Abstract: A computer keyboard having duplicates of the Enter key, the Delete key, and the Backspace key to the left side of the main keyboard keys for cooperative operation by the left hand during editing functions while the right hand manipulates the computer mouse.

Abstract: A plurality of Integrated Devices are provided with an Internet connection and a telephone number. The telephone number has associated telephone connectivity via a telephone line, such that the Integrated Devices can be connected to by dialing the associated telephone number via telephones on the Public Switched Telephone Network (PSTN). The Internet connection has an associated Internet protocol (IP) address which is dynamically assigned when one device calls the telephone number of a called device via the PSTN. The dynamically assigned IP address for a first one of the calling or called device is provided to the other device, which initiates an Internet connection between them by sending an Internet message to the dynamically assigned IP address of the first device. Local and intermediate proxy servers perform dynamic IP address management, providing privacy and security for user IP addresses and data transmissions.

Abstract: An Interactive Device Control System has a method and means for providing device control, call control, and communications system information for telecommunications and Internet voice and multimedia communications. A communications system, service, or device offers the user of a communications device having a display screen, such as a screen phone, the ability to control or influence the functions of the communications system. The PSTN establishes and controls Internet communications between communications systems and user devices. Messages comprising information to be presented on the user's display are sent from the communications system, service, or device, and interactive responses from the user indicate the selected control function. Call control messages from the communications system to the PSTN execute the desired control function, such as transferring the call.

Abstract: A stored profile system has a method and means for storing and exchanging user profiles of communications-related information for voice and multimedia communications on the PSTN and the Internet. Stored profile exchanges from a called party device to a calling user enables the calling user to direct the call to telephone numbers and services presented by the called party's profile. Users are enabled to transmit information, such as an Electronic Business Card, in the call setup process for display on a receiving device. The stored profile system operates across the Public Switched Telephone Network (PSTN) and the Internet, further enhancing the benefits of integrating the Internet with the PSTN.

Abstract: A call management messaging system enables the integration of the Internet with the Public Switched Telephone Network PSTN in a manner such that systems, services, and devices on either can communicate with systems, services, and devices on the other. The full benefit and unique characteristics of either network are thereby made available to these communications. Call management messages include call setup requests, call acceptance, call rejection for busy, call forwarding, and similar messages necessary for creating and disconnecting voice and multimedia communications across the PSTN or the Internet. Devices on both the Internet and the PSTN have messaging addresses, and are associated with the call management messaging system. A device creates an Internet communication with another device by dialing its telephone number.

Abstract: Telephone central office-switching system integrated interface devices such as those for DSL, Voice over IP, cable-TV, fixed wireless, and Internet capable wireless cellular are further integrated into integrated interface device systems. Such systems share common facilities including a router function, messaging function, and a common voice communications channel. The messaging function is arranged to provide call setup and associated messages which enable a calling device which calls an Integrated Device to establish an Internet communication simply by dialing the telephone number of the Integrated Device. Integrated Devices have both an Internet connection and a telephone number; the Internet connection has an associated IP address. Call setup messages include telephone numbers and IP addresses. The integrated router function is enabled to edge route Internet data traffic within the system and to and from other such systems, without the data traversing further into the Internet.

Abstract: A method and means for a telephone central office switching system facilitate integration of the Internet and the Public Switched Telephone Network. The method and means enable specific messaging communications from the telephone central office switching system to (i) individual terminal devices, (ii) interface devices that provide Internet and telephony services for their client devices, and (iii) other telephone central office switching systems. Such integration enables a calling device to achieve an Internet communication with a called device by dialing the telephone number of the called device.

Abstract: Integrated Devices enable the integration of the Internet with the Public Switched Telephone Network (PSTN). A device can place a telephone call to an Integrated Device via dialing on the PSTN and have the call consummated over the Internet via a mechanism of messaging between the associated devices and systems.

Abstract: A plurality of Integrated Devices are provided with an Internet connection and a telephone number. The Internet connection has an associated Internet protocol (IP) address permanently or dynamically assigned. It is initiated when one device calls the telephone number of a called device via telephones on a public service telephone network (PSTN). The telephone number has associated telephone connectivity via a telephone line, such that the Integrated Devices can be connected to by dialing the associated telephone number via telephones on the PSTN. An Internet connection is associated with the calling device; the called device is an Integrated Device. An IP address for a first one of the calling or called devices is obtained and provided to the other device, which initiates an Internet connection therewith by sending an Internet message to the IP address thereof.

Abstract: Integration of the Internet with the Public Switched Telephone Network (PSTN) is facilitated for Voice over IP communications by incorporating an enhanced Voice over IP interface device with a messaging communications link to a telephone central office switching system. The communications link carries call setup, telephone number, and IP address messages to and from the switching system. Communications are facilitated by enabling messaging communications from the telephone central office switching system to individual devices.

Abstract: An Enhanced Radio Data System for commercial radio broadcasters comprises a subcarrier modulated for transmitting data impressed on the broadcaster's main carrier frequency. The subcarrier data protocol constitutes an enhancement over existing protocols constructed for this purpose by providing the capability for broadcasters to identify themselves both by their program format as well as by the announcements they carry, and by providing the capability for broadcasters to convey more detailed information in a process with greater inherent intelligence. Such intelligence enables: data typing without separately transmitting the definition of the data types; data compression specific to each type of data; and data formatting and presentation based on the specific characteristics of the data types without the need to separately transmit data formatting and presentation instructions.

Abstract: An enhanced radio graphic data system comprises an FM receiver, RDS demodulator and decoder, display, microprocessor and memory. The system incorporates a protocol enhancement of RDS involving the redefinition of several bits within the B-block. An accompanying arrangement utilizes data in the C- and D-Blocks to create message streams containing the text data to be presented along with associated formatting instructions.
