sleep machine

Federation bunks have what we call a sleep machine.  You lie on the bunk, order,  “Sleep for,” a certain time, or, “Sleep until,” a certain time.  It puts you to sleep, but doesn’t make you unconscious, like a stun-gun.  Someone can waken you – by calling, or shaking you gently.

I told Geli how to use a sleep machine while I was showing her the cabin in the college on Yband 4.  See Report D.
