Locating an EMS unit closest to a source of a distress signal and notifying proximate personal devices

1 . A method comprising:

receiving a distress signal from a first personal device;

locating an EMS unit closest to the first personal device;

transmitting a location of the first personal device to the EMS unit indicating that a user of the first personal device is in distress;

identifying a second personal device proximate to the first personal device; and

transmitting a notification signal to the second personal device indicating that a person is in distress and instructing a user of the second personal device to clear a path for the EMS unit.

2 . The method of claim 1 , wherein at least one of transmitting or receiving is via an Ultra Wide Band (UWB) communication link.

3 . The method of claim 1 , wherein the distress signal is based on detection of at least one of an abnormal heartbeat, an abnormal blood oxygen saturation, or an abnormal body temperature.

4 . The method of claim 1 , wherein the notification signal causes the second personal device to at least one of illuminate, vibrate, or display a message.

5 . The method of claim 1 , comprising transmitting a location assistance signal to the first personal device.

6 . The method of claim 5 , wherein the location assistance signal causes the first personal device to activate at least one of an alarm or an LED.

7 . The method of claim 1 , wherein locating the first personal device relative to the EMS unit is performed using triangulation.

8 . A system comprising:

a control circuit to:

receive a distress signal from a first personal device in a crowded public space;

locate an EMS unit closest to the first personal device;

transmit a location of the first personal device to the EMS unit indicating that a user of the first personal device is in distress;

identify a second personal device proximate to the first personal device; and

transmit a notification signal to the second personal device indicating that a person is in distress and instructing a user of the second personal device to clear a path for the EMS unit.

9 . The system of claim 8 , wherein the distress signal is received using an Ultra Wide Band (UWB) communication link.

10 . The system of claim 8 , wherein the distress signal indicates the user of the first personal device is experiencing at least one of an abnormal heartbeat, an abnormal blood oxygen saturation, or an abnormal body temperature.

11 . The system of claim 8 , wherein the notification signal causes the second personal device to at least one of illuminate, vibrate, or display a message.

12 . The system of claim 8 , the control system to transmit a location assistance signal to the first personal device.

13 . The system of claim 12 , wherein the location assistance signal causes the first personal device to activate at least one of an alarm or an LED.

14 . The system of claim 8 , wherein locating the first personal device relative to the EMS unit is performed using triangulation.

15 . A system comprising:

a control circuit to:

monitor a vital sign of a user of a first personal device;

determine whether the user is in distress based on the vital sign;

transmit a distress signal to a server; and

receive a notification signal indicating that a person near the user is in distress, the notification signal instructing the user to clear a path for an EMS unit to reach the person.

16 . The system of claim 15 , wherein the distress signal is transmitted using an Ultra Wide Band (UWB) communication link.

17 . The system of claim 15 , wherein determining whether the user is in distress is based on detecting at least one of an abnormal heartbeat, an abnormal blood oxygen saturation, or an abnormal body temperature.

18 . The system of claim 15 , the control circuit to:

receive a location assistance signal; and

activate a location assistance circuit to illuminate the first personal device.

19 . The system of claim 15 , wherein the control circuit to:

receive a location assistance signal; and

activate an LED.

20 . The system of claim 15 , the control circuit to:

receive a notification signal; and

activate a sensory circuit.
