Abstract

A digital fencing system includes a first lighting fixture that includes a first communication module, and a second lighting fixture that includes a second communication module. The digital fencing system also includes a control device configured to receive first information from the first lighting fixture. The first information is related to a wireless signal transmitted by a mobile entity and received by the first lighting fixture. The control device is further configured to receive second information from the second lighting fixture. The second information is related to the wireless signal transmitted by the mobile entity and received by the second lighting fixture. The control device is also configured to transmit a control message to the mobile entity to control a movement of the mobile entity based on a location of the mobile entity with respected to a permitted area.

First claim

What is claimed is:

1 . A digital fencing system, comprising:
a first lighting fixture comprising a first communication module; a second lighting fixture comprising a second communication module; and a control device configured to:
receive first information from the first lighting fixture, wherein the first information is related to a wireless signal transmitted by a mobile entity and received by the first lighting fixture;
receive second information from the second lighting fixture, wherein the second information is related to the wireless signal transmitted by the mobile entity and received by the second lighting fixture; and
transmit a control message to the mobile entity to control a movement of the mobile entity based on a location of the mobile entity with respected to a permitted area, wherein the location of the mobile entity is determined based on at least the first information and the second information.

2 . The digital fencing system of claim 1 , wherein the first information indicates a first power level of the wireless signal at a reception of the wireless signal by the first lighting fixture and wherein the second information indicates a second power level of the wireless signal at a reception of the wireless signal by the second lighting fixture.

3 . The digital fencing system of claim 2 , wherein the first information indicates a power level of the wireless signal at transmission by the mobile entity.

4 . The digital fencing system of claim 1 , wherein the first information indicates a first time of arrival of the wireless signal at the first lighting fixture and wherein the second information indicates a second time of arrival of the wireless signal at the second lighting fixture.

5 . The digital fencing system of claim 4 , wherein the first information indicates a time of transmission of the wireless signal by the mobile entity.

6 . The digital fencing system of claim 1 , wherein a boundary of the permitted area is defined based on distances from the first lighting fixture and the second lighting fixture.

7 . The digital fencing system of claim 1 , wherein the mobile entity is a robotic lawn mower and wherein the first lighting fixture and the second lighting fixture are outdoor lighting fixtures.

8 . The digital fencing system of claim 1 , wherein the mobile entity is a robotic vacuum cleaner and wherein the first lighting fixture and the second lighting fixture are outdoor lighting fixtures.

9 . The digital fencing system of claim 1 , wherein the control message includes an instruction to the mobile entity to power off.

10 . The digital fencing system of claim 1 , wherein the control device is configured to transmit the control message to the mobile entity in response to determining that the mobile entity is outside the permitted area.

11 . The digital fencing system of claim 1 , wherein the control device is configured to stop transmitting the control message to the mobile entity in response to determining that the mobile entity is in the permitted area.

12 . A non-transitory computer-readable medium of a controller, wherein the non-transitory computer-readable medium contains instructions executable by a processor, the instructions comprising:
receiving first information from a first lighting fixture, wherein the first information is related to a wireless signal transmitted by a mobile entity and received by the first lighting fixture; receiving second information from a second lighting fixture, wherein the second information is related to the wireless signal transmitted by the mobile entity and received by the second lighting fixture; and transmitting, via a transmitter, a control message to the mobile entity to control a movement of the mobile entity based on a location of the mobile entity with respected to a permitted area, wherein the location of the mobile entity is determined based on at least the first information and the second information.

13 . The non-transitory computer-readable medium of claim 12 , wherein the instructions comprise determining the location of the mobile entity with respected to the permitted area based on at least the first information and the second information.

14 . The non-transitory computer-readable medium of claim 12 , wherein a boundary of the permitted area is defined based on distances from the first lighting fixture and the second lighting fixture.

15 . The non-transitory computer-readable medium of claim 12 , wherein the first information indicates a first power level of the wireless signal at a reception of the wireless signal by the first lighting fixture and wherein the second information indicates a second power level of the wireless signal at a reception of the wireless signal by the second lighting fixture.

16 . The non-transitory computer-readable medium of claim 12 , wherein the first information indicates a first time of arrival of the wireless signal at the first lighting fixture and wherein the second information indicates a second time of arrival of the wireless signal at the second lighting fixture.

17 . A digital fencing system, comprising:
a first lighting fixture comprising a first communication module; a second lighting fixture comprising a second communication module; and a control device configured to:
receive a first video or image from the first lighting fixture;
receive a second video or image from the second lighting fixture; and
transmit a control message to a mobile entity to control a movement of the mobile entity based on a location of the mobile entity relative to a permitted area, wherein the location of the mobile entity is determined based on at least the first video or image and the second video or image.

18 . The digital fencing system of claim 17 , wherein the control device is configured to process the first video or image and the second video or image to identify the mobile entity and an area in the first video or image and in the second video or image and to determine the location of the mobile entity relative to the area.

19 . The digital fencing system of claim 17 , wherein the control device includes information indicating whether the mobile entity is allowed to be in the permitted.

20 . The digital fencing system of claim 17 , wherein the control device is configured to transmit the control message to the mobile entity via the first lighting fixture.
