Assignee:

The United States of America, as respresented by the Secretary of the Navy - Washington DC

International Classification:

G08B 13/00

US Classification:

340566, 340565, 340551, 340541, 367118, 367124

Abstract:

A method and system for detecting and classifying intruders is provided. A noise threshold can be determined and set based on background noise. A seismic sensor can be configured to receive a plurality of seismic data signals. A microcontroller can be configured to count the number of times the noise threshold is exceeded over a defined time interval by the plurality of seismic data signals, and then detect and classify the presence of an intruder based on the count. Additionally, an amplitude evaluation module can be configured to determine a signal amplitude for the seismic data signals associated with the detected intruder and compare the detected intruder signal amplitude to known signal amplitudes in order to determine a sub-type of the intruder. Finally, a transmission source can be configured to transmit intruder detection and classification information to a remote location.

Abstract:

An apparatus as provided for measuring acceleration of a person's head or other object. The apparatus comprises a sensor for sensing acceleration and a controller for controlling recording of data resulting from the sensed acceleration due to an explosive force. The controller is adapted to determine whether or not to enable recording of the data based on the sensed acceleration. A data receiver is provided to receive the sensed acceleration data from the sensing means, and requires electrical power to enable data to be received thereby. The controller controls electrical power to the receiver so that if the sensed acceleration reaches or exceeds a predetermined value, electrical power to the data receiver is enabled. The recorded acceleration data may be used for injury analysis.
