Abstract: 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.

Abstract: 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.

Abstract: An example disclosed method for determining player performance information associated with a player carrying a first tag moving about a monitored area includes receiving first blink data from a plurality of receivers disposed about the monitored area, wherein the first blink data is generated by the first tag carried by the player moving about the monitored area; weighting the first blink data by: when the player is in a pre-play formation, assigning a first weight to the first blink data; and in response to receiving the play-start indication, assigning a second weight to the first blink data, the second weight being greater than the first weight; determining tag location data based on the weighted first blink data; and determining player performance information based on the tag location data.

Abstract: An example method for providing enhanced event visualizations based on location data includes receiving, by a visualization processor, location data and sensor data for a plurality of participants; determining an impact indication for two or more participants of the plurality of participants based at least in part on the location data and sensor data; determining, by the visualization processor, a location of impact based on the impact indication and the location data and sensor data for the two or more participants; and generating an impact visualization interface configured to visually indicate impact data associated with the impact indication proximate the impact location.

Abstract: A method of object identification includes: capturing an image of an object having a material presenting surface artifacts; detecting a boundary within the captured image; selecting a portion of the image depicting the surface material within the boundary; based on the selected portion of the image, determining attributes of the surface artifacts; generating, based on the determined attributes of the surface artifacts, a physical identifier corresponding to the object; and storing the generated physical identifier.

Abstract: An example method includes sensing, by a sensor of a mesh node, first sensor data; receiving, at the mesh node, second sensor data from an origin node, wherein the mesh node and the origin mode are different nodes; and in response to receiving an indication that the origin node is obstructed, transmitting, by the mesh node, the second sensor data.

Abstract: Systems and methods for detecting an event within a monitored area are provided. A transmitter emits an RF interrogation signal into the monitored area. An RF target positioned within the monitored area reflects the interrogation signal as a target signal when the interrogation signal impinges on the RF target. The RF target has a switch actuatable by a user between a switch-state in which the RF target operates in a first reflective state, and a switch-state in which the RF target operates in a second reflective state. A receiver receives the target signal from the RF target. Based on the target signal received by the receiver, a processor can detect an indication of the reflective state in which the RF target is operating. The processor triggers an action in response to the indication of the reflective state in which the RF target is operating.

Abstract: Systems, methods, apparatuses, and computer readable media are disclosed for improving, in some examples, backhaul of sensor and other data to a real time location system (RTLS) network. In the context of a method for communication by a tag, the method includes receiving, at the tag, sensor data from at least one sensor, generating, using a processor of the tag, a tag blink data packet, the tag blink data packet including a tag identifier and at least a portion of the received sensor data, and transmitting the tag blink data packet.
