Near InfraRed NIR technology, including NIR cameras and detectors, is used to accurately determine the strength of the green veneer sheet or other wood product. Based on the determined strength for a given green veneer sheet or other wood product, one or more actions are taken with respect to green veneer sheet or other wood product to ensure the green veneer sheet or other wood product is put the most efficient, effective, and valuable use.

A moisture detecting apparatus includes: a light emitting unit including a first light source configured to emit light having a first wavelength as a peak wavelength, and a second light source configured to emit light having a second wavelength as a peak wavelength; a detecting unit configured to detect a first detection value indicating an extent to which the light emitted from the first light source is transmitted through a recording material, and a second detection value indicating an extent to which the light emitted by the second light source is transmitted through the recording material, based on a light receiving result of a light receiving unit; and a determination unit configured to determine a value related to a moisture content of the recording material based on the first detection value and the second detection value.

An apparatus includes a chassis configured to move back and forth along multiple rails. The apparatus also includes electrical contacts configured to form electrical connections to the rails. The apparatus further includes a power converter/conditioner configured to receive power from the rails via the electrical contacts and to convert the power into a different form and/or condition the power. In addition, the apparatus includes one or more sensors configured to measure at least one characteristic of a material, where the one or more sensors are configured to operate using the power from the power converter/conditioner. The electrical contacts could touch the rails and receive the power directly from the rails. The electrical contacts could also touch rail contacts and receive the power indirectly from the rails via the rail contacts.

A first light emitter emits light toward a sheet. A first light receiver receives first reflected light from the sheet. A second light emitter is arranged downstream of the first light emitter in a conveyance direction of the sheet and emits light toward the sheet. A second light receiver receives second reflected light from the sheet. A measuring section measures first and second received light quantities of the first reflected light and the second reflected light. A moisture content calculator calculates a change in a moisture content of the ink in the sheet based on a difference between first and second moisture contents. The first moisture content is based on the first received light quantity and the second moisture content is based on the second received light quantity. A curling amount calculator calculates a curling amount of the sheet based on the change in the moisture content.

A web manufacturing supervision system for monitoring properties of a web being transported in a moving direction during a web manufacturing process, includes: a) a radiation source for illuminating a first spot on the web; b) a tunable first detector for capturing signal radiation emanating from the first spot within a signal wavelength band; the signal wavelength band being adjustable to one of at least a first wavelength band and a second wavelength band; c) a second detector for capturing reference radiation emanating from the first spot within a reference wavelength band; d) control means for alternatingly tuning the signal wavelength band to the first wavelength band and the second wavelength band and measuring the signal at both wavelength bands simultaneously.

A holder for drying includes a first member including a first tubular portion that protrudes like a tube and an annular second member that can fix filter paper in a flat state under tension by being fitted over the filter paper to surround an outer side of the first tubular portion while the filter paper is carried on the first tubular portion.
