1. A system for detecting at least one of a liquid in an area and the liquid exiting the area, the system comprising:
- a first conductor;
a second conductor;
a contact;
a first resistor; and
a second resistor;
wherein;
absent the liquid, no electrical circuit exists between the first conductor and the second conductor;
a first portion of the first conductor and a second portion of the second conductor are positioned along an outer boundary of the area, the first portion is positioned at most a first distance from the second portion;
a third portion of the first conductor and a fourth portion of the second conductor are positioned within the boundary, the third portion is positioned at least as second distance from the fourth portion;
the first distance is less than the second distance;
the contact electrically couples to the first conductor via the first resistor;
the second portion of the second conductor electrically couples to the fourth portion of the second conductor via the second resistor; and
an electrical circuit between the first conductor and the second conductor as measured between the contact and the second conductor indicates at least one of the liquid is positioned within the boundary of the area and the liquid is crossing the boundary so as to exit the area.

Abstract
Systems and methods for detecting a liquid. Detection a liquid may include detecting liquid at a boundary of an area and reporting the presence of the liquid. Reporting liquid at a boundary may prevent leaking of the liquid from the area. Detecting also includes detecting liquid inside the area. The amount of liquid detected inside the boundary may relate to a range of amounts of liquid. The minimum amount of the range may represent the minimum amount of liquid that is permissible in the area prior to taking action to deal with the liquid.
