Abstract:
A tire pressure warning assembly includes a tire valve with a switch received therein, which had a conductive member, a movable member and a biasing member. The movable member is located at a distance from the conductive member and one end of the movable member is exposed to the air in the valve and the other end of the movable member is in contact with the biasing member, which exerts a force to the movable member. The tire pressure compresses the biasing member. When the tire pressure is less than the biasing force of the biasing member, the biasing member pushes the movable member to contact the conductive member to form a circuit so that the warning device sends a signal to the driver.

Abstract:
In an interleaved bridgeless power factor corrector and a controlling method thereof, the interleaved bridgeless power factor corrector includes an AC input power supply, two input inductors, four active components, two passive components, an output capacitor, and an output resistor, wherein the four active components are cascaded in a full bridge form to act as control switches and rectifying switches having different phases; besides, the interleaved bridgeless power factor corrector is connected to a control signal processor and a control circuit, which can output complementary switch signals to control the interleaved bridgeless power factor corrector, thereby achieving output/input ripple cancellation and frequency multiplication.
Abstract:
A system of scattering surface plasmon resonance for detecting a target is disclosed. The system of scattering surface plasmon resonance includes: a base slide having a metal layer and a plurality of insulating nano-particles thereon, wherein said plurality of insulating nano-particles are dispersed on the surface of said metal layer for binding or coupling at least one detecting probe capable of binding or hybridizing said target; a light source providing an incident light to said base slide for inducing or exciting a surface plasmon resonance (SPR) signal; and a detector for receiving said SPR signal. The disclosed system can improve the adherence between the traditional slides and the probe molecules, enhances the scattering to increase the sensitivity of SPW detection, and facilitate and simplify the sample preparation for SPR.
