Abstract: A system for sorting dunnage of an article array having a programmable robot including an arm for transferring a dunnage from a stack of dunnage of different types to a collection area. The programmable robot includes a head having a first griper assembly for engaging with a first type of dunnage, a second clamping griper for engaging with a second type of dunnage; and a third gripper assembly for engaging with a third type of dunnage. The first griper assembly, the second griper assembly and the third gripper assembly are independently operated and configured to engage the respective dunnage based on the type of dunnage.

Abstract: A web application facilitates live on-line academic competition between teams and individuals based on multiple choice or fill-in-the-blank questions and fosters academic competition between students and schools. Using the software application, a team's Coach may enter his/her team in a league of regular competition, schedule a single competition with another team, or organize a competition between the team's members by dividing the team into multiple teams. The test environment provides the experience of competing over test questions, including a scoreboard that keeps track of progress with respect to the test time and the opponent. Students of comparable abilities on competing teams are matched using a matching algorithm that matches the students based on past test performance and the like.
