Abstract: A measurement method configured to measure a stereoscopic display includes: causing at least three different displaying positions to emit lights corresponding to a first viewing zone and measuring light intensities of the lights emitted by the displaying positions corresponding to the first viewing zone to respectively obtain at least three sets of first view light intensity distribution data, causing at least three different displaying positions to emit lights corresponding to the second viewing zone and measuring light intensities of the lights emitted by the displaying positions corresponding to the second viewing zone to respectively obtain at least three sets of second view light intensity distribution data, and calculating a set of total comprehensive distribution data according to the first and second view light intensity distribution data. A measurement apparatus and a computer program product are also provided.

Abstract: A residue removal device includes an object, a sink, and a conveying device. The object includes a contact surface. Residue exists on the contact surface. A solution is contained in the sink. The sink is disposed below the contact surface. The solution corresponds to the contact surface. The conveying device drives the relative motion between the object and the sink. When the residues on the contact surface are contacted by the solution and relative motion is generated between the residues of the contact surface and the solution, the residues are removed by the solution.

Abstract: A pivotal tool device includes two arms each having two driving tool members disposed on the ends. One of the arms includes a shank extended from a middle portion, and the other arm includes a chamber formed in the middle portion, for selectively receiving the shank, to allow the arms to be solidly engaged with each other, and to have a greatly increased driving torque formed between the arms. The shank includes a non-circular cross section for engaging with the non-circular chamber of the other arm. A detent may selectively anchor the arms together. A spring element may selectively bias the arms away from each other.
