Abstract: A photopolymerizable composition for a color filter, which comprises a photopolymerization initiator system, a compound having at least one ethylenically unsaturated double bond, a colorant, and a phosphoric (meth)acrylate compound and/or an organic carboxylic anhydride having a molecular weight of at most 800, wherein the content of the colorant is from 20 to 90 wt % based on the total solid content.

Abstract: A method and apparatus for controlling the motion of a redundancy manipulator in which the redundancy manipulator has at least seven axes. The optimal estimate function is calculated for the target posture among an infinite number of (possible) elbow postures of the redundancy manipulator to ensure that the elbow reaches its target position at least before the hand position or posture values reaches its targeted value. The elbow posture of said redundancy manipulator is controlled based on the estimate function K.
