Abstract: The present disclosure provides methods and systems for recommending pick-up points. The method may include obtaining information of a searched point of interest determined by a user; determining a first set of candidate pick-up points based at least on the information of the searched point of interest, the first set of candidate pick-up points including a plurality of candidate pick-up points; determining at least one recommended pick-up point through a preset algorithm based at least on the first set of candidate pick-up points, and displaying the at least one recommended pick-up point to the user.

Abstract: Provides is a method for denitration of carbothermally reduced iron-containing nonferrous metal smelting slag mixed with advanced oxidizer. In the method, the iron-containing smelting slag is subjected to carbothermal reduction, such that metals or metal oxides in the smelting slag are reduced and transformed into active catalysts which could activate hydrogen peroxide to generate free radicals. Hydrogen peroxide is catalytically decomposed, generating ·OH free radicals, and ·OH free radicals generated further oxidize NOx.

Abstract: A projection device includes a front cover, a back cover, a projection lens, a processor, and an electromagnetic touch panel for handwriting input. The electromagnetic touch panel is provided on the inside surface of the front cover and in electrical connection and communication with the processor. When the users writes directly on the front cover or on a writing sheet held by a paper holder on the front cover, the electromagnetic touch panel senses the handwriting, converts it into a writing signal and transmits the writing signal to the projection lens for the handwriting to be displayed on a screen. The projection may further include a capacitive touch panel with a silkscreen printing keypad on one side thereof for the user to key in text. The projection device effectively saves time and space in making presentations or text editing.

Abstract: The dual input device has a keyboard on the front side of the input device, a display screen on the back side of the input device, an electromagnetic touch panel and a control circuit between the front side and the display screen. The keyboard, the display screen, and the electromagnetic touch panel are connected with the control circuit, respectively. The control circuit includes a direction control circuit for controlling the On/Off of the keyboard, the display screen and the electromagnetic touch panel. Through the direction control circuit, the input device combines the traditional keyboard and the writing pad in a single dual input device. In addition, because the electromagnetic touch panel is placed behind the display screen, the input data can be displayed in real time, and the original handwriting can be saved.

Abstract: Provided is a method of detecting method of detecting fusion transcripts in a sample to be analyzed.
