ABSTRACT:
A protective device 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 device 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.
