Various embodiments provide a so-called companion experience in which content consumed on a primary screen can serve as a source for an automatic search that returns related content that can be presented on an auxiliary screen. The housing has an inwardly extending sidewall to define an accelerating airflow passage between the sidewall, the hub and the rotor blades for effectively increasing the airflow pressure and stabilizing the discharged airflow. The belt may be used to rotate the shaft. A first and a second capacitive element are connected to the gate and drain of the first transistor. Examination of a back surface opposite the front surface allows viewing of the identification indicia for authenticating the secure image.
