The in-line hand operated valve controls the flow of at least the irrigation fluid or suction to a surgical site. Embodiments of the invention may be applied to provide a more uniform temperature profile when processing 300 mm and larger wafers having different curvature profiles that occur at the same andor different points in a manufacturing cycle. The device ensures the moving masses to be reliably decelerated. The passenger may send e-mail communications by composing a message on the passenger computing device and sending it via the web-based proxy server.
