If you search the U.S. Patent system, you can find a lot of crazy things, because the patent office never actually verifies them. Take everything you read in patents like this with a grain of salt. One example I've seen is a mind control patent circulated in the conspiracy community. > by displaying special images using Visual Basic, the CRT will emit electromagnetic waves at specific frequencies corresponding to the images. This is real, many side-channel attacks use these techniques, you can even broadcast amplitude-modulated radio. > And if we emit EM waves of a certain frequencies, mind control is achieved. It even has some code! Probably bullshit. Even if it's possible for EM waves to alter the mind, a CRT doesn't work well. But you can say that it's easier to mind control someone using the web page displayed on the CRT, which is technically electromagnetic waves...
