There's often a trend in speculative fiction to invent names for things which pretty much describe their function - case in point: restraining bolts. They are bolts that restrain droids. This is an easy way of naming things, but it does mean that characters can often figure out what something does just by learning the name.
In the real world this is not always the case. Take for example... (looking around)... Google Chromecast. If you didn't already know what this gadget does, you'd have no way whatsoever of figuring it out just from the name (without looking it up online, I mean).
So in your games, consider naming gadgets with less descriptive words. Instead of calling something a "proximity triggered anthrax deployment intruder deterrent unit", call it a "Fluffy Bunny brand WelcomeFlower(TM)" or something.
