Patent TW-200829906-A (TW)
Title: Polarizing film inspection device
Inventor: HU JIN-ZHE
IPC: G01N21/84
Filed: 2007-01-11
Abstract: The present invention relates to a polarizing film inspection device, comprising: a light source generator disposed at one side of the polarizing film, a polarizing unit, a beam splitter, and an optical inspection unit having an optical inspector and a spectrometer. The polarizing unit comprises a standard polarizer piece disposed between the light source generator and the polarizing film. The beam splitter comprises a light inlet for receiving the light passing through the polarizing film and two light outlets having spacing with the light inlet. One of the light outlets of the beam splitter is in connection with the optical inspector to measure the absorption axial angle of the polarizing film, and the other light outlet is in connection with the spectrometer to measure the chroma value, degree of polarization, and transmittance rate. Accordingly, this invention can measure a plurality of optical properties of the polarizing film and achieve advantages of reducing inspection time, convenient inspection operation and simple instrument setup.
Patent TW-200830586-A (TW)
Title: Light-emitting diode and packaging method and packaging device thereof
Inventor: Wang xiang-heng
IPC: H01L33/00
Filed: 2007-01-15
Abstract: Disclosed are a light-emitting diode and a packaging method and a packing device thereof. The light-emitting diode comprises a semi-finish product comprised of a base, a die, and pins. A rack that carries the semi-finish product is positioned in a bottom mold member that forms an accommodation chamber to have the semi-finish product received in the accommodation chamber. A shaping board forming a through hole is positioned on the bottom mold member to have the through hole corresponding in position to the accommodation chamber. A shaping mold member having a cavity that is open in a downward direction is positioned on the shaping board to have the cavity corresponding in position to the through hole. The shaping mold member also forms a flow passage that is set at one side of the cavity and a resin injection channel in communication with the flow passage. Liquid packaging material is put into the resin injection channel of the shaping mold member to have the liquid packaging material flow through the flow passage into and fills up the chamber, the through hole, and the cavity. Heat is then applied to the liquid packaging material to have the liquid packaging material cured and forming a lens. As such, the manufacturing efficient and operation reliability are enhanced.
Patent TW-200814598-A (TW)
Title: MIMO communication system and method for beamforming using polar-cap codebooks
Inventor: LI QING-HUA
IPC: H04L27/26
Filed: 2007-02-07
Abstract: Embodiments of a multiple-input multiple-output (MIN40) communication system and methods for beamforming using polar-cap codebooks are generally described herein. Other embodiments may be described and claimed. In some embodiments, beamforming is based on codewords of a polar-cap codebook which represents deviations in the channel with respect to codewords of a full-manifold codebook.
Patent TW-200833298-A (TW)
Title: Surgical positioning device
Inventor: YANG BEEN-DER
IPC: A61B6/12
Filed: 2007-02-09
Abstract: A surgical positioning device comprises a main part and at least three fiducial markers. Said fiducial markers have a CT number ranging from 1,000 to 3,000 and may produce dense, bright, and artifact-free spots on a CT scanning image.
Patent TW-200742277-A (TW)
Title: FM transmitter using switched capacitor filter
Inventor: SAGARA TAKESHI
IPC: H03L7/093
Filed: 2007-02-14
Abstract: The FM transmitter converts an input audio signal to a stereo composite signal, frequency-modulates the stereo composite signal and outputs the obtained signal. A stereo modulator stereo-modulates the output signal of the filter circuit, and converts the signal to the stereo composite signal. A frequency modulator frequency-modulates based on the stereo composite signal output from the stereo modulator. The filter circuit includes a pre-emphasis circuit, a low pass filter and the like, for example. At least one part of the filter circuit, that is, the low pass filter or the pre-emphasis circuit is configured with a switched capacitor filter.
