A Russian inventor has come up with a modern take on a popular Victorian invention, and developed
a coffin with a panic button which, should you be buried alive, you can press to alert someone to exhume you. The button conveniently glows in the dark; it is not clear how it works, though I'd guess it connects to the mobile phone network. Of course, if the embalmers get to you before you're buried, it'll be too late.
