Yes, there are EPIRBs (Emergency Position Indicating Radio Beacon) specifically meant for avalanche location. They tend to help more in more highly frequented areas, where rescuers can respond to an avalanche quickly, to find buried victims faster, before they expire (vs the old school approach of a row of people with snow probes).
With backcountry skiing, like in these incidents though, they’re more likely to come in handy to find the bodies.
The avalanche airbags greatly increase the likelihood of staying near the surface, so the person can self rescue.
