Abstract: Disclosed are a method and apparatus for sleep monitoring, an electronic device and a computer readable medium, relating to the field of health monitoring technology, the method comprises: a screen state of a target terminal is obtained; physiological parameters of a user are obtained, the physiological parameters including at least one of body motion parameters and heart rate parameters; a sleep state of the user is determined based on the screen state and the physiological parameters. Since the screen state can reflect the user's operation of the user terminal, and the operation can further reflect the sleep state of the user, and the physiological parameters can also reflect the sleep state of the user, the combination of the screen state and the physiological parameters can make the determination of sleep state more accurate.

Abstract: A current collecting board includes a base board, a conductive board mounted on the base board, a number of conductive plates, and a number of security elements. The base board includes a first surface, a second surface, and a number of receiving protrusions extending upwardly from the first surface. The base board defines a number of first through holes, each receiving protrusion surrounds a first through hole. Each conductive plate defines a second through hole. The receiving protrusion includes a number of leading blocks and a number of clamping blocks; each conductive plate is received in a receiving protrusion and clamped between the leading blocks and the clamping blocks. One end of each security element is solder to and electrically connected to a conductive plate, the other end of each security element is soldered to the conductive board. A battery module using the current collecting board is also provided.
