First Claim
Patent Images
1. A platform system comprising:
- a plurality of elevated platforms;
a plurality of platform identification devices, each identification device associated with one of the platforms, each identification device wirelessly broadcasting a signal at a first frequency within the confines of its associated platform, the signal including a unique identifier of the associated platform; and
a plurality of restraining systems, each restraining system including first and second interlockable parts, an RFID tag attached to the first part, and an RFID reader coupled to the second part for near field detection of the tag within a prescribed range of the second part, the RFID reader including a telemetry module for receiving a unique platform identifier from one of the identification devices and for broadcasting a status signal to a base station at a second non-interfering frequency with the identification devices.

Abstract
A restraining system comprises a restraining device including first and second interlockable parts that, when interlocked, restrain the system. The restraining system further comprises a passive RFID tag attached to the first part, and a passive RFID reader coupled to the second part for near field detection of the tag within a prescribed range of the second part.

5. A platform system comprising:
-
a platform; a device onboard the platform, for wirelessly broadcasting a signal at a first frequency that identifies the platform with a unique identifier, power and gain of the signal tailored so the signal is broadcast within the confines of the platform; and a restraining system including a plurality of first and second interlockable parts, an RFID tag attached to each first part, and an RFID reader coupled to each second part performing near field detection of the tag to determine interlock status of the first and second parts, the RFID reader including a telemetry module for receiving the unique platform identifier and for broadcasting a status signal to a base station at a second non-interfering frequency with the device onboard the platform, the status signal indicating the unique platform identifier and the interlock status. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)
