A chuck locking and unlocking assembly includes a chuck key which has a shank with a tapered toothed surface defined in a first end thereof and a connection end is connected to a second end of the shank. The object may alter its behavior from one object type to another at anytime without requiring a new object to be instantiated. In some embodiments, a bridge may couple a dynamic interbody device to a dynamic posterior stabilization system. The fuse bracket, wire connector and the input and output terminals are aligned with corresponding holes in the case so a person can replace the fuse and connect or disconnect wires without removing the PCB from the case. In various embodiments, claims can be processed in accordance with a data-driven approach that limits changes to existing claims processing rules. The transparent sleeve is preferably the lamp sleeve itself, with the secondary, capacitor and any desired starter mechanism disposed within its interior.
