Abstract: A tray and tray support system which is suited for attachment to a portable folding chair enables the tray mechanism to be either left closely adjacent to the portable seating and unused, or pivoted to a position of deployment. Deployment is effected by causing a tray suspended from a fitting to be pivoted from a vertical hanging position and through an angle of about 270° to then be stably supported at a general horizontal position. The responsibility for pivoting support is divided and uses a pivot stop structure within a tray deployment fitting, and a set of tray supports which are also pivotally attached to the tray deployment fitting about an axis adjacent and parallel to the axis of the main horizontal extent of the main tray bearing member.

Abstract: There is provided, a method of diagnosing a disease state in a subject comprising: (a) obtaining nuclear magnetic resonance data on an obtained biological sample from the subject; (b) performing a statistical analysis on the nuclear magnetic resonance data; (c) determining a subject profile for the biological sample based on the statistical analysis; (d) comparing the subject profile to a predetermined profile for differentiating between: (i) the disease state and a non-diseased state; (ii) a first disease state and a second disease state, or (iii) the first disease state, the second disease state, and the non-diseased state, to provide a diagnosis of the disease state, wherein the comparing does not comprise identification of components of the biological sample.

Abstract: A folding chair includes a canopy which is stabilized in a front to back longitudinal direction using stiff segments which can be folded laterally, and a canopy supported from a pivoting back support with a bracket support which is preferably a multi-detent bracket support which can angularly adjust, upon manual movement by the user to react to changing light conditions. The user can pull the canopy to angle down to block light and wind, or the user can push the canopy to angle up to form a more open appearance while still receiving some benefits from the canopy.
