Abstract: Methods, systems, and apparatus for providing customizable interaction with a mobile terminal using external input devices are provided. A first activation signal that corresponds to a first function in the mobile terminal is received into the mobile terminal from a first external input device of the plurality of input devices that is configured to receive a first activating input from a user. The first function is activated in the mobile terminal responsive to receiving the first activation signal. A second activation signal is received into the mobile terminal from a second external input device of the plurality of external input devices that is configured to receive a second activating input from the user. The second activation signal corresponds to a second function in the mobile terminal. The second function is activated in the mobile terminal responsive to receiving the second activation signal.

Abstract: A fixation device for holding a medical instrument such as a trocar, on the skin of a patient in relation to surgery. An attachment device is provided for releasable fixation of the device on a patient and having an aperture through which the instrument may be received. A retention device is provided for frictionally engaging the instrument in the fixation device in a predetermined position; wherein the attachment device includes a flexible sheet-like member and the aperture is provided with an associated instrument receiving slot in the attachment device for radial insertion of the instrument. Such fixation device is suitable for use in relation to instruments such as trocars having a range of external diameters. The fixation device is advantageous since it is non-invasive. Moreover, the fixation device ensures an airtight seal with the trocar and provides for adjustment of the position of the trocar after the trocar is positioned without having to remove the entire trocar.
