The present invention is a fistula sleeve for covering and protecting a fistula on the inside of an arm. The sleeve grips the wrist and adjustably and snuggly fits around the wider contours of the arm without imparting pressure on the fistula. The sleeve partially opens to expose the fistula for dialysis and daily care. A narrower wrist region secures around the wrist. An elongated forearm region wraps around the forearm, and a smooth central region covers the fistula. The wrist and forearm regions are independently secured. Securement strips have semi-rigid backings that stiffen the side portions of the sleeve help secure and remove the sleeve with one hand, and form a spine to help maintain the alignment of the sleeve on the arm. A double layer of material is stitched together along its perimeter, while the inner layer is free to slide relative to the outer layer in the smooth central area that engages the fistula. The sleeve stretches laterally to grip and secure around the wrist, while allowing the forearm portion to snuggly fit around the contours of the forearm and accommodate the fistula in a non-pressure generating manner.

A system and method is provided that employs schedules and gains in an electronic control unit for a gas turbine engine which are independent of fuel type used to run the engine. According to one embodiment, the method comprises the steps of determining engine requirements and calculating a desired energy flow for at least one engine, maintaining desired engine conditions according to the desired energy flow; converting the desired energy flow into expected fuel flow according to the specific fuel being utilized, calculating a fuel flow command, and communicating the fuel flow command to at least one fuel valve.

Energy based fuel control system for gas turbine engines running on multiple fuel types

A control and method for arresting flashback in a gas turbine engine combustion system having a venturi for delivering a mixture of air and fuel to a combustion chamber and a valve for controlling the amount of air flowing to the venturi. The control and method includes a flashback detection routine, a valve position trim routine, and a reference flame temperature adjustment routine. The flashback detection routine detects a flashback in the venturi by comparing the temperature at the venturi to the temperature of the air entering the valve. The valve position trim routine receives this flashback signal and in response causes the valve to open until the flashback is arrested. Finally, to prevent the flashback from recurring, the reference flame temperature adjustment routine adjusts a reference flame temperature in the control system so as to prevent the valve from returning to the position at which the flashback occurred.
