Abstract
A wearable universal blast sensor includes an underwater pressure sensing transducer and at least one blast parameter sensing transducer to measure a blast parameter from the blast other than pressure, an analog-to-digital converter having an analog input and a digital output, the analog input coupled to the pressure sensing transducer and a digital output, a rolling memory buffer coupled to the digital output of the analog-to-digital converter, at least one controller coupled to the rolling memory buffer and configured to store a time sequence of digital pressure signals from the digital output of the analog-to-digital converter, write into a blast event memory data from the rolling memory buffer including data corresponding to the blast event if one of the digital pressure signals exceeds a set first threshold, generate a first blast magnitude indicator signal if any of the digital pressure signals exceeds a second set threshold.
