Abstract: The invention discloses a convenient human and animal power drive permanent magnet power generation and storage system, comprising a grip power drive power generation system; the grip power drive power generation system is a dumbbell-shaped grip power generation device, comprising a grip handle and power generation devices provided at both ends of the grip handle; the power generation device is composed of a permanent magnet generator, a tensioning wheel, a spring sheet, a winder ratchet device, and a battery; folding buckles are provided between the power generation devices at both ends and the grip handle so as to be folded inward. The invention solves the problem of continuous power guarantee of wearable intelligent device; in the invention, the grip-type slow gear is designed as a spring tensioning device similar to a mechanical watch; the stress generated during the grip tightens the spring.

Abstract: Method and apparatus for configuring channel characteristics of a reference signal, and a communication device are described. The method includes determining first type signaling, where the first type signaling carries a first type set and the first set includes a plurality of index elements; and sending the first type signaling to a second communication node.
