A method and apparatus for synchronizing actions of two circuits or two parts of one circuit where each circuit utilizes a different clock signal. The drive tool can be guided in a receiving recess of a connecting partner, in particular in a receiving recess of the screw, and transmit the drive torque during a rotation about a central axis. The detection device further comprises a selector system, connected to each of the detectors, embodied to successively select each of the detectors and to transmit a received signal from the selected detector. The graphical map interface can also be configured to display an indication of the frequency of an event. The resulting semiconductor resistor element could have a fixed resistance, or could have a variable resistance. The spectral output of the light source has three peaks located in the same areas of the spectrum where LCD color filters transmit most of the light, thereby providing a balanced white.
