Abstract: In one embodiment, a system for simulating emergency events includes: a signal generator operatively coupleable to one or more detectors; and a controller operably coupled to the signal generator and configured to cause the signal generator to: generate one or more synthetic signals based at least in part on data comprising one or more of: trainee identity, trainee role, synthesized data, and one or more measurements taken during a simulation; and communicate the synthetic signal(s) to the detector(s) by injecting the synthetic signals) directly into a position of a receive path of the detector(s) that is upstream of signal processing electronics of the detector(s) and downstream of a sensor of the detector(s). The synthetic signal(s) is/are waveform signals representative of at least one emergency event; and the synthetic signahs) is/are utilized to mimic conditions during emergency event(s) and under particular emergency conditions. Corresponding methods and computer program prodcuts are disclosed.

Abstract: In one embodiment, a system includes a signal generator operatively coupleable to one or more detectors; and a controller, the controller being both operably coupled to the signal generator and configured to cause the signal generator to: generate one or more signals each signal being representative of at least one emergency event; and communicate one or more of the generated signal(s) to a detector to which the signal generator is operably coupled. In another embodiment, a method includes: receiving data corresponding to one or more emergency events; generating at least one signal based on the data; and communicating the generated signal(s) to a detector.

Abstract: A tailpulse signal generating/simulating apparatus, system, and method designed to produce electronic pulses which simulate tailpulses produced by a gamma radiation detector, including the pileup effect caused by the characteristic exponential decay of the detector pulses, and the random Poisson distribution pulse timing for radioactive materials. A digital signal process (DSP) is programmed and configured to produce digital values corresponding to pseudo-randomly selected pulse amplitudes and pseudo-randomly selected Poisson timing intervals of the tailpulses. Pulse amplitude values are exponentially decayed while outputting the digital value to a digital to analog converter (DAC). And pulse amplitudes of new pulses are added to decaying pulses to simulate the pileup effect for enhanced realism in the simulation.
