Said seamless internal channel from proximal end to distal end eliminates the need for seals commonly found on prior art smoke evacuation pencils having multi-seamed smoke evacuation channel components.

Abstract: A system including a processor may filter a population to identify a group having members, and deliver, over an electronic network, a survey to members of the group to determine value preferences and value gaps. The survey may be made according to a set of paired comparisons or other related techniques. The system may generate vectors according to the determined value preferences and value gaps for members of the group, which may have lengths equal to numbers of determined values for the members. The system may cluster members of the group into segments by calculating patterns of differences between generated vectors. Results of this process enable the creation of a predictive model to estimate segment membership, which can be used in the generation of a promotion for display corresponding to a clustered segment, and deliver the promotion to a client device associated for display.

Abstract: A novel invention squeegee cleans in a first direction, manually or by robot, the inner surface of a bore referred to as a hollow-shape, comprising a longitudinal shaft with a distal end squeegee element, and a cooperatively aligned sheath. Said squeegee element is comprised of shape conforming flexible disks in combination with shape conforming flexible tabbed fins having incrementally sized surface openings to form an ascending or descending path to incrementally collect contaminants. From said first direction the invention exits said hollow-shape distal end, cleaning said inner surface. Said sheath is selectively moved from a first proximal position to a second distal position covering said squeegee element and isolating collected contaminants. A second opposite direction retracts said invention from said hollow-shape, with manual or robotic means, by removing said isolated contaminants preventing recontamination of said inner surface.
