  • Patent number: 8946654
    Abstract: A method for reading out image information stored in a storage phosphor of a storage medium includes moving a light beam over the storage medium. A luminescence signal is generated by the photostimulation of the storage phosphor. In first time intervals a respective output value is determined from the luminescence signal, and a respective pixel value of an image pixel of a digital image is determined from the output value. The output value is thereby determined by addition of a plurality of measurement values of the luminescence signal which are detected in second time intervals lying within the first time interval. A corresponding apparatus for carrying out the method is described as well.

  • Patent number: 8872134
    Abstract: Described is a self-indicating instant radiation dosimeter (1001) for monitoring high energy radiations, such as X-ray. The dosimeter contains a radiation sensitive, color changing, indicating composition (10), e.g., a diacetylene (R—C?C—C?C—R?, where R and R? are substituents groups) or a radiochromic dye, a polymeric binder (20) and optionally a shelf life extender (50) or an activator (40). The radiation sensitive composition (10) changes color instantly when exposed to high energy radiation. The dose is estimated by comparing the color with a color reference chart or more accurately with a spectrophotometer or an optical densitometer. The radiation sensitive composition (10) is protected from low energy radiation such as UV light, by a layer of low energy absorbing materials, such as UV absorbers.

  • Patent number: 8866108
    Abstract: A vehicle microtagging system employs vehicle paint to assist in tracking vehicles used in criminal activity. Microscopic microtag particles mixed into vehicle paint contain unique alphanumeric code sequences. These particles are designed to be left behind at a crime scene, later to be recovered by law enforcement. When the microtag particles are recovered from a crime scene, law enforcement uses a simple UV light test and a magnification instrument to identify the unique alphanumeric code sequence within the microtag particles.
