METHODS AND APPARATUS TO FACILITATE PROXIMITY DETECTION AND LOCATION TRACKING
First Claim
1. A method to facilitate proximity detection and location tracking in an environment, the method comprising:
- receiving messages collected by a badge in the environment, the messages including signal strength and a timestamp;
assigning a location in the environment to the badge based on a first subset of the messages;
identifying an asset in a second subset of the messages; and
updating a current location associated with the asset based on a relative proximity of the asset to the badge, wherein the current location corresponds to a first time and the updated location corresponds to a second time, and wherein a change in location between the current location and the updated location indicates movement of the asset in the environment.

Abstract
Methods, apparatus, systems and articles of manufacture are disclosed to facilitate proximity detection and location tracking. An example method includes receiving messages collected by a badge in an environment, the messages including signal strength and a timestamp. The example method also includes assigning a location in the environment to the badge based on a first subset of the messages. The example method also includes identifying an asset in a second subset of the messages. The example method also includes updating a current location associated with the asset based on a relative proximity of the asset to the badge, wherein the current location corresponds to a first time and the updated location corresponds to a second time, and wherein a change in location between the current location and the updated location indicates movement of the asset in the environment.

1. A method to facilitate proximity detection and location tracking in an environment, the method comprising:
-
receiving messages collected by a badge in the environment, the messages including signal strength and a timestamp; assigning a location in the environment to the badge based on a first subset of the messages; identifying an asset in a second subset of the messages; and updating a current location associated with the asset based on a relative proximity of the asset to the badge, wherein the current location corresponds to a first time and the updated location corresponds to a second time, and wherein a change in location between the current location and the updated location indicates movement of the asset in the environment. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

15. An apparatus to facilitate proximity detection and location tracking in an environment, the apparatus comprising:
-
a message receiver to receive messages collected by a badge in the environment, the received messages to include signal strength and a timestamp; a badge location engine to assign a location in the environment to the badge based on a first subset of the messages that correspond to a timestamp interval; and an asset location engine to; identify an asset in a second subset of the messages that correspond to mobile-location assets; and update a current location associated with the asset based on a relative proximity of the asset to the badge, the current location to correspond to a first time and the updated location to correspond to a second time, and a change in location between the current location and the current location indicative of movement of the asset in the environment. - View Dependent Claims (16, 17, 18, 19)

20. A tangible machine-readable storage medium comprising instructions that, when executed, cause a machine to at least:
-
receive messages collected by a badge in an environment, the received messages to include signal strength and a timestamp; assign a location in the environment to the badge based on a first subset of the messages that correspond to a timestamp interval by; identifying a proximate beacon tag relative to the badge based on the signal strength; and assign a fixed-location associated with the proximate beacon tag to the badge; identify an asset in a second subset of the messages that correspond to mobile-location assets; and update a current location associated with the asset based on a relative proximity of the asset to the badge by; classifying an asset location relative to the badge based on the signal strength; in response to classifying the asset location as immediate relative to the badge; associating the location assigned to the badge to the asset; and incrementing a confidence score associated with the asset; and in response to classifying the asset location as near relative to the badge; incrementing the confidence score associated with the asset when the current location associated with the asset matches the location of the badge; and decrementing the confidence score associated with the asset location when the current location associated with the asset is different from the location of the badge, wherein the current location is to correspond to a first time and the updated location is to correspond to a second time, and a change in location between the current location and the updated location is to indicate movement of the asset in the environment.
