  • Publication number: 20170025454
    Abstract: Structures and techniques introduced here enable the design and fabrication of photodetectors (PDs) and/or other electronic circuits using typical semiconductor device manufacturing technologies meanwhile reducing the adverse impacts on PDs performance. Examples of the various structures and techniques introduced here include, but not limited to, a pre-PD homogeneous wafer bonding technique, a pre-PD heterogeneous wafer bonding technique, a post-PD wafer bonding technique, their combinations, and a number of mirror equipped PD structures. With the introduced structures and techniques, it is possible to implement PDs using typical direct growth material epitaxy technology while reducing the adverse impact of the defect layer at the material interface caused by lattice mismatch.

  • Patent number: 8610760
    Abstract: A method for intensifying identification of three-dimensional objects identification includes utilizing a left eye camera and a right eye camera to capture a left eye image and a right eye image, calibrating the left eye image and the right eye image to generate a calibrated left eye image and a calibrated right eye image, using the calibrated left eye image and the calibrated right eye image to generate a disparity map, differentiating a three-dimensional object from a background image according to the disparity map, projecting the three-dimensional object onto a plan view, filtering noise out of the plan view to generate a filtered three-dimensional object, determining whether the filtered three-dimensional object contains at least two three-dimensional objects, and separating the at least two three-dimensional objects if the filtered three-dimensional object contains at least two three-dimensional objects.

  • Patent number: 8165325
    Abstract: An automotive virtual surround audio system is implemented in an automobile to receive left- and right-channel audio sources. A synthesizer receives the left- and right-channel audio sources to extend the sources into temporary rear-left and rear-right audio sources. A weighting device receives the left- and right-channel audio sources to perform a weighting operation and produce temporary front-left and front-right audio sources. A first filter receives the temporary front-left and front-right audio sources to perform a filtering operation and produce virtual front-left and front-right audio sources. A second filter receives the temporary rear-left and rear-right audio sources to perform a filtering operation and produce virtual rear-left and rear-right audio sources. Thus, the virtual audio image position is reproduced.

  • Patent number: 8121400
    Abstract: Comparison of parameters, including width, length, depth, color, and shape of a target object with a reference object is performed through use of a stereo camera. If the parameters of the target object are within threshold values of the parameters of the reference object, a match is indicated. If not, a new reference object is selected for comparison with the target object.

  • Patent number: 7270002
    Abstract: A humidity sensor element, a humidity sensor device and a method for manufacturing thereof are provided. The humidity sensor element includes a substrate having a nanocomposite film as sensing material, wherein said nanocomposite film consists of carbon nanotube/perfluorinated polymer with acid functional groups in weight ratio of 0.01-20; and at least a pair of electrodes, which contact with the sensing material at one or both side(s). The nanocomposite film increases the sensitivity of humidity sensor element such that even an infinitesimal amount of moisture can be detected with minimum detection limit of 15.76 ppmv.
