Title: Analyte detection method in test, especially in body fluid
Inventor: DIETZE WERNER
IPC: G01N21/86
Filed: 1997-02-06
Abstract: The method involves using an analysis system (1) which includes analysis elements (3) and an evaluation device (2) for an instrumental evaluation of the analysis elements. An analysis result is indicated on a test field (6) of the analysis element through an indication (8) with a contrast against the background of the test field. The formation or change of the indication is detected by device of a detection unit (10), and is converted into electric signals which are processed by device of a processing unit (19) to provide an information about the presence of the analyte in the test. At least a part of the indication is displayed by an  imaging system (23) in an image plane (25), in which spatially separated photosensitive surface areas of two detectors (26,27) are located, which convert light hitting on the photosensitive surface areas into electric signals. The analysis element and the detection unit are moved relatively with respect to each other, so that the image of the indication meets successively both photosensitive surface areas of the detectors. The processing includes solving a function of the electric signals from both detectors.

Patent DE-19720864-A1 (DE)
Inventor: YIN XUEJUN DIPL ING
IPC: G01N3/42
Filed: 1997-05-06
Abstract: According to prior test procedures, the elastic characteristics of materials can only be determined in samples and not in real components. The invention enables the elasticity of a component to be determined directly on said component without causing any destruction. In order to determine the elasticity of a component (1) without causing any destruction (cf. Figure 6), a penetrating stamp (2) made from transparent material is pressed into the component (1) using a stressing device (7). Said stamp has known main curvature radiuses on both main curvature planes. A contact surface (3) is formed between the component (1) and the penetrating stamp (2) as a result of elastic deformation. The contact surface is illuminated with an optical system (4) and (6) through the transparent penetrating stamp. The dimensions of the contact surface are determined during stress by a longitudinal measuring system (5) and the normal force is determined using a force sensor (8). An elasticity value is determined from the normal force, the contact surface dimensions and the main curvature radiuses according to Hertz' equations. The invention is particularly suited for non-destructive determination of the elasticity of materials, specially real components in research and quality control.
