A method and suspension apparatus for suspending an object in a vehicle. The packet is formed of a multilayer laminate material having interior and exterior polymer layers and an intermediate metallic foil layer. When the communication device is in a second operational state, received data is encrypted using a second cryptographic key and algorithm. Accordingly, even though encoding or decoding is performed using a small number of bits, there is no degradation in sound quality of a signal corresponding to a high frequency band, and thus coding efficiency can be maximized. The system also includes a structure such as floor having a cavity for receiving the panel assembly. The catch device is a basket having walls made of mesh.
