An advanced wire/wireless keyboard for use in a computer system, which comprises a user ID (identification) setting function. When the keyboard operates with wireless communication, the keyboard controller allows delivery of the user ID information, to which an keyboard data signal is added, to the computer main unit,With this keyboard, the noise generation is prevented by generating a specific wireless signal corresponding to the user ID information. The keyboard has a rechargeable battery and a battery charging circuit for charging the rechargeable battery during wire communication for subsequent use during wireless communication.

Wire/wireless keyboard for use in a computer system and a method of operating the same

A method and device for controlling a CPU stop clock interrupt of a computer system. The device includes an idle detector and a control processor. A CPU having a stop clock interrupt mode receives a stop clock interrupt signal and sets up and clears the stop clock interrupt mode according to a logic state of the stop clock interrupt signal. The control processor receives a signal representing an idle condition of the computer system from the idle detector, a signal for enabling idle detector control of the CPU stop clock interrupt mode and a signal for forcing the CPU to resume a normal mode by clearing the stop clock interrupt mode. The idle condition can be defined by a computer user according to a selection of predetermined times during which no user inputs are received by the computer system. The method includes monitoring the idle condition of the computer system, monitoring the signal for enabling idle detector control of the stop clock interrupt mode and monitoring the signal for forcing the CPU to resume a normal mode by clearing the stop clock interrupt mode. The stop clock interrupt signal is output having a logic state corresponding to the logic combination of the monitored signals.

Method and device for controlling a CPU stop clock interrupt

A method and device for controlling a CPU stop clock interrupt of a computer system. The device includes an idle detector and a control processor. A CPU having a stop clock interrupt mode receives a stop clock interrupt signal and initiates and terminates the stop clock interrupt mode according to a logic state of the stop clock interrupt signal. The control processor receives a signal representing an idle condition of the computer system from the idle detector, an alternate signal for idle detector control of the CPU stop clock interrupt mode, and a control signal for forcing the CPU to resume a normal mode by clearing the stop clock interrupt mode. The idle condition can be defined by a computer user according to a selection of predetermined times during which no user inputs are received by the computer system. The method includes monitoring the idle condition signal, monitoring the alternate signal for idle detector control of the stop clock interrupt mode and monitoring the control signal for forcing the CPU to resume a normal mode by clearing the stop clock interrupt mode. The stop clock interrupt signal is output having a logic state corresponding to the logic combination of the monitored signals.

System for controlling stop clock interrupt mode according to user

A peripheral device input-initiated resume system for a combined hibernation system and back-up power supply for a computer comprises a keyboard controller for inputting an appropriate signal to the operating condition based on the key selected by a user, a power management system for outputting a wake-up signal if the signal is inputted from the keyboard or other input devices, a data back-up power unit for supplying DC voltage in case the power is cut-off suddenly or a user does not use the computer for a predetermined time, a power supplying unit in which a switching-mode power supply SMPS converts the external source AC power at line voltage into DC power at a desired voltage and supplies that power to each device on the main board of the computer, thereby retrieving the previous work again by cutting off power of all devices, once the power is off or when a user does not use the computer for a predetermined time, and supplying the additional power only to the MICOM(Micro Computer) or keyboard controller in the state that a hibernation mode is performed. Then the system repeats supplying power if a signal is input again by a user, and consequently helps a user to use the computer more easily with this hibernation state by retrieving the work to the previous state.
