Abstract: A method of building a stereoscopic model with Kalman filtering (KF) is provided. The method entails capturing images of the environment with a sensing device to build the stereoscopic model and then correcting a static object and a dynamic object in the environmental images with Kalman filtering to enhance the accuracy of the stereoscopic model. The prior art is a great reduction of accuracy in simultaneous localization and mapping (SLAM) in the event of increased system variation, increased complexity, or increased involved field. The method overcomes a drawback of the prior art.

Abstract: A transformer structure includes a first conductive plate, a second conductive plate, a circuit board and a core assembly. The first conductive plate has a first through hole and two first pins, and the first pins are formed by bending two ends of the first conductive plate respectively. The second conductive plate is installed opposite to the first conductive plate and has a second through hole and two second pins, and second pins are formed by bending the two ends of the second conductive plate respectively. The circuit board includes a winding, a positioning portion and a third through hole. The core assembly is electromagnetically coupled to the first conductive plate, the circuit board and the second conductive plate and passed through the first, second and third through holes to provide a high amperage and low-profile transformer structure.

Abstract: A decoder and an operation method thereof are provided. The decoder includes a pre-unit, a database, a data filter, and a scheduler. The pre-unit provides packet information of a data stream. The database records a plurality of parameter sets. The scheduler fetches the corresponding parameter sets from the database according to the packet information, and saves the parameter sets into the data filter. The data filter compares the data stream with the saved parameter sets and outputs a comparing result. Therefore, the present invention reduces the cost of the decoder.

Abstract: An apparatus and a method for an efficient audio/video (AV) synchronization are provided. The apparatus includes a parser, a frame memory, a video start code (VSC) detector and a video decoder. The parser is used for analyzing a packetized elementary stream (PES) and outputting a video stream, an address information and at least one time stamp, in which the video stream includes a frame and at least one VSC corresponding to the frame. The frame memory is used for temporarily storing the video stream according to the address information. The VSC detector is used for retrieving the VSC of the video stream. The video decoder is used for selecting the frame from the frame memory according to the VSC and the address information provided by the VSC detector.

Abstract: A flexible length decoder including a plurality of data filter units and a control unit is provided. The data filter units perform a comparing operation on a data stream according its corresponding pattern and output a comparing result. The control unit controls the configurations of the data filter units. If the space of any one of the data filter units for storing the pattern is not enough to record the required pattern, the control unit combines two or more data filter units into an equivalent data filter unit, such that the equivalent data filter unit stores the pattern and performs the comparing operation.
