Abstract: A method for configuring an automated in-circuit test debugger is presented. The novel test debug and optimization configuration technique configures expert knowledge into a knowledge framework for use by an automated test debug and optimization system for automating the formulation of a valid stable in-circuit test for execution on an integrated circuit tester. In a system that includes a rule-based controller for controlling interaction between the test-head controller of an integrated circuit tester and an automated debug system, the invention includes a knowledge framework and a rule-based editor. The knowledge framework stores test knowledge in the representation of rules that represent a debugging strategy. The rule-based editor facilitates the use of rules as knowledge to debug or optimize an in-circuit test that is to be executed on the integrated circuit tester.

Abstract: An optical encoder includes a code strip having a first side, a second side, a first track comprising indicia thereon, and a second track comprising indicia thereon. The code strip is moveable along a displacement path with respect to the optical encoder. A light source positioned on the first side of the code strip directs light toward the code strip. A first detector element is positioned on the second side of the code strip and is generally aligned with the first track of the code strip. A second detector element is positioned on the second side of the code strip and is generally aligned with the second track of the code strip. The second detector element is also positioned so that the second detector element is located a spaced distance along the displacement path from the first detector element.

Abstract: A Low-Cost Absolute Linear Optical Encoder (“LALOE”) for determining the absolute position of a read-head within the LALOE relative to a codestrip is disclosed. The LALOE may include an emitter module within the read-head, the emitter module having a plurality of light sources arranged in an light source pattern and a 90° Out-Of-Phase light source; and a detector module within the read-head, the detector module having a plurality of photo-detectors arranged in a photo-detector pattern corresponding to the light source pattern and a 90° Out-Of-Phase photo-detector corresponding to the 90° Out-Of-Phase light source.

Abstract: A composition for reducing pain at a surgical wound site or trauma site comprising oxidized regenerated cellulose and a non-steroidal anti-inflammatory drug or pharmaceutically acceptable salt or ester thereof, where the non-steroidal anti-inflammatory drug is an acid having a secondary amine group; and a method of reducing localized pain at a surgical wound site or trauma site.

Abstract: An apparatus and method for detecting characteristics of a microelectronic substrate. The microelectronic substrate can have a first surface with first topographical features, such as roughness elements, and a second surface facing opposite from the first surface and having second topographical features, such as protruding conductive structures. In one embodiment, the apparatus can include a support member configured to carry the microelectronic substrate with a first portion of the first surface exposed and a second portion of the second surface exposed. The apparatus can further include a topographical feature detector positioned proximate to support member and aligned with the first portion of the first surface of the microelectronic substrate to detect characteristics, such as a roughness, of the first surface while the microelectronic substrate is carried by the support member.

Abstract: A traffic light system (10) with an impedance matching circuit (14) for electrically coupling an optical assembly (12) to a switched AC power supply (26) is described. The impedance matching circuit (14) has a matching transformer (20), a first resistor chain (22) and a second resistor chain (24). Each resistor chain (22,24) has an input and an output. Each of the inputs is common with a respective electrical node of the matching transformer (20). Each of the outputs is common with a respective supply node provided by the primary windings (18a) of an input transformer (18) of the optical assembly (12).
