Remote monitoring of the munition assets is directed to providing a munitions monitoring system and method for monitoring the environment approximate to a munition and transferring data of the environment to a location remote from the munition for storage or processing. A local monitoring device communicates directly with a remote device at a location remote from the munition, the monitoring device being proximate to a munition with a plurality of sensors that monitor the environment of the munition. The local monitoring device can communicate directly with a centralized relay system that is located in the general proximity to a munitions stock pile and/or with a mobile remote device, such as mounted on a vehicle or a hand-held device. The data can be correlated with the operability of the munition.

Remote monitoring of munition assets

A piezoelectric actuator and a method of assembling and employing a piezoelectric actuator. This method comprises the steps of positioning an expandable piezoelectric material inside a case, and enclosing a vaporizable liquid in the case. The case is positioned in a high temperature environment; and the liquid vaporizes, in that high temperature environment, over a given period of time, to maintain the temperature of the piezoelectric material below a given value for said period of time. Preferably, the vaporizing liquid maintains the temperature of the piezoelectric material substantially constant over that period of time. Also, preferably the case is provided with a pressure responsive valve that opens and closes, in the high temperature environment, to expose the liquid to that environment and control the vaporization of the liquid to maintain the temperature of the piezoelectric material substantially constant over the period of time.
