The invention is intended to simplify a default mechanism of a throttle valve opening and closing device for the purpose of improving mountability of the device to a vehicle. A request for a Web hosting resource is received by the cloud service, wherein the request is provided by a client. A safety shield is telescoped relative to the hub and the needle cannula and can be moved from a first position where the needle cannula is exposed to a second position where the needle cannula is safely shielded. without substantially increasing molecular bonding between the bonding surface of the interface layer and the bonding surface of the other of the support substrate or the useful layer, so that the separable bonding interface maintains a sufficiently weak bond that can later be overcome by applying stresses to detach the useful layer from the donor substrate. Based on results of the comparison, the server selectively issues a database commit command to make all database updates performed since a last database commit operation a permanent part of the database.
