## Abstract

An electric blanket is controlled so that it initially provides cozy warmth at low ambient temperature, but on reaching deep sleep phases, temperature is lowered, for as much dissipation of calories as it does not disrupt the sleep.

## Claims

### Claim 1

Electrically heated blanket with sleep depth-dependent control for weight loss, wherein the blanket has no significant thermal insulation effect.

### Claim 2 (depends on 1)

Electrically heated blanket as to claim 1, wherein the heating is controlled in response to sleep phases.

### Claim 3 (depends on 1)

Electrically heated blanket as to claim 1, wherein the the sleep phases are determined by motion sensors in the blanket, connected to an recording logic.

### Claim 4 (depends on 3)

Electrically heated blanket as to claim 3 wherein coming sleep phases are predicted by evaluation of registered prior devolutions.

### Claim 5 (depends on 1)

Electrically heated blanket as to claim 1, wherein renewed pressure on the start button prior to passage of an ordinary sweep is registered as incident due to possible temperature undercut.

### Claim 6

Electrically heated blanket as to one or more of the preceding claims, wherein the switch-off of the heating is also used for or at least supporting waking up of the user at reveille time.
