Apparatus and method for the deoxygenation of liquid fuel in the fuel system of an energy conversion device, such as an aircraft gas turbine engine. A membrane filter is disposed in the fuel system and is selected to remove oxygen from the fuel, typically a hydrocarbon, while excluding the fuel. The membrane filter may be permeable or porous to the oxygen and, in a preferred embodiment, is of polytetraflouroethylene. Fuel with dissolved oxygen (typically from air) is flowed in contact with one surface of the membrane filter, and removed oxygen is collected from the opposite surface of the filter. The difference in the partial pressure of oxygen across the membrane filter may be controlled to regulate the driving force for moving oxygen through the membrane. Reduction of the oxygen concentration in jet fuel to less than 10 ppm at liquid space velocities of 100/hr and greater are attained.

Disk spacers in multiple disk drives are shaped to provide a reliable mechanism for loading and unloading magnetic recording heads and a reliable latch when the heads are unloaded. The head load/unload system operates between a stack of latch-profiled spacer ramps sandwiching magnetic hard disks and a stack of lifting arms with contoured tips attached to head/suspension assemblies. The lifting arms and their contoured tips are built as part of the one-piece of the suspension load beams at their inner diameter side perpendicular to the load beam axis, or at their front along the axis. The spacer ramps are precisely machined to a latch profile with a desired rounded edge merging with the disk surface, an inclined slope, a round hump and a rounded recess, so that the contoured tip of a lifting arm can slide onto the slope first, over the hump and then into the recess where the tip is latched. The spacer ramps also serve either in a couple as the separator of any two adjacent disks, or individually as the separator between the top disk clamp and the top surface of the top disk and between the bottom base and the bottom disk. The spacer ramps are self-calibrated vertically with the disk stack. Both coated with diamond like carbon or other hard coatings, the profiled spacer ramps, also coated with lubricants after a hard coating, and contoured tips are reliable in ramp wear control. A single sided limiter from the suspension load beam reduces the torsion to the head flexure tang generated by the lifting force at an inner side lifting arm when the head is unloaded from the disk.

A magnetic recording head for use in a disc drive system including a rotating disc has a slider body and a transducer on the slider body for reading and/or writing data from and/or to the disc. A piezoelectric sensor is provided on the slider body and produces a signal representing a level of interference between the slider body and the rotating disc. A method of predicting a head crash includes establishing a nominal level of interference between the magnetic recording head and the rotating disc and establishing a threshold interference level difference. The level of interference between the magnetic recording head and the rotating disc represented by the signal provided by the piezoelectric sensor is monitored during operation of the disc drive system. A predicted head crash is indicated when the level of interference between the magnetic recording head and the rotating disc is different from the nominal level of interference by more than the threshold.

Various examples are provided for photoacoustic image reconstruction and processing utilizing a backprojection approach. In one example, among others, a method for producing an image with a photoacoustic imaging system includes scanning an object with a plurality of light beams, detecting a plurality of acoustic signals produced by the light beams, and generating a reconstructed image from the plurality of acoustic signals by filtered backprojection (FBP) that utilizes a weighted ramp filter. In another example, a system includes a plurality of acoustic detector units and a processing unit. The acoustic detector units can receive an acoustic wave and convert it to time dependent electrical signals. The processing unit can reconstruct an image of the subject from the time-dependent electrical signals by FBP that utilizes a weighted ramp filter. In another example, non-transitory computer readable medium stores a program that can cause a processing unit to reconstruct an image.

A method for reducing coke deposits includes heating an alcohol-fuel mixture to decompose alcohol and form water to produce a fuel-water mixture and delivering the fuel-water mixture to a carbon-steam gasification catalyst. The fuel-water mixture reacts with the carbon-steam gasification catalyst such that coke deposits are prevented from remaining in a space near the carbon-steam gasification catalyst.
