Abstract: A method and system allowing for the use of traditional buttons and switches to operate sophisticated features of smart appliances when a smartphone, a tablet, or a computer is not available is provided. Wall switches with existing wiring in a building or buttons on appliances can be used when a smartphone or other remote controlling devices are not available. A normally-closed (NC) wall switch or button can be used to control a smart appliance with only a power line connection in between the NC switch and the smart appliance without a wireless connection, or additional wires to send control signals.

Abstract: A telephone line connection and disconnection circuit has a diode bridge coupled to the telephone line which converts different voltages of the telephone line into a voltage referenced to ground. A switching circuit is coupled to the diode bridge which opens and closes a conductive pathway for connecting and disconnecting a telephony product from the telephone line. A resistive element is coupled to the diode bridge and the switching circuit which allows for the conductive pathway to be normally closed. An optical isolator is coupled to the switching circuit and the resistive element for sending a control signal to the circuit when required.

Abstract: An internet telephone system is disclosed. The internet telephone system is comprised of an internet system, a public switched telephone network (PSTN) coupled to the internet system, and a plurality of internet telephone stations coupled to the PSTN. In the internet telephone system a first internet telephone station establishes a PSTN telephone connection to a remote number, and upon coupling to a second internet telephone station at the remote number, the first and the second internet telephone stations exchange their names and IP addresses, terminate the PSTN telephone connection and then automatically establish an internet telephone TCP/IP connection.

Abstract: An internet telephone system uses a Public Switched Telephone Network (PSTN). An internet network is coupled to the PSTN. At least two telephone stations are part of the system wherein one of the at least two telephone stations is a DSL telephone station which is coupled to the PSTN. The DSL telephone station has a Plain Old Telephone Set (POTS) splitter coupled to the PSTN for directing low frequency signals to a first line and DSL signals to a second line. A DSL line interface is coupled to the POTS splitter for driving and terminating the second line. A DSL transmitter is coupled to the DSL line interface. A DSL receiver is also coupled to the DSL line interface. A Digital Signal Processor (DSP) is coupled to the DSL transmitter and the DSL receiver. A telephone interface is coupled to the first line. An audio transceiver device is coupled to the telephone interface. A CODEC circuit is also coupled to the telephone interface. A ring and hook detect/control circuitry is coupled to the DSP.

Abstract: An apparatus and method for subscriber loop powered calling identity delivery on call waiting apparatus provides battery only operation or extended battery life in a calling identity apparatus intended for off-hook and on-hook operation. The apparatus and method of using comprises a caller identification data receiver coupled to the subscriber loop for decoding caller identification tones and a CAS tone detector for detecting an alerting signal having at least one tone detector power supply input. Further comprised is a power supply circuit wherein the power supply's input is coupled to the subscriber loop for supplying power from the subscriber loop to the CAS tone detector.

Abstract: An intelligent caller identification apparatus for notifying a selected telephone number of the arrival of special electronic information. An information/internet service provider (ISP) calls a subscriber when an electronic communication has arrived. A microcontroller is used to compare the incoming telephone number to telephone numbers stored in an ISP database. If the incoming telephone number matches information stored in the ISP database, an information indicator circuit is set to inform the user of the arrival of an electronic communication. A ringing control circuit is used to prevent the telephone set from ringing when the incoming telephone number matches an ISP telephone number. The ringing control circuit thereby prevents the user from answering the incoming telephone call when the incoming telephone call is for notification of an electronic information delivery.

Abstract: A calling party identifying apparatus electrically connected to an exchange system which can provide the calling number and the registered name of the phone set or the like includes a receiver, a microprocessor, a memory, an LCD, a key pad, a plurality of lights, and a speaker. The memory has a database installed therein including a plurality of potential callers' information each of which includes a specific caller's name, the calling number of the caller, the preference degree thereof, and the preferred hours for the caller to call. The apparatus is allowed to display the caller's name on the LCD instead of displaying the registered name of the calling device. When any call comes in, the apparatus will check the database and display the caller's name, the calling number thereof, and the preference degree thereof.
