摘要： A waste processing system includes a storage tank to collect urine, a dose pump to mix a volume of urine pretreat with a volume of water and dispense the resultant pretreat mixture into the storage tank, and a sensor configured to monitor one or more properties of the pretreat mixture. The sensor is an optical sensor transmitting a light signal through the pretreat mixture. A method of monitoring a flow of a pretreat mixture of a waste processing system includes mixing a volume of urine pretreat with a volume of water at a dose pump defining a pretreat mixture, directing the pretreat mixture along a fluid pathway toward a storage tank, and measuring one or more properties of the pretreat mixture via an optical sensor disposed along the fluid pathway.

摘要： Systems and methods are disclosed for detecting the concentrations of constituent gases in a sample. Systems may include a sample chamber configured to contain a volume of a gas, a light source configured to emit infrared light through the volume of the gas, a reference channel, a plurality of active channels, and processing circuitry. The reference channel and the active channels can each include a bandpass optical filter configured to receive light from the light source and selectively pass a portion of the light within a unique range of wavelengths, and a photodetector configured to detect infrared light from the light source that passes through the bandpass optical filter. The processing circuitry can be configured to calculate the concentrations within the sample gas of a plurality of constituent gases based at least in part on the light detected at each of the photodetectors.

摘要： To provide a concentration measuring method with which the concentration of a predetermined chemical component can be accurately, quickly, and nondestructively measured down to a concentration range of an extremely small amount with a simple means, and to provide a concentration measuring method with which the concentration of a chemical component in an object to be measured can be accurately and quickly measured down to a concentration range of a nano-order extremely small amount in real time, the method having universality, i.e., the ability to be embodied in various forms and modes. Light having a first wavelength and light having a second wavelength, which have different light absorptances with respect to an object to be measured, are each radiated onto the object to be measured using a time-sharing method; the light having the first wavelength and the light having the second wavelength, optically passing through the object to be measured as a result of the irradiation with the light having the first and second wavelengths, are received with a common light receiving sensor; a differential signal between a signal related to the light having the first wavelength and a signal related to the light having the second wavelength to be output from the light receiving sensor according to the received light is formed; and the concentration of a chemical component in the object to be measured is derived on the basis of the differential signal.

The plate-shaped member (40) is arranged so as to cover the light-emitting portion (10) and the light-receiving portions (20) that are mounted on the mounting substrate (30). Positions of the light-emitting portion (10), the light-receiving portions (20), and the plate-shaped member (40) are set such that, in the case where the analysis target is in contact with the plate-shaped member (40), light emitted from the light-emitting portion (10) is incident on two or more of the light-receiving portions (20) after being reflected or diffused by the analysis target.
