Method and apparatus for printing onto a rotating media is described. According to one embodiment, the printing system includes a print head that is laterally displaced from a radial printing radius, a rotating mechanism to rotate the media, and a controller to print onto an annular print area. The annular print area is defined by an inner hub circumference, two lines substantially parallel to the radial printing radius and tangential to the inner hub circumference, and an outer edge of the media. The print head moves about the annular print area by one or more motion mechanism and prints images onto the media.

Disclosed are apparatus and methods for implementing a radial sled printer device that substantially simplifies the complexity and reduces system costs and size for radial printing devices, both for devices that print and those that also record and print a label on circular media. In an embodiment, a print head is radially mounted in a substantially fixed position over a platter such that said platter moves as a sled under the print head for dispensing ink object along a radius or a line parallel to a radius as the media spins, effecting labeling of the media. In an alternate embodiment, a print head is radially mounted in a fixed position over an optical recording drive such that said drive moves as a sled under the print head for dispensing ink object along a radius as the media spins, affecting recording and labeling the media in a single insertion of the media.

Methods and apparatus for determining angular position information and the printing of individual ink objects at target print sectors disbursed around an annular surface on a circular spinning media such as on a CD, dynamically during the radial printing process, are described. Mechanisms for computing the instantaneous angular position and apparatus for collocating encoder devices in close proximity to the CD rotation motor are disclosed.

Methods and apparatus for interleaved printing of individual ink objects at target print sectors disbursed around an annular surface on a circular spinning media such as on a CD, dynamically during the radial printing process, are described. Mechanisms for interleaving printing during the radial printing process, enabling the use of commercially available ink jet pens for radial printing directly on CD devices at greater than 2× rotation speeds, and thus reducing pen limitations in firing frequency and recovery time, are disclosed.

Disclosed are apparatus and methods for implementing polar halftone techniques that substantially reduce or eliminate interference patterns while printing on rotating circular media with a radial print system. In one embodiment, Cartesian image pixels are selected such that screen pixels or “dots” are arranged fan-shaped along radii (or “spokes”) and in annular ring segments (or “arcs”). Halftone sampling frequency may be varied along spokes and arcs or along a polynomial curve relative to the center of spinning media, in order to reduce distortion and artifacts.

A tube and float system for use in separation and axial expansion of the buffy coat includes a transparent or semi-transparent, flexible sample tube and a rigid separator float having a specific gravity intermediate that of red blood cells and plasma. The float includes a main body portion of reduced diameter to provide a clearance gap between the inner wall of the sample tube and the float. One or more protrusions on the main body portion serve to support the flexible tube. During centrifugation, the centrifugal force causes the diameter of the flexible tube to expand and permit density-based axial movement of the float in the tube. The float further includes a pressure relief system to alleviate pressure build up in the trapped red blood cell blood fraction below the float, thereby preventing red blood cells from being forced into the annular gap containing the buffy coat layers.

The invention provides a steering column assembly for supporting a steering wheel in a vehicle. The steering column assembly includes a steering column having a first end and a longitudinal axis. The steering column assembly is disposable in the vehicle for raking movement about the first end and for collapsing movement along the longitudinal axis. The steering column assembly also includes a collar engaged with the steering column to move with the steering column at least during the raking movement. The steering column assembly also includes a support bracket for supporting at least one gage of the vehicle. The support bracket is releasibly engaged with the collar such that the support bracket separates from the collar in response to the collapsing movement.

A hold down assembly for use in a tubular container transport apparatus comprises upper and lower pieces movably mounted relative to one another. Preferably the lower piece is removably seated on a mounting plate of the transport apparatus and the upper piece is adapted to magnetically interact with a tube holder carrying a filled tube product, such that the tube holder may be retained in registered alignment relative to an ejector rod during ejection of the filled tube product. A tubular container transport apparatus and a methodology for ejecting a filled tube product with a reduced risk of dislodgement are also provided.
