An apparatus and method for self-initiated instruction issuing are implemented. The synchronization module comprises a program module for generating a synchronization message to be sent and for providing the synchronization message with a first time stamp, and a hardware-implemented time stamp module which receives synchronization messages from the program module and forwards them in accordance with the PTP protocol. In the proposed solution, status information of each non-selected computer is transmitted from the corresponding central unit to the switch. In response to determining that the first data fragment is one of a plurality of data fragments that comprise the first data object, the first data fragment is stored in a memory. By use of the photo-functional particles and powder, an organic polymer composition, a slurry, a coating agent, and a product having a surface exhibiting photocatalytic property and hydrophilicity are obtained. The tesla coil security system includes a tesla coil, a length of wire electrically connected to the tesla coil for surrounding an opening to be protected, and a plurality of charge dissipaters electrically extending from the wire for facilitating the discharge of electrical charge thereby creating an electrical visual effect for deterring entry through the opening.
