A flat type wave gear device is realized having a much improved load capacity. The panels each have an end edge that cooperate to define an imaginary plane at one end of the sleeve. The private modules are accessible to users with valid login credentials or those authenticated via a related entity, such as a Live ID. The controller is further configured to set a first storage region for writing data sent from the computer to a second storage region. One method includes directing light to the edge of the specimen at an oblique angle of incidence.
