Abstract

A small light weight modular microcomputer based computer and communications systems, designed for both portability and desktop uses. The systems make use of a relative large flat panel display device assembly (2), an expandable hinge device (10), battery power source (9), keyboard assembly (16), and wireless communications devices (32, 51). The systems are capable of bi-directional realtime communications of voice, audio, text, graphics and video data. Both wire-based or wireless communications methods and devices are implemented. Wireless communications devices may include one or more telephone-like handsets (14) and/or earset (34). The wireless communication devices may include one or more antennae (32). Systems can be configured in a portable arrangement similar to conventional notebook computers, but can be quickly and easily disassembled and re-assembled for office desktop uses. Systems may consist of a base computer unit (100) comprising wireless communication devices may act as a relay station relaying voice and other data between the handset or earset and external wide area communications networks. The system may be capable of performing, personal digital assistant (PDA), cellular telephone, conventional notebook computer, desktop computer functions.

Claims

1. A portable wireless communication system including a microcomputer system to be operated by a user for voice and data communications to and from external wide area communications networks and for data processing, the wireless communications systems comprising of:

a) a notebook computer adapted to function as a base unit for digital wireless communications, comprised of a microprocessor, transceiver and flat panel display, wherein the electrical power of the notebook computer is sufficient to communicate with external wide area communications networks;

b) a handset for digital wireless communications having a structure, shape, and function set substantially different than said notebook computer, wherein said handset is adapted to communicate with the notebook computer, via electromagnetic radiation means, and wherein electrical power of the handset unit is substantially less than the power the notebook computer notebook computer; and

c) said notebook computer performing a communications in a bi-directional manner, relaying digital data between the handset and the wide area network, wherein the lower power handset is normally placed next to the user'"'"'s ear during voice communications, but the user has the option to place the higher power notebook computer several feet away from the user such as in the same or nearby room.

2. A portable wireless communication system of claim 1, in which the means for handset communications is replaced by means for earset communications for lighter weight and hand free operations by the user.

3. A portable wireless communication systems of claim 1, in which the user has the option to switch the electrical power level of the handset means to either high power levels for communication directly with the wide area communications network, or switch to lower power levels for communications to the notebook computer.

4. A method for notebook computing and wireless communicating of voice and data to and from external wide area wireless communications networks, the method comprising the steps of:

a) transmitting digital data to at least one external wide area wireless communications network from a notebook computer, via electromagnetic radiation means, wherein the electrical power of said notebook computer is sufficient to communicate with wide area wireless communications networks;

b) receiving digital data from a wide area wireless communications network to said notebook computer, via electromagnetic radiation means, wherein the electrical power is sufficient to communicate with wide area wireless communications networks;

c) transmitting digital data to a handset unit from said notebook computer via electromagnetic radiation means, wherein the structure and functions set of said handset are different than said notebook computer, and the power of the handset unit is substantially less than the power of said notebook computer;

d) receiving digital data from the handset unit to said notebook computer via electromagnetic radiation means, wherein power of the handset unit is substantially less than the power of said notebook computer; and

e) said notebook computer performs bi-directional relay communication functions between the handset unit and wide area wireless communications networks, and performs conventional data processing via a microprocessor system, wherein data is displayed on a large display screen of said notebook.

5. A method for portable computing and wireless communicating of claim 4, in which the user has the option to execute a plurality of application programs on the microcomputer means, typically including telephony programs, personal productivity programs, e-mail programs, voice mail programs, Internet programs and other conventional PC programs.

6. A method for portable computing and wireless communicating of claim 5, in which execution of the application programs, voice communications operations and data communications operations are performed on time shared basis, so that the user has the option to perform a plurality of communication and computing tasks, roughly simultaneously.

7. A notebook computer having wireless communication functions for use by an individual for voice and digital data communications, the notebook computer comprising:

a. a first half panel structure having a flat panel display device and control electronics;

b. a second half panel structure physically connected to the first half panel structure via a hinge means,

c. a microprocessor electrically interfaced to the flat panel display device;

d. a wireless digital data and voice communication means electrically interfaced to the microprocessor, wherein the communication means comprises one or more microphones, audio speakers, and antenna means; and

e. said first and second panel structures can be closed together in a clam shell manner, wherein the notebook computer is operational providing voice communication functions even while the two halves are in a closed position.

8. A notebook computer as recited in claim 7, further comprising a full size keyboard located in the second half panel structure and electrically interfaced to the microprocessor.

9. A notebook computer as recited in claim 7, further comprising an attached battery module adapted to quick connection and dis-connection to one of the half panel structures, such that the battery module can be easily and quickly swapped with another battery module.
