Portable Boundary Sensor System and Method
First Claim
1. A boundary warning device comprising:
- one or more portable motion sensors, each with sensitivity adjustment and wireless transmission capabilities;
said motion sensors positioned in series to form a boundary such that each subsequent sensor is located within the field of view of the previous sensor, and the first sensor is within the field of view of the last sensor,a portable base unit, with wireless receiving and transmission capabilities;
said motion sensors in communication with said base unit; and
a microcontroller in said base unit to analyze information received from said motion sensors, perform object discrimination functions, and trigger a warning when the parameters for sufficient boundary obstruction are met.

Abstract
A method and system that creates a boundary with an alert and deterring function when the boundary is crossed. The system employs a base unit and one or more portable IR motion sensors which are capable of discriminating between objects of differing physical characteristics, and notifies the user when the parameters for sufficient obstruction have been met. Both sensors and base unit have audio and visual deterring capabilities to frighten away unwanted intruders. The method and system can be utilized in camping situations to deter dangerous wildlife and can be configured to notify users when children exit from an area. The system can be used to create a contiguous perimeter, or any boundary arrangement desired.

13. A method for monitoring the breach of a boundary comprising:
-
creating a boundary by positioning one or more motion sensors in series such that each subsequent sensor is located within the field of view of the previous sensor, and the first sensor is within the field of view of the last sensor; setting the sensitivity parameter on each said motion sensor to a user defined level; sending a communication signal from one of said motion sensors, that detects motion, to a base unit when the motion threshold level corresponding to said sensitivity parameter of said motion sensor is exceeded; analyzing the time said motion threshold level is exceeded; emitting a warning signal if said time is greater than a user defined critical value; and identifying which of said motion sensors initiated said warning signal. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for monitoring the breach of a boundary comprising:
-
creating a boundary by positioning one or more motion sensors in series such that each subsequent sensor is located within the field of view of the previous sensor, and the first sensor is within the field of view of the last sensor; setting object discrimination parameters; sending a communication signal from one of said motion sensors, that detects motion, to a base unit when motion is detected; evaluating said communication signal based on said object discrimination parameters to determine an obstruction level; and emitting a warning signal if said obstruction level is greater than a user defined critical value. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)
