A spectroscopic sensor for measuring flat sheet product is disclosed. The disclosed sensor uses a combination of spectrometers and single-channel detectors and filters together with a broadband source of illumination to optimally measure multiple properties of a flat sheet product. A spectrometer is used to measure over a spectral range where an easily configurable set of wavelength channels is needed and where the signal-to-noise ratios and spectral resolutions of the channels are consistent with the spectral range and number of pixels of the spectrometer; while one or more single channel detector and filter combinations are used to measure, with high signal-to-noise ratio, at specific wavelengths within or outside the spectral range of the spectrometer(s). Therefore, the single channel detectors can be used to complement the information provided by a spectrometer or to extend the working range of a spectrometer by providing single wavelength measurements anywhere in the visible, near-IR or mid-IR spectral regions.

A high-speed measuring electronic digital outside micrometer allowing a user to make measurements quickly and effectively compared to conventional electronic outside micrometers with rotary thread spindles, which have limited measuring speed. This high-speed measuring electronic digital outside micrometer features: a linear motion digital sensor, a linear scale digital sensor, a linear motion digital sensor base, a digital display unit, an electronic processing unit, a micrometer body, a linear spindle, a linear spindle movement unit, a spindle control unit, a micrometer anvil, and retractable springs. In a stationary position, the measuring surface of the micrometer anvil and the linear spindle are in contact to the other. By operating the spindle control unit, it will create distance between the micrometer anvil and the linear spindle measuring surface. This distance is a measurable distance of the micrometer. By set free of the spindle control unit, the retractable springs will re-set the micrometer to its stationary position.

The invention relates to a method for introducing and removing workpieces, especially vehicle bodies, into or from a treatment area (20) by rotational movements, whereby the treatment area serves for treating surfaces of the workpieces (1).

A method and a device for measuring, by means of radar, in an enclosed space (1) in which a liquid (2) is stored, the level of a liquid surface (6), where the method involves the steps: a radar unit (3) mounted on the roof (4) of the enclosed space transmits a microwave signal downwards into the enclosed space (1) through a waveguide (7) that communicates with the liquid in the enclosed space; the transmitted microwave signal's polarization alters according to a predetermined time sequence in such a way that the signal is propagated alternatively at least in a first and a second plane of polarization; the signal transmitted the first plane of polarization is reflected by the liquid surface (6) back to the radar unit (3); the signal in the second plane of polarization is reflected by at least one reference transmitter placed at a known distance from the radar unit; a calculating unit calculates the level of the liquid surface based partly on the propagation time for the microwave signal, i.e. for the time between the signals emitted and received by the radar unit, partly on the microwave signal's velocity of propagation, which is obtained from measurements in relation to the references.

Glaucoma is the second most common cause of blindness in the global world. It is a multifactorial disease with several risk factors, of which intraocular pressure (IOP) is the most important. IOP measurements are used for glaucoma diagnosis and patient monitoring. IOP has wide diurnal fluctuation, and is dependent on body posture, so the occasional measurements done by the eye care expert in clinic can be misleading. We provide an implantable sensor, based on microfluidic principles, which in one example has 1 mmHg limit of detection, high sensitivity and excellent reproducibility. This sensor has an optical interface, which enables IOP to be read with, for example, a cell phone camera. The design, fabrication, along with the option of self-monitoring are promising steps toward better patient care and treatment for this devastating disease.

A system and method of adjusting mask feature dimensions to compensate for anomalies in energy output of a laser beam used in ablating a workpiece. This method involves measuring the effects of variations in energy output of the laser beam at several points in the laser beam profile. In the case where the workpiece is a nozzle plate, the features adjusted in the mask are the diameters of the mask holes. Differences in the effects of the energy output between the points in the laser beam are then compensated for by adjusting the mask features that correspond to the points in the laser beam.
