20150199940 | POWER MANAGEMENT METHOD AND DISPLAY DEVICE THEREOF - A power management method a display device utilizes the same are disclosed. The power management method, adopted by the display device, includes: increasing, by a control circuit, brightness of a lighting device, wherein the lighting device is configured to illuminate a display panel device; detecting, by an overload detection circuit, whether an overload has been triggered by the increased brightness; and when the overload has been triggered by the increased brightness, recording, by a power capacity determination circuit, a maximal predetermined brightness that is used prior to the overload is triggered, while showing an on-screen-display (OSD) warning message on a display of the display device for reminding the user. When the brightness of the lighting device reaches the maximal predetermined brightness and the power capacity determination circuit detects no overload, this indicates the power capacity is sufficient for supplying power to the display device. | 07-16-2015 |

20150021499 | CONVERTING INFRARED LIGHT INTO BROADBAND VISIBLE LIGHT AT HIGH EFFICIENCY USING LANTHANIDE-SENSITIZED OXIDES - The present invention includes upconversion materials such as lanthanide-sensitized oxides that are useful for converting low-energy photons into high-energy photons. Because silicon-based solar cells have an intrinsic optical band-gap of 1.1 eV, low-energy photons having a wavelength longer than 1100 nm, e g., infrared photons, cannot be absorbed by the solar cell and used for photovoltaic energy conversion. Only those photons that have an energy equal to or greater than the solar cell's band gap, e.g., visible photons, can be absorbed and used for photovoltaic energy conversion. The oxides described herein transform photons having an energy less than the energy of a solar cell's band gap into photons having an energy equal to or greater than the energy of the band gap. When these oxides are incorporated into a solar cell, they provide more photons for photovoltaic energy conversion than otherwise would be available in their absence. Nearly 10% of the infrared photons incident on these oxides are upconverted into visible photons. This upconversion efficiency is more than twice as large as the upconversion efficiency for NaYF | 01-22-2015 |

20150348704 | 0.2Ss class special-type high-voltage measuring current transformer - 0.2Ss class special-type high-voltage measuring current transformer belongs to a field of current transformer. An iron core includes two kinds of “L”-shaped sheets with the same size, wherein a ratio of a long side to a short side of each “L”-shaped sheet is 3:2; a first kind of the “L”-shaped sheets are permalloy sheets (1) and a second kind of the “L”-shaped sheets are cold rolled silicon steel sheets (2); and required windings are wound on each side of the iron core. Sheets of the iron core of the current transformer include the permalloy sheets and the cold rolled silicon steel sheets, which improves performance of the iron core. Utilizing structural characteristics of the iron core of different materials, a fractional turn compensation of coils is formed, which realizes a precise measurement. | 12-03-2015 |
