An apparatus and method used to detect metallized containers or other objects in closed packages traveling in a conveyor stream. The spacing is easily adjustable at the time of manufacture for locking a printhead into a selected distance from the media support. The truck bed extension also has a ramp lip, such that the ramp lip acts as an extension of the ramp and is positioned on the extended tailgate of the truck. The adapted schedule is further modified based on historical information to compensate for historically predicted events that may conflict with events in the adapted schedule. The method for processing data is such that in a method for processing a data body b which is encrypted and is decrypted on a decryption bit length basis, and thereby is reproduced, the data body b is encrypted, a part of this data body b with a bit length different from the decryption bit length is omitted, and the omitted part is closed so as to make the data continuous. In some embodiments, altering the vehicle state is based, at least in part, on a driver position with respect to the one or more objects determined to collide with the vehicle.
