The method includes: obtaining a target state characteristic of a target subject in a current viewfinder interface of a terminal; and determining a target voice prompt message corresponding to the target state characteristic.

Abstract: A method for managing a self-balancing vehicle includes establishing a first Blue Tooth connection with the self-balancing vehicle, acquiring traveling state data of the self-balancing vehicle through the first Blue Tooth connection, determining whether a smart warning mode is enabled, establishing a second Blue Tooth connection with a smart wearable device if the smart warning mode is enabled, acquiring a preset monitored item and a preset warning event, monitoring the monitored item in the traveling state data for determining whether the warning event has occurred, and sending a warning message to the smart wearable device through the second Blue Tooth connection if the warning event has occurred.

Abstract: This disclosure discloses an obstacle locating method and apparatus, which pertain to the field of locating technology. The obstacle locating method includes: acquiring a location of a locating device when an obstacle is found; adding the location and an identification of an indoor map corresponding to the location into location information; and sending the location information to a mobile device, where the location information triggers the mobile device to mark and display the location on an indoor map having the identification.

Abstract: A method for managing video data, includes: detecting whether an accident happens to a first vehicle; when it is detected that the accident happens to the first vehicle, sending to a server a first request for acquiring first video data, the first video data being driving record data of a second vehicle within a predetermined time period around happening of the accident, the second vehicle being a vehicle within a predetermined range around the first vehicle when the accident happens; and receiving the first video data returned from the server.

Abstract: Disclosed are a method, apparatus, and storage medium for alerting a cooking state of an electric cooker. The method includes: detecting a current cooking state of an electric cooker; generating cooking state alert information when a preset cooking state is detected; and sending the cooking state alert information to a target terminal for alerting a user to the current cooking state of the electric cooker.

Abstract: A method, device and medium for acquiring location information are provided. The method includes: acquiring a remaining power amount of a mobile terminal; acquiring location information of the mobile terminal when the remaining power amount of the mobile terminal is less than a preset threshold; and transmitting the location information to a target receiving terminal.

Abstract: A variable transmission includes driving and driven cone discs respectively having two movable and pressing cone discs; a pressing mechanism having an end surface cam pressing mechanism arranged on the back of one pressing cone disc of the driving and driven pressing cone discs; a ratio control mechanism having a ratio control shaft, hollow screws and nuts, arranged on the backs of the driving and driven movable cone discs and adopt ball screw structures or sliding screw structures; the ratio control shaft and a constant ratio transmission mechanism enable the conversion relationships between the rotation of the speed control shaft and the axial sliding of the driving and driven movable cone discs are be equal to each other to ensure the transmission shafts of the driving and driven movable cone discs move axially and synchronously at the same speed and in the same direction.
