Abstract: A security sensor system comprises one or more laser detection and ranging (LADAR) sensors configured for accumulation of three-dimensional image data. In one embodiment, the one or more LADAR sensors each comprise a LADAR device, such as a MEMS device, configured to transmit a plurality of laser pulses, and a microprocessor operatively coupled to the LADAR device. One or more data storage devices is operatively coupled to the microprocessor and configured to store the three-dimensional image data, as well as predetermined protected area boundary and fixed object definitions. A GPS receiver can be operatively coupled to the microprocessor and a GPS antenna. The microprocessor is configured to perform a LADAR image analysis that compares the three-dimensional image data with the protected area boundary and fixed object definitions to identify one or more potential intruders.

Abstract: A method for wireless communication in a seismic sensor network is disclosed. The method comprises providing a first acoustic device having at least one seismic sensor with communication and control data to communicate over an acoustic energy wave on a first communications channel. The first acoustic device generates the acoustic energy wave with a first wave intensity. The first acoustic device is configured to receive a reflection of the generated wave at a prescribed signal sensitivity level based on a network configuration. If the first wave intensity is below the prescribed signal sensitivity level, the first wave intensity of the acoustic energy wave is tuned to the prescribed signal sensitivity level to interpret the communication and control data provided by the first communications channel.

Abstract: A method for tracking motion using an audio compass is disclosed. The method comprises receiving motion sensor data indicating seismic activity recorded by at least two seismic sensors, and converting the received motion sensor data into audio signals for interpretation at an audio compass. The method uses the audio compass to determine a current distance to the seismic activity based on an interpreted signal intensity of the audio signals. The method further uses the audio compass to identify a current position of the audio compass relative to the seismic activity.
