Personal tracking device
View Patent ↗A system for monitoring the location of individuals, such as parolees, includes a wearable device worn by the individual and a portable device operatively coupled to the wearable device. The portable device is operatively coupled to a monitoring system through a wireless telephone network. The portable device transmits periodically encrypted location information as well as status information across the wireless network to the monitoring system. The monitoring system tracks the location of the individual and alerts the appropriate authorities when the individual violates a rule, such as a condition for parole. The portable device increases the time between transmissions when the individual is within a specified home location and reduces the time between transmissions when outside the specified location.
1. A method, comprising:
monitoring a monitored individual with a tracking device, wherein the tracking device includes a wearable device worn by the monitored individual, wherein the tracking device is operable to determine location of the monitored individual;
sending status messages concerning the monitored individual to a monitoring system on an intermittent basis with the tracking device;
pausing said sending the status messages while the tracking device processes a communication between the monitored individual and at least one other person; and
resuming said sending the status messages after the communication between the monitored individual and the other person ceases.
2. A method, comprising:
determining location of a monitored individual with a tracking device;
sensing that the monitored individual is generally motionless with the tracking device;
ceasing processing of the location of the monitored individual upon said sensing, wherein said ceasing processing includes transmitting the location of the monitored individual with a reading alert flag over a network from the tracking device to a monitoring system;
detecting motion of the monitored individual with the tracking device after said ceasing processing; and
reinitiating processing of the location of the monitored individual upon said detecting.
3. The method of claim 2 , wherein said ceasing processing includes stopping said determining the location of the monitored individual with the tracking device.
4. The method of claim 2 , wherein said ceasing processing includes terminating transmission of the location of the monitored individual to a monitoring system.
5. The method of claim 2 , wherein said ceasing processing includes skipping evaluation of selected rules in the tracking device.
6. The method of claim 2 , further comprising:
wherein the tracking device includes a GPS receiver and a motion sensor;
wherein said determining includes determining the location of the monitored individual with the GPS receiver;
wherein said sensing includes sensing that the monitored individual is generally motionless with the motion sensor; and
wherein said ceasing processing includes stopping said determining the location of the monitored individual to reduce drift in location readings.
7. The method of claim 6 , further comprising:
detecting motion of the monitored individual with the motion detector after said ceasing processing; and
reinitiating processing of the location of the monitored individual upon said detecting.
8. The method of claim 6 , wherein the GPS receiver determines only a single GPS reading to conserve power during said determining the location of the monitored individual.
9. The method of claim 6 , wherein the tracking device includes a wearable device worn by the monitored individual.
10. The method of claim 2 , wherein the tracking device includes a wearable device worn by the monitored individual.
11. The method of claim 10 , further comprising:
wherein the tracking device includes a mobile telephone in possession of the monitored individual; and
transmitting a status message from the wearable device to the mobile telephone.
12. The method of claim 1 , further comprising:
wherein the tracking device includes a mobile telephone;
receiving a telephone call with the mobile telephone, wherein communication between the monitored individual and the at least one other person includes the telephone call; and
said pausing said sending the status messages occurs in response to said receiving the telephone call.
