Emergency telephone communications device

Claim 1

An apparatus for emergency dialing and one-way communication by telephone comprising: a telephone dialer circuit for dialing a preselected emergency number and establishing a telephone line connection; a microphone connected to said telephone dialer circuit for sensing and transmitting sound from the vicinity of the microphone upon the telephone line connection being established; manually operable switch means electrically connected to said telephone dialer circuit for activating said circuit and causing the dialing of the preselected emergency telephone number on a telephone line to contact an emergency services operator; and said apparatus being characterized by the absence of a connection to a speaker during all periods when a telephone line connection is established so as to preclude audio communication from the emergency services operator.

Claim 2

An apparatus for emergency dialing and one-way communication by telephone comprising: a telephone dialer circuit for dialing a preselected emergency number and establishing a telephone line connection; a microphone connected to said telephone dialer circuit for sensing and transmitting sound from the vicinity of the microphone upon the telephone line connection being established; manually operable switch means electrically connected to said telephone dialer circuit for activating said circuit and causing the dialing of the preselected emergency telephone number on a telephone line to contact an emergency services operator; and said apparatus being characterized by the absence of a connection to a speaker during all periods when a telephone line connection is established so as to preclude audio communication from the emergency services operator.

Claim 3

An apparatus for emergency dialing and one-way communication by telephone comprising: a housing adapted to be mounted in a concealed location accessible to a user; an emergency switch mounted to said housing; a telephone line connection jack mounted to said housing; a telephone dialer circuit mounted n said housing and connected to said emergency switch and said telephone line connection jack for dialing a preselected emergency telephone number and establishing a telephone line connection to an emergency services operator responsive to activation of said emergency switch; and a microphone connected to said telephone dialer circuit for sensing and transmitting sound upon establishment of a telephone line connection, said apparatus being characterized by the absence of a speaker connection during all periods when a telephone line connection is established so as to preclude audio communication from the emergency services operator.

Claim 4

An apparatus for emergency dialing and one-way communication by telephone comprising: a housing adapted to be mounted in a concealed location accessible to a user; an emergency switch mounted to said housing; a telephone line connection jack mounted to said housing; a telephone dialer circuit mounted n said housing and connected to said emergency switch and said telephone line connection jack for dialing a preselected emergency telephone number and establishing a telephone line connection to an emergency services operator responsive to activation of said emergency switch; and a microphone connected to said telephone dialer circuit for sensing and transmitting sound upon establishment of a telephone line connection, said apparatus being characterized by the absence of a speaker connection during all periods when a telephone line connection is established so as to preclude audio communication from the emergency services operator.

Claim 5

An apparatus for emergency dialing and one-way communication by telephone comprising: a housing adapted to be mounted in a concealed location accessible to a user; a power source; an emergency switch mounted to said housing for, upon actuation, connecting said telephone dialer circuit to said power source and to said telephone line connection jack; said telephone dialer circuit having an internal telephone for establishing a telephone line connection to an emergency services operator, a preprogrammed sequencer for communicating an emergency telephone number to the internal telephone, and a timing pulse generator for providing timing to the sequencer; and a microphone connected to said telephone dialer circuit for sensing and transmitting sound upon establishment of a telephone line connection, said apparatus being characterized by the absence of a speaker connection during all periods when a telephone line connection is established so as to preclude audio communication from the emergency services operator.

Claim 6

An apparatus for emergency dialing and one-way communication by telephone comprising: a housing adapted to be mounted in a concealed location accessible to a user; a power source; an emergency switch mounted to said housing for, upon actuation, connecting said telephone dialer circuit to said power source and to said telephone line connection jack; said telephone dialer circuit having an internal telephone for establishing a telephone line connection to an emergency services operator, a preprogrammed sequencer for communicating an emergency telephone number to the internal telephone, and a timing pulse generator for providing timing to the sequencer; and a microphone connected to said telephone dialer circuit for sensing and transmitting sound upon establishment of a telephone line connection, said apparatus being characterized by the absence of a speaker connection during all periods when a telephone line connection is established so as to preclude audio communication from the emergency services operator.
