Image capture data is output from an image capture device, e. A central station inserts a marker into a transmitted signal at a time corresponding to a received timing signal. The valve system may comprise a common rail fuel injector, electrohydraulic actuator system, electronically-controlled fuel injector, gasoline port injector, fluid metering valve, relief valve, reducing valve, direct valve or direct-injection gasoline injector. The inner end of each of the seals has a lobe formed therein which is embedded in the respective panels. Alternatively, in another embodiment, the halftoned image appears as the same image under different viewing conditions.
