Silent awakening system
First Claim
1. A silent awakening system, comprising:
- a first means adapted to receive an acoustic signal and to convert said acoustic signal into an electrical signal, an electric amplifying means connected to said first means and having an electric circuit therein to amplify and transmit said electrical signal to an electric relay means for operation thereof, a second means, in electrical connection with said first means, receiving an alternating current from an external source and adapted to convert said alternating current into a direct current for energization of said first means, and a third electric circuit means connected to said second means to receive therefrom a direct current through said electric relay means therein to electrically process said direct current;
said third electric circuit means having in the current-processing circuit thereof a current-interrupting means, a variable current control means disposed therein in electrically parallel relation to said current-interrupting means, and a current-switching means, connected between the electrically parallel sections comprising said current-interrupting means and said variable current control means, to channel the direct current supplying said electrically parallel section into one or the other of said electrically parallel sections; and
, an awakening module in electrical connection with said third electric circuit means through said current outlet means to receive an electric current therefrom for operation of said awakening module by the actuation of said electric relay means upon reception of an acoustic signal by said first means.

Abstract
A silent awakening system operable either by receiving a sound-alarm signal, such as that from a fire-detection alarm, or by the actuation thereof by means of an alarm-triggering means of an electric clock, with the sound-producing mechanism of said clock being deactivated. The system is used to awaken deaf persons as well as persons of normal hearing, without disturbing others sleeping in the same room or nearby. It comprises a sound-receiving means which converts said sound to an electric signal to operate an electric relay, an electrical signal-processing circuit connected to said relay and actuated thereby, an electric alarm clock to set the time of awakening with the alarm-triggering means thereof mechanically connected to a switch means disposed in said electrical signal-processing circuit, and an awakening module electrically connected to said electrical signal-processing circuit to receive, for operation thereof, a processed current either through said electric relay or through said switch means actuated by the alarm-triggering means of said clock.
