  • Patent number: 11784579
    Abstract: A rectifier includes a first input and a second input that receive an unrectified signal, a first circuit portion including a first transistor coupled to the second input, a second circuit portion including a second transistor coupled to the first input, a third circuit portion including a third transistor coupled to the first input, a fourth circuit portion including a fourth transistor coupled to the second input. The first, second, third, and fourth circuit portions are operable to convert the unrectified signal into a rectified signal. The rectifier includes a first adjustment circuit coupled to a gate of the third transistor, and a second adjustment circuit coupled to a gate of the fourth transistor. The first adjustment circuit and the second adjustment circuit are configured to control a dead time between an on-state of the third transistor and an on-state of the fourth transistor.

  • Patent number: 9665676
    Abstract: An integrated circuit (IC) design system includes a processor; and a non-transitory computer readable medium connected to the processor. The non-transitory computer readable medium is configured to store a configuration file containing a custom IC design parameter, to store a process design kit (PDK) containing a default IC design parameter, and to store instructions for execution by the processor. The instructions for execution by the process include instructions for extracting the custom IC design parameter from the configuration file. The instructions for execution by the process further include instructions for overwriting the default IC design parameter in the PDK with the custom IC design parameter. The instructions for execution by the process further include instructions for creating an IC design file using a module in the PDK using the custom IC design parameter in place of the default IC design parameter.

  • Patent number: 8383961
    Abstract: An electromagnetic interference (EMI) shielding apparatus generally includes a lid and a framework. The lid includes a top portion having at least one projection joining part thereon. The at least one projection joining part has a peripheral contour. The framework includes a top portion and a lateral side extending downward from the top portion. The top portion includes at least one joining opening having a peripheral contour coinciding with the peripheral contour of the at least one projection joining part of the lid. Accordingly, the at least one projection joining part of the lid is engagable with the at least one joining opening of the framework via an interference fit.

  • Publication number: 20090281680
    Abstract: The present invention provides a method for simultaneously playing video frames and trip message, and the method includes the following steps: (a) receiving a trip video frame data; (b) decoding the trip video frame data to obtain a plurality of video frames and a plurality of trip message, wherein each of the trip message corresponds to one of the video frames; (c) simultaneously displaying at least one video frame and its corresponding trip message. When the user uses the method for playing the trip video frame data, the user can simultaneously see the video frame and its corresponding trip message, so as to achieve a good performance of monitoring.

  • Publication number: 20090276118
    Abstract: A method for processing trip information and dynamic data streams are provided, and includes the following steps. (1) A dynamic data stream including a plurality of video frames is received. (2) Plural batches of trip information are received. (3) At least one batch of trip information and at least one corresponding video frame of the dynamic data stream are taken to construct trip video data. Therefore, when a user playbacks the trip video data, the user can simultaneously see the video frame and obtain the corresponding trip information thereof.
