Abstract: Optical systems are provided. One such optical system includes an optical source that propagates a source beam of light. A diffracting component is optically coupled to the optical source and is operative to receive the source beam and produce a diffracted beam. A target is located to receive the diffracted beam. Additionally, a compensating system repositions at least one of the optical source, the diffracting component, and the target in response to a detected change in refractive index of a medium through which the diffracted beam propagates so that the diffracted beam continues to be received by the target. Methods and other systems also are provided.

Abstract: A method of and an apparatus for determining the individual existence of first and second groups of particles contained in a fluid and differing in characteristics from each other that are capable of, e.g., during an automatized ion exchange operation, individually distinguishing anionic and cationic ion-exchange resin particles and capable of easily monitoring their regeneration state. A plurality of beams comprising different wavelength bands are emitted from light-emitting elements, projected onto a subject of measurement containing first and second particles, and received by light-receiving elements, and the reflectivities of the beams are measured. When the ratio of the reflectivity of a first of the beams to that of a second of the beams is above a predetermined value, the subject of measurement is determined to contain particles of the first kind, whereas when that ratio in reflectivity is below the predetermined value, the subject of measurement is determined to contain particles of the second kind.

Abstract: A flexible gas sensor includes a housing with a predetermined form factor, a photoacoustic gas sensing chamber, and at least one of acoustic, temperature, relative humidity or pressure sensors in combination with processing circuitry which can emulate the characteristic gas response output of a catalytic bead pellistor-type gas sensor in response to a selected gas. The processing circuitry can include a programmable processor and a storage unit. The storage unit can be loaded with data and executable instructions to specify, at least in part, how the signals from the photoacoustic sensor are to be processed by the processing circuitry.

Abstract: An apparatus for determining a type of a recording medium is provided. A detection unit detects a characteristic value indicating a physical characteristic of a recording medium. A measurement unit measures a moisture content correlated with a moisture content of the recording medium. A determination unit determines the type of the recording medium based on the moisture content and the characteristic value. The determination unit may correct the characteristic value using the moisture content or correct a rule for determining the type of the recording medium using the moisture content unit, and determines the type of the recording medium in accordance with the corrected characteristic value or the corrected rule.
