Abstract: Disclosed in the present disclosure is a vehicle-mounted table plate fixed to a steering wheel. The vehicle-mounted table plate fixed to a steering wheel includes a base plate; a base, where the base plate is rotationally connected or fixedly connected at one end of the base; and at least two clamping arms having the same structure or different structures, where the clamping arms are connected at a front end of the base in a back-and-forth stretchable manner, each clamping arm includes a clamping hook rotationally connected to a front end of the clamping arm, and the clamping hooks are used for being clamped on the steering wheel of a vehicle. Clamping gaps between the clamping hooks and the base are adjusted by moving the clamping arms back and forth to achieve mounting and fixing of the table plate fixed to a steering wheel.

Abstract: Provided is a method for controlling a wearable device. The method includes acquiring a first time stamp, where the first time stamp is a time at which a user starts climbing; calculating a single-lap climbing altitude of the user according to data of a barometer; acquiring a second time stamp according to a preset single-lap altitude and the single-lap climbing altitude; calculating a climbing time according to the first time stamp and the second time stamp; and calculating a single-lap vertical velocity according to the climbing time and the single-lap altitude.

Abstract: A vehicle-mounted foldable storage box includes a storage box body which is sequentially provided with a left box body and a right box body. Elastic buckles are arranged on two opposite sides of the surface of the left box body. A clamping table is arranged at one end of the bottom of the elastic buckle. A sliding rail is arranged on the bottom surface of the left box body. A plurality of groups of teeth are transversely arranged on one side of the sliding rail.

Abstract: Disclosed are ways to generate a melody. Currently, no algorithm exists for automatically composing a melody based on music lyrics. However, according to some recent studies, within a song, there usually exists a correlation between a song's notes and a song's lyrics wherein a melody can be generated based on such correlation. Disclosed herein, are systems, methods and algorithms that consider the correlation between a song's lyrics and a song's notes to compose a melody.
