Abstract

A laptop device, battery powered, wireless control station transmits encrypted device signals to a receiver interfaced with a host desktop computer. The laptop device includes a microprocessor which converts Input/Output device signals into a secured code and transmits the secured code to a computer interface transceiver using the same frequency. The laptop device receives and sends signals to the keyboard, monitor, joystick, mouse, speakers and microphone. The computer interface transceiver called the Base Unit only recognizes or accepts secured signals with authenticated encryption passwords. For the signals accepted the Base Unit forwards the signals to the host computer via a physical connection to the appropriate device. The Base Unit also transmits the secured signal codes back to the laptop device called UIU (User Interface Unit) which then allocates the signal to the appropriate device located on the UIU. In addition, all messages that originate in the computer will be transmitted to the UIU and displayed on the display therein in a secure manner.

Claims

1. A wireless laptop computer controller system for a host desktop computer, comprising:

A laptop terminal including;

A keyboard for entering key strokes;

A high resolution monitor;

A mouse touch pad;

A joystick port;

Small amount of memory to hold a security code;

a computer end transceiver including;

wireless transmit/receive means for wirelessly receiving the device signals and the security code, and always transmitting;

device signals means for each connection going to the desktop from the devices listed in claim 1 will be converted to corresponding signals.

2. A system as recited in claim 1, wherein when the User Interface Unit (UIU) transmit/receive encrypted signals to the Base Unit. The signal is decoded with the security code, which is used as a key.

3. A system as recited in claim 2, where in the transmission of the signal comes directly from the device recited in claim 1.

4. A device (UIU) as recited in claim 2, where in the device has several connections to the corresponding desktop devices recited in claim 1.
