Abstract: An embodiment provides a method, including: operating a motor to position sample fluid within a fluid channel of a cuvette; transmitting light through an optical chamber of the cuvette; measuring a value of received light that has been transmitted through the optical chamber; comparing the measured value of light to one or more thresholds; determining a position of the sample fluid within the fluid channel based on a comparison from the comparing step; and generating a response based upon the position of the sample fluid with the fluid channel. Other aspects are described and claimed.

Abstract: An embodiment provides a cuvette, including: a body having a fluid channel therein; and an outer surface having encoded information disposed thereon and readable by a reader of a sample instrument. Other aspects are described and claimed.

Abstract: An angled offset tulip has an angled offset tulip with a rod receiving portion and a bone screw receiving portion. The bone screw receiving portion has a distal opening on a distal end. The rod receiving portion is positioned offset a distance from a center of the distal opening and elevated above the distal opening to form an angle ?. The angle ? is defined as a line passing through the center of the distal opening and a slotted end center. The rod receiving portion has a slotted opening defined by a pair of sides, each side having a proximal end with threads for engaging a set screw to secure a rod. The angled offset tulip can be an angled offset tulip assembly having a collet for receiving, holding and fixing the head of a bone screw.

Abstract: A modular head bone screw assembly has a bone screw, a tulip and a saddle. The saddle is positioned in a recess inside of the tulip. The saddle has a proximal end for engaging a rod and a distal end for receiving a hemispherical or at least partial hemispherical head of the bone screw. The saddle is sized to move axially inside the tulip. The saddle has a plurality of fingers separated by slots extending from near the proximal end through the distal end in an initial un-loaded position and upon insertion of the tulip over the head of the bone screw, the saddle moves proximally over the head simultaneously causing the fingers to move past a maximum diameter of the hemispherical head and upon tightening the rod by a set screw, the fingers locking the bone screw into the tulip.
