Tracking safety conditions of an area
Methods and apparatus for electronically quantifying conditions of a person and an environment containing the person, as well as a sequence of positions occupied by the person and a direction the person faced at those positions. Wireless communications track a series of positions over time and provide user interfaces indicating where a person has been and who the person has come within a minimum distance of. In addition, sensors provide ongoing evaluation of a condition of the person, such as a body temperature and heartrate which may trigger an alarm state if the body temperature rises above a specified value. Ongoing environmental conditions may also be quantified and presented in the user interface.
1. A method for tracking safety conditions in an area, the method comprising the steps of:
a. supporting a first agent-supported transceiver by a first person, wherein said first agent-supported transceiver is operative to wirelessly communicate with one or more reference point transceivers;
b. movably supporting a first sensor with the first person, wherein the first sensor is capable of moving with the first person;
c. quantifying a condition present in the area with the first sensor as digital content and associating a first time indicator with the condition;
d. transmitting to a receiver the digital content quantifying the condition present in the area with the agent-supported transceiver;
e. wirelessly communicating between the first agent-supported transceiver and the reference point transceiver a digital value to calculate a distance between the agent-supported transceiver and the reference point transceiver;
f. generating a positional coordinate of the first person based upon the wireless communication;
g. associating a second time indicator with the positional coordinate and the time at which the wireless communication occurred;
h. generating a user interface comprising a physical position of the first person and the quantified condition present in the area;
i. updating the user interface to indicate conditions present in the area and respective positions of persons at specified times;
j. designating one or more conditions conducive to a safety risk; and
k. based upon a condition conducive to a safety risk triggering an alarm state.
2. The method of claim 1 additionally comprising the steps of:
m. repeating steps 1.a-1.h for a second person, where the second person is supporting a second agent-supported transceiver;
n. calculating a distance between the first person and the second person at one or more time instances;
o. determining minimum distance between the first person and the second person; and
p. updating the user interface to indicate respective positions of the first person and the second person.
3. The method of claim 2 additionally comprising the steps of:
q. associating one or more threshold minimum distances with the one or more conditions conducive to a safety risk; and
r. based upon a condition conducive to a safety risk or a minimum distance between the first and second person being lower than a threshold minimum distance associated with a condition conducive to a safety risk, triggering an alarm state.
4. The method of claim 2 , wherein the minimum distance is six feet.
5. The method of claim 1 , wherein the wireless communication between the agent-supported transceiver and the one or more reference point transceivers is achieved via a burst transmission protocol.
6. The method of claim 5 , wherein the burst transmission protocol comprises ultra-wideband.
7. The method of claim 1 , wherein the wireless communication between the agent-supported transceiver and the one or more reference point transceivers is achieved via Bluetooth.
8. The method of claim 1 , wherein the transceiver is in logical communication with a controller.
9. The method of claim 1 , wherein the transceiver is in logical communication with a smart device.
10. The method of claim 9 , wherein a transmission to the transceiver occurs via a low-power wireless communication protocol.
11. The method of claim 10 , wherein the low-power wireless communication protocol comprises Bluetooth Low Energy.

13. The method of claim 1 , wherein the receiver is a reference point transceiver.
14. The method of claim 13 , wherein the communication to the receiver occurs via ultra-wideband.
15. The method of claim 13 , wherein the communication to the receiver occurs via Bluetooth.
16. The method of claim 1 , wherein the positional coordinate comprises a Cartesian coordinate.
17. The method of claim 1 , wherein the positional coordinate comprises a cylindrical polar coordinate.
18. The method of claim 1 , wherein the positional coordinate comprises a spherical polar coordinate.
19. The method of claim 1 , wherein the alarm state comprises activating a signaling device.
20. The method of claim 1 , wherein the alarm state comprises a transmission to a smart device.
21. The method of claim 1 , wherein the alarm state comprises causing an indicator within the user interface to change.
22. The method of claim 1 , wherein the alarm state comprises a notification to one or both of: the first and a second person.
23. The method of claim 1 , further comprising the step of generating an augmented reality interface of a subset of the area based on the position and direction of orientation of an agent-supported smart device.
24. The method of claim 23 , wherein the augmented reality interface further comprises an identifier associated with one or both of the first and second person.
