  • LUMINESCENT COMPOUNDS
    Publication number: 20130043406
    Abstract: A crystalline phosphor of formula: Lnx.(1?t1?t2?t3?t4)Ybx.t1Erx.t2Tmx.t3Hox.14BayZnzO1.5x+y+z in which: Ln is Y, Gd or La; t1+t2+t3+t4 varies from 0.001 to 0.3; and such that, when x=2, y=1 and z=1: t1+t3+t4 is nonzero; if Ln is La or Gd and if t3+t4 is zero, then t1 varies from 0.05 to 0.1 and t2 varies from 0.02 to 0.07; and if Ln is Gd, then t2+t4 is nonzero.

  • Vibrating wire viscosity sensor
    Patent number: 7574898
    Abstract: A method and apparatus for providing, e.g., identifying or determining, at least one parameter of a fluid moving through a fluid channel using a vibrating wire in contact with the fluid moving through the fluid channel that is clamped under tension. The vibrating wire is actuated by an actuating device capable of displacing the vibrating wire from an initial position. An interpretation element further is utilized to provide a parameter of the fluid moving through the fluid channel based upon data from the vibrating wire following actuation by the actuation element.

  • MICROFLUIDIC DOWNHOLE DENSITY AND VISCOSITY SENSOR
    Publication number: 20090120168
    Abstract: The present invention recited a method and apparatus for providing a parameter of a fluid within a fluid channel using a MEMS resonating element in contact with the fluid moving through the fluid channel. Additionally an actuating device associated with the MEMS resonating element is further provided, such that the actuating device can induce motion in the MEMS resonating element. In communication with the MEMS resonating element is an interpretation element capable of calculating a parameter of the fluid moving through the fluid channel based upon data from the MEMS resonating element upon actuation by the actuating device.
