A film-forming composition comprising: a compound having a cage structure; and a silicon-containing surfactant; an insulating film formed by using the composition; and further, an electronic device comprising the insulating film. The measured intensities are compared with at least one reference tag representative of relative intensities emitted by an authentic tag to determine whether the luminescent tag corresponds with any of the at least one reference tag. Contrary to known sensor systems, different detection cycles are implementable in a simple manner using this procedure. The IC also includes a context switching interconnect circuit for switchably connecting the configurable circuit to different sets of storage circuits to receive different sets of configuration data sets. The device has a main tube connected to the releasable coupling via a valve that is manually operated through an operating tube that is connected to the main tube so that it also functions to clear the main tube. A tip of a drumstick is to be inserted within the annular gap and then moved to strike the cymbal plate and cymbal in a single stroke producing a pair of sounds of selected pitches which is to be quickly repeated producing a musical beat.
