Abstract:
A method for producing seed corn from the corn plants, for use in growing subsequent corn plants, includes measuring a moisture content of corn kernels on ears of the corn plants in the field and removing, by a combine harvester, the ears of corn from the corn plants when the moisture content satisfies a threshold moisture content. The method then includes separating the corn kernels from cobs of the ears of corn onboard the combine harvester and collecting the separated corn kernels for use as seed corn, whereby one or more subsequent corn plants can be grown from the collected corn kernels.
Abstract:
A method and apparatus for measuring the absorption characteristics of complex lenses to light from a selected band of wavelengths, preferably wavelengths in the ultraviolet range, is disclosed. Light from an incandescent light source is passed through a tunable interference filter, which passes light having only wavelengths from the selected band of wavelengths, and is directed toward a first side of a lens to be tested. An integrating light detector, preferably a selenium solar cell is placed in close proximity to the second side of the lens to be tested, and senses substantially the total amount of light flux passing through the lens, regardless of the lens' complexity and light diverging characteristics. The output of the detector is fed through amplifier circuitry to a suitable indicating meter. A light impervious housing structure may be provided to prevent ambient light from impinging on the detector. The device utilizes inexpensive elements, is very accurate, may be hand held, and is simple to use.
Abstract:
Combine harvesters are provided for use in harvesting seed corn from corn plants in fields. In connection therewith, a method for producing such seed corn from the corn plants, for use in growing subsequent corn plants, includes measuring a moisture content of corn kernels on ears of the corn plants in the field and removing, by one of the combine harvesters, the ears of corn from the corn plants when the moisture content satisfies a threshold moisture content. The method then includes separating the corn kernels from cobs of the ears of corn onboard the combine harvester and collecting the separated corn kernels for use as seed corn, whereby one or more subsequent corn plants can be grown from the collected corn kernels.
Abstract:
Provided is a portable ultraviolet device for exploring a mineral resource. The portable ultraviolet device for exploring the mineral resource may include a body, a visible component, an ultraviolet lamp assembly, and a darkroom component. The visible component is coupled to the body to pass through the body so that a mineral resource disposed at a lower portion of the body is observed from an upper side of the body. The ultraviolet lamp assembly part is coupled to the body to emit ultraviolet rays onto the mineral resource. The darkroom component is coupled to a bottom surface of the body to surround the visible component and the ultraviolet lamp assembly and defines an external light blocking space having an openable inlet in a lower portion of the body.
Abstract:
The present invention is a mold pathogen detection apparatus in which an agar strip is exposed to the environment being tested for a period of time and then exposed to a non-UV light to determine the amount of light passing through the agar strip.
Abstract:
An injection system for use with a luminometer, which includes a carrier movable between a liquid loading station and a liquid dispensing station and a dispenser assembly mounted on the carrier and including an injector needle arranged, when at the liquid loading station, to pass through an aperture in a part of the luminometer aligned with a test sample container therein, the container being in a test chamber with which a photomultiplier device communicates. The system also includes a sealing arrangement which prevents light from passing through the aperture in the luminometer, both when the needle extends through the aperture and when the needle has been withdrawn from the aperture.
Abstract:
Various embodiments of a light detection device and a method of using such device are disclosed. In one or more embodiments, the light detection device can include a housing including a top surface and a bottom surface, where the housing extends along a housing axis between the top surface and the bottom surface; and a support member connected to the housing and adapted to be selectively moved from a closed position to an open position. The support member is further adapted to maintain the light detection device in an upright position when the bottom surface and the support member are in contact with a working surface and the support member is in the open position.
Abstract:
The invention relates to a single-use detector of aromatic compounds, with:—a first part (20) comprising a light conversion layer (26), and a photosensitive layer (28) in one piece with the light conversion layer, to be capable of being exposed by exposure light (54) capable of being produced by the light conversion layer in response to excitation light (50), the light conversion layer containing an imprinted polymer precursor (32), capable of combining with a target aromatic compound to form a dye (34) that converts the excitation light into exposure light in a wavelength domain different from that of the exposure light and,—a second part (40) of developer, capable of being applied temporarily to the photosensitive layer (28) of the first part (20) to demonstrate a possible exposure of the photosensitive layer. Application to the detection of explosives.
Abstract:
A sensor mounting system having a suction cup array is disclosed. In one application, the system eases the initial positioning of the calorimeter on the screen to be measured, minimizes the force applied to the screen upon which it is mounted, and minimizes the distortion in the mounted area of the screen surface. In addition, the mounting system can be configured so that the distance from the colorimeter sensor to the screen will not significantly change over time. Such positional stability operates to improve SNR. The mounting system is further adapted for ease of removal from the screen upon which it is mounted. Applications not only include a mount for low to high accuracy calorimeters, but also for other measurement devices that can benefit from advantages of the present invention. Injection molding manufacturing techniques can be employed in fabrication of the system.
Abstract:
The dispersion photometer described is designed particularly for the kinetic determination of total proteins and has a light source (20), an optical system, a removable optical cell (24) in the sample chamber, a stirrer, a photo-electric sensor (38) which receives light scattered forward at an angle, and an electronic processing and display unit (46) connected in series with the photo-electric sensor (38). All the elements located between the light source (20) and the optical cell (24), and between the optical cell (24) and the photo-electric sensor (38), have a coefficient of transmission or reflection in the visible region of the spectrum which is as high as possible, and do not reflect or absorb selectively.
