What is disclosed is a system and method for determining whether a front seat in a motor vehicle is occupied based on seat pattern recognition. The emulator may transmit the information in order to reduce the amount of circuitry needed to emulate a particular block of information. This way, the gearing of the startup process can be configured long, even when using a so-called hard torque converter, without having to tolerate a creeping velocity, which is too high. In yet another extended embodiment, the present invention discloses different ways for screening multiple GPCRs in a single type of cell or multiple GPCRs in multiple types of cells within a single medium solution. The method includes steps of providing a substrate, spreading a catalyst on the substrate, putting the substrate into a reactor, introducing a carbon containing material, and heating the carbon containing material, thereby the carbon containing material being cracked to provide a carbon source for forming the nano-carbon material on the substrate.
