  • Publication number: 20200110267
    Abstract: An optical display system includes an information display (image-generating) component, a polarization dependent image offset optical element and possibly also a polarization rotator. By controlling the image offset optical element either by direct applying voltage or by controlling the polarization of the displayed light through the polarization rotator, the display pixels can be switched by a certain portion. By switching between offset and non-offset state with appropriate image displayed, the resolution as observed by the users can be enhanced.

  • Patent number: 9362745
    Abstract: A power storage module and a power storage device are disclosed. The power storage module and the power storage device include a DC/AC converter, a first power storage element, a second power storage element and at least one DC/DC converter. The first power storage element is coupled to the DC side of the DC/AC converter to form a first power storage branch. The second power storage element is coupled to the DC side of the DC/AC converter to form a second power storage branch. The DC/DC converter is disposed on the first power storage branch or the second power storage branch.

  • Patent number: 8804383
    Abstract: A starter of the grid-connected inverter and a control method thereof are disclosed. The starter comprises a controller, and a first switch and a first resistor connected in parallel. The controller includes an input end, and first and second output ends. The input end inspects the DC voltage signal from the inverter. When the DC voltage exceeds a predetermined voltage threshold, the first output end sends a first control signal to turn on the first switch, and the second output end sends a second control signal to make the grid-connected inverter enter into a chopping mode. There is a delay period between the send time of the first control signal and that of the second control signal.

  • Publication number: 20120124102
    Abstract: Systems and methods for loading XML documents on demand are described. The system provides a Wrapper class for the XML Document class and the Element class. A user application then utilizes the Wrapper class in the same way that the Element class and Document class would be used to access any element in the XML Document. The Wrapper class loads external components as required. The external component retrieval is completely transparent to the user application and the user application is able to access the entire XML document as if it were completely loaded into a DOM object in memory. Accordingly, each element is accessible in a random manner. In one configuration, the XML document components or external components are stored in a database in a BLOB field as a Digital Document. The system uses external components to efficiently use resources as compared to systems using Xlink and external entities.
