In the early 90's I worked for Invision Technologies, who built the CTX-5000, an explosive detection device using a CT scanner. It was the first such device certified by the FAA for airport security. In looking at a video of the machine from Analogic, the CT images produced by their machine basically look like what the CTX-5000 produced back in the 90's. The CTX-5000 produced color images in 3D. Nothing new here that I can see.

Never, ever give an exit interview!!! Why? Because an exit interview is used by your company for legal purposes. Maybe you said in the exit interview that you had no concerns, and no negative things to say. And remember the HR representative is probably taking notes, and they may have a questionnaire for you to fill out. But then in the future maybe you decide to sue them for some reason. They'll pull out your statements from the exit interview as evidence that you have no reason to sue them. And yes, they do keep your exit interview records on file. Your own words would be used against you. Also, HR cannot withhold your final paycheck if you don't do the exit interview. That's the law!! I heard this on an NPR show about 15 years ago. The guest for the show was a woman who decided to do research on how HR departments work. While doing the research, she somehow got invited to a conference for HR professionals, where the presenter for the conference stated "It's Us against Them"!!!! Us is the HR department, which is there to protect the company!!! Them is you, the employee!!!! Don't drink the koolaid!!! Remember, HR is there to protect the company, not you.
