    Abstract: A method and apparatus is provided for determining a property of an analyte using a sensing layer whose optical response changes with the analyte. The apparatus includes a housing with an optically transparent window for receiving the sensing layer. The window passes optical stimulation to the sensing layer and the optical response from the sensing layer. A stimulating light emitter is coupled to a first face of an optical body monolithically coupled to the window and a light detector is coupled to a second face of the optical body for receiving the response. The optical response changes as the concentration of the analyte changes. Reference molecules included in the sensing layer can provide a calibration signal to a second light detector mounted on a third face of the optical body. The first, second and third faces of the optical body are different and not coplanar.

    Abstract: PURPOSE: A fire sensing unit is provided to prevent wrong operation due to a noise component, since there is no need to separate the signal line from a base board. CONSTITUTION: A device substrate(31) is installed in an optical case(21) and has a receiving element unit(12). The device substrate is connected to a signal line(35) which is communicated with an inlet of a main wall of the optical case. The opening unit of the optical case is closed by the optical cover. The signal line is inserted into a slit(37) which is opened in the upper end face of the main wall.

    Abstract: A method of analyzing a sample is disclosed. The method includes the steps of measuring a spectral response of the sample, selecting a reference material having a Raman peak with a magnitude at a wave number, measuring a peak value in the spectral response at the wave number, and determining an amount of the reference material in the sample based in part on a ratio of the measured peak value to the magnitude of the Raman peak of the reference material.

    Abstract: An optical sensor device (1) for a fluid substance (LS) comprises a device body (2) having a detection portion (14), associated to which is a sensitive optical part that comprises at least one of an emitter (20) and a receiver (21) of an optical radiation (Re, Rr). The detection portion (14) is made of a material transparent to the optical radiation (Re, Rr) and has an inner surface (23a, 23b) and an outer surface (15), the outer surface (15) being designed to be in contact with the fluid substance (LS) and the inner surface (23a, 23b) being designed to be isolated from the fluid substance. The at least one of the emitter (20) and the receiver (21) of the sensitive optical part is optically coupled to the inner surface (23a, 23b) of the detection portion (14), in such a way that the optical radiation (Re, Rr) is at least in part propagated through the detection portion (14), in particular with an angle and/or an intensity that is variable as a function of a characteristic of the fluid substance. The optical sensor device (1) comprises a protection arrangement, configured for preventing possible deformation of the detection portion (14) caused by an increase in volume of the fluid substance (LS), in particular deformation of at least one of its inner surface (23a, 23b) and its outer surface (15). The protection arrangement comprises at least one compensation element (13) having an elastically deformable body, which is able to contract, for compensating thereby a possible increase in volume of the fluid substance (LS) or else for enabling a reversible displacement of the detection portion (14) following upon a possible increase in volume of the fluid substance (LS).

    Abstract: A luminometer (400) includes a light detector (630) configured to sense photons (135). The luminometer (400) includes an analog circuit (915a) configured to provide an analog signal (965) based on the photons (135) emitted from assay reactions over a time period and a counter circuit (915b) configured to provide a photon count (970) based on the photons (135) emitted from the assay reactions over the time period. The luminometer (400) includes a luminometer controller (905) configured to, in response to an analog signal value of the analog signal (965) being greater than a predetermined value, determine and report a measurement value of the photons (135) emitted from the assay reactions over the time period based on the analog signal value of the analog signal (965) and a linear function (1010). Optionally, the linear function (1010) is derived from a relationship between the analog signal (965) and the photon count (970).
