging probe is suitable to be inserted into a tubular object so as to detect an interior image of the tubular object. The imaging probe includes a light source excitation assembly, an ultrasonic transducer and a receiver. The light source excitation assembly includes a pulsed laser, a first optical fiber and a cone-shaped reflecting member. The pulsed laser is suitable to generate a pulsed light energy. The cone-shaped reflecting member is suitable to reflect the pulsed light energy to let the pulsed light energy annularly irradiate the inner wall of the tubular object so as to produce a photoacoustic signal. The ultrasonic transducer is suitable to generate an ultrasonic signal. The ultrasonic signal annularly irradiates the inner wall of the tubular object so as to produce an ultrasonic echo signal. The receiver receives the photoacoustic signal and the ultrasonic echo signal.
