Abstract:

A method and computer program product instituting an entirely client-based system for sharing messages and other data objects is provided. Communication between clients occurs over a generic store and forward transport such as the Internet message protocol described in RFC 822 and implemented on the Internet or other wide area network. A message or other data object is originally maintained by a "publication" client that publishes the data object and any modifications thereto to one or more "subscription" clients that will each maintain a copy thereof. As modifications are made by a client (either publication or subscription) to the client copy of the data object, the modified data object is sent, using the store and forward transport, to the publication client to update the data object. Once the data object is updated by the publication client, copies of the modified data object are sent using the store and forward transport to each subscription client so that the subscription client may update the subscription copy. One embodiment of the present invention designates a messaging folder containing one or more data objects as a publication folder (managed by a publication client) that is replicated out to subscription clients over the store and forward transport.

Abstract:

A computerized multicolor camera is disclosed that provides digital signal representations of several monocolor images of an object. The camera has an image sensor with an imaging region that develops a charge pattern in response to incident light reflected from the object through a selectable color filter to the imaging region. This analog charge pattern for each selectable color is digitized, the computer within the camera corrects the digitized values for nonlinearities of the image sensor, and stores the corrected digital values in its internal memory. The computer within the camera can then transfer the digital representations of the image to an external computer via a SCSI interface. In addition, the camera has an analog output mode that generates a monocolor real time video signal.
