Abstract: A method for processing gait information can be applied in inertial sensing and intelligent medical technology for Parkinson's disease. The method includes: detecting the motion state of a target object in response to receiving confirmation information indicating that the target object has taken the target medication; when the target object is walking, collecting gait information during straight-line walking; in response to detecting that the target object transitions from straight-line walking to another type of gait, and the number of gait information collections exceeds a predetermined threshold, processing the collected gait information with a target function to obtain gait parameters; and finally sending the gait parameters to a mobile communication terminal for further abnormality detection.

Abstract: Provided are a method for pre-allocating memory, an electronic device, and a medium. The method comprises: attempting to obtain a memory block identifier from a list of idle memory block identifiers for each output from each layer; if the memory block identifier is obtained, storing an identifier of the output and the memory block identifier into a mapping table and deleting the memory block identifier from the list of idle memory block identifiers; or if not obtained, creating a new memory block identifier, storing an identifier of the output and the new memory block identifier into a mapping table, and putting the new memory block identifier into a general list of memory block identifiers; for each input to a current layer, putting a memory block identifier corresponding to the input into the list of idle memory block identifiers if the input is not used as an input to a subsequent layer.

Abstract: The embodiments of the present application provide a method and an apparatus for releasing a video file, which are applied to a server. The method comprises obtaining a video file to be released; selecting a first preset number of video frames in the video file to be released; generating a target video file using the selected video frames; determining a target display position for the target video file in a video preview interface; and storing the correspondence between the target display position and the target video file so that a first terminal logging in the server plays the target video file at the target display position in the video preview interface based on the correspondence. As can be seen, since the first terminal plays the target video file at the target display position in the video preview interface, the user can get more information about the content of the video file to be released from the target video file, so that the user experience is improved.

Abstract: A holding structure (2) in an ultrasonic vibration welding device that welds workpieces by applying ultrasonic waves to the workpieces holds an ultrasonic vibration transmitter (horn) (5) bearing the transmission of longitudinally vibrating ultrasonic waves in holding members (8, 8). The horn comprises a horn body (51) having the length of one-half the wavelength ? of the ultra-sonic vibration. Holding structure (2) includes holders (7x, 7y) having a prescribed volume and thin sheet connectors (6a, 6b) placed at different positions (Pa, Pb) on the horn body (51). The horn body (51) is fixed to holding members (8, 8) by means of the respective holders (7x, 7y).

Abstract: A paint can-clamping device applicable to a double-gyroscopic mixer is disclosed, including a lower supporting plate, left and right guide rails, an upper pressing plate and a locking mechanism. The locking mechanism includes an upper pressing plate-fixing frame, a locking piece and a locking piece spring. The upper pressing plate is connected to the upper pressing plate-fixing frame via a guide pole. A cam structure having a cam handle is mounted in the upper pressing plate-fixing frame, and is cooperated, via a cam pressing mechanism for pressing the locking piece downwardly, with the locking piece such that the locking piece moves away from the V-shaped groove of the guide rail to be in unlocking state, thereby achieving a linear movement of the upper pressing plate along the guide rails.
