Verfahren und Gerät zur Überwachung und Zielverfolgung

Light barrier e.g. for free-falling parts detector

The appts. comprises a rectangular frame of which two opposite sides hold light transmitter/receivers, the other two sides simply holding the frame together. As the parts fall within the frame they are optically monitored by the light-bearing arms. However, because the parts are falling freely, there is a risk of damage to the light transmitter/receivers. This can be reduced by mounting these light barriers of the light-coverings (13) at least partially under a protective shield (18a, 18b). This shield is formed by a shock-resistant surface (18b) and edge (18a) raised over the covering (13) above the lights (12), which are mounted in a u-shaped housing (7). A part falling towards the light barrier hits the protective shield and ricochets back instead of hitting and possibly damaging the optical system.

METAMATERIAL DEVICES AND METHODS OF USING THE SAME

Compressive imaging captures images in compressed form, where each sensor does not directly correspond with a pixel, as opposed to standard image capture techniques. This can lead to faster image capture rates due to lower I/O bandwidth requirements, and avoids the need for image compression hardware, as the image is captured in compressed form. Measuring the transformation of an emitted multimodal signal is one method of compressive imaging.
