And if you don’t like the main unmount-on-sleep feature, you can disable it-permanently or temporarily-and just use the rest of Jettison’s features.
#JETTISON SOFTWARE MAC#
At any time, you can eject all external volumes without putting your computer to sleep or, if you’ve got a desktop Mac or if you want to keep your laptop’s screen open while it sleeps, you can manually choose to eject volumes and sleep. Jettison’s optional systemwide menu provides a few extra options. You’ll need to either wait for the task to complete or quit the offending application and then try again. If for some reason Jettison can’t unmount a drive-for example, if a utility like SuperDuper is currently backing up to that external drive-Jettison will play an error sound to let you know it was unsuccessful.
In my testing on a 2010 iMac with six external volumes mounted, and on a 2010 MacBook Air with three volumes mounted, putting the computer to sleep with Jettison running takes about 10 seconds. Since JETT is written in JAVA, it is essentially platform-independent.For obvious reasons, Jettison prolongs the sleep process to give the utility time to ensure all drives are unmounted (and to play the confirmation sound). The JETT utilizes orbital mechanics with complex algorithms. The controller category allows for handling events that affect the model or view(s). The view category provides capabilities for data entry and displaying all or a portion of the analysis data in tabular, 2D, and 3D representation. The model category is for maintaining data entered by the user and generated by the analysis.
#JETTISON SOFTWARE CODE#
The code makes extensive use of the object-oriented format of Java and, in addition, the Model-View-Controller architecture was used in the organization of the code, allowing each piece to be independent of updates to the other pieces. The developers followed the SMP to create the code and all supporting documentation. It provides the ability to define the jettison operation relative to International Space Station (ISS) structure, and provides 2D and 3D plotting capability to allow an analyst to perform a subjective clearance assessment with ISS structures.

The software will reduce the jettison analysis task from one that could take days to complete to one that can be completed in hours, with an analysis that is more comprehensive than the previous method. This supports the analysis that jettisoned items will safely clear the vehicle, ensuring no collisions.
The main concern is the interaction and possible recontact of the jettisoned object with an asset. It provides a method to compute the relative trajectories between an orbiting asset and any jettisoned item (intentional or unintentional) or sublimating particles generated by fluid dumps to assess whether an object is safe to jettison, or if there is a risk with an item that was inadvertently lost overboard. Jettison engineering trajectory tool The Jettison Engineering Trajectory Tool (JETT) performs the jettison analysis function for any orbiting asset.
