Abstract

A protective method for storage and transport containers comprises a sensor for detecting orientation, an attachment element for securing the sensor to a container, and an alarm operatively coupled to the sensor for generating a cognizable alert signal upon detection by the sensor that the container is in an orientation other than a predetermined preferred orientation. The alarm may include an electroacoustic transducer and means for reproducing a voice message. A timer operatively connected to the sensor measures a time interval during which the container is in an orientation other than the preferred orientation. A memory is operatively connected to the timer for automatically storing the time interval in encoded form. A mechanism and/or circuit may be operatively connected to the timer and the memory for deactivating the timer and for locking the memory to ensure integrity of contents of the memory upon an opening of the container. The method may also include a detector for measuring temperature. The alarm is operatively connected to the detector for generating a cognizable indicator signal upon measurement of a temperature beyond a pre-established threshold. The timer is operatively connected to the temperature detector for measuring a time period during which the container is in a temperature range beyond the threshold, while the memory is operatively connected to the timer for automatically storing the time period in encoded form.

Claims

1. A protective device for storage and transport containers, comprising:

sensing means for detecting a physical condition of a predetermined kind;

attachment means for securing said sensing means to a container;

a timer operatively connected to said sensing means for determining that the detected physical condition has continued longer than a preselected duration, said timer further including a timing means operatively connected to said sensing means for measuring a time interval indicating the duration of the detected physical condition;

a memory means operatively connected to said timing means for automatically storing said time interval in encoded form; and

a wireless telecommunications transmitter operatively connected to said timer for establishing a wireless telecommunications link to a predetermined remote receiver and transmitting, over said link to said receiver, a message that said detected physical condition has existed longer than said predetermined duration.

2. The device defined in claim 1 wherein said physical condition is orientation, said sensing means including components for detecting that the container is in an orientation other than a predetermined preferred orientation.

3. The device defined in claim 2, wherein said timing means is operatively connected to said sensing means such that said time interval measures a duration in which the container is in an orientation other than said preferred orientation.

4. The device defined in claim 3, further comprising means operatively connected to said timing means and said memory means for deactivating said timing means and for locking said memory means to ensure integrity of contents of said memory means upon an opening of the container.

5. The device defined in claim 1 wherein said physical condition is temperature, said sensing means including means for detecting that the container has a temperature beyond a predetermined threshold.

6. The device defined in claim 5, wherein said timing means is operatively connected to said sensing means such that said time period measures a duration in which the container is in a temperature range beyond said threshold.

7. A method for use in protecting contents of storage and transport containers, comprising:

automatically and at least periodically monitoring a storage and transport container with fragile contents to detect whether the container has a pre-established physical condition;

in the event that the container has the pre-established physical condition, automatically determining whether the container has had the pre-established physical condition for a time interval longer than a preselected duration automatically measuring a time interval during which the pre-established physical condition is determined and automatically storing said time interval in encoded form in a memory;

upon determining that the container has had the pre-established physical condition for a time interval longer than said preselected duration, establishing a wireless telecommunications link to a predetermined remote receiver; and

upon the establishing of said link, transmitting, over said link to said receiver, a message that the container has had the pre-established physical condition for a time interval longer than said preselected duration.

8. The method defined in claim 7 wherein said physical condition is an orientation other than a predetermined preferred orientation, the monitoring of said container including detecting that the container is in an orientation other than said preferred orientation.

9. The method defined in claim 8, wherein said step of automatically measuring said time interval comprises automatically measuring a time interval during which the container is in an orientation other than said preferred orientation.

10. The method defined in claim 9, further comprising locking said memory to ensure integrity of contents of said memory upon an opening of the container.

11. The method defined in claim 7 wherein said physical condition is a temperature beyond a predetermined threshold, the monitoring of said container including detecting that the container has a temperature in a range beyond said predetermined threshold.

12. The method defined in claim 11, wherein said step of automatically measuring said time interval comprises automatically measuring a time interval during which the container is in a temperature range beyond said threshold.

13. The method defined in claim 7, further comprising automatically generating an alarm signal cognizable within a region about said container, upon detecting that the container has said pre-established physical condition.

14. The method defined in claim 13 wherein the generating of said alarm signal includes producing a sound wave via an electroacoustic transducer.

15. The method defined in claim 14 wherein the producing of said sound wave includes producing a voice message.
