Methods and apparatus to detect and warn proximate entities of interest
First Claim
1. A method for assessing a possibility of a collision between a first entity of interest and a second entity of interest, the method comprising:
- creating a first safety zone around a first entity of interest;
creating a second safety zone around a second entity of interest;
dynamically modifying the first safety zone and the second safety zone based on a first characteristic of movement of the respective first entity of interest and the second entity of interest, wherein the first characteristic of movement being a range of speed;
dynamically modifying the first safety zone and the second safety zone based on a second characteristic of movement of the respective first entity of interest and the second entity of interest, the second characteristic of movement being a direction of travel; and
analyzing the modified first safety zone of the first entity of interest and the modified second safety zone of the second entity of interest for overlap to assess a possibility for a collision between the first entity of interest and second entity of interest.

Abstract
Systems and methods to detect and warn proximate entities of interest are described herein. An example method for assessing a possibility of a collision between entities of interest, each having their own characteristics of movement, includes sampling movement of each entity at least two points in time, generating a trajectory vector for each entity based on the movement sampling, expanding the trajectory vector of each entity based on at least one characteristic of movement of that entity, and analyzing the expanded trajectory vector of each entity for overlap to assess a possibility of a collision between the entities of interest.
