Abstract: The usage detection system establishes a suppressed ringing connection to the subscriber line for either a predetermined extended time interval to enable at least two successive usage readings to be taken, or for a duration as determined by the telemetry equipment to perform the necessary usage readings to detect the presence of usage anomalies. This usage detection system communicates with the serving central office to establish a suppressed ringing connection, the duration of which is either under the control of the usage detection system or the telemetry equipment located at the customer premises. The usage detection system communicates with the telemetry equipment to identify the usage measurements that are desired.

Abstract: An interactive interface facilitates the setting of preferences and other programmable parameters of an appliance. The interface is hosted by a server on a global computer network. The appliance owner initiates a connection to the server and is presented with a graphical user interface for setting the preferences and features of the appliance. Once the desired settings have been made, they are downloaded to the appliance either directly from the server or the appliance owner's computer or indirectly using a portable transfer device.

Abstract: An earphone system includes a remote control unit for transmitting a first control signal, and an earphone section operatively connected to a terminal equipment and said remote control unit. The earphone section includes a connector to be operatively connected to the terminal equipment, an earphone speaker section for outputting an audio output from an audio output signal, and a microphone for inputting an audio input to produce an audio input signal. A remote control signal processing section receives the control signal from the remote control unit. A remote control modulating and demodulating section is connected to the earphone section via a first cord and is connected to the connector via a second cord. The remote control modulating and demodulating section passes the audio input signal to the terminal equipment via the connector and the audio output signal from the terminal equipment via the connector to the earphone speaker section.

Abstract: A telephone operates as a time server for synchronizing an appliance or peripheral by accessing a time service over telephone lines to obtain an accurate geographic time for the telephone, and by transmitting a synchronizing pulse to the appliance at a predetermined time to set the time function of the appliance.

Abstract: A videophone apparatus with an on-screen telephone keypad user-interface. The videophone communicates video and audio data over a plain old telephone service (POTS) line and includes a video source and a communication channel interface circuit coupled to a programmable processor. The programmable processor is configured and arranged to execute a user interface program for user controlled operation of the videophone apparatus, display a first menu on the display, the first menu referencing a first plurality of options for operating the videophone apparatus and having associated therewith respective indicators of telephone keypad buttons, receive from the telephone keypad a first selection signal indicative of a pressed button, and initiate an operation to control the videophone apparatus in response to the first selection signal.
