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.

Claims

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.

2. A silent awakening system as defined in claim 1, wherein said first means comprises a housing with a compartment therein, an electric circuit is disposed in said compartment and receives an electric current from an external source, an electric relay provided in said electric circuit at the output section thereof, an acoustic receptor means disposed in the wall of said housing and connected to said electric circuit for transmission of an electric current therefrom to said electric relay for actuation thereof when said acoustic receptor means receives a sound signal from a fire-detector alarm, a telephone bell, and the like.

3. A silent awakening system as described in claim 1, wherein said second means comprises a step-down transformer having the primary coil thereof connected to a 115-volt alternating current and the secondary coil thereof connected to a full-wave rectifying circuit in electrical connection with said first means to energize said first means for actuation of the electric relay means connected thereto.

4. A silent awakening system as described in claim 2, wherein said housing is provided in one wall thereof a switch means electrically connected between the electric circuit disposed in the compartment of said housing and the electric relay to activate and deactivate said electric relay.
