Abstract: An apparatus and method for automatically blocking and providing measurement of a lens blank during the blocking process includes an alignment station and a blocking station. The alignment station aligns a lens blank to a block for bonding that is also known as the blocking process. The blocking station includes a lens blank measurement system having sensors that automatically identify and determine measurement and alignment information about the lens, such as sag and tilt of the lens blank, during the blocking process.

Abstract: Disclosed herein is a holding device, which includes a volumetrically controllable material and a volume controller in operable communication with that material. The volume controller is configured to subject the material to a condition that causes a physical change in volume of the material without a change in mass of the material. The volumetric change causes the holding power. Further disclosed herein is a method for creating a lower than atmospheric pressure between a volumetrically controllable fixed mass material and a separate object. The method includes introducing to the material an increase condition calculated to volumetrically increase the material without changing the mass of the material. The separate object is then brought to contact the material following which a decrease condition calculated to volumetrically decrease the material without changing the mass of the material is introduced to the material.
