The invention relates to a process for producing an alkene by non-oxidative dehydrogenation of an alkane, comprising contacting a feed stream comprising the alkane with a catalyst composition comprising an unsupported catalyst comprising ZrV2O7 at a temperature of 400 to 600\xb0 C. A dye imbibed matrix film and blank film are superimposed together in a predetermined registration by rollers in the roll tank, creating a two-film sandwich, which is directed onto the pin belt. The engine stopping position may be indicative of a fraction of injected fuel that enters a cylinder for a first combustion event since engine stop. Advantageously while the call is parked call treatment discrimination can be performed. The packet filtering performed by the NFC controller can also be based on whether the packet was received through an interface with an operating system in the communication device or through an interface with an NFC antenna.
