Abstract: Described herein is a method and platform for conducting a buying campaign of a cohort of a plurality of buyers and suppliers. An online platform enables engagement, collaboration and sharing with buyers and suppliers. A lead moderator orchestrates the buying campaign. Preference parameters and nano segments are created. A nano segment is a small group of consumers with a multiplicity of matching profile demographic and background criteria. A buying campaign can be split into sub campaigns with additional moderators supporting the campaign moderator. The buyers co-create the specific products and services along with the suppliers in order to create a highly tailored experience for the nano segment involved. AI algorithms augment the experience by providing product, add ons, and participant recommendations to the moderator and buyers.

Abstract: A C-arm x-ray machine includes a compact yoke and a support arm interposed between the yoke and the support base to reduce overall length of the machine and to increase overscan. The support arm is designed to lower the axis of rotation such that the axis of rotation nearly coincides with the center of gravity of the C-arm. The compact yoke is designed with a thin pivot point and includes a steel sleeve to enclose a pin situated at the first end of the yoke. The steel sleeve is required to strengthen the yoke at the critical load bearing area near the first end of the yoke.

Abstract: A support arm for use with a C-arm x-ray imaging machine is interposed between the yoke and the cross member of a C-arm x-ray imaging machine. The support arm is a generally rectangular structure having a first end, a second end and a central area between the first end and the second end, a generally circular pin attached to or integrally molded with the first end of the rectangular structure, said pin being set at an obtuse angle relative to the vertical, and a generally circular aperture defined within the second end of the rectangular structure. The support arm also includes a plurality of weight reducing apertures, or pockets, are defined within the support arm and the weight reducing pockets are covered with a plate to prevent contamination. The support arm reduces the overall length of the x-ray apparatus, brings the axis of rotation of the C-arm closer to the center of gravity and saves weight.
