Abstract: A system is described for ordering oligonucleotides through a network, such as the Internet. The system provides a mechanism for validating the data provided by a customer, and then displaying graphical images to represent any data that has errors. The system can also pool multiple oligonucleotide samples together by providing graphical images representing oligonucleotide containers, and allowing the customer to select the proper containers to pool.

Abstract: A power transmitting assembly includes a first rotatable assembly, a second rotatable assembly having an axially movable rotating member, a camming assembly for moving the rotating member and an electromagnetic clutch for activating the camming assembly. The rotating member is moved between a first position where the first rotatable assembly operatively engages the second rotatable assembly and a second position where the first rotatable assembly is disengaged from the second rotatable assembly. The power transmitting assembly is shown in three forms--a locking hub assembly, a lockable differential assembly and axle assembly having an axle disconnect.
