Abstract

The invention provides a mobile communication device that combines the functions of cell phone (or mobile phone) and portable computer. The device has two separate main modules: a computer module and a handset that is wirelessly connected to each other. The computer module has all of the components of general purpose computer and in addition it has transmitter and receiver for establishing connection to a base station. Handset establishes connection to the telephone network using both wireless link to computer module and link between computer module and base station. It helps significantly decrease the power of harmful electromagnetic field that is radiated by all mobile phones, because in this case the main transmitter is on a distance from human head. Also it allows reducing size and weight of the handset. The handset also could be used to control computer module and any other electronic devices.

Description

MOBILE COMMUNICATION DEVICE WITH WIRELESS HANDSET

TECHNICAL FIELD This invention relates to a portable communication means and more spe- cifically to a communicator comprising phone and computer functionality.

BACKGROUND ART It is known to use a hand carried cellular or other type of phone. It is also known to use a portable pager with means for multiple pager messages and a pager display. Typical cellular phones and pagers are described in U.S. Pat. Nos. 5,884,188; 5,933,088; and 5,940,742. Also wearable hands-free computers are known. Hands-free computer is described in U.S. Pat. Nos. 5,304,244; and 5,844,824. Since phones, pagers and computers have been extensively used, it has become awkward to carry each on one person. In European Pat. No. 0,907,279 a mobile communicator is disclosed consisting of a wrist strap and an actual combined mobile communicator connected to it which has at least two separate mobile communicator parts. The parts of the mobile communicator are mechanically connected by joints so that they can be folded in against one another in repose position and can be opened profitably se- quential and parallel in usage position.

In U.S. Pat. No. 2002/0022499 a communication device is disclosed having a single unit called a personal communicator that combines the functions of a cell phone (or mobile phone), a body supported computer and a pager. The personal communicator has three detachable modules: a communication module, a display module and a core computer module. The core computer module has all of the components of a general purpose computer. Each of the modules when detached can be used in other systems such as with other screens.

In U.S. Pat. No. 6,085,112 a communication device is disclosed having a computer with speech input and output devices combined in one structure. Pref- erably, the computer can be removed from the device and communicate with the basic device using an infrared link. In addition, a broadband transmission link may be provided, radio waves which are independent of the telephone network making contact with computer servers which are preferably provided. While some of the above patents disclose mobile phones, two-way radios, pagers and computers, the disadvantage is that none of these patents suggest the use of carried mobile structure where the computer can be connected to the radio- network without using the phone.

It is due to the fact that transmitter and receiver modules for establishing a connection to the base station is situated inside phone module. Other disadvantages of this structure are harmful electromagnetic field that is radiated near the head of the user, comparatively big size of the phone module and non-ergonomic use of personal computer due to small size of display and keyboard that is restricted by the size of the phone. These disadvantages cause inconvenience in use of this device and harm to human health.

DISCOSURE OF INVENTION It is therefore an object of this invention to provide a mobile structure devoid of the above-noted disadvantages. Another object of this invention is to provide convenient use of this communication device.

Yet another object of this invention is to provide simultaneous use of computer and phone ftmctionality of this device.

Still a further object of this invention is to decrease the power of harmful electromagnetic field that is radiated near the head oh the user without reduction of the distance of well-provided connection between the device and a base station. Still another object of this invention is reducing the handset power consumption. Yet, still a further object of this invention is significant reducing the handset size.

These and other objects of this invention are accomplished by a communication device containing at least wireless handset and computer module, where both the handset and the computer module have transmitter and receiver to establish wireless connection to each other, and the computer module has additional transmitter and receiver for connecting to the base station. Due to the fact the power of handset transmitter can be significantly reduced that results in decreasing of power consumption, harmful radiation and size of the handset. Wireless connection between the handset and computer module allows performing some phone ftmctionality on the computer module and using data shared by both the handset and the computer module. For example it can be used for sharing of a database that stores phone numbers and addresses or sharing of sound records. The wireless connection also gives the opportunity to control the computer module remotely from the keypad of the handset.

Due to the fact that both the computer module and the handset have own keyboard and display they can have different embodiment. It gives the opportunity to satisfy user's requirements that are different for the computer and the phone. BRIEF DESCRIPTION OF DRAWINGS

FIG.l is a general view of the communication device of this invention where the handset, the computer module and wireless connections are shown;

FIG.2 is a functional layout of the wireless handset;

FIG.3 is a fractional layout of the computer module.

BEST MODE FOR CARRYING OUT THE INVENTION A general view of the communication device of this invention is illustrated on FIG.l. The communication device has at least one handset 1 and computer module 2, that interact with each other using wireless connection. The computer module is connected to base station 3 via another wireless connection. The handset is connected to a telephone network via both wireless connections through the computer module.

In FIG.2 functional layout of the wireless handset is illustrated. The handset has at least speech input and output devices unit 4, which is connected to signal processing unit 5, display unit 6, keypad 7, control unit 8, transmitter and receiver unit 9. Signal processing unit 5, display unit 6, keypad 7 are connected to the control unit 8. Control unit 8 is connected to transmitter and receiver unit 9.

In FIG.2 functional layout of the computer module is illustrated. The com- puter module has at least transmitter and receiver 10 for establishing wireless connection to the handset; display unit 11, keyboard 12; control unit 13, transmitter and receiver unit 14 to connect to a base station, central processing unit 15 and memory 16. In general the computer module can have all of the components of general purpose computer. The preferred and optimumly preferred embodiments of the present invention have been described herein and shown in the accompanying drawings to illustrate the underlying principles of the invention, but it is to be understood that numerous modifications and ramifications may be made without departing from the spirit and scope of this invention; for example wireless connection between the handset and the computer module can be established by radio transmission, ultrasonic or infrared link.

INDUSTRIAL APPLICABILITY Using up-to-date components for this device construction allows signifi- cantly decrease weight and size of the handset, reduce influence of harmful electromagnetic field and extend distance of well-provided connection to the base station due to increasing of the transmitter power that is situated in the computer module on a distance from the user. For example when using Bluetooth technology for wireless connection between the handset and the computer module the power of handset transmitter can be reduced to 1-2 mW, that is 1500-3000 times lower then the radiation power of typical GSM-900 cell phone.

The communication device of this invention can be used for telephone communications, receiving and transmitting of messages, images, files and facsimiles, performing calculations and data processing etc. Besides that, this communication device can be used as an audio player-recorder or as video telephone.
