Patent number: 7274815Abstract: An apparatus is disclosed for generating a three-dimensional (3-D) image of a scene illuminated by a pulsed light source (e.g. a laser or light-emitting diode). The apparatus, referred to as a phase-sensitive 3-D imaging camera utilizes a two-dimensional (2-D) array of photodetectors to receive light that is reflected or scattered from the scene and processes an electrical output signal from each photodetector in the 2-D array in parallel using multiple modulators, each having inputs of the photodetector output signal and a reference signal, with the reference signal provided to each modulator having a different phase delay. The output from each modulator is provided to a computational unit which can be used to generate intensity and range information for use in generating a 3-D image of the scene. The 3-D camera is capable of generating a 3-D image using a single pulse of light, or alternately can be used to generate subsequent 3-D images with each additional pulse of light.Type: GrantFiled: October 9, 2003Date of Patent: September 25, 2007Assignees: Sandia Corporation, California Institute of TechnologyInventors: Colin L.

Patent number: 7274258Abstract: A dynamic bias circuit for an RF amplifier is provided to overcome the drawbacks of conventional bias circuits. The dynamic bias circuit of the present invention is best used for an RF amplifier having an FET amplifying transistor. It automatically raises the DC bias point as the input power increases. As a result, the saturation of output power in the pinch-off region can be avoided. This dynamic bias circuit not only improves the operating characteristics of the RF amplifier, such as high operating efficiency and high-linearity output power, but also consumes zero power in its internal circuitry. Furthermore, it has a simple circuit structure with very few circuit components and a reduced chip area. It can thus be easily integrated into an amplifier to achieve a cost reduction.Type: GrantFiled: September 8, 2005Date of Patent: September 25, 2007Assignee: Industrial Technology Research InstituteInventor: Chih Wei Wang

Patent number: 7274870Abstract: An apparatus and method for simultaneous channel and optical signal-to-noise ratio (OSNR) monitoring is adapted to function in multi-channel wavelength-division-multiplexed (WDM) optical communication systems. A polarization controller is sequentially adjusted to perform the sequential polarization control with an optical signal. A polarization-selective electro-optic modulator acts as a polarizer and provides a signal dithering to improve the detection sensitivity. A beam splitter splits the dithered optical signal into two clusters. A photodetector receives the first cluster and measures the OSNR. An optical element receives the second cluster and monitors the channel wavelength of multiple channels. The apparatus can be packaged into a compact module and integrated on a chip. The channel monitoring covers a wide wavelength range and is tunable. The OSNR monitoring can be accurate over a wide dynamic range.Type: GrantFiled: June 14, 2003Date of Patent: September 25, 2007Assignee: Industrial Technology Research InstituteInventors: San-Liang Lee, Chun-Liang Yang, Jui-Ting Wu, Ming-Hsiao Yang

Patent number: 7275002Abstract: An islanding detection and protection method of a parallel-type power converter is proposed, which performs perturbation to a power system to detect the frequency of the system voltage and the variation of the magnitude of the negative-sequence voltage as the basis for deciding the occurrence of an islanding operation. When the system operates normally, the frequency or phase and magnitude of the system voltage and the magnitude of the negative-sequence voltage won't be affected by the perturbation. On the other hand, if an islanding operation occurs, this perturbation will cause an apparent drift of the frequency or phase and magnitude of the system voltage and the magnitude of the negative-sequence voltage. Through detection of this apparent drift, the perturbation can be amplified by means of positive feedback to quickly detect the islanding operation phenomenon and trigger the protection mechanism.Type: GrantFiled: May 18, 2006Date of Patent: September 25, 2007Assignee: Industrial Technology Research InstituteInventors: Yung-Fu Huang, Pao-Chuan Lin, Tain-Syh Luor
