20140114603 | PSEUDO TESTER-PER-SITE FUNCTIONALITY ON NATIVELY TESTER-PER-PIN AUTOMATIC TEST EQUIPMENT FOR SEMICONDUCTOR TEST - A system and method for testing devices are presented. Embodiments of the present invention use a central controller to coordinate the testing of a plurality of devices under test as well as a plurality of channel circuits that are each operable to be coupled to at least one I/O pin of a device under test of the aforementioned plurality of devices under test. Also, embodiments of the present invention include a plurality of intermediate processors that are each coupled to the central controller and operable to receive and send control signals. These intermediate processors are each coupled to a different set of channel circuits of the plurality of channel circuits and are operable to execute their own instantiation of a test program that is independent of any other intermediate processor of the plurality of intermediate processors for the testing of a device under test associated therewith. | 04-24-2014 |

20100227780 | Methods for the synthesis of arrays of DNA probes - The synthesis of arrays of DNA probes sequences, polypeptides, and the like is carried out using a patterning process on an active surface of a substrate. An image is projected onto the active surface of the substrate utilizing reflective projection optics. The projection optics project a light image onto the active surface of the substrate to deprotect linker molecules thereon. A first level of bases may then be applied to the substrate, followed by development steps, and subsequent exposure of the substrate utilizing a different light image, with further repeats until the elements of a two dimensional array on the substrate surface have an appropriate base bound thereto. | 09-09-2010 |
