US 12,440,991 B2 · Ultra wideband location determination with predicative and power saving capabilities

Abstract

Techniques for controlling a process to prevent injury are presented. The techniques include obtaining a location estimation of a mobile transmitter affixed to an object, where the location estimation is relative to a location of a fixed receiver, and where the obtaining the location estimation includes 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 assessing that the mobile transmitter is within an impermissible location and determining that the location estimation is sufficiently accurate.

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.

A system comprising:

a mobile transmitter configured to be affixed to an object;
and
a fixed receiver comprising a phased antenna array;
wherein the fixed receiver is configured to control a process to prevent injury by performing actions comprising:
obtaining a location estimation of the mobile transmitter, wherein the location estimation is relative to a location of the 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 the 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;
