A micromechanical structure and a corresponding manufacturing method are described. The bolt is pivotal between a locking configuration where the bolt extends outward of the housing to engage in an aperture associated with a door within the frame and an unlocked configuration where the bolt is withdrawn to clear the aperture. These pad parts are then connected to the semiconductor chips bonding pads through re-distribution layers. All embodiments contemplate selectable removabilty, replace ability and interchangeability. As a result, a card or other such foreign objects can be removed and a monitoring period can be increased until detection of a normal disk is detected. Upon receiving a first Transmission Control Protocol header for a first TCP segment from a network link, the system immediately provides a portion of the first TCP header to a transport layer prior to receiving all payload data for the first TCP segment.
