Abstract

Claims (41)

1 . A system for determining occupancy within a space, the system comprising:

at least one processor; and

memory storing instructions executable by the at least one processor, the instructions when executed cause the system to:

obtain information related to presence of a user within a space;

obtain information related to one or more RF signals within the space;

associate the one or more RF signals with the user based on the information related to presence of the user and information related to the one or more RF signals, the one or more RF signals including RF signals emitted by one or more user devices;

assign a weight factor to the RF signals based on a type of the user device emitting the RF signals; and

determine presence of the user based on association of the user with the one or more weighted RF signals.

2 . The system of claim 1 , wherein associating the one or more RF signals with the user is based on the space and wherein the instructions when executed cause the system to associate the one or more RF signals with the user and the space.

3 . The system of claim 2 , wherein the instructions when executed cause the system to: determine presence of the user in a given space in a given time based on detecting the one or more RF signals.

4 . The system of claim 1 , further comprising:

one or more sensors configured to output signals conveying information related to the user, and wherein the instructions when executed cause the system to:

detect presence of the user within the space based on the output signals; and

associate the one or more RF signals with the user based on the detected presence.

5 . The system of claim 4 , wherein the one or more sensors are configured to output signals conveying information related to RF signals within the space, and wherein the instructions when executed cause the system to:

detect one or more RF signals within the space based on the output signals; and

associate the one or more RF signals with the user based on the detected RF signals.

6 . The system of claim 5 , wherein the instructions when executed cause the system to: detect the one or more RF signals responsive to detecting the user within the space.

7 . A method for determining occupancy within a space, the method being implemented in a computing system comprising at least one processor and memory storing instructions, the method comprising:

obtaining information related to presence of a user within a space; obtaining information related to one or more RF signals within the space, the RF signals including RF signals generated by one or more user devices;

associating one or more RF signals with the user based on the information related to presence of the user and information related to the one or more RF signals;

assigning a weight factor to the RF signals based on a type of the user device emitting the RF signals; and

determining presence of the user based on the association of the user with the one or more weighted RF signals.

8 . The method of claim 7 , wherein: associating the one or more RF signals with the user is based on the space and wherein the instructions when executed cause the system to associate the one or more RF signals with the user and the space.

9 . The method of claim 8 , further comprising: determining presence of the user in a given space in a given time based on the one or more RF signals.

10 . The method of claim 7 , wherein the computing system comprising further comprises one or more sensors, the method further comprising:

detecting presence of the user within the space based on output signals from the one or more sensors; and

associating the one or more RF signals with the user based on the detected presence.

11 . The method of claim 10 , further comprising:

detecting one or more RF signals within the space based on output signals from the one or more sensors; and

associating the one or more RF signals with the user based on the detected RF signals.

12 . The method of claim 11 , further comprising: detecting the one or more RF signals responsive to detecting the user within the space.

13 . A system for determining occupancy within a space, the system comprising:

one or more sensors configured to output signals conveying information related to a user and information related to one or more RF signals within a first space;

at least one processor; and

memory storing instructions executable by the at least one processor, the instructions when executed cause the system to:

detect presence of the user within the first space based on the output signals;

detect a plurality of RF signals within the first space based on the output signals, the plurality of RF signals including RF signals generated by one or more user devices;

associate one or more RF signals from the detected plurality of RF signals with the detected user, the one or more RF signals being emitted by one or more user devices of the user;

assign a weight factor to the RF signals based on a type of the user device emitting the RF signals; and

determine presence of the user in a second space based on detecting the weighted RF signals in the second space.
