A respiratory support device includes a ventilator which allows spontaneous breathing, a control device, a dosing device for pharmaceutically active substances, and at least one first measuring device. The security module performs encryption and decryption algorithms, authentication, and public key processing. First and second device engagement tabs engage holes on left and right sides of the device, and first and second chassis engagement tabs engage holes on left and right sides of a chassis opening. The actuator is external to the control circuit frame and has a second terminal coupleable to the first terminal. In a particular embodiment, the forwarding data may include a bit mask. The sequence of views can provide smooth flyovers over positions and details on objects that are deemed to be of interest, with changes in zoom level andor velocity that are functions of the estimated complexity andor unfamiliarity with features of the object.
