In a cellular mobile telephone system, a mobile station requests allocation of a traffic channel by sending a request in a random access channel. The noise suppression sheet permits an extremely compact spiral antenna apparatus while lessening antenna performance degradation. R\u2033 and R\u2032\u2033 can be independently selected from the group consisting of a hydrogen atom, C1 to C6 alkyl groups and halogens. Retrieving values for active network attributes involves generating network traffic. Also, a method for adhering a die onto a support, which may optionally be another die, includes providing a coating of a conformal between the die and the support, and heating the coating between the die and the support. The system can include: a support structure defining a bay, the support structure including support shoes configured to support a container; a sensor for determining a length of a container in the bay; and a controller configured to operate the support structure including a storage mode and a retrieval mode.
