摘要： A particulate matter-sensing sensor assembly may include a housing in which an air flow passage through which air flowed thereinto from the outside thereof flows is formed, a fan motor internally disposed within the housing for flowing air into the air flow passage from the outside, a light source emitting light to allow light to intersect with air flowing into the air flow passage, and a light receiving sensor configured to receive light scattered by dust contained in air passing through the air flow passage, wherein the air flow passage is configured such that a region where air flows thereinto from the outside thereof has a cross-sectional area greater than that of a region where light emitted from the light source intersects with flowing air.

摘要： A housing (20) has a passage port (3) that serves as both the outlet for the illumination light (IL) to go out of the housing (20) toward a sample surface (S) and the inlet for the reflection light (RL) reflected on the sample surface (S) to enter the housing (20). A transparent member (19) is disposed at the passage port (3) to prevent dust including paper dust from entering the housing (20). A light quantity calculation unit (71) calculates the light quantity of light received by a light reception lens (33). A notification unit (81) performs a predetermined notification when the light quantity is less than or equal to a predetermined value.

摘要： An apparatus for checking mechanical parts such as tools on machine tools employs optical devices for emitting and receiving a light beam, for example a laser beam, along a checking direction, and sensors for detecting variations in the features of such a light beam. A protection device (15) for at least one of the optical devices comprises a support element (21,22) with an inner seat (20), communication conduits (18,26,34) aligned along the checking direction and a shutter (44) movable, in the internal seat, from a rest position to an operative position of the apparatus. The shutter comprises a transversal through hole (60) which is arranged along the checking direction in the operative position, aligned with the communication conduits to allow the light beam to pass through. A movable closure element (55), for example a small sphere or ball, is arranged in a transversal hollow (54) of the shutter and is pushed by a spring towards the outside of the transversal hollow. In the rest position of the apparatus, the transversal hollow is arranged along the checking direction and the movable closing element partially protrudes and cooperates with a gasket at the inlet of one of the communication conduits, to prevent the entry of foreign material and fluids into the optical device.

摘要： During an assay, optical measurements are made at a sensing surface (112), and at least one “homogeneity-image” of the sensing surface (112) is generated. From this image, an “homogeneity-indicator” is determined for at least one region of interest, and the optical measurements are then evaluated in dependence on said indicator. The homogeneity-indicator may for example be a binary value which indicates if an inhomogeneity was detected or not. If an inhomogeneity was detected, all optical measurements may be rejected, only measurements for the involved region of interest may be rejected, or measurements for a selected sub-area of the involved region of interest (ROI) may be rejected.

摘要： An efficient absorption spectroscopy system is provided. The spectroscopy system may be configured to measure solid, liquid or gaseous samples. Vacuum ultra-violet wavelengths may be utilized. Some of the disclosed techniques can be used for detecting the presence of trace concentrations of gaseous species. A preferable gas flow cell is disclosed. Some of the disclosed techniques may be used with a gas chromatography system so as to detect and identify species eluted from the column. Some of the disclosed techniques may be used in conjunction with an electrospray interface and a liquid chromatography system so as to detect and identify gas phase ions of macromolecules produced from solution. Some of the disclosed techniques may be used to characterize chemical reactions. Some of the disclosed techniques may be used in conjunction with an ultra short-path length sample cell to measure liquids.

摘要： A combination, handheld device for holding and loading/unloading a sample cell with a fluid sample, while the device is in a vertical orientation, is provided. The handheld device has a sample cell holder for selectively, removably holding the sample cell when the sample cell is in need of being filled with a fluid for testing in the polarimeter or is in need of being emptied of a fluid already tested in the polarimeter, and a sample cell fluid loader/unloader connected to and extending from, or unitarily formed with, the holder, the loader/unloader in fluid communication with the sample cell when the sample cell is held in the holder. Methods of loading and unloading a sample cell with a fluid sample using a combination, handheld device, are also provided.

摘要： A water quality sensor includes a housing including a light transmissive bucket mounted in an electrical washing appliance and a light transmissive inner barrel mounted in the bucket, an actuation module mounted in the inner barrel for detecting a water quality of a washing solution in the electrical washing appliance. Thus, if the bucket is cracked during manufacturing or due to a collision, the contact actuation module can still be well protected by the inner barrel, so that the washing solution in the electrical washing machine does not directly flow into contact with the actuation module to cause an accidental short circuit of the circuit substrate of the actuation module, improving the water resistance and service life of the water quality sensor.
