    Abstract: Disclosed are buried cable protection systems and methods that employ impulse signal detection by optical fiber sensing technologies, and which provide such protection automatically and in real-time. The methods theoretically model a time difference of arrival (TDoA) of an impulse wave travelling to a DFOS sensor fiber cable. A model employing a set of propagation relationships that account for vague knowledge about wave propagation speed and threat range(s) is fitted with parameters based on a numerical simulation - without specific knowledge of a source of vibration. As compared to vibration magnitude information, time of arrival (ToA) information is more consistent and less sensitive to ambiguities and inaccuracies. In addition, the model parameter can be adjusted adaptively when temporal resolution of the sensor changes or fluctuates. As a result, our inventive systems and methods effectively detect impulse signals from machines or other activities generating vibratory impulse ground events at different distances to a fiber optic cable and distinguish same from background noises including those caused by transportation modes such as train or vehicular traffic.

    Abstract: A very high resolution sensor for detecting an angular rotation of a rotating target, the sensor including a first pair of Hall effect sensors and a second pair of Hall effect sensors. A first magnetic flux density differential of the rotating target is generated from the first pair of Hall effect sensors and a second magnetic flux density differential of the rotating target is generated from the second pair of Hall effect sensors. A pulse corresponding to an amount of angular rotation of the rotating target is output based on the second magnetic flux density differential reaching the first magnetic flux density differential.
