  • Patent number: 11003842
    Abstract: A system and methodology for use by a plurality of users, each of the users having a display apparatus and an input apparatus. An underlying common display presentation is provided to all of the users as a base image display. A plurality of the users input annotations while the users are viewing the base image display. The annotation data from the annotations is stored in an addressable area of memory associated with the respective said user, for at least two of the users. A modified display presentation is shown to at least two of the users, comprised of the base image display combined with a video display image generated responsive to at least some of the annotation data for at least two of said users.

  • Patent number: 10796282
    Abstract: The assembling of a presentation for a user by processing selected sub-component parts method using structuring inputs into a plurality of sub-component parts in an ordered-linear, wherein each of the sub-component parts contain change data. The sub-component parts are comprised of a reference that provides a link to one of: another one of the sub-component parts and a position in presentation data. The change data provides information on how to modify a part of presentation data responsive to the associated. The presentation data is assembled using the sub-component parts for a selected set of sub-component parts from the non-transitory memory responsive to said change data and the associated said reference. The presentation is viewed by a user responsive to the presentation data.

  • Patent number: 10387836
    Abstract: A computing appliances for use by a user, provide for collaboration on a common project having an associated base image display. User data representative of a respective display of annotations responsive to user input is stored. The user data is comprised of event content data for respective events that are generated in a defined order of entry relative to other of the events. Presentation assembly logic, selectively retrieves respective said event content data for said events in the selected set responsive to the mapping logic, and generates presentation data responsive to processing the event content data for said events in the selected set, in a respective defined order of entry relative to other of the events.

  • Patent number: 7343619
    Abstract: The objective of this invention is to ensure that programs that generate and send data packets are well behaved. This invention discloses a method and system that consist of an end station and a network interface, such that, the network interface is capable of determining the authenticity of the program used by the end station to generate and send data packets. The method is based on using a hidden program that was obfuscated within the program that is used to generate and send data packets from the end station. The hidden program is being updated dynamically and it includes the functionality for generating a pseudo random sequence of security signals. Only the network interface knows how the pseudo random sequence of security signals were generated, and therefore, the network interface is able to check the validity of the pseudo random sequence of security signals, and thereby, verify the authenticity of the programs used to generate and send data packets.

  • Patent number: 6508706
    Abstract: It is a method of communicating amongst a network of networked computing entities to provide feedback to a user representative of a group social behavior comprising and providing a uniform data structure for each said computing entity which defines group social behavior simulation and the data structure comprising interaction rules and initial conditions. The interaction rules are comprised of fixed and variable elements. The initial conditions are comprised of fixed, variable and random elements—modifying the variable elements of the interaction rules and the initial conditions responsive to interaction of the networked computing entities and exhibiting feedback of the group social behavior simulation to the user of at least one of the computing entities.
