The present invention has for its purpose to provide a technique capable of reducing planar dimension of the semiconductor device. The height-adjustable tabletop ergonomically enhances the surrounding area to accommodate the needs of various users, and an optional sectional heat transfer dome lowers shipping and packaging costs and reduces storage space. The child resistant latch mechanism includes a latch projecting from the flip-top lid and engaging a projection of the closure body. The positioning arrangement is adapted to be fixated by means of an adhesive for fixation of the bite-block such that the head of a patient can be immobilized relative said adaptor unit or frame. The display of the icon may indicate, to the user, whether a device, associated with the icon, is in an energy-saving mode. In one example using inband management information, the method includes encapsulating management information in an internet protocol packet and encapsulating the IP packet in an Ethernet frame.
