Abstract

This disclosure presents various means for securing a tracking beacon to personal protection equipment. The tracking beacon mount is constructed of a cover, a base, a transmitter and a mounting mechanism, such as a strap. The transmitter has a unique identifier which is detected by a proximity sensor. The proximity sensor is operably connected to a tracking system which can be used to detect the presence of the beacons. The system is programmed to recognize the types of items used and warn the user if something predetermined as required for the location or job type is missing.

Claims

1. A radio frequency (RF) monitoring system, comprising:

a housing comprising;

a base forming a cavity;

a RF transmitter, disposed entirety within the cavity formed in the base, operable to transmit a monitoring signal having a unique identifier;

a battery, disposed entirely within the cavity formed in the base, operable to provide power to the transmitter; and

a cover, removeably attached to the base over the cavity, for enclosing the cavity;

a proximity sensor operable to receive the monitoring signal from the transmitter; and

a controller in communication with the proximity sensor operable to generate an output indicative of the proximity sensor receiving the monitoring signal from the transmitter;

wherein the base and the cover cooperate to form a strap channel within the housing and wherein the strap channel defines a curved, tortuous path that extends between a first opening formed in the housing and a second opening formed in the housing for moveably securing the housing to a strap and wherein the curved, tortuous path defined by the strap channel includes an entry opening formed in the housing and a ninety degree turn near a respective one of the first opening and the second opening.

2. The RF monitoring system as recited in claim 1, wherein the battery comprises a rechargeable battery.

3. A radio frequency (RF) monitoring system, comprising:

a housing comprising;

an first clamp portion forming a cavity;

a RF transmitter, disposed within a first portion of the cavity formed in the first clamp portion, operable to transmit a monitoring signal having a unique identifier;

a battery, disposed within a second portion of the cavity formed in the first clamp portion, operable to provide power to the transmitter;

a cover having a first cover portion, removeably attached to the first clamp portion over the first portion of the cavity formed in the first clamp portion, and a second cover portion, removeably attached to the first clamp portion over the second portion of the cavity formed in the first clamp portion, for enclosing the cavity;

a second clamp portion pivotally coupled to the first clamp portion and moveable between a clamp closed position in which a first end of the first clamp portion is positioned adjacent to a first end of the second clamp portion and a clamp open position in which the first end of the first clamp portion is spaced from the first end of the second clamp portion; and

a spring cooperable with the first clamp portion and the second clamp portion to bias the second clamp portion towards the clamp closed position;

a proximity sensor operable to receive the monitoring signal from the transmitter; and

a controller in communication with the proximity sensor operable to generate an output indicative of the proximity sensor receiving the monitoring signal from the transmitter;

wherein a second end of the first clamp portion and a second end of the second clamp portion are arranged to receive a force for moving the first clamp portion and the second clamp portion between the clamp closed position and the clamp open position for removeably securing the housing to an article of clothing.

4. The RF monitoring system as recited in claim 3, wherein the first end of a one of the first clamp portion and second clamp portion has a plurality of projections and the first end of the other one of the first clamp portion and the second clamp portion has complementary indentations into which is received the plurality of projections.

5. The RF monitoring system as recited in claim 3, wherein the battery comprises a rechargeable battery.
