Abstract

A receiver unit is added to a Personal Computer (PC) between the existing keyboard output and the PC keyboard input port. The receiver unit is responsive to a hand-held keypad transmitting infrared or ultrasonic signals which are passed to the PC. Also keystroke signals for the keyboard are transmitted via the unit to the PC. As the receiver unit is added by plugging in, no change is required to the PC itself or to its keyboard. A method is described to input a remote keypad to existing designs of the Personal Computer and main-frame terminals. By plugging the existing keyboard into the receiver unit and then the receiver unit into the keyboard socket, as shown in the figure, a very useful design has been implemented.

Remote Key Input to Personal Computer

A receiver unit is added to a Personal Computer (PC) between the existing keyboard output and the PC keyboard input port. The receiver unit is responsive to a hand-held keypad transmitting infrared or ultrasonic signals which are passed to the PC. Also keystroke signals for the keyboard are transmitted via the unit to the PC. As the receiver unit is added by plugging in, no change is required to the PC itself or to its keyboard. A method is described to input a remote keypad to existing designs of the Personal Computer and main-frame terminals. By plugging the existing keyboard into the receiver unit and then the receiver unit into the keyboard socket, as shown in the figure, a very useful design has been implemented. The receiver unit inputs to the system by signalling to the system keyboard interface as though it were the keyboard, and, by passing the signals from the keyboard to the system, it allows the existing keyboard to remain fully functional. The remote keypad transmitter is a small hand-held device which has only a subset of keyboard keys implemented. The full keyboard is still available to the user for the keys which are not implemented on the remote keypad. The transmitter is an infrared or ultrasonic transmitter keypad of the type used for controlling television or other domestic equipment. Each key on the keypad is identified with either a keyboard key or some function which can be invoked by a succession of ke...
