|20090257126||ZERO-ORDER DIFFRACTIVE PIGMENTS - The present invention relates to pigments comprising or consisting of a layer made of a material with an index of refraction that is higher than the index of refraction of the adjacent material by at least 0.25; whereas said layer has a zero-order diffractive micro-structure; whereas said layer acts as an optical waveguide and whereas said layer has a thickness between 50 nm and 500 nm; to processes for its manufacture and to its use. These pigments show a colour effect upon rotation and/or tilting, and it is believed that this colour effect is based on zero-order diffraction.||10-15-2009|
|20090095986||PHOTO SENSOR WITH A LOW-NOISE PHOTO ELEMENT, SUB-LINEAR RESPONSE AND GLOBAL SHUTTER - A photo sensor exhibiting low noise, low smear, low dark current, high dynamic range and global shutter functionality consists either of a pinned (or buried) photodiode or a photo-sensitive charge-coupled device, each with associated transfer gate, a sub-linear element, a shutter transistor, a reset circuit and a read-out circuit. Using two output paths global shutter and high speed operation are possible for the linear and the sub-linear output of the sensor. Because of its compact size, the photo sensor can be employed in one- and two-dimensional image sensors, fabricated with industry-standard CMOS and CCD technologies.||04-16-2009|
|20080224054||Photon detection device - The present invention discloses a photon detection device that is adapted to detect at least one packet of photons. The photon detection device may include a photon-sensitive element having an output, an amplifier; and a non-linear feedback (NLF) element. The photon-sensitive element generates charges upon the engagement of at least one photon packet therewith. An increase from a first number of charges in the photon-sensitive element to a second number of charges, results in a corresponding increase of a first reset time required to reset the first number of charges to a respective second reset time required to reset the second number of charges in the photon-sensitive element, whereby the reset time is non-linear to with respect to an increase in the charges. Additional and alternative embodiments are described and claimed.||09-18-2008|
|20080223141||Pressure measurement device and system, and method for manufacturing and using the same - The present invention discloses a pressure measurement device comprising: a substrate that includes at least one pressure sensing module and at least one fluid-conductive channel, wherein each channel has a first aperture and a second aperture. The substrate is flexible such that the pressure measurement device is conformably adjustable onto an object's surface. The first aperture is located on the substrate such that when the substrate is suitably adjusted onto the object's surface, the first aperture is open to the exterior of the object's surface. The pressure sensors module is operatively connected to at least one of the second apertures, such that the at least one pressure sensing module is generally being subjected to the pressure being present at the first aperture.||09-18-2008|
