Not precisely a temper decoder, however a “neural sensor.” The gadget would then ship a pulse of electrical energy.  

And it appeared to work. As Sarah mentioned at a press convention final yr: “My melancholy has been stored at bay, and that’s allowed me to begin rebuilding a life that’s value residing.”
