Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
A subscriber presence detector system comprising: (a) a switching system for connecting calls to and from a plurality of lines, (b) a person presence detector connected to a line, for automatically providing an indication to the switching system that a particularly identified person is adjacent or not adjacent said detector, (c) means for storing said indication at the switching system comprised of an identity of the particular subscriber, (d) means for enabling a security device by said switching system upon the switching system receiving and storing said indicating that said identified person is adjacent said detector, and (e) the security device being at least one of an amplified microphone and a video camera disposed adjacent said line, and further including a separate transmission medium for transmission of at least one of sounds and images at a remote location from said at least one of an amplified microphone and video camera of said security to a monitoring location.
Claim 2
Dependent Claim
157 words
A subscriber presence detector system comprising: (a) a switching system for connecting calls to and from a plurality of lines, (b) a person presence detector connected to a line, for automatically providing an indication to the switching system that a particularly identified person is adjacent or not adjacent said detector, (c) means for storing said indication at the switching system comprised of an identity of the particular subscriber, (d) means for enabling a security device by said switching system upon the switching system receiving and storing said indicating that said identified person is adjacent said detector, and (e) the security device being at least one of an amplified microphone and a video camera disposed adjacent said line, and further including a separate transmission medium for transmission of at least one of sounds and images at a remote location from said at least one of an amplified microphone and video camera of said security to a monitoring location.
