Abstract

Methods, systems and apparatus for detecting object location and generating alerts are disclosed herein. An example disclosed method includes determining an assigned area for an object being handled by a loader; detecting a first location of the loader; determining whether the first location corresponds to the assigned area for the object; and in response to the first location not corresponding to the assigned area for the object, generating a first output indicative of a difference between the first location and the assigned area for the object.

First claim

What is claimed is:

1. A system comprising:
transmitters mounted within a container, wherein each one of the transmitters includes a directional antenna configured to direct transmissions from the directional antenna inwardly towards a center of the container to diminish a strength of the transmission outside of the container;
a receiver having an assigned container identifier, the receiver configured to:
in response to receiving the transmissions from the transmitters, determine a location of the receiver based on the transmissions;
compare the location of the receiver with the assigned container identifier; and
when the location of the receiver is different than the assigned container identifier, generate an alert.

2. The system of claim 1 , wherein the receiver is a mobile computing device.

3. The system of claim 1 , wherein:
a first subset of the transmitters is mounted at a first elevation within the container;
a second subset of the transmitters is mounted at a second elevation within the container; and
the first elevation is different than the second elevation.

4. The system of claim 1 , wherein a first subset of the transmitters is directed away from an opening of the container.

5. The system of claim 1 , wherein a first subset of the transmitters is mounted on a shelf within the container.

6. The system of claim 1 , wherein each of the transmitters is configured to transmit at a respective power level to diminish the strength of the transmission outside of the container.

7. The system of claim 1 , wherein the generated alert is a buzzer sound.

8. The system of claim 1 , wherein the generated alert is a flashing light.

9. The system of claim 1 , further comprising when the location of the receiver is the same as the assigned container identifier, generate a confirmation output.
