Higher mixed alcohols are produced from syngas contacting a catalyst in a reactor. The light sensor includes a light-sensing unit, and the black matrix includes a semi-transparent film corresponding to the light-sensing unit. Exemplary embodiments of the present invention generally provide for improved accuracy of range finders, magnetometers and inclinometers as well as for improved prediction of moving target positions. Scheduled changes are retrieved from a data store accessible by the processor. In one embodiment, the entrance of the inlet can be positioned beneath the wing, and the exit of the nozzle can be positioned at or above the wing.
