Abstract

Abstract A telephone calling system provides in response to received ringing pulses; (1) circuit closure disabling the ringing circuit and enabling the voice communication circuit; (2) turns on an answering device which transmits ''''you have reached the phone of Mr. Smith. I am in the back yard. Please hold the line until I can get to the phone''''; (3) sends out a signal to activate a remote signaling device, and; (4) a remote wrist radio device provides an audible, visible and/or other signal indicating that a call has come in on the telephone circuit. The standard telephone provides an audible signal in the form of a bell which is energized by pulsing current over the line to indicate an incoming call. In case it is undesirable to have an audible signal, a visible signal in the form of a blinking lamp may be substituted. Whenever an individual on the receiving end is within range of these signals, there is no particular problem. However, the ranges of these audible and/or visible signals are definitely limited. There are many and growing situations where the intended recipient is out of range of the signal or signals. Examples are when one is in another part of a large rambling house, outside, in another room with the door closed, in a neighbor''s back yard, and any number of other possible situations.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 118 words
In a remote telephone calling system, the combination of; means for closing a circuit in response to a telephone ringing signal; means for connecting a line seizing load through said circuit closing means to a telephone line; a message playing device coupled to said circuit closing means and including voice signal output means; a means for coupling said voice signal output means to said telephone line to repeat a predetermined message into said line; remote calling means energizable in response to said circuit closing means; and coupling means between said circuit closing means and said remote calling means for energizing said remote calling means in response to the presence of a telephone ringing signal on said telephone line.
Claim 2
Dependent Claim 118 words
In a remote telephone calling system, the combination of; means for closing a circuit in response to a telephone ringing signal; means for connecting a line seizing load through said circuit closing means to a telephone line; a message playing device coupled to said circuit closing means and including voice signal output means; a means for coupling said voice signal output means to said telephone line to repeat a predetermined message into said line; remote calling means energizable in response to said circuit closing means; and coupling means between said circuit closing means and said remote calling means for energizing said remote calling means in response to the presence of a telephone ringing signal on said telephone line.
Claim 3
Dependent Claim 30 words
A remote telephone calling system as set forth in claim 1; wherein said remote calling means comprises a tone modulated radio frequency signal generator coupled to radio frequency antenna means.
Claim 4
Dependent Claim 22 words
A remote telephone calling system as set forth in claim 1; and including remote receiving means responsive to said remote calling means.
Claim 5
Dependent Claim 30 words
