Abstract: A graphical near-field identification method and apparatus are provided. The method includes filtering a searched beacon signal according to a preset filtration condition. The method further includes matching a filtered beacon with beacons in all beacon graphs to obtain a beacon graph having a largest beacon matching number and the number of beacons matched with the beacon graph. The method further includes determining whether the number of the beacons matched with the beacon graph is less than a beacon determination minimum number requirement. The method further includes determining whether the number of the beacons matched with the beacon graph meets a beacon graph benchmark number condition. The method further includes determining that an object position is in a scenario where the beacon graph is located. The method further includes estimating a distance to the beacon by using a RSSI value of the beacon signal.

Abstract: The present invention provides a hydrobromide of methyl 3-[(4s)-8-bromo-1-methyl-6-(2-pyridyl)-4H-imidazol[1,2-a][1,4]benzodiazepine-4-yl] propionate and its related crystal forms, preparation method and use thereof. The hydrobromide has excellent solubility (>100 mg/ml), which is significantly superior to other currently commercially available or developed salt products, and is especially suitable for the preparation of injections, has relatively good stability in various crystal forms, and has good practical value and market prospects.

Abstract: An inverter includes a transformer configured to electrically connect an energy storage power source and generate induced ACs, first and second rectifier modules, first and second inverter modules, and first and second photovoltaic interfaces configured to receive DC from a photovoltaic module. The first and second rectifier modules are respectively electrically connected to the transformer and configured to convert the induced ACs into DCs. The first inverter module is electrically connected to the first rectifier module and the first photovoltaic interface for receiving the DC from the first rectifier module and the DC from the photovoltaic module, and converting the received DCs into an AC. The second inverter module is electrically connected to the second rectifier module and the second photovoltaic interface for receiving the DC from the second rectifier module and the DC from the photovoltaic module, and converting the received DC into AC.

Abstract: A system for generating an animated life story of a person is shown. The system may capture an image of the person's face and generate a computer-animated simulation of the person's face. The computer-animated simulation of the person's face may be superimposed upon a computer-generated based on personal historical data of the person so that a computer-generated life story of the person from an earlier period of time to the present may be generated as a movie or slideshow.
