Abstract

A modular location tag, method of manufacture, and method of use thereof are provided. The modular location tag including a controller including a microcontroller configured to generate a data packet and a two or more individual transmit modules in data communication with the controller such that each individual transmit module is configured to transmit the data packet, each individual transmit module including an antenna and a pulse generator configured to transmit the data packet on ultra-wideband (UWB) blink data pulses. The controller causes substantially simultaneous transmission of the UWB blink data pulses from the respective transmit modules encourage reliable receipt of the UWB blink data pulses at one or more of a plurality of receivers.

5. The wearable modular location tag system of claim 1 , wherein component based signal delays of the respective individual transmit modules of the two or more individual transmit modules are matched, and
wherein the substantially simultaneous transmission of the blink data pulses is based at least in part on the matched component based signal delays.

6. The wearable modular location tag system of claim 1 , wherein the microcontroller is further configured to trigger the transmission of the blink data pulses based on component based signal delays associated with the respective individual transmit modules, and
wherein the substantially simultaneous transmission of the blink data pulses is based at least in part on the triggering of the transmission of the blink data pulses.

7. The wearable modular location tag system of claim 1 , wherein the controller or two or more of individual transmit modules are encased in an impact resistant enclosure.

8. The wearable modular location tag system of claim 1 , wherein the controller and the two or more individual transmit modules are configured to be mounted to a participant defining a front and back, wherein a first transmit module of the two or more individual transmit modules is configured to be mounted to the front the participant and a second transmit module of the two or more individual transmit modules is configured to be mounted to the back of the participant.

9. The wearable modular location tag system of claim 1 , wherein the controller and the two or more individual transmit modules are configured to be mounted to a participant defining a front and back, wherein a first transmit module of the two or more individual transmit modules is configured to be mounted to a right front portion of the participant, a second transmit module of the individual transmits modules is configured to be mounted to a front left portion of the participant, a third transmit module of the two or more individual transmit modules is configured to be mounted to a back right portion of a participant, and a fourth transmit module of the individual transmit modules is configured to be mounted to a back left portion of the participant.

10. The wearable modular location tag system of claim 1 , wherein the controller and two or more transmit modules are incorporated into a participant protective equipment.

11. The wearable modular location tag system of claim 1 , wherein the controller and the two or more transmit modules are incorporated into a participant clothing.

12. The wearable modular location tag system of claim 1 , wherein the controller is mounted to a participant belt.

13. The wearable modular location tag system of claim 1 further comprising:
an environmental sensor in data communication with the microcontroller; and
wherein the microcontroller is further configured to receive environmental data from the environmental sensor.

14. The wearable modular location tag system of claim 13 , wherein the environmental sensor is an accelerometer.

15. The wearable modular location tag system of claim 14 , wherein the controller drives the substantially simultaneous transmission of the blink data pulses at a first rate based on the accelerometer outputting accelerometer data in a first value range and at a second rate based on the accelerometer outputting accelerometer data in a second value range.

16. The wearable modular location tag system of claim 13 , wherein the environmental sensor is at least one of a heart rate monitor, a humidity sensor, a temperature monitor, a moisture sensor, a breathing sensor, a global position sensor, a proximity sensor, or a pedometer.
