    Abstract: In an apparatus for measuring the dimensions of an object, an opto-electronic sensor system includes an illumination device which sends light towards the object and a receiving device which receives light reflected from the object. In particular, the apparatus includes means for optically splitting the field of view of the opto-electronic sensor system into a plurality of sectors. Each of these sectors covers at least a partial view of the object under inspection from a unique viewing point. The arrangement of the optical splitting means is selected so that based on the respective field of view and the location of the actual or virtual viewing point of each sector the area on the object surface which is visible from at least one of said viewing points is maximized. The apparatus uses only one opto-electronic sensor, but obtains multi-perspective imaging of the object.

  • Patent number: 8507282
    Abstract: When assessing the start time of the limulus reaction between biogenous biologically active substances and LAL and using the reaction start time to determine the concentration of the biogenous biologically active substances, in order to exclude the influence of progressive changes which occur regardless of the conditions of the limulus reaction, the strength of transmitted light or scattered light in the liquid mixture of the measurement sample and LAL is detected, the variation (delta) in the transmittance or number of gel particles is acquired at set intervals, and the time when the variation (delta) crosses a threshold value is taken as the reaction start time. Furthermore, the time intervals when acquiring the abovementioned delta are not uniform, and either change over time from the start of measurement as defined by a time function, or multiple sequences with differing time intervals are prepared in advance.

  • Patent number: 8432549
    Abstract: A method of, and apparatus for, determining properties relating to multi-phase systems are provided. In the method, an array of sample tubes each containing a sample of a multi-phase system is formed. An iterative process is used to generate at least two data sets of transmitted and/or backscattered values for each sample and the data sets for each sample are processed to determine at least one property of the sample. The apparatus has a support on which an array of sample tubes each containing a sample of a multi-phase system may be assembled. It also has a wave source and at least one wave detector for detecting transmitted and/or backscattered values for each sample and computer means for iteratively operating said wave source and said at least one detector to generate data sets of transmitted and/or backscattered values for each sample and for processing the data sets for each sample to determine at least one property of the sample.

  • Publication number: 20130088716
    Abstract: Apparatus for detecting powder flow along a powder flow path includes a light source and a light detector for detecting light from the light source directed across the powder flow path as powder flows through said powder flow path. A circuit receives the output from the light detector and determines an average or RMS of the signal received by the light detector. The circuit may determine whether there is flow or no flow of powder or whether there is a change in flow rate of powder. Preferably, the apparatus is used in combination with a dense phase powder pump, which causes the powder to flow in pulses from the pump outlet into the powder flow path. More preferably, the light source and detector are enclosed in a housing that is connected between the pump outlet and a powder feed hose which supplies powder to a spray gun or hopper.

The specimen container is filled with a liquid sample to be tested and mixed with a reagent that provides a detectable parameter, and placed inside the apparatus. The incubation system heats and maintains the temperature of the liquid sample within a preset range while the spectrophotometer system propagates light within the specimen container, and monitors and records changes in the light as the light propagates through the container.

  • Publication number: 20130016355
    Abstract: A system and method for measuring particle concentration includes a communicative device, a main controller, a photon generator, and a photon sensor. The communicative device is in communication with the main controller. The main controller is in communication with the photon generator and the photon sensor respectively. In operation, the communicative device receives the input data from a user and transmits the input data to the main controller. The main controller decodes the input data. The main controller controls the photon generator to emit a particular type of light at particular intensity represented by the input data. The main controller controls the photon sensor to detect light. Upon detection, the photon sensor measures the amount of photon energy of the detected light and then transmits data representing that amount of photon energy to the main controller. The main controller transmits the data to the communicative device.
