A USB-based wireless transmitting/receiving system includes a transmitting portion connected to at least one USB-based peripheral device for receiving a signal from the peripheral device and a receiving portion connected to a computer host and coupled to the transmitting portion in a wireless fashion for receiving and applying the signal from the transmitting portion to the computer host whereby a wireless communication is established between the computer host and the USB-based peripheral device. Both the transmitting portion and the receiving portion include a central processing unit for processing signals received, a receiving unit for receiving signals, a transmitting unit for transmitting signals and a power supply system for powering the transmitting portion or the receiving portion. The power supply system includes a regulation circuit adapted to connect to an electric main. The power supply system may selectively include a primary battery set, a secondary battery set and/or a solar cell system, all connected to a controller to which the regulation circuit is also connected for selectively powering the transmitting portion or the receiving portion.

A charging system is incorporated in a computer communicable through a predetermined communication channel with a wireless peripheral device having a predetermined identification code. The charging system includes a charging device mounted to and in electrical connection with the computer. The charging device has a positive terminal, a negative terminal and a reset terminal. A rechargeable device is mounted in the wireless peripheral device. The rechargeable device includes a positive terminal, a negative terminal and a reset terminal corresponding to and engageable with the terminals of the charging device. The wireless peripheral device is selectively attached to the computer with the terminals engage each other to conduct an electrical current from the computer to the rechargeable device of the peripheral device and to reset/identify the communication channel and the identification code.

A digital rotary switch signal reading circuit is adapted to read volume control signal from a volume control knob mounted on a multi-medium keyboard. The rotary switch has two signal terminals and one common terminal. The signal terminals are connected to two of input pins of a microprocessor of the keyboard and the common terminal is connected to one of the output pins of the microprocessor, the input pins and the output pins being interconnected with each other to form a key array. Thus, the signal from the rotary switch may be read by the computer in the same way as key actuation signal from the key array.
