Abstract: An optical code scanner is presented that includes an improved user interface and an improved external computer interface. The user interface includes illumination devices that illuminate an air gap between the edges of a weigh plate and the top surface of the optical code scanner. The illumination devices provide guidance to the operator that allows the operator to optimize scanning performance. The external computer interface exposes controls that allow an external computer to determine what information is displayed to an operator.

Abstract: An apparatus, system and method are presented for improving the accessibility to self-service terminals by the visually impaired. An apparatus is provided that when attached to a touch-screen display improves accessibility. The apparatus includes touch identifiable symbols. A user operates a self-service terminal by selecting the appropriate symbol on the apparatus in response to audible instructions from the terminal.

Abstract: Standard mosaic geometries in modern imaging systems, such as a thermal imager, give rise to the fundamental limitation of creating undersampled images that are degraded by aliasing which is a distortion affecting spatial frequency components of the image that are higher than half the sampling frequency. A point target image can either cover one image sensing element and generate a strong single signal or cover up to four adjacent sensing elements which will produce much weaker signals and result in edges of a spread target being degraded by spurious registration. In order to minimize aliasing for a square sampling grid, improved geometries for the detector elements are used which reduce the number of dead zones associated with the current square geometries for the detector elements. One type of geometry for a detector element is a robigon having the form of a polygon obtained by substituting linear sides of a square by a triangular wave shaped edge.

Abstract: Methyl ketones are prepared in liquid phase by oxidizing terminal olefins of the formula R--CH.dbd.Ch.sub.2, where R is a hydrocarbon radical. The oxidizing agent is hydrogen peroxide or an organic hydroperoxide, and the catalyst is a palladium catalyst of the formula Pd AA' whereA is fluoborate, acetate or trifluoroacetate, andA' is OOR.sub.1 and where R.sub.1 is a hydrocarbon radical.
