Abstract: Systems and methods for managing surgical sponges. A dispenser assembly coupled to a main support includes an internal or first storage location to removably receive a carton of sponge sorters, and an external or second storage location to removably support a carton of surgical draping. At least one arm may be supported on the housing and movable between an undeployed position and a deployed position. The arm may include weighing means to measure a weight of the surgical sponge being disposed in a sponge sorter supported by the arm. The arm may be a cantilever and abeam load cell may be disposed within a channel of a beam. A processor may determine fluid weight based on measured weight and dry weight correlated with the surgical sponge being counted out as detected with a data reader. The processor may estimate blood loss to be displayed on a display.

Abstract: A method of managing risk in an investment fund is implemented on a computer based system. The method includes (a) determining a primary investment in accordance with a primary investment objective; (b) determining a secondary investment objective that is a financial opposite of the primary investment objective; (c) determining secondary investment in accordance with the secondary investment objective; (d) performing a rebalancing cycle having (i) at a first point, (1) calculating a net asset value of the investment pair according to formula EQ.NAV=(EQ.primary+EQ.secondary); (2) calculating a nominal net asset value according to formula NN.NAV=(HU.primary*PI.market price+EQ.secondary) (3) calculating an actual leverage factor according to formula LF.actual=(NN.NAV/EQ.NAV); (ii) at a second point calculating by a computer of a rebalance trade of the primary investment according to formula RBTR=(EQ.NAV*LF.target?NN.NAV).
