Embodiments of the present invention provide methods and systems for allocating multiple tags to multiple requesters in back to back clock cycles. The system comprises two main components: an external controller and an external charging coil assembly that is coupleable thereto. Once disposed in the intervertebral space, the expandable intervertebral implant is actuated and deployed, with the superior member and the inferior member moving apart from one another, seating against the associated intervertebral endplates, and distracting, realigning, andor stabilizing them to a desired degree. The startup circuit includes a body bias circuit connected to a body of the first transistor to provide a voltage differential between the body of the first transistor and a source terminal of the first transistor. The mixer has inputs coupled to the output of the first and second flow sensors. The resin is mixed with the cleaned fiber material prior to the cleaned fiber material being dried in the dryer duct.
