Abstract

A disposable wireless telephone and a method of using a disposable wireless telephone capable of use for telephonic communications only during a predetermined limited period, after which period the telephone is rendered inoperative and is discarded.

Claims

1. A disposable wireless telephone capable of use for telephonic communication by a user only during a predetermined limited period, after which period the telephone itself is rendered incapable of use and is discarded, the telephone comprising:

telephonic means within the telephone itself for transmitting and receiving telephonic communications;

enabling/disabling means within the telephone itself for enabling the telephonic means for telephonic communications during the predetermined limited period and rendering the telephone incapable of use upon expiration of the predetermined limited period;

the enabling/disabling means including setting means for setting the duration of the predetermined limited period prior to delivery of the telephone to the user;

selective operating means within the telephone itself for operating the telephonic means for telephonic communications of selected durations;

the enabling/disabling means including disabling means within the telephone itself and responsive to the selective operating means for rendering the telephone itself incapable of use when the sum of the selected durations reaches the predetermined limited period; and

tamper deterrent means within the telephone itself for precluding access to the setting means for any alteration of the duration of the predetermined limited period once the setting means has been set so as to preclude any resetting of the predetermined limited period subsequent to delivery of the telephone to the user such that the telephone itself is rendered incapable of use beyond the predetermined limited period and is capable of being discarded.

2. The invention of claim 1 wherein the setting means includes a source of power of given capacity.

3. The invention of claim 1 wherein the setting means includes a timing mechanism.

4. The invention of claim 1 including a case and the tamper deterrent means includes a matrix material within the case, the telephonic means and the enabling/disabling means being embedded in the matrix material so as to deter tampering.

5. The invention of claim 4 wherein the matrix is constructed of a synthetic polymeric material.

6. The invention of claim 1 including a case having a relatively thin case wall formed of a synthetic polymeric material.

7. The invention of claim 6 wherein the case has an outer configuration and the relatively thin case wall is vacuum formed into the outer configuration.

8. The invention of claim 6 wherein the tamper deterrent means includes a matrix in the case, with the matrix mechanically reinforcing the thin case wall.

9. The invention of claim 8 wherein the telephonic means and the enabling/disabling means are embedded in the matrix so as to deter tampering.

10. A method of using a disposable wireless telephone for telephonic communications during only the duration of a predetermined limited period, after which period the telephone itself is rendered incapable of use and is discarded, the telephone including telephonic means for transmitting and receiving telephonic communications, the method comprising:

setting the duration of the predetermined limited period prior to delivery of the telephone to a user;

enabling the telephonic means itself for telephonic communications during the duration of the predetermined limited period;

operating the telephonic means for telephonic communications of selected durations;

rendering the telephone incapable of use upon the sum of the selected durations reaching the duration of the predetermined limited period; and

precluding any alteration of the duration of the predetermined limited period, once the duration of the predetermined limited period is set, subsequent to delivery of the telephone to the user such that the telephone itself is rendered incapable of use beyond the predetermined limited period and is capable of being discarded.

11. The invention of claim 10 wherein:

setting the duration of the predetermined limited period is accomplished with setting means placed within the telephone itself; and

alteration of the duration of the predetermined limited period is precluded, once the duration of the predetermined limited period is set, by precluding access to the setting means for resetting subsequent to delivery of the telephone to the user.

12. The invention of claim 11 including:

summing the selected durations; and

comparing the sum of the selected durations to the set duration of the predetermined limited period.

13. The invention of claim 10 including discarding the telephone upon expiration of the predetermined limited period.
