Abstract: A multimedia computer keyboard is provided having one or more high fidelity, diaphragm-type speakers mounted within the keyboard. Mono or stereophonic wiring to each speaker is achieved using existing keyboard cable extending from the keyboard to a keyboard connector arranged upon a host computer. A terminal at the end of the keyboard cable can plug directly into the keyboard connector, such that the terminal can receive an audio output signal generated from a sound card placed within the computer. Accordingly, audio output can be sent to the computer keyboard as an integrated system in order to achieve multimedia function.

Abstract: A power management control unit and system is provided for selectively controlling ac power to one or more computer peripheral devices. The power management control unit includes a power cord connected to an ac supply and an outlet pin capable of electrically receiving the peripheral device. The management control unit also includes an ac switch electrically coupled between the power cord and the outlet pin, such that the switch can modulate conduction between the power cord and the outlet pin during use. The power management control unit is maintained separate from existing computers and peripherals such that computers and peripheral devices need not be retrofitted or adapted with the control unit. The control unit takes advantage of video control signals available at the computer video output in order to turn off or on ac power to the outlet pin.
