US Patent:

20220319179, Oct 6, 2022

Filed:

Mar 10, 2022

Appl. No.:

17/691695

Inventors:

- Philadelphia PA, US
Rui Min - Vienna VA, US
Hong Li - Mount Laurel NJ, US
Ruichi Yu - College Park MD, US

International Classification:

G06V 20/52

Abstract:

A camera system may automatically identify high frequency motion regions in a field of view of the camera system. Analysis of motion events detected at different regions of a scene in the field of view, may be performed. Similar events frequently occurring at a certain region may be recorded/accumulated and compared to a threshold. Regions with high frequency activity may be determined and a user may be notified. If the user is not interested in events within the high activity regions, the regions may be ignored and notifications to the user may cease. The camera system may determine specific actions/events occurring in a region, such as a person approaching or leaving a home.

International Classification:

H04W 4/021
H04B 17/318
H04W 24/08
H04L 67/55

Abstract:

Systems, apparatuses, and methods are described for presence detection of a wireless device in a sensing region. Communication parameters determined by a computing device over one or more periods may be used to generate criteria for determining the occurrence of enter events or leave events. The criteria may comprise, for values of one or more communication parameters, rates of change associated with movement into or out of the sensing region. The criteria may be compared against subsequent data associated with the communication parameters to determine if an enter event or a leave event has occurred.

Abstract:

Systems, apparatuses, and methods are described for presence detection of wireless device in a sensing region. Communication parameters determined by a computing device over one or more periods may be used to generate criteria for determining occurrence of enter events or of leave events. The criteria may comprise, for values of one or more communication parameters, rates of change associated with movement into or out of a sensing region. The criteria may be compared against subsequent data, associated with the communication parameters, to determine if an enter event or a leave event has occurred.
