Abstract

Rotatable easels position cellular telephones away from users'"'"' heads. Earpieces and microphones are on a shielded surface. Control keys and communications screens face away from a user. Back-to-back screens on opposite sides increase space for visual information and messages. Biodegradable, conductive shielded covers and cases and printed antennas protect users. Rubber grips and depressed conductive keys protect the equipment.

Claims

1. Telephone apparatus comprising:

a hand held case made of biodegradable conductive plastic;

an antenna mounted on the case;

electronics mounted within the case;

control keys mounted on one surface of the case for controlling the electronics within the case;

a speaker mounted on the case and a microphone mounted on the case for respectively converting electronic signals to sounds and vice versa; and

a spacer easel movably connected to the case for lying adjacent the case when the electronics are not in use, and for deploying to a human body member spacing position when the electronics are in use for spacing the speaker and sources of radiation related to the electronics and the antenna away from the human body member during use, the easel rotating about 270°

around a hinge on a top of the cellular telephone for a closed position along one side of the cellular telephone to an open position about 90°

from an opposite side of the phone when the cellular telephone is in use for talking and listening by a user.

2. The apparatus of claim 1, wherein the antenna further comprises a printed antenna mounted on the case at a position away from the speaker and the microphone.

3. The apparatus of claim 1, wherein the case is made of a conductive plastic material.

4. The apparatus of claim 1, wherein the case is made of a biodegradable conductive plastic material.

5. The apparatus of claim 1, wherein the control keys are recessed in a face of the case.

6. The apparatus of claim 1, further comprising conductive plastic shielding material panels connected to the case.

7. The apparatus of claim 6, wherein the shielding panels have openings adjacent speakers and microphones.

8. The apparatus of claim 6, wherein the shielding panels have openings for receiving the control keys.

9. The apparatus of claim 1, further comprising elastomeric grips mounted on side or top and bottom surface of the case for holding the case and protecting the case and its contents.

10. Telephone apparatus comprising:

a hand held case made of biodegradable conductive plastic;

an antenna mounted on the case;

electronics mounted within the case;

control keys mounted on one surface of the case for controlling the electronics within the case;

a speaker mounted on the case and a microphone mounted on the case for respectively converting electronic signals to sounds and vice versa;

a spacer easel movably connected to the case for lying adjacent the case when the electronics are not in use, and for deploying to a human body member spacing position when the electronics are in use for spacing sources of radiation related to the electronics and the antenna away from the human body member during use,

wherein the human body member is a human head; and

wherein the spacer easel is hinged at a hinged end to the case and extends at an acute angle nearly perpendicularly from the case in the deployed, spacing position and has a free edge opposite the hinged edge for lying against the human head and for spacing the electronics and the antenna away from the head while the electronics are in use, the spacer easel rotating about 270°

around a hinge on a top of the cellular telephone for a closed position along one side of the cellular telephone to an open position about 90°

from an opposite side of the phone when the cellular telephone is in use for talking and listening by a user.

11. The apparatus of claim 10, wherein the spacer easel is hinged at a top of the case.

12. The apparatus of claim 10, wherein the spacer easel is hinged at a bottom of the case.

13. The apparatus of claim 10, wherein the spacer easel is hinged at a side of the case.

14. The apparatus of claim 10, wherein the spacer easel is hinged at a back of the case.

15. The apparatus of claim 14, wherein the speaker and the microphone are mounted on the back of the case;

and

wherein the control keys are mounted on a front of the case for facing away from the human head when the electronics are in use.

16. The apparatus of claim 15, further comprising a display screen mounted on the back of the case for displaying information to the user.

17. The apparatus of claim 16, further comprising a smaller conventional data display mounted on the front of the case near the control keys.

18. Telephone apparatus comprising:

a hand held case made of biodegradable conductive plastic;

an antenna mounted on the case;

electronics mounted within the case;

control keys mounted on one surface of the case for controlling the electronics within the case;

a speaker mounted on the case and a microphone mounted on the case for respectively converting electronic signals to sounds and vice versa;

conductive plastic shielding material on surfaces of the case for protecting users and the electronics from radiation;

a spacer easel rotating about 270°

around a hinge on a top of the cellular telephone for a closed position along one side of the cellular telephone to an open position about 90°

from an opposite side of the phone when the cellular telephone is in use for talking and listening by a user.

19. The apparatus of claim 18, further comprising elastomeric grips mounted on side or top and bottom surface of the case for holding the case and protecting the case and its contents.

20. Telephone apparatus comprising:

a hand held case made of biodegradable conductive plastic;

an antenna mounted on the case;

electronics mounted within the case;

control keys mounted on one surface of the case for controlling the electronics within the case;

a speaker mounted on the case and a microphone mounted on the case for respectively converting electronic signals to sounds and vice versa;

wherein the case has front and rear opposite faces, a display on the front face of the case near the control keys, and a second display on the rear face;

a spacer easel rotating about 270°

around a hinge on a top of the cellular telephone for a closed position along one side of the cellular telephone to an open position about 90°

from an opposite side of the phone when the cellular telephone is in use for talking and listening by a user.
