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.

Acoustic communication and control for seismic sensors

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.

Health monitoring in a system of circumvention and recovery

An adaptive digital power control system is disclosed, which implements a digitally controlled, near real-time algorithm to accommodate multiple loop current mode controls for low voltage, high performance computing system power needs. For example, an adaptive digital power control system that is implemented with an FPGA to generate low voltages for high performance computing systems is disclosed, which includes a current and voltage loop compensation algorithm that enables the adaptive digital power control system to dynamically compensate for high current transients and EMI-related noise. The current and voltage loop compensation algorithm uses a combination of linear predictive coding and Kalman filtering techniques to provide dynamic current and voltage compensation, and implement a feed-forward technique using knowledge of the power system's output parameters to adequately adapt to the system's compensation needs. More specifically, an adaptive digital power control system is disclosed, which includes a power stage for generating a plurality of low voltages, a multiplexer and A/D converter stage for receiving and converting the plurality of low voltages and a plurality of associated currents to a plurality of digital voltage and current signals, a current and voltage compensation algorithm stage for receiving the plurality of digital voltage and current signals and generating a plurality of digital voltage and current compensation control signals using linear predictive coding, Kalman filtering and feed-forward estimation techniques, and a digitally controlled pulse width modulator stage for receiving the plurality of digital voltage and current compensation control signals and controlling the duty cycles of a plurality of transistor switching devices in the power stage. Thus, the adaptive digital power control system can dynamically compensate for high current transients and EMI-related noise generated in low voltage power systems for high performance computing systems.
