VGA SoC image sensor integrates advanced ISP algorithms
Submitted by nestorb on Mon, 2006-09-25 22:42. This sensor integrates advanced image signal processing (ISP) algorithms and refined 2.6-micron pixel array, and delivers enhanced and sharper image quality in low light conditions. This can be attributed to functional features which have been incorporated and fortified in the pixels and the ISP engine embodied in the PO4030..
Understanding Inclinometers
Submitted by nestorb on Wed, 2005-09-28 07:14.An Inclinometer (or Clinometer) is an instrument for measuring angles of slope (or tilt), elevation or inclination of an object with respect to gravity. Also known as a tilt sensor, tilt indicator, slope meter, slope gauge, gradient meter, gradiometer, level gauge & level meter.
Understanding Piezoelectric Sensors
Submitted by nestorb on Thu, 2005-07-21 08:46. The piezoelectric effect was discovered by Jacques and Pierre Curie in 1880. They found that if certain crystals were subjected to mechanical strain, they became electrically polarized. Also these same materials deformed when exposed to an electric field. This is known as inverse piezoelectric effect.
Understanding pH measurements
Submitted by nestorb on Fri, 2005-07-08 00:06. pH is an abbreviation of “pondus hydrogenii” and was proposed by the Danish scientist S.P.L. Sørensen in 1909. pH provides the degree of activity of an acid or a base in terms of hydrogen ion activity.
The future of active FRId tags
Submitted by admin on Thu, 2005-07-07 15:47. I will not discuss every aspect of the probable evolution of RFId tags,
but to the new possibilities that you could imagine if you think in the
combination of RFId tags and wireless sensor networks.
