A hybrid PCI_Express fabric system allows LPC bus commands and data to be sent across the PCI_Express fabric from a portable computer to its docking station. The ventilation interface includes a pair of nasal inserts made from flexible, resilient silicone which are oval shaped in cross-section and slightly tapered from a base proximal the ventilation supply to the distal tip end. A method of manufacturing a touch panel can include preparing a substrate and a transparent electrode base, forming a transparent electrode over the transparent electrode base, and forming an electrode material over the transparent electrode base. The abutment means consists of respective abutment surfaces protruding from the case to enable a manual thrust to be exerted on the covering element. The opening of each aperture extends in two different planes such that, if at least a part of the opening is covered in one of the two different planes during inhalation by the patient, a void space is created between the cover and the aperture so as to provide an air flow path through the void space to the at least one aperture.
