Abstract:
A process photometer which includes an insulated and a non-insulated compartment. The insulated compartment is maintained at a relatively constant, elevated temperature. The radiation source, a rotatable filter wheel, a radiation detector, and a means for converting analog output to a digital signal are among the components within the insulated compartment. The non-insulated compartment houses a power supply.
Abstract:
The present invention allows illumination light of a light source which leaks out to a light receiving element to be reliably shielded and allows components to be assembled to be unitized into a compact body. A light-shielding cylindrical section 31 and a light-shielding plate 32 interposed between a light-receiving side light guide 10 and a light emitting side light guide 11 are formed on a frame body 29 of a push button 2 as a single piece. Illumination light which leaks out from a light emitting element 6 and the light emitting side light guide 11 to a light receiving element 5 is shielded by the light-shielding cylindrical section 31 and the light-shielding plate 32. Support ribs 35 and a hook 41 for positioning a circuit substrate 7 are formed in the frame body 29, whereby the light guides 10, 11, light-shielding cylindrical section 31 and light-shielding plate 32 are unitized on the frame body 29.
Abstract:
A free-space optically-coupled collimator for the efficient bidirectional transmission of an optical metrology beam emanating from a waveguide aperture of a waveguide optical transmission element, all contained in an isothermal nested enclosure, with the waveguide element mounted in a stress-free fashion. The focus of the collimator is set at the waveguide aperture of the waveguide optical transmission element, the optical axis of the collimator aligns with the optical metrology beam as it exits the waveguide aperture of the waveguide optical transmission element, and the numeric aperture of the collimator is equal to or larger than the numeric aperture of the optical metrology beam as it exits the waveguide aperture of the waveguide optical transmission element.
Abstract:
The present invention is an accumulated light meter that generates data concerning the quantity of photosynthetically active radiation available over a measured period of time. The device can calculate a daily light integral (DLI) that corresponds to the amount of light required by certain plants in order to optimize photosynthesis. The device also possesses the ability to filter out the effect that wavelengths of unproductive light have on the calculated values since not all light is conducive to photosynthesis and different species of plants can utilize different wavelengths of light in dissimilar ways.
Abstract:
Infrared radiation from a plurality of locations associated with a process is measured by a field device, which includes a plurality of input channels, a plurality of IR sensors, and a data processor. The infrared radiation from the locations associated with the process is received by the input channels and the intensity of the infrared radiation is measured by the IR sensors to produce representative sensor signals. The data processor produces an output as a function of selected sensor signals.
Abstract:
A signal (Snormal) is provided to a heat element of a temperature sensor, which is recorded as a step response (Lruh, Lbew). From the difference of the step response compared with the reaction adaptively determined with the temperature sensor at zero air circulation, air flow or no air flow is determined.
Abstract:
A collector assembly with a radiation collector, a cover plate and a support member connecting the radiation collector to the cover plate are provided. The cover plate is designed to cover an opening in a collector chamber. The collector chamber opening may be large enough to pass the radiation collector and the support member. The removed radiation collector can be cleaned with different cleaning procedures, which may be performed in a cleaning device. Such cleaning device may for example consist of the following: a circumferential hull designed to provide an enclosure volume for circumferentially enclosing at least the radiation collector; an inlet configured to provide at least one of a cleaning gas and a cleaning liquid to the enclosure volume to clean at least said radiation collector; and an outlet configured to remove said at least one of said cleaning gas and said cleaning liquid from the enclosure volume.
