    Abstract: Chlorophyll fluorometry may be used for detecting toxins in a sample because of changes in micro algae. A portable lab on a chip (“LOAC”) based chlorophyll fluorometer may be used for toxin detection and environmental monitoring. In particular, the system may include a microfluidic pulse amplitude modulated (“PAM”) chlorophyll fluorometer. The LOAC PAM chlorophyll fluorometer may analyze microalgae and cyanobacteria that grow naturally in source drinking water.

    Abstract: The invention relates to a device for inspecting eggs for the presence of blood. The device comprises a light source in order to pass light at a first wavelength which is not selectively absorbed by blood and light at a second wavelength which is selectively absorbed by blood through an egg to be inspected. Furthermore, the device comprises detection means for converting the light transmission through the egg to be inspected for each of the two wavelengths into corresponding signals, each of the said signals being representative of the light transmission at the relevant wavelength. The device also comprises signal-processing means which are transmission associated with the first wavelength and the light transmission associated with the second wavelength based on the signals emanating from the detection means and to emit a decision signal which is representative of the decision whether or not an egg contains blood on the basis of this ratio. According to the invention, the light source comprises one or more identical LED's (Light Emitting Diode) for generating light which passes through the egg. In use the one or more LED's emit light within a certain narrow spectrum, which spectrum comprises both the first and the second wavelength.

    Abstract: An instrument and method for measuring light or color using modulated illumination. The system includes an LED illuminator modulated at a specific frequency for illuminating the sample, and a sensor capable of differentiating between the modulated light from the sample and unmodulated ambient light. The instrument is therefore capable of nullseeingnull only light from the sample, while ignoring ambient light. In a second embodiment, the system includes multiple illuminators of different colors each modulated at a unique frequency so that the sample can be measured at multiple at each of the different frequencies.
