A discrimination machine optically senses an object having a surface with a planar structure while scanning the planar structure along the surface. The vertically-extending pillars can be incorporated into transistor devices, and can contain vertically-extending channel regions of the transistor devices. The method for preparing the aripiprazole type I microcrystal allows reduced pollution and loss, great safety, easy and convenient, reduced use of organic solvents, obviated need for demanding process conditions and apparatus, low cost, and facilitated applicability in industrialized manufacturing. Remediation of the pond water to remove selenate down to permissible levels for discharge to lakes and streams is performed by treatment with sulfur-modified iron in a contact bed of an upflow reactor vessel. Next, M vertical block flag values are obtained according to the display line flag values of all of the display lines in each vertical block. The processor is further configured, when the indicator is present, to transmit the emergency call without at least some of the private information to a Public Safety Answering Point 130.
