The invention describes DNA molecules which code for plant proteins having the biological activity of a debranching enzyme. The hair braider has a substantially figure 8-configured cam track allowing three carriers to move along the cam track for a 8 track motion. In various embodiments, the memory controller may be further configured to generate a side channel from n-m non-failed die and the m failed die other than a first failed die. If an attachment is detected, some or all of the bits of the data packets associated with the attachment are altered, thereby rendering the infected attachment harmless. According to another embodiment, the power supply system includes a power source providing an output voltage for operating components of the control system, a detector monitoring the output voltage, and a switch for electrically disconnecting the power source from the components of the control system if the output voltage drops below a predetermined level.
