Abstract: A computer-controlled system for producing a multi-color image on a substrate using multi-colored cholesteric liquid crystal (CLC) pigment materials made from CLC flakes tuned to predetermined bands of color. An image generator automatically generates an image specifying a pattern over which binder material is to be applied to a substrate by a binder material applicator. A plurality of CLC pigment applicators automatically apply patterns of different-color CLC pigment material to the pattern of binder material, which binds thereto as the binder material dries according to its drying characteristics. An output device is used to automatically return the substrate to a different one of CLC pigment applicators after each application of a pattern of different-color CLC pigment material to the pattern of binder material. The output device automatically repeats the return of the substrate to the CLC pigment applicators until all bands of color in the multi-color image are rendered.

Abstract: A solid state transducer is provided for a Coriolis flow meter having a flow tube adapted to vibrate at a predetermined resonance frequency to determine mass flow rate of a fluid passing therethrough. The driver includes a strain element, such as an elongated piezoelectric or magnetostrictive element fastened axially along the wall of the tube. The strain element is adapted to oscillate in the axial direction along with the tube wall to generate and/or sense vibration of the tube in response to. The transducer may be utilized as a driver or alternatively, as a sensor wherein the transducer is oscillated along with oscillation of tube wall in the axial direction to generate an output signal responsive thereto.
