Abstract

A device comprises a gas cushion inflatable with gas by a filling device, a transceiver for electromagnetic waves, an evaluation device connected to the transceiver, and an interrogation unit, disposed on the gas cushion, that can be remotely interrogated by the transceiver to provide a degree of deployment and/or deployment velocity of the gas cushion to the evaluation device. The interrogation unit can be implemented by a transponder or a polarizing reflector.

Claims

1. A device, comprising:

a gas cushion configured for inflation with gas by a filling device;

a transceiver for electromagnetic waves; and

an evaluation device connected to the transceiver, wherein there is disposed on the gas cushion at least one interrogation unit which can be interrogated in a contactless manner by the transceiver and information about at least one of a degree of deployment and a deployment velocity of the gas cushion is provided in the evaluation device, wherein

the interrogation unit is implemented by a polarizing reflector.

2. A device, comprising:

a gas cushion inflatable with gas by a filling device;

a transceiver for electromagnetic waves;

an evaluation device connected to the transceiver; and

an interrogation unit, disposed on the gas cushion, that can be remotely interrogated by the transceiver to provide at least one of a degree of deployment and a deployment velocity of the gas cushion to the evaluation device, wherein

the interrogation unit is implemented by a transponder, and

the transponder is implemented by a logic circuit which enables an encoded wave to be transmitted back to the transceiver.
