The reflecting part has a curve shaped reflecting surface that is configured to reflect light emitted by the light-emitting part. The light-receiving part is configured to receive incident light that is emitted by the light-emitting part and reflected at a detection site of a user. The protecting part is configured to protect the light-emitting part, and the protecting part haw a contact surface adapted to contact with the detection site. The processing part is configured to process a light-receiving signal outputted from the light-receiving part. The light-emitting part has a light-emitting surface substantially in parallel to the contact surface, and a distance between the light-emitting surface and the contact surface is within a range of 0.4 mm to 0.9 mm.

Abstract: The invention relates to a device (1) and a method for measuring the moisture in die cast molds (24), the cavity (25) of which is connected via an evacuation conduit (31) to an evacuation device (28). The modular assembly of the device (1) is connectable to the evacuation conduit (31) and comprises a sensor assembly (S) by means of which the moisture of gases evacuated from the mold cavity (25) is measurable. The sensor assembly (S) comprises an emitter (7) emitting electromagnetic radiation and a detector (14) detecting electromagnetic radiation. On the basis of the measured values obtained during the evacuation action it can be determined whether the amount of a water/release agent mixture jetted into the mold cavity (25) needs to be altered before the actual casting action.

Abstract: Optical computing devices are disclosed. One optical computing device includes an electromagnetic radiation source that emits electromagnetic radiation into an optical train to optically interact with a sample and at least one integrated computational element, the sample being configured to generate optically interacted radiation. A sampling window is arranged adjacent the sample and configured to allow transmission of the electromagnetic radiation therethrough and has one or more surfaces that generate one or more stray signals. A first focal lens is arranged to receive the optically interacted radiation and the one or more stray signals and generate a primary focal point from the optically interacted radiation. A structural element defines a spatial aperture aligned with the primary focal point such that the optically interacted radiation is able to pass therethrough while transmission of the one or more stray signals is substantially blocked by the structural element.

Abstract: System and method for detecting and counting bacteria suspended in a biological fluid by means of light scattering measurements is provided. In accordance with the method of the invention the level of signal to noise of the measured intensities of light scattered by a sample of the biological fluid is significantly enhanced for forwardly scattered light within a range of scattering angles which are smaller compared to a predefined maximal scattering angle. The system of the invention includes a cuvette adapted to contain a sample of the biological fluid whose sidewalls and windows are suitably constructed and arranged to significantly reduce the level of reflected light obscuring the scattering patterns measured within the range of scattering angles considered.

Abstract: A miniature readhead for a photometric diagnostic instrument includes a housing of hand-held form factor, configured for receiving reagent sample media therein. The sample media has a plurality of test areas configured to react with, and change color, according to an amount of an analyte in a sample. The holder is sized and shaped for forming an indexed fit with the sample media and includes an array of light sources coupled to the housing, each of the light sources configured to emit light onto a respective one of the test areas. An array of chambers respectively containing an array of light detectors, is configured to enable each of the light detectors to receive diffuse, non-specular reflections of the light from the test areas, while substantially preventing the light detectors from receiving specular reflections of the light.
