Patent ID: 8677802

Claim:
A sensing module for monitoring at least one external environmental input, the sensing module comprising: a housing; at least one energy storage device within the housing; at least one set of electromechanical sensing elements within the housing, the electromechanical sensing elements being individually responsive to an external environmental input, each of the electromechanical sensing elements defining an open electrical path when not subjected to the external environmental input and operable to define a closed electrical path that produces an output in response to the external environmental input only while the electromechanical sensing element is subject to the external environmental input, only if the external environmental input is at a level that exceeds a threshold of the electromechanical sensing element, and only for a duration during which the level of the external environmental input exceeds the threshold of the electromechanical sensing element, then again defining the open electrical path thereof so as not to produce the output when no longer subject to the level of the external environmental input that exceeded the threshold thereof, the output of each of the electromechanical sensing elements indicating the threshold of the external environmental input that produced the output and corresponding to the duration that the level of the external environmental input exceeded the threshold thereof; means within the housing for generating data corresponding to the outputs of the electromechanical sensing elements, the data comprising an amplitude of the external environmental input and the durations that the level of the external environmental input exceeded the thresholds of the electromechanical sensing elements; and means within the housing for recording the data; wherein the electromechanical sensing elements, the generating means, and the recording means are powered only by the energy storage device when, respectively, producing the output, generating the data, and recording the data in response to the external environmental input that exceeded the threshold of one or more of the electromechanical sensing elements.
