A spectral correlator comprises a specimen and an optical device configured to collect light from the specimen and to optically determine a similarity of a received first spectra of the light collected from the first spectra and a second known spectra. The locking ridge extends radially inward from an inner surface of the wellhead into a well bore. The replacement module includes a consumable such as toner or ink, which is consumed during rendering of images by the respective marking engine. A step control block controls the displacement calculation block and signal production block so that they will act cyclically. Capacitors C1 and C2 are connected in parallel to the drain-source regions of the transistors Q1 and Q2 to increase the total drain-source capacitance and reduce the resonance frequency, so that unwanted electromagnetic wave radiation in a frequency band affecting other electronic devices is suppressed. The GPS information is transferred from the telephone to a navigation module in a vehicle which displays a map showing the route to the restaurant.
