1. A method of controlling a process to prevent injury, the method comprising:
obtaining a location estimation of a mobile transmitter affixed to an object, wherein the location estimation is relative to a location of a fixed receiver, and wherein the obtaining the location estimation comprises sending an ultra wideband communication from the mobile transmitter to the fixed receiver and acquiring the ultra wideband communication by a phased antenna array of the fixed receiver;
assessing, based on the location estimation, that the mobile transmitter is within an impermissible location;
determining that the location estimation is sufficiently accurate based on a distance between the location estimation and the fixed receiver; and
interrupting the process upon both the assessing that the mobile transmitter is within an impermissible location and the determining that the location estimation is sufficiently accurate.
