Certain implementations of the disclosed technology include systems and methods for determining a reachability score of a phone number. A first contact member can extend from the base laterally adjacent to the first crimping structure. While one surface of the first substrate is disposed close to a deposition target surface of a second substrate, the first substrate is irradiated with light from the other surface of the first substrate. Two or more of such safety controllers are connected through their connecting output parts and the connecting input parts to together form a safety system. The packet engine can also process data packet fragments by assembling the fragments prior to transmitting them to the selected core, or by transmitting the data packet fragments to the selected core.
