An example method includes determining that first locations of a first location tag and second locations of a second location tag indicate that the first location tag is moving at a different rate than the second location tag; and, in response to determining that the first and second locations indicate that the first location tag is moving at a different rate than the second location tag at a first time, determining a distance magnitude between the first location tag and the second location tag at the first time; comparing the distance magnitude to a reference distance; and determining, based on the comparing of the distance magnitude to the reference distance, whether the first and second locations indicate that a type of movement of an asset is rotational.

Method, apparatus, and computer program product for employing a spatial association model in a real time location system

A method includes generating registration data, wherein the registration data comprises at least a tag-individual correlator and a status, receiving a status change indication, for at least one tag, wherein the at least one tag is identified by a tag unique identifier; correlating the tag unique identifier and the tag-individual correlator in the registration data; and updating the status in the registration data for the status change indication.

Methods and apparatus to correlate unique identifiers and tag-individual correlators based on status change indications

An example for processing location information received from a radio frequency (RF) location tag includes determining a first location of a first RF location tag associated with an asset; determining at least one second location of at least one second RF location tag associated with the asset; determining, using a processor, that the first location is not a valid location based at least in part on a comparison of the first location with the at least one second location using a spatial association model associated with the asset; and identifying the first location as erroneous in response to determining that the first location is not a valid location.

An example method includes calculating a tag data filter parameter for a plurality of tag events based on received tag blink data and tag location data, wherein the tag data filter parameter comprises a blink period, distance span, or velocity, calculating a participant location data adjustment factor based on the tag data filter parameter, and calculating multidimensional player location information per unit time based on the plurality of tag events and the participant location adjustment factor.

Systems, methods, apparatuses, and computer readable media are disclosed for associating a radio frequency identification tag with a participant. In one embodiment, a method is provided for associating an unassociated RF location tag with a participant. The method may include determining an unassociated RF location tag to be associated with the participant, receiving sensor derived data from one or more sensors, determining an identity of the particular participant using the sensor derived data, and associating the identity of the particular participant with the unassociated RF location tag.

Method and apparatus for associating radio frequency identification tags with participants

An apparatus and method for tracking a large number of wireless terminals being used by wireless subscribers and for estimating the location of the terminals at each instant. Some embodiments of the present invention use a combination of cluster analysis, interpolation of information between identified clusters, and averaging of the interpolated information, in order to predict when it might be beneficial to issue a location request to a location engine, for each subscriber.

Tracking large numbers of wireless terminals based on predicting when to issue location requests

An example disclosed method for registering an unregistered radio frequency (RF) location tag carried by a participant includes receiving blink data from an unregistered RF location tag; determining a tag location based on the blink data received from the unregistered RF location tag; directing a camera to view the tag location determined based on the blink data received from the unregistered RF location tag; identifying a participant at the tag location using image data obtained by the camera; and registering the unregistered RF location tag with the identified participant.

Method, apparatus, and computer program product improving registration with real time location services

An apparatus and method for tracking a large number of wireless terminals being used by wireless subscribers in a wireless network and for estimating the location of the terminals at each instant. Some embodiments of the present invention use a coordinated smoothing over time of when location requests should be issued to a location engine, for the large number of subscribers. The smoothing can be used in conjunction with a throttling of location requests, such as when the maximum rate of location request transactions that is supported by the wireless network is exceeded.

Tracking large numbers of wireless terminals while regulating location requests

Systems, methods, apparatuses, and computer readable media are disclosed for over-determining location estimations for an asset based on location estimates from a plurality of tags. Examples employ a spatial association model in a location system. Examples include a method for processing location information received from a radio frequency (RF) location tag. The method includes determining a first location of a first RF location tag associated with an asset, determining at least one second location of at least one second RF location tag associated with the asset, determining, using a processor, that the first location is not a valid location based at least in part on a comparison of the first location with the at least one second location using a spatial association model associated with the asset, and identifying the first location as erroneous in response to determining that the first location is not a valid location.

Systems, methods, apparatuses, and computer readable media are disclosed for improving, in some examples, registration of radio frequency tags with a location system. Example embodiments may include a method for registering a participant with a radio frequency (RF) location tag. The method may include determining tag derived data from the one or more registered RF location tags, identifying at least one unregistered RF location tag, determining an identity of a participant for registration with the unregistered RF location tag based at least in part on the tag derived data from the one or more registered RF location tags, and registering the unregistered RF location tag with the participant.
