Abstract

A portable telephone, which is used for emergency purposes. It is powered by a battery, which has a short life counterbalanced by higher power, thus improving efficiency and effectiveness of the emergency portable telephone. The battery may be sealed in a container for prolonging the life of the battery during the period of time that the telephone is inactive. In an emergency situation, the container may be pierced, and the battery freed to perform its duty.

Claims

1. An emergency portable telephone, comprising:

a transceiver;

a switch having an on-position and an off-position, the switch is connected to the transceiver in a manner which activates the transceiver when the switch is in the on-position and deactivates the transceiver when the switch is in the off-position, the normal status of the switch being in the off position, resulting in preventing the telephone from receiving phone calls;

a battery connected with the transceiver through said switch, the battery supplies power to the transceiver when the switch is in the on position, the life of the battery being limited to last for a predetermined duration of emergency phone calls made within a predetermined period of time, after the switch has been turned to the on-position; and

a timer activated by a first occurence of the switch being set in the on-position for interrupting power supplied to the transceiver at the conclusion of said predetermined period of time;

wherein subsequent openings or closings of the switch has no influence on interrupting the activated timer.

2. The portable telephone of claim 1, further comprising a box, in which the battery is enclosed in a sealed form in order to be protected from the atmosphere, so that the useful life of the battery is considerably prolonged for as long as the telephone is inactive.

3. The portable telephone of claim 2, further comprising means for piercing the box.

4. The portable telephone of claim 1, wherein the telephone further comprises a closure containing the switch, which closure has to be withdrawn before the switch becomes operable.

5. The portable telephone of claim 1, wherein the life of the battery is between 3 and 10 minutes.

6. The portable telephone of claim 5, wherein the life of the battery is between 4 and 7 minutes.

7. The portable telephone of claim 5, wherein the power given by the battery is not less than 2 watts.

8. The portable telephone of claim 1, further comprising a box, in which the battery is enclosed in a sealed form in order to be protected from the atmosphere, so that the useful life of the battery is considerably prolonged for as long as the telephone is inactive.

9. The portable telephone of claim 8, further comprising means for piercing the box.

10. The portable telephone of claim 9, wherein the means for piercing the box are part of the switch.

11. An emergency portable telephone, comprising:

a switch having an on-position and an off-position, the switch is connected to the transceiver in a manner activates the transceiver when the switch is in the on-position and deactivates the transceiver when the switch is in the off-position, the normal status of the switch being in the off position, resulting in preventing the telephone from receiving phone calls;

a box;

a battery disposed in the box in a sealed form from the atmosphere; and

piercing means for piercing the box and establishing contact between the switch and the battery, so that when the switch is turned on, the battery powers the transceiver;

the piercing means being part of the switch.

12. The portable telephone of claim 11, wherein the telephone further comprises a closure containing the switch, which closure has to be withdrawn before the switch becomes operable.

13. An emergency portable telephone, comprising:

a transceiver,

a switch having an on-position and an off-position, the switch is connected to the transceiver in a manner activates the transceiver when the switch is in the on-position and deactivates the transceiver when the first switch is in the off-position, the normal status of the switch being in the off position, resulting in preventing the telephone from receiving phone calls;

a battery connected with the transceiver through said switch, the battery supplies power to the transceiver when the switch is in the on position, the life of the battery being limited to last for a predetermined duration of emergency phone calls made within a predetermined period of time, after the switch has been turned to the on-position;

a timer activated by the switch for interrupting power supplied from the battery to the transceiver at said predetermined period of time;

a box, in which the battery is enclosed in a sealed form in order to be protected from the atmosphere, so that the useful life of the battery is considerably prolonged for as long as the telephone is inactive; and

means for piercing the box and establishing electrical contact between the battery and the switch, the piercing means being part of the switch.

14. An emergency portable telephone as defined in claim 13, wherein the timer interrupts the electrical continuity of the battery with the transceiver after the predetermined period of time, even when the switch is in the on-position.
