Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
140 words
An apparatus for annunciating the completion of a call hold interval in a telephone communication system to an active party and a passive party, said apparatus comprising in combination: voice detection circuit means responsive to the presence of a voice signal on the telephone communication line; an annunciation signal timer; means for connecting said annunciation timer to said voice detection circuit such that said voice detection circuit actuates said annunciation timer when said voice detection circuit senses the presence of a voice signal on the telecommunication line; and means for indicating to the active party and to the passive party when said annunciation signal timer has been actuated by said voice detection circuit thereby notifying the passive party that the active party has returned to the line and indicating to the active party that the telecommunication line is still active.
Claim 2
Independent Claim
140 words
An apparatus for annunciating the completion of a call hold interval in a telephone communication system to an active party and a passive party, said apparatus comprising in combination: voice detection circuit means responsive to the presence of a voice signal on the telephone communication line; an annunciation signal timer; means for connecting said annunciation timer to said voice detection circuit such that said voice detection circuit actuates said annunciation timer when said voice detection circuit senses the presence of a voice signal on the telecommunication line; and means for indicating to the active party and to the passive party when said annunciation signal timer has been actuated by said voice detection circuit thereby notifying the passive party that the active party has returned to the line and indicating to the active party that the telecommunication line is still active.
Claim 3
Dependent Claim
34 words
The apparatus as set forth in claim 1, wherein said indication means comprises an acoustical device, located proximate to the passive party, which emits an audible signal upon actuation by said annunciation signal timer.
Claim 4
Dependent Claim
33 words
The apparatus as set forth in claim 1, wherein said indication means comprises a tape player means which supplies a prerecorded message to the active party upon actuation by said annunciation signal timer.
Claim 5
Dependent Claim
66 words
the apparatus as set forth in claim 1, wherein said indication means comprises an annunciation signal generator which, upon being actuated by said annunciation signal timer, supplies a signal to a speaker means for audibly indicating to the passive party that the active party has returned to the line and to the telecommunication line to indicate to the active party that the telecommunication line is active.
Claim 6
Dependent Claim
78 words
The apparatus as set forth in claim 4, wherein said annunciation signal timer includes a monostable multivibrator whose output triggers said annunciation signal generator during a predetermined annunciation signal interval such that said annunciation signal timer may be retriggered after the expiration of the first annunciation signal interval thereby permitting the active party to indicate to the passive party that the active party has returned to the line and is awaiting the passive party's return to the line.
Claim 7
Dependent Claim
34 words
The apparatus as set forth in claim 5, wherein said annunciation signal generator comprises means for producing at least one audible tone which is supplied to said speaker means and to the telecommunication line.
Claim 8
Dependent Claim
36 words
The apparatus as set forth in claim 5, wherein said annunciation signal generator comprises means for producing three-tone bursts which are supplied to said speaker means and to the telecommunication line during the annunciation signal interval.
Claim 9
Dependent Claim
22 words
The apparatus as set forth in claim 5, further including means for deactuating said voice detection circuit during said annunciation signal interval.
Claim 10
Dependent Claim
28 words
The apparatus as set forth in claim 1, further including a switch means for manually connecting said voice detection circuit to a telecommunication line of a multi-line system.
Claim 11
Dependent Claim
58 words
The apparatus as set forth in claim 1, further including a bridging adaptor means and a multi-position switch means which enable the apparatus to be connected in line to a multi-line telephone communication system and which enable said voice detection circuit means to be manually connected to one of the telecommunication lines of the multi-line telephone communication system.
