[Prior art]

 An appropriate transmission interface is provided between the well-known computer and its peripheral equipment, and the signal conversion operation and data transmission are achieved by being interconnected by a signal cable. However, since the signal cables are located between each peripheral device and the computer, it is impossible to prevent each peripheral device from being affected by conductors, for example, the movement range of the mouse is limited, and tablets and keyboards are not It could not be installed over the length of the conductor, which caused inconvenience and problems in operation.

The new era of wireless computer peripherals provides an effective solution to this problem, so that various peripherals are not restricted by connecting cables, and for computers, By simply adding a single USB wireless signal receiver and connecting it to the USB communication interface of the computer with a cable, this computer can control various wireless peripheral devices such as a keyboard, mouse, joystick, tablet, game board, etc. Signals can be received, and the object of enabling each USB peripheral equipment to operate and control a computer in a wireless manner is achieved.

However, USB wireless signal receivers also have one obvious disadvantage. That is, an extra and independent power source is required, for example, the working power must be provided by a DC battery. The power consumption of this wireless signal receiver is not very large, but the amount of power of the DC battery is finite and has a fixed service life, so if the wireless signal receiver is used for a certain period, the battery needs to be replaced. In particular, when the wireless signal receiver is not used for a while, that is, when the operator is not using the computer, and the battery power is still continuously consumed, the service life of the battery is shortened and energy is wasted.
