With a display device in which a main display component is supported in a tilted orientation by a stand unit, the leg of the stand unit will not be pushed in, causing the main display component to readily fall over backwards, even if the main display component in a tilted orientation should be accidentally pushed by hand. The brace includes a bottom surface and a vertical side surface. The index cache includes the files that were stored on the storage medium the last time that the storage medium was coupled to the computing device. Thus, by appropriately using diffracted light of different orders, it becomes possible to perform convergence on optical disks of different wavelengths and base thicknesses, with reduced spherical aberration. Also, the thermally curable solder-resistant ink has good electrical properties, folding endurance, solder resistance, warpage resistance, flame resistance, acid endurance, alkali endurance, good solvent resistance and low water absorption. The system includes an extended PHY device for receiving wake-up signals from a network medium, converting the wake-up signals into an additionally-encoded data packet, and generating a standardized wake-up packet based on the additionally-encoded data packet.
