Surface plasmon resonance (SPR) sensors comprise a sensor chip constructed of laterally integrated arrays of planar sensor chip units and an optical transducer constructed of laterally integrated arrays of planar optical transducer units. The replaceable sensor chip is separated from the optical transducer by a gap and perpendicular optical interconnections are between the sensor chip and the optical transducer. The optical interconnections between the sensor chip and the optical transducer are based on collimated light beams incident perpendicularly to the interfaces. Uncritical alignment of the optical transducer and the sensor chip is provided. The direction of the light beams will not be changed when passing through the interfaces between the sensor chip, the gap and the optical transducer eliminating the need of disposing refractive index matching gels in the gap.

At periodic interrupts, the method determines which color wheel index mark should be driven into coincidence with the Vsync signal. It does this by measuring the delay between Vsync and any index mark and then based on the current state of the spoke-sync counter and this delay value, a new next state is determined to drive the nearest index mark to Vsync to the Vsync position. At worst case this technique requires only one-half a color wheel revolution of phase correction to re-lock the system when the TV channel is changed and for the 5/2 and 7/2 spoke-sync modes, popular 50 Hz and 60 Hz modes, only one-quarter revolution of phase correction of the color wheel is required for re-lock. iver re-starts the receiving activity.9.
