Figures from Blackboard's Patent |
Blackboard's patent (US Patent 6,988,138, Alcorn et al Jan 17, 2006) is online at patft.uspto.gov but the figures are hard to get at there. I wanted to read the patent, so I downloaded and organised all the figures. Here they are as a shared resource if you also want to read it.
