Promotion of sleeping by rhythmic stimuli - using intermittent electrical pulses in induction circuit around sleeping area

摘要

Sleep is promoted by rhythmic stimuli carried out by surrounding the sleeping area with an induction circuit in which an electrical impulse is conducted at regular intervals. Appts. comprises a pulse generator and a frame-like induction circuit connected in series. The latter is attached to a pillow and/or to a bed surround. The pulse generator is pref. supplied with low voltage by a main lug transformer, and the number of pulses is regulated to 59-61. The frequency is thus set by the daytime frequency which any user can measure easily himself from the pulse count. Heart and respiratory frequencies are adjusted to this level and provide readiness to sleep.
