Abstract: The invention provides an atrial fibrillation risk prediction system based on heartbeat rhythm signals. A heartbeat rhythm signal preprocessing module obtains heartbeat interval sequence data by calculating the time interval of two adjacent heartbeats. During sample labeling, a positive sample is from heartbeat interval data during the sinus heart rate period of a case with high AF risk, and a negative sample is from heartbeat interval data of a case with low AF risk; and an atrial fibrillation risk prediction model is trained with positive and negative samples and is used to test heartbeat interval data, an AF risk curve between the proportion of positive samples and output probability thresholds is obtained according to the output probabilities of testing samples, the area under the AF risk curve is calculated as the atrial fibrillation risk value, and the value can reflect the atrial fibrillation risk.

Abstract: Disclosed is directed to a moving object detection apparatus and method. The apparatus comprises an image capture module, an image alignment module, a temporal differencing module, a distance transform module, and a background subtraction module. The image capture module derives a plurality of images in a time series. The image alignment module aligns the images if the image capture module is situated on a movable platform. The temporal differencing module performs temporal differencing on the captured images or the aligned images, and generates a difference image. The distance transform module transforms the difference image into a distance map. The background subtraction module applies the distance map to background subtraction technology and compares the results with the current captured image, so as to obtain the information for moving objects.

Abstract: A method of TFT (Thin Film Transistor) manufacturing and a substrate structure are provided. The structure includes a substrate and a self-alignment mask. A self-alignment mask on a substrate is first manufactured and then the self-alignment mask may synchronously extend with the substrate during the thermal process. When an exposure light source is provided on the side without a TFT formed, the self-alignment mask can overcome the problem that when a plastic substrate extends, the positions of the source and drain to be formed on the plastic substrate are incorrect, which has a great effect on the accuracy of alignment. As the result, the positions of the source and drain can be defined accurately.

Abstract: A generator (6) directs microwave signals to a waveguide (1) having a linear array of slots (2), and the signals are received by measuring device (5). The local permittivity or moisture content of material adjacent the waveguide (1), such as a stack of timber, may be determined at each slot (2) via regression analysis. The total permittivity or moisture may be determined by averaging measurements obtained for both transmission directions of the waveguide (1). The apparatus may be used for controlling drying parameters, such as drying time, for the material.
