Positioning instruments and related methods are described for implanting an energy absorbing system for treating joints. The positioning instruments and methods allow the energy absorbing system to be positioned at a joint such that the desired motion will occur for the particular design of a particular energy absorbing system which is to be implanted. The positioning instruments include a locating instrument for locating an anatomical feature and a target location for implantation of the energy absorbing system, a verification instrument for verification of the target location, a placement guide for guiding placement of a part of the energy absorbing system, and positioning device for aligning portions of the energy absorbing system.

An arrangement for measuring the diffuse reflection of samples and a method for internal recalibration of the measuring head. The spectrometric measuring head with a device for recalibration comprises a housing which is provided with a window and which contains an illumination source, a spectrometer arrangement and at least two standards for internal recalibration. The two standards can be swiveled into the beam path of the measuring head selectively so that the measurement light emitted by the illumination source can be used in its entirety for recalibration. A processor for acquiring and processing measured values and an interface to a bus system are arranged in the housing. Accordingly, relatively time-consuming calibration of the measuring head at the place of use is required only before putting into operation or at longer time intervals. By the internal recalibrations, it is possible to prevent changes in the measured values in long-term operation.

The present invention is directed to a fast, nondestructive measurement method for determining the contents of solid, liquid and/or suspended flowing organic compounds. The arrangement according to the invention comprises a sample vessel, a pump, and a measurement cell which form a unit together with a spectroscopic measurement head. The measurement cell is connected to the pump, which can be regulated to vary the flow rate, and to the sample vessel by a pipe, and the spectroscopic measurement head and the regulatable pump have electrical connections to a controlling and evaluating unit. Due to its compact construction, the solution which makes use of the principle of transflection is also particularly suited to mobile use, for example, to determine the components of liquid manure while the latter is being dispensed. In principle, the solution can be transferred to any applications with suspensions or pumpable, homogeneous and inhomogeneous materials.

A harvesting machine includes a measuring device for capturing the throughput of collected material. The measuring device has a measuring surface which acts together with the crop material and is supported movably at a support point in such a manner that its position depends on the throughput of the crop material, and an optical position capturing device for capturing the position of the measuring surface. Preferably the support point is a solid body articulation and the position capturing device is a laser interferometer.
摘要:
The description relates to a standard for wavelength and intensity for spectrometers, particularly for calibrating and testing measurement heads in spectrometers which are usable primarily in the near infrared region (NIR) of the spectrum. The standard comprises a holder and a plate body arranged in the holder. The plate body is made of transparent plastic with high strength and dimensional stability over a large temperature range. The plastic has distinct absorption bands throughout the entire NIR range and has a chemical structure and composition ensuring an extensive moisture barrier against water absorption and water release in a reliable and stable manner over time. The plate body advantageously comprises an amorphous, transparent copolymer based on cyclic and/or linear olefins.
