  • Publication number: 20080145537
    Abstract: A micro patch coating device includes a coating die with a micro channel structure. A coating fluid is supplied through a coating fluid inlet and an auxiliary fluid is supplied through an auxiliary fluid inlet. After a segment of a predetermined length of the coating fluid is formed at a two-phase fluid output section, the coating fluid flow is intercepted. In turn, a segment of predetermined length of the auxiliary fluid is formed at the two-phase fluid output section, and then the auxiliary fluid flow is intercepted. A two-phase fluid is formed and flows out of the coating die to the substrate to form micro patches thereon.

  • Publication number: 20080108900
    Abstract: An ultrasound transducer apparatus for shaping the ultrasound coverage field per application requirement in both the radiating and receiving mode of operation. Wave coverage field is shaped by forming at least one cut at designated location on the housing wall. A cut on the housing wall of the transducer pot-shaped structural body results into the reduction of wave intensity, either radiating or receiving, toward that direction where the cut is located.

  • Publication number: 20080002556
    Abstract: The present invention provides an optical head with a single or multiple sub-wavelength light beams, which can be used in arenas such as photolithography, optical storage, optical microscopy, to name a few. The present invention includes a transparent substrate, a thin film, and a surface structure with sub-wavelength surface profile. The incident light transmits through the transparent substrate, forms a surface plasma wave along the sub-wavelength aperture located within the thin film, and finally re-emits through spatial coupling with the sub-wavelength profile of the surface structure. As the coupled re-emitting light beam or light beams can maintain the waist less than that of the diffraction limit for a few micrometers out of the surface with sub-wavelength profile in many cases, this invention can have applications ranging from micro or nano manufacturing, metrology, and manipulation by using light beams with waist smaller than the diffraction limit.

  • Patent number: 7271914
    Abstract: A biomolecular sensor system utilizing a transverse propagation wave of surface plasmon resonance (SPR) is described. The system comprises: a substrate; a dielectric layer, having a groove therein and standing on top of the substrate; a sensing film layer, sitting at the groove; a pair of prism devices, each resting on one side of the groove and both separating a tunable distance. Besides, the sensor system further comprises a light source, a light detector (a frontend of which connecting to a spectrometer and a backend connecting to a differential amplifier) and a channel with a cover forming inside the groove for the acquisition of the reflected light from the prism devices. Since the sensor system is constructed by exploiting the SPR technique on the transverse propagation, a whole contact surface is under detection (parallel detection) which differentiates it from the traditional method of single-area SPR detection.
