  • Publication number: 20150268290
    Abstract: A method for on-line diagnosing gradually-changing fault of electronic current transformers comprises the following steps collecting output signals of electronic transformers of a whole transformer substation, calculating theoretical instantaneous values of the current at the tail ends of power transmission lines and on secondary sides of transformers at every moment, comparing the theoretical instantaneous values with the corresponding collected values, calculating residual errors of the electronic current transformers at the head and tail ends of each power transmission line and the primary and the secondary sides of each transformer respectively, judging whether gradually-changing fault occurs with the electronic current transformers by comparing the residual errors with preset threshold values, and simultaneously performing Kirchhoff detection by injecting current into a busbar to position a fault transformer.

  • Publication number: 20140301109
    Abstract: A light guide plate comprises a transparent light guide plate body; and a plurality of reflection sheets disposed inside the light guide plate body adjacent to a bottom surface of the light guide plate body, wherein a surface of the reflection sheet away from the bottom surface is configured as a reflection surface, regions of the light guide plate body except the reflection sheets are configured as light transmission regions, and the light transmission regions and the reflection sheets are alternately arranged. Since the reflection sheets are provided inside the light guide plate body, the reflection sheet reflects the light which is directed from the one surface and passes through the display panel, and prevents the light, which is directed from the other surface of the display apparatus, from passing through the display panel and interfering with the normal display of the one surface. In this way, the display apparatus can achieve the double-surface display.

  • Patent number: 8751378
    Abstract: A strategic default score is determined for an entity that characterizes a likelihood of the entity voluntarily electing to default on a loan. Data characterizing credit data and valuation data of an asset owned by the entity is received. Using the received data, the strategic default score is generated which characterizes a likelihood of the entity to voluntarily elect to default on the loan when the entity is capable of paying-off the loan. Provision (e.g., display, transmission, storage, etc.) of the strategic default score is then initiated. Related apparatus, systems, techniques and articles are also described.
