Filed:

Apr 12, 2008

Appl. No.:

12/101984

Inventors:

Nathan Calvert - Austin TX, US

International Classification:

G09B 7/00
G09B 5/08

US Classification:

434350, 709204

Abstract:

Learning management systems and methods are provided with improvements allowing meta-tagging of learning objects with specific characteristics. An intelligent tutor application may employ the tags in search and tutorial scenarios. In some embodiments, an intelligent tutor application is programmed for selecting and providing learning objects for presentation to a participant through the participant client application, the intelligent tutor application including a software interface adapter for sending software interface function commands associated with the conformant learning object on behalf of the participant, the intelligent tutor application further including a search and selection software module, a learning style analysis software module, and a tutoring engine software module. In some embodiments, an intelligent tutor interacts with a SCORM-compliant LMS through a modified API adapater.

International Classification:

G06F 15/16

US Classification:

709248

Abstract:

Mobile synchronization systems are provided for synchronizing user data objects among user devices. In one embodiment, mobile devices are provided with a synchronized environment to a user desktop, having either synchronized copies of the data objects, or a shortcut to a system peer storing the data object. Another embodiment provides priority scoring of data objects to keep the most desired objects locally on mobile devices. Another embodiment provides separate handling and prioritization for user media files. Preferably, synchronization is always-on and user transparent.

International Classification:

H04N 7/14

US Classification:

348 1402, 348E07078

Abstract:

Videophone systems and methods are provided, both for construction and use of videophones, as well as configuration thereof. A preferred system allows remote users to configure dialing options for a videophone user who may not have PC operation skills or access. A user receives their unit, connects it to the internet or network, and stored configuration data is automatically downloaded for presentation in a menu structure. Remote users may also upload multimedia data such as pictures for automatic download and display by the unit in a format such as a “digital picture frame” feature. A preferred videophone uses a television set for display and a universal remote to control both the television set and the videophone. The remote may have a microphone for receiving the audio portion of videophone calls, and for receiving audio for speech-to-text control of directory or internet search.

Abstract:

A peer-to-peer wireless phone system with peer-to-peer units and network configuration algorithms by which a virtual circuit data path is established by minimizing the latency added at each hop starting with the external network gateway or the most loaded hop and choosing closest time slots for each next hop until a the virtual circuit is completed. Also, certain embodiments of the present invention include network configuration algorithms by which traffic around any external network gateway(s) is optimized to maximize throughput around the gateway by allocating certain of many available channels to a group of P2P units around the gateway, these units acting as an “infrastructure” through which other units route virtual circuits through the gateway. The network topology is also configured to let these units transmit at higher power levels and ranges than other P2P units in the network, and thereby help minimize the number of hops needed to reach the external network gateway. Further, other sets of units can be configured with similar larger transmit ranges (around 4 of the standard P2P hop ranges), positioned at such a range on the opposite side of from the gateway to also act as “infrastructure units”, both to pass calls forward to the group of units in the gateway's Point Coordinator group, and to also route circuits that are internal to the network around the Point Coordinator group on the gateway, thereby maximizing efficient use of the gateway capacity. Such rings or layers of infrastructure can be repeated as necessary to minimize hops as the network grows larger, making the tradeoff between minimizing hops (which maximizes transmit power and increases co-channel interference) and minimizing power (which maximizes the number of hops and produces poor latency).
