Abstract: An online school provides video courses to students that are made up of an unordered group of video segments. The path sequence and quantity of the video segments from the group displayed to each student may be different and are determined by various factors including the student's previous knowledge, style of learning and course criteria.

Abstract: A method is disclosed for determining a location of a mobile electronic device. The mobile electronic device receives an RF signal providing RF fingerprint data and receives a third party location estimate from a third party service. Location data is collected by a dead reckoning system and corresponds to RF fingerprint data and third party estimates collected for a plurality of locations. A correlation between the RF fingerprint data, the third party location estimates, and location data is determined providing a transform for transforming the third party location estimates into a more accurate location estimate of the mobile electronic device.

Abstract: A method of configuring and reconfiguring a computer system based on user authorization is presented wherein at least some users perceive themselves and available system resources as the entirety of the computer system. The resources are configured through use of virtual resources providing predetermined access privileges and configurations for some users. In another aspect, a method is provided of configuring and reconfiguring a computer system based on biometric user input wherein at least some user biometric input is necessary in order to gain authorized access to a system and to configure the system based on the authorized user. The configuration is, preferably, transparent to the user.
