A vehicle comprises a body structure defining a window opening, a curtain airbag for the window opening, and a magnetic retention assembly for retaining the curtain airbag to the body structure upon its deployment. The first and second frame components are constructed to permit arrangement of the first and second frame components in an assembled state and a nested state with respect to one another. Accordingly, the external update function data can be downloaded to the household device through the network to update the function of the household device without expense of human resources, even if the household device operates abnormally. A stabilizing surface of the stabilizer is coupled to a drive system to position the surface from outside the patient, preferably by actuators of the robotic servomechanism. The invention utilizes a two-part algorithm to reduce and compress the number of data points representing the ink data. An electrode set adapted to be incorporated into the package can have an aspect ratio in a range of 3.
