Abstract: In an electronic parking braking system and a control method thereof, the system includes a transmission apparatus, a main parking braking controller and an auxiliary parking braking controller. The transmission apparatus sends a parking request signal when a parking (P) stage is input. The main parking braking controller determines whether being capable of performing a main parking braking control upon receiving the parking request signal, performs the main parking braking control upon determining that the main parking braking controller can perform the main parking braking control, and sends a failure signal to the transmission apparatus upon determining that the main parking braking controller cannot perform the main parking braking control. When the transmission apparatus receives the failure signal, the auxiliary parking braking controller may perform an auxiliary parking braking control.

Abstract: An optical coherence tomography scanning system traverses its respective scan pattern quickly, typically completing an entire two-dimensional frame faster than a conventional raster scanner completes one raster line segment. To traverse the scan pattern quickly, the system takes fewer A-scans per length of scan pattern than a conventional OCT scanner. To compensate for the sparsity of the sample points along the respective scan line segments, and for gaps between respective line segments of the trajectory, the system acquires and combines several partially overlapping frames for each study to generate a dense OCT image. A visible light camera captures an image for each traversal of the scan pattern, but only a predetermined subset of pixels in the visible light image, which correspond to locations on the anatomical item interrogated by a sample arm of the OCT, are used to color corresponding pixels in the dense OCT image.

The method includes that: speech data of each of a plurality of training samples is inputted into a teacher model and a to-be-trained speech recognition model separately. Additionally, an embedding outputted by the teacher model and encoded data outputted by the to-be-trained speech recognition model are obtained.
