Abstract: A surface inspection system, as well as related components and methods, are provided. The surface inspection system includes a beam source subsystem, a beam scanning subsystem, a workpiece movement subsystem, an optical collection and detection subsystem, and a processing subsystem. The optical collection and detection system features, in the front quartersphere, a light channel assembly for collecting light reflected from the surface of the workpiece, and a front collector and wing collectors for collecting light scattered from the surface, to greatly improve the measurement capabilities of the system. The light channel assembly has a switchable edge exclusion mask and a reflected light detection system for improved detection of the reflected light.

Abstract: A surface inspection system, as well as related components and methods, are provided. The surface inspection system includes a beam source subsystem, a beam scanning subsystem, a workpiece movement subsystem, an optical collection and detection subsystem, and a processing subsystem. Certain of these components, most notably the beam source subsystem, the beam scanning subsystem and the optical collection and detection subsystem are modular for ready field replacement and/or maintenance. The optical collection and detection system features wing collectors in the front quartersphere and back collectors in the back quartersphere for collected light scattered from the surface of the workpiece. This can greatly improve the measurement capabilities of the system. Also included is a method for detecting asymmetric defects using the wing collectors and back collectors.

Abstract: Power management control software including power management policies is provided with those policies divided into observation code 18, 20, 22 and response code 26, 28, 30. When predetermined execution points 10, 12 within the operating system 2 are reached registered observation code 18, 20 for those execution points 10, 12 is triggered to be executed and serves to store event data within an event data store 24. At another time independent of the execution points 10, 12, the response code 26, 28, 30 is executed to read the event data from the event data store 24 and generate power control predictions and control signals therefrom.

Abstract: A surface inspection system, as well as related components and methods, are provided. The surface inspection system includes a beam source subsystem, a beam scanning subsystem, a workpiece movement subsystem, an optical collection and detection subsystem, and a processing subsystem. The system features masking positioned in the collection and detection subsystem arranged to selectively prevent a portion of scattered light from passing through. Also included is a scatter absorbing system having a series of scatter absorbing elements for minimizing unrelated to the scatter associated with a desired location on the surface.

Abstract: The invention relates to a novel polymer composition comprising at least one copolymer constituted of acrylic (AC) monomer units and of at least one water-soluble comonomer unit, which is preferably 2-acrylamido-2-methyl-propane sulfonic acid (AMPS). The composition is used to produce materials, such as membranes, film or suface coatings, that arc suitable as highly tissue compatible supports for epithelial cells, such as hepatocytes. The materials are suitable to be used in a bioartificial liver, where they work as separating membrane and carrier for adhesion-dependent tissue cells. As an example it is described how selectively permeable membranes are formed by a phase inversion process from these acrylic copolymers with varying content of 2-aclylanido-2-methylpropane sulfonic acid (AMPS) and how they interact with liver cells to construct a biohybrid organ for liver replacement.

Abstract: A data processing apparatus and a method of indicating operation of a data processor within a secure domain. The apparatus comprising a display for displaying data; a processor operable in a secure domain, said processor when operating in said secure domain having access to a user specific image; wherein said processor is operable to indicate operation within said secure domain by displaying said user specific image on at least a portion of said display when operating within said secure domain.

Abstract: An adsorbent material intended particularly for use in extracorporeal haemodialysis, is described which is composed of granules of an adsorbent which are coated with a biocompatible polymeric membrane which is semipermeable to the solutes selected for removal. The polymer is a copolymer containing carboxyl and amino groups. In use, solutes pass selectively through the membrane and are trapped by adsorption in the adsorbent thereby preventing or at least reducing the reverse process. To improve biocompatibility the product may be further coated with a plasma protein.
