Filed:

Nov 19, 2012

Appl. No.:

13/681137

Inventors:

BARR ROSENBERG - The Sea Ranch CA, US
Mark Gilbeau Howard - Orinda CA, US
Till Gaston Balz Bay - Zurich, CH
Bernd Kurt Alexander Schoeller - Zurich, CH

International Classification:

G06F 17/30

US Classification:

707756, 707798

Abstract:

A data structure for storing items of information having a time of life includes a time of life interval for each item of information, and methods for using the same. The items of information are organized in a data structure having nodes and edges connecting the nodes. This data structure is preferably a directed acyclic graph structure. The data structure includes parent nodes and child nodes. The time of life interval specified for any child node generally is contained within the time interval specified for that child node's parent node, such that the data structure includes no child nodes with a time of life interval that falls outside of the time of life interval of its parent node.

US Classification:

707755, 707716, 707797

Abstract:

A data structure for storing items of information having a time of life includes a time of life interval for each item of information. The items of information are organized in a data structure having nodes and edges connecting the nodes. This data structure is preferably a directed acyclic graph structure. The data structure includes parent nodes and child nodes. The time interval specified for any child node must always be contained within the time interval specified for that child node's parent node, such that the data structure includes no child nodes with a time of life interval that falls outside of the time of life interval of its parent node.

Barr ROSENBERG - The Sea Ranch CA, US

International Classification:

G06F 3/0483
G09B 7/00
G06F 3/0482

Abstract:

An interactive graphical user interface for navigating an electronic textbook includes nodes and connectors connecting the nodes. The nodes may correspond to items of educational content, and the connectors may correspond to a plurality of paths through the nodes. As a user navigates through the electronic textbook, the user may be presented with a custom map of the electronic textbook. A path of traversal may be permanently stored.

Barr ROSENBERG - The Sea Ranch CA, US

International Classification:

G09B 5/06
G09B 5/02
G09B 7/08
G09B 19/00

Abstract:

An electronic publication environment includes nodes containing items of educational content, and a plurality of paths through the nodes. Each path represents a different organization of the nodes in the electronic textbook. The paths are tailored to the educational needs of the users of the electronic textbook. As a user traverses the nodes of the electronic textbook, the user creates a personalized path. The user can add comments to the nodes and connections of this path. These paths and associated comments are made available to other users of the electronic textbook.

Bernd Kurt Alexander Schoeller - London, GB

International Classification:

G06F 17/30

Abstract:

A data structure for storing items of information having a time of validity includes a validity interval for each item of information, and methods for making and using the same. The items of information are organized in a data structure having nodes and edges connecting the nodes. This data structure is preferably a directed graph structure that may include cyclical nodes. The data structure includes parent nodes and child nodes. The validity interval specified for any child node generally is contained within the validity interval specified for that child node's parent node, such that the data structure includes no child nodes with a validity interval that falls outside of the validity interval of its parent node.
