  • Patent number: 8259286
    Abstract: An apparatus for forming an energy pattern on a target, comprising a projector including a first row of spaced-apart energy outlets arranged in a first pattern, a second row of spaced apart energy outlets arranged in a second pattern, wherein the first pattern is different than the second pattern, and comprising a platform on which the target can be mounted, a motor and a controller. A method of forming a pattern in a layer of energy-sensitive material, comprising projecting a first energy pattern onto the energy-sensitive material, moving the first energy pattern relative to the layer of energy-sensitive material, projecting a second energy pattern onto the energy-sensitive material, wherein the second energy pattern is different than the first energy pattern, and moving the second energy pattern relative to the layer of energy-sensitive material.

  • Patent number: 5528604
    Abstract: Test pattern generation for a sequential logic circuit having combinational logic elements and sequential elements (D flip-flops) is enhanced in generation time and test pattern quality by first transforming the circuit to simplify the circuit for test pattern generation. In one embodiment the retiming transformation is used in which sequential elements are moved across combinational logic elements to increase the ratio of the total number of states which are traversable, and thus simplify the circuit for test pattern generation. The test set generated is equally applicable to the transformed test circuit as well as the manufactured circuit.

  • Patent number: 5025344
    Abstract: A built in current sensor on a unitary substrate with an integrated circuit is provided to sense abnormal quiescent current flow through the integrated circuit after a timing phase as an indication of defects such as shorts and open circuits, while ignoring normal high current peaks. A comparator is provided along with an adjustable reference current to provide a virtual ground voltage which represents that induced by a normal quiescent current through a fault-free integrated circuit. A breaker circuit may be provided for indication, or power disconnection of the integrated circuit, upon the occurrence of current flow above a predetermined value.
