Abstract: Cradle assemblies for supporting a door for uninstalling and/or installing the door to a fuselage of an aircraft, and arrangements and methods for the same are provided. In one example, a cradle assembly includes a first contoured board and a second contoured board that is spaced apart from the first contoured board. The first and second contoured boards are cooperatively configured to support outer sections of a first door. A third contoured board is configured to be selectively positioned adjacent to and extending higher than the first contoured board to support a first outer section of a second door that has a different outer shape than the first door. The third contoured board is contoured to substantially match the first outer section of the second door. The cradle assembly is configured to be positioned proximate to the fuselage.

Abstract: An injector clamp for clamping at least two injectors to an engine head includes a body having at least a first arm and a second arm. Each arm having a first clamping surface and a second clamping surface on opposing sides of the body. A distance between the first clamping surfaces of the first arm and the second arm is different from a distance between the second clamping surfaces of the first arm and the second arm. The body is configurable, for use, in one of: a first position in which the first clamping surfaces from each of the first and second arms can abut with an injector; and a second position in which the second clamping surfaces from each of the first and second arms can abut with an injector.

Abstract: A method and apparatus for measuring the beam current of a particle beam in an accelerator by charging the capacitor across an operational amplifier and controlling the scaling of the amplifier output with a programmable gain amplifier (PGA). The out put of the (PGA) is sampled and storing with an analog-to-digital converter to acquire and store at least two digital voltage values. The two digital voltage values are using to obtain a value proportional to beam current. A field programmable gate array is used to implement digital logic to sample and hold output from the analog-to-digital converter.
