Abstract: An exchangeable in-pipe power generating device includes a pipe unit, a base unit, and a power generating unit. The pipe unit includes a pipe body extending along a pipe axial direction, and an opening disposed on the pipe body and extending along the pipe axial direction. The base unit includes a first base portion extending along the pipe axial direction, disposed in the pipe body, and adjacent to the opening. The power generating unit includes a plurality of power generators disposed on the first base portion and spaced apart from one another along the pipe axial direction. Each of the power generators includes a blade module rotatable about a blade axis, and a power converting module driven by the blade module to convert kinetic energy into electrical energy. The blade axis of each of the power generators cooperates with the pipe axial direction to form an acute angle.

Abstract: Disclosed are an unlocking apparatus, a swapping device comprising same, and an unlocking control method. The unlocking apparatus is used for unlocking or locking a battery box in a battery bracket on an electric vehicle, and comprises a drive mechanism, an unlocking component, and a transmission member. The drive mechanism drives the unlocking component to move by means of the transmission member, so that the unlocking component drives a locking mechanism on the battery bracket to move to unlock or lock the battery box; the unlocking component is axially rotatable relative to the transmission member to adapt to the angle deviation between the unlocking component and the standard unlocking position on the battery bracket. The swapping device comprises the unlocking apparatus. In this way, even if there is a circumferential deviation, the unlocking component is ensured to be accurately aligned and connected.

Abstract: A method for categorizing and adjusting an orientation of a clinical image is implemented using a system that includes a categorization module and a plurality of orientation modules. The method includes: in response to receipt of the clinical image, performing, by the categorization module, a categorization operation so as to categorize the clinical image into one of a plurality of predetermined categories; transmitting the clinical image to a corresponding one of the plurality of orientation modules based on a result of the categorization operation; and performing, by the corresponding one of the plurality of orientation modules, an orientation adjusting operation for adjusting the orientation of the clinical image. For a clinical image that is a facial image and for a clinical image that is an intra-oral image, different orientation adjusting operations may be performed, so as to generate an adjusted image that is properly oriented.
