Abstract: An integrated messaging system uses existing messaging equipment to receive, store, retrieve and manage messages in media types and formats appropriate to each existing system using protocols which are specific to that system. Two or more systems are tightly coupled in that a message received in one system can be accessed from all systems. Coordination between messaging systems is achieved by a synchronizer system which periodically connects to each system by means of a standard interface and insures that messages created or received in one system are distributed or identified in all other messaging systems. Thus, the messaging systems can operate together even though they have different user interfaces, storage designs and formats and access and routing protocols. In one embodiment, a message received in one system is copied to the other system. In another embodiment, the header information in a message is preserved in a message created in the other system, but the message is not copied.

Abstract: A system for changing the activation status of a selected data card such as a charge card by broadcasting an appropriate RF signal. An antenna embedded in the card detects and decodes the signal, and operates a transducer which changes the card appearance, alters magnetic stripe information, or alters the information contained within the card.

Abstract: Electrical consumption registered in a watthour meter is converted into an electrical analog suitable for transmission to a remote monitoring site by reflecting light off the watthour meter rotor, the light being periodically interrupted during each rotor rotation by a darkened light absorbing area of the rotor which traverses the light beam, passing the light to and from the meter through fiber optic cables and digitally counting at a distant location each of the pulses corresponding to the rotor rotation which are transduced from the light reflections. By generating the light from an AC signal, AC signal processing techniques employed in the light reflection detection circuitry ensure a useable electrical analog with minimal likelihood of error otherwise arising from spurious noise and varying ambient temperature related signals.
