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: Methods and apparatus of stabilizing images used to track an object wherein the images are subject to slurs due to vibrations that are oscillatory in nature is provided. The methods include determining the center of intensity in the images taken of the object and using the center of the intensity to track the object.

Abstract: A sensor node for a wireless sensor network is provided. The sensor node comprises a sensor module including one or more sensors, a data processor in operative communication with the sensor module, a radio frequency transceiver in operative communication with the data processor, and an inertial measurement unit in operative communication with the radio frequency transceiver. A power source is coupled to the sensor module, the data processor, the radio frequency transceiver, and the inertial measurement unit. The inertial measurement unit is configured to determine a location of the sensor node during initial deployment of the sensor node in the sensor network.
