A device for fastening a measuring apparatus on pipes, in particular a butt weld seam checking measuring apparatus, containing a housing for accommodating the measuring, control, and/or drive units and a clamp, wherein the clamp is designed as a ring segment, wherein the clamp is attached in the radial direction over a pipe external diameter, wherein the clamp has a pre-tension in the installed state.

A fluorescence observation method includes a fluorescence imaging step of imaging fluorescence from an observation target by an imaging portion. The fluorescence imaging step includes a darkening step of darkening a space between the observation target and an observation window of the imaging portion by pressing a tip end portion of a light shielding member to the observation target or a placement surface of the observation target, in a state where a base end portion of the light shielding member including a tubular main body portion is attached to the imaging portion to surround the observation window, and a focus adjustment step of adjusting a focus position of the imaging portion.

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.

A system for identifying a biological sample in a sample holder. The system comprising a light source for emitting substantially monochrome light directed at the sample holder; a light sensor for detecting the amount of light reflected or transmitted by the biological sample and 5 configured to output measurements indicative of the amount of light detected; and a controller connected to the light sensor and configured to identify the biological sample based on the output measurements of the light sensor.

Parameters of an alcoholic or non-alcoholic beverage can be determined through spectroscopic methods. In one example, the method includes obtaining a beverage sample and obtaining spectrographic data from the beverage. The spectroscopic data may be processed by a remote lab to determine a value range of the one or more beverage parameters, and a value of the one or more beverage parameters. The one or more beverage parameters may include one or more of beverage color, bitterness, Free Amino Nitrogen (FAN), yeast count and yeast viability.

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.

Various embodiments of a light detection device and a method of using the device are disclosed. In one or more embodiments, the light detection device can include a housing that extends along a housing axis between top and bottom surfaces. The device can also include a port that is adapted to receive a sample, and a door connected to the housing. The door can include an actuator portion adapted to selectively move the door between a closed position and an open position, and a cover portion connected to the actuator portion and adapted to close the port when the door is in the closed position and open the port when the door is in the open position to allow external access to the port.

Apparatuses and methods of optically analyzing fluid within a pipette are described herein. In an embodiment, an optical reader subassembly includes a housing including an internal area, a container configured to hold a fluid sample at a sample position in a light tight manner within the internal area of the housing, a light source configured to project light onto the fluid sample within the container, and an optical sensor configured to move between different sensor positions while the fluid sample remains stationary at the sample position, the different sensor positions including at least two of: (i) a first sensor position for taking a luminescence reading of the fluid sample; (ii) a second sensor position for taking a dark current or other background measurement; and (iii) a third sensor position for taking a fluorescence reading of the fluid sample.

Apparatuses and methods of optically analyzing fluid within a pipette are described herein. In an embodiment, an optical reader subassembly includes a pipette configured to aspirate and hold a fluid sample within its tip, a housing configured to receive at least the tip of the pipette through a reentrant seal so that the tip of the pipette is located in a light tight manner within an internal area, a light source positioned to be in proximity to the tip of the pipette when the tip of the pipette is received by the housing, the light source configured to project light through the tip of the pipette and onto the fluid sample held within the tip, and an optical sensor configured to take a reading of the fluid sample held within the tip of the pipette without any of the fluid sample being injected from the pipette.
