RADIO FREQUENCY IDENTIFICATION SAFETY SYSTEM
First Claim
1. A safety system comprising:
- a transponder comprising;
a microchip having embedded therein electronically programmed unique identification information; and
an internal power supply;
a reader coupled to a power supply of a piece of equipment, the reader comprising;
a transceiver; and
a scanning antenna which outputs a first radio-frequency signal to a pre-programmed radius;
a base unit comprising a programmable logic controller; and
a remote alarm,wherein the reader is put into an active state capable of receiving information from the transponder only when the power supply of equipment is flowing, and further wherein when the transponder encroaches on the pre-programmed radius, the radio-frequency signal of the active reader identifies the transponder'"'"'s unique identification information, the transponder transmits data through radio waves to the transceiver using the internal power supply, and the transceiver sends a second radio wave signal to the base unit causing the programmable logic controller to trigger the remote alarm.

Abstract
A safety system indicating encroachment near dangerous equipment which is activated upon activation of the equipment is provided. The safety system has a transponder having unique identification information embedded in a microchip and an internal power supply. A corresponding reader is coupled to a power supply of the equipment, and has a transceiver and a scanning antenna which outputs a first radio-frequency signal to a pre-programmed radius. When the power supply of the equipment is flowing, the reader is put into an active state capable of receiving information from the transponder. When the transponder encroaches on the pre-programmed radius, the signal of the reader identifies the transponder'"'"'s identification information, the transponder transmits data to the transceiver using the internal power supply, and the transceiver sends a second radio wave signal to a base unit causing a programmable logic controller to trigger a remote alarm.
