  • Patent number: 8345846
    Abstract: The present invention is directed to a telephony communication interface device. The device includes a communication transceiver configured to communicate with a remote system via a predetermined communication channel. A control circuit is coupled to the communication transceiver. The control circuit is configured to determine a device operating mode status based on communication transceiver activity. The device operating mode status includes a telephonic communications mode and a remote system communications mode. An interface circuit is coupled to at least one telephone set. The interface circuit is configured to propagate voice telephony signals between the at least one telephone set and a telephony network in a telephonic communications mode and propagate voice intercom signals between the at least one telephone set and the communication transceiver in the remote system communications mode.

  • Patent number: 8345845
    Abstract: An improved public intercom system is described which has a sealed enclosure including an extruded chassis having a front wall and a rear wall. The front wall has an interface panel and a viewing panel mounted within cutouts. A plurality of axially aligned module cover plates supporting system components are mounted over cutouts in the rear wall. The interface includes a speaker, a microphone, a call initiation means, and a camera positioned to acquire images of the area in front of the interface panel. One of the cover plates including an outer surface with heat dissipation protrusions, with a blower located on said rear wall being oriented to direct air across the protrusions to extract heat from the chassis interior. A two-way communication means is mounted on a module plate and programmed to initiate a call to a pre-programmed receiver responsive to a command from the call initiation means.

  • Patent number: 7792259
    Abstract: Irrespective of the distance of a line through which a video signal is taken by the camera of a main entrance station, a satisfactory image having not deterioration but excellent visibility is displayed in a monitor of a residential master station. A distance decision unit of a residential master station for displaying a video signal taken by a camera of an main entrance station in a monitor decides the distance of the line length of a master station line in terms of the voltage drop of the DC power supply fed from a controller to the residential master station. A level compensation unit of the residential master station compensates the level of the video signal in accordance with the decided distance. A distance decision unit of the main entrance station decides the distance of the line length of an entrance line in terms of the voltage drop of the DC power supply fed from the controller to the main entrance station.

  • Patent number: 7764775
    Abstract: A distributed intercom system including a centralized interconnection unit with a central control device for receiving, processing and transmitting signals, a power distribution device for transmitting a power signal for distribution and at least one cable connection port for receiving a cable connection therein. The system includes a cable with a cable connection element for connection to the cable connection port, and the cable transmits a control signal, a line-level, analog audio signal and the power signal. One or more remote user interface units are connected to and in communication with the centralized interconnection unit through the cable, and the remote user interface unit includes an amplifier, a speaker device and a microphone device. At least one component of the remote user interface unit is powered by the power signal transmitted by the power distribution device.

  • Patent number: 6760419
    Abstract: A method and system for interconnecting a telephone system and an intercom system. In one exemplary embodiment, telephone switchgear is connected to a telephone interface which provides separate voice transmit and receive channels. For example, an E&M tie line module can be utilized, which also includes E&M signaling connections for signaling an incoming intercom call to a telephone and for signaling an outgoing telephone call to an intercom. In this exemplary embodiment, an interface circuit is also provided to allow for signal level adjustment along the transmit and receive channels, such that the signal gain of the telephone system can differ from the signal gain of the intercom system. The interface circuit can include a controller which controls a switching device for selectively allowing communication along the transmit and receive channels during periods when communication is desired.
