Abstract: A method of detecting and locating a fluid leakage in a fluid pipeline network includes providing a plurality of sensors in an area of the pipeline network. Each sensor is configured to output data relating to an acoustic or vibration measurement associated with a part of the pipeline network proximate said sensor. The method further including recording the acoustic or vibration measurement output data, transforming the output data from a time domain to a frequency domain, determining a leakage condition, computing a sum value of the measured frequency values and associating said sum value with a corresponding sensor of the plurality of sensors, and locating a source of the fluid leakage by identifying one or more sensor(s) of the plurality of sensors in the area of the pipeline network that is closest to the source of the fluid leakage.

Abstract: Some embodiments relate to a vibration sensor. The vibration sensor comprises: a sensor base to couple to a vibration source; a piezoelectric transducer coupled on a first side of the transducer to the sensor base; at least one conductor coupled to the piezoelectric transducer; and a seismic weight positioned on a second side of the piezoelectric transducer; wherein the sensor base, the piezoelectric transducer and the seismic weight are aligned along an axis and arranged so that relative movement between the sensor base and the seismic weight arising from the vibration source causes a current to be generated in the piezoelectric transducer and an output signal corresponding to the generated current is detectable on the at least one conductor.

Abstract: Some embodiments facilitate remote monitoring of an activity at one or more facilities by a vehicle. Data is received at a communications interface from a remote device that is co-located with the vehicle. The data includes a vehicle identifier and a vehicle location indicator. A zone data record is accessed. The zone data record includes a plurality of zones, each zone having a virtual geographical boundary associated with a physical geographical area including at least one facility. It is determined that the vehicle is located within a zone of the zone data record for a preconfigured period of time based on the vehicle location indicator and the zone data record. Responsive to determining that the vehicle is located within the zone for the preconfigured period, performance of the activity at the one or more facilities by the vehicle is determined.
