A multi-functional scanner and method of assembling same. In the methodapparatus, before the coloring, landing locations for the plural ink dots to be ejected to color the filter elements, are measured and based on the measurement results, ejection timings for the plural nozzles are adjusted so that the plural ink dots land along the center line of each of the filter elements in the first direction. The conventional active noise cancellation systems mainly use the LMS which considers secondary statistics among input signals. The container is adapted to be attached to a surgical instrument in such a way that the latch assembly is prevented from opening until the container is removed from the instrument. The PCU can clock gate at least one of the logic units and the cache memory when the multi-core processor is in a low power state to thus reduce dynamic power consumption.
