APPARATUS, SYSTEM, AND/OR METHOD FOR MONITORING A DEVICE WITHIN A ZONE
First Claim
1. An apparatus for monitoring a device within a first zone wherein the device is located inside of the first zone in a first position and further wherein the device is located outside of the first zone in a second position, the apparatus comprising:
- a first emitter having a first transmitter that transmits a first signal to establish the first zone that extends from the first emitter;
a head connected to the device wherein the head wirelessly communicates with the first emitter wherein the head has a first receiver that receives the first signal of a first strength indicative of the head in the first position and receives a second signal of a second strength indicative of the head in the second position wherein the head triggers a first alarm in the second position; and
a hub wirelessly communicating with the first emitter and the head wherein the hub has a second receiver that receives the second signal and further wherein the hub triggers a second alarm in the second position of the head.

Abstract
An apparatus, a system and a method monitor a device within a zone. A head may wirelessly communicate with an emitter and a hub. The head may connect and/or disconnect power to a battery of the device according to a charge of the battery. The head may monitor an attachment of the head to the device and/or a connection of a cable to the head and/or a port of the device. The emitter may transmit a signal to define the zone and/or the head may receive the signal. A distance between the head and the emitter may be determined using a received signal strength indication and/or a time of flight measurement of the signal from the emitter to the head. The distance may indicate whether the head is positioned within the zone or outside of the zone. An alarm may be triggered if the head is positioned outside of the zone.

10. A system for determining a proximity of a device to a first zone, the system comprising:
-
a first emitter having a first receiver that receives a first signal and a first transmitter that transmits a second signal to establish the first zone that extends from the first emitter; a head secured to the device wherein the head wirelessly communicates with the first emitter and has a second receiver that receives the second signal wherein the head calculates a distance between the head and the first emitter by determining a time the second signal travels between the first transmitter and the second receiver wherein the distance is indicative of a position of the head and further wherein the head triggers an alarm indicative of the head in a position outside of the first zone; and a hub wirelessly communicating with the first emitter and the head wherein the head transmits a third signal to the hub that is indicative of the device in the position outside of the first zone. - View Dependent Claims (11, 12, 13, 14)

15. A method for monitoring a device within a zone wherein the device wirelessly communicates with a first emitter and a hub and further wherein the zone extends a first distance from the first emitter, the method comprising the steps of:
-
transmitting a signal wirelessly from the first emitter to define the zone wherein the first signal has a frequency; calculating a second distance between the first emitter and the device; comparing the first distance to the second distance; and triggering a first alarm if the second distance is greater than the first distance wherein the first alarm is indicative of the device in a position outside of the zone. - View Dependent Claims (16, 17, 18, 19, 20)
