Abstract: Embodiments of the present invention disclose a human-machine interaction method and apparatus. The method includes: capturing a line-of-sight direction; determining a change of an angle between a line of sight and a screen, and/or a change of a distance between a user and the screen according to the line-of-sight direction; and performing, according to the change of the angle and/or the change of the distance, a corresponding operation on content displayed on the screen. Corresponding to the foregoing method, the foregoing apparatus includes: a line-of-sight tracking unit, a processing unit, and an executing unit. In the present invention, an action of a user can be determined without depending on gravity sensing, and a corresponding operation can be performed on content displayed on a screen.

Abstract: The present invention discloses a control apparatus applied to a digital power supply device, and a digital power supply device, and pertains to the digital power field. The control apparatus includes: an operational amplifier, an analog to digital converter, a feedback digital filter, a digital pulse-width modulator, a power-level circuit, a feedforward digital filter, and a feedback network. A feedforward function is achieved by configuring a feedforward digital filter, which reduces the number of tables that are used to implement a reciprocal curve, and avoids problems of a long operational delay, a huge resource waste, and a poor feedforward effect.

Abstract: A foldable apparatus is provided. The foldable apparatus includes a first foldable part, a middle bending part, and a second foldable part that are connected in sequence. The first foldable part and the second foldable part can rotate relative to each other based on the middle bending part. A first wireless communication chip is disposed in the first foldable part. A second wireless communication chip is disposed in the second foldable part. In the foldable apparatus, wireless communication is used to replace conventional physical wiring for internal signal transmission. The loss of a communication carrier is reduced through wireless communication. This ensures that stable transmission performance between the first foldable part and the second foldable part.
