Abstract: An infusion bottle monitor device has an electric circuit module, a sensing module, and a wire connected to the electric circuit module and the sensing module. The electric circuit module has a microprocessing system. The sensing module has a sensing system to output a sensing signal into the microprocessing system. A micromotion control system is disposed in the electric circuit module. A hose is connected to a hollow tube. The hollow tube is connected to an infusion bottle. The sensing module is disposed on the hollow tube. A plurality of clamp devices are disposed on a lateral of the electric circuit module. An opening is formed on the lateral of the electric circuit module. A support frame is disposed on the lateral of the electric circuit module pivotally.

Abstract: An illumination system having improved efficiency and uniformity for an image projection apparatus. The illumination system is employed for supplying an optical radiation beam along a principal axis to illuminate an object which, in a plane perpendicular to the principal axis, has a non-round cross-section. The illumination system includes: a light source for emitting light beams; a reflective mirror, having a plurality of reflective curved surfaces for reflecting the light beams emitted from the light source to form a plurality of reflective beams; and a lens plate, having a plurality of lenses, each of the plurality of lenses corresponding to a reflective curved surface of the reflective mirror to project the plurality of reflective beams onto the object, so that the plurality of reflective beams are superimposed on the object and produce a uniform illumination.

Abstract: A liquid-crystal projection display system with higher efficiency is provided. The liquid-crystal projection display system comprises a double-layer square-pillar-like integrator, including an inner layer and an outer layer, having a polarization-separating thin film formed between the inner layer and the outer layer. The system also includes a converging light source for generating light converged at a point near one end surface of the double-layer square-pillar-like integrator, so that most light emitted from the light source enters the double-layer square-pillar-like integrator, and different polarized light is transmitted by being totally reflected off of surfaces of the inner layer and the outer layer respectively. A first lens is provided for forming real light spots on an image plane from virtual light spots formed by totally reflecting the different polarized light transmitted in the double-layer square-pillar-like integrator.
