Multiple functional systems are integrated to configure a portable handheld decision-aid device for first responder medics. Fuzzy membership functions of 'life' and 'death' are used to determine the status of fallen people using remote measurements. EO/IR cameras can be used to detect and identify casualties in a mass injury situation, while also estimating body temperature. Using the temperature, along with the remote estimation of a second vital sign, the life membership proportion can be estimated from the ground truth by using a 2D projection of stable vital signs. The other fuzzy membership function, death, can be estimated by the presence or absence of peri-mortem and post-mortem molecules. These molecules are only released after death and provide a certain indication of death. Solid state UV laser resonance Raman backscattering from these molecules allows the device to analyze the molecules present in a plume around the casualty.

Hand-held raman laser device for distant life-death determination by molecular peri-mortem plume fuzzy membership function

A multiple output wavelength laser and technique for generating multiple put laser wavelengths from a solid state lasing material. The solid state material must be able to lase at multiple nonoverlapping transitions such that there are no losses due to gain competition or divided output power.
