Abstract: Apparatus (10), systems and methods are disclosed for treating a biological fluid with light. A container (206) of biological fluid is introduced into a fluid treatment chamber (40) where it is contacted with light provided by one or more light sources (60, 70) in proximity to the fluid treatment chamber (40). A light sensing system (650) senses the intensity of illumination of the light. A radiometer (460) may be inserted into fluid treatment chamber (40) to calibrate the light sensing system (650). An electronic control system (600) utilizes an interface circuit board (606) to interface a computer circuit board (602) to a display panel (37), a user interface panel (39, 39a), a relay circuit board (640), light sensors 404 and various other sensors (649). A detector (385) senses agitating movement of a tray (90) that contains biological fluids. Methods include calibrating (781-785), sensing (770-773) and correcting (774-775) light intensity measurements, and determining the length of treatment (776) to reach a desired illumination dose. A radiometer (460) is equipped with a plurality of light sensors (469) disposed on both sides to measure light intensity in chamber (40) and to provide a reference for calibrating light sensing system (650).

Abstract: The invention is a UV sensitive composition that undergoes a color change upon exposure to a predetermined dosage of UV-C radiation. The UV-C sensitive composition comprises a halogenated polymer, such as polyvinylidene chloride, that produces an acid upon exposure to UV radiation, and a pH sensitive dye. Upon exposure to UV-C radiation, the halogenated polymer undergoes degradation and produces HCl. The pH sensitive dye changes color as a result in an increase in HCl in the system. The composition may also include an acid scavenging composition and/or a diluent to control the amount of HCl produced in the system. The amount of HCl liberated from UV-C exposure may be selectively controlled so that a color change may be produced at a desired UV-C dosage. In some embodiments, the composition may be used to indicate a UV-C dosage from about 100 to 1600 mJ/cm2.

Abstract: The present invention discloses a method for measuring an intensity of a part of an electromagnetic spectral range, and an electronic device implementing the method. The method comprises the steps of providing an electronic device comprising an optical device (10) comprising at least a first liquid (A) and being placed in front of a sensor (120), the optical device (10) having a transmittance of the part of the electromagnetic spectral range depending on an orientation of at least the first liquid (A); measuring a first intensity of the electromagnetic (EM) spectral range; changing the orientation of at least the first liquid (A); measuring a second intensity of the electromagnetic spectral range; and calculating an intensity of the part of the electromagnetic spectral range from the difference between the first intensity and the second intensity. Consequently, an intensity for a part of the EM spectral range can be measured without the need for a sensor dedicated to this part of the EM spectral range. In particular, an optical element based on the electrowetting principle is used in a mobile phone to measure the intensity of UV radiation.

Abstract: In a conventional ultraviolet sensing device using a diamond semiconductor in a light-receiving unit, an Au-based electrode material is used for both a rectifier electrode and an ohmic electrode. However, the Au-based electrode material has fatal defects, such as poor adhesion to diamond, low mechanical strength, and furthermore poor thermal stability.While avoiding complication of the device structure and exploiting the characteristics of a photoconductive sensing device, by using a carbide compound (TiC, ZrC, HfC, VC, NbC, TaC, CrC, MoC, and WC) of a high melting metal having a high mechanical strength for a rectifier electrode and/or a ohmic electrode, there is provided an extremely heat-stable diamond ultraviolet sensor having a light-receiving sensitivity to ultraviolet light having a wavelength of 260 nm or less.

Abstract: A nuclear radiation detection system using narrowband UV crystal filters is disclosed. Since the photons produced during the decay of β- and γ-radiation can be detected in the spectral range of about 200-350 nm (the ultraviolet range), UV filter based photo sensors are utilized for detection. The nuclear radiation detection system comprises an optical assembly capable of focusing on a source of radiation, a UV filter assembly having a narrowband UV crystal filter and positioned to receive light transmitted through the optical assembly, and a light detector positioned to receive light transmitted through the UV filter assembly. The narrowband UV crystal filter is fabricated from crystals selected from the group consisting of nickel fluorosilicate, nickel fluoroborate, and potassium nickel sulfate. The nickel fluorosilicate, nickel fluoroborate, and potassium nickel sulfate may be doped to achieve even narrower band filter. The radiation detection system can be used to monitor contamination in a nuclear plant or a nuclear waste dump site. It may also be used for surveillance of contamination in case of a nuclear accident.

Abstract: A multidirectional ultraviolet sensor includes a substrate and a UV-sensitive layer. The UV-sensitive layer contains nano-sized or micro-sized particles of a UV-sensitive material, which is attached to a top surface of the substrate by sintering process to enable sensing of ultraviolet light incident on the ultraviolet sensor from various directions. The UV-sensitive layer is in contact with a first and a second electrode layer, which are arranged at the top surface or the bottom surface the UV-sensitive layer in the same horizontal plane, or respectively at two opposite sides of the UV-sensitive layer. Since an impedance value of the UV-sensitive layer changes in response to an intensity of incident ultraviolet light, the intensity of the incident ultraviolet light is measured by detecting the impedance of the UV-sensitive layer.
