Abstract: A process for making a decorated article is described. The process entails printing, using a high temperature ink, a design on a surface of transfer paper, and transferring the design by sublimation to the surface of a clear flat substrate to obtain a decorated substrate. The thus decorated surface is then placed in a mold and thermoplastic resin is injected to form an article. The placing of the decorated substrate in the mold is such that the surface carrying the design faces the inside of the mold. An additional embodiment entails forming the decorated substrate to attain a three dimensional decorated substrate prior to placing it in the mold.

Abstract: A disposable optical format for lancing the skin of a patient and harvesting blood to determine blood chemistries such as glucose level includes a housing with openings defining an optical path. A translucent hollow capillary tube with multiple planar sides and an end cleaved to a sharp edge is mounted in the housing. The sides of the tube are formed of an optical material such as fused silica. Significantly less pain, high probability of blood harvesting and improved overall test time are achieved with integrating the lance, harvest and analysis operation.
Abstract: A method of manufacturing a fluid collection apparatus having an integrated lance and reaction area. The method includes providing a sheet of material and then coating the sheet with a photoresist in a pattern on one side of the sheet. The pattern defines a lance and a reaction area. At least one side of the sheet is placed in a solvent. After corroding the sheet in areas not covered by the photoresist, the sheet is removed from the solvent and reveals an integrated lance and reaction area.
Abstract: The invention relates to novel natural product derivatives of the formula (I), to processes for their preparation, to pharmaceutical compositions comprising them and to their use in the treatment of disorders in humans or animals:
