86 results about "Number units" patented technology

The unit number is, in simplest terms, the basis upon which all other numbers are defined. In the real numbers (and all number systems contained within the reals), this unit is 1. All integer numbers are merely multiples of 1.

3-bit transmission type electromagnetic code metamaterial applied in terahertz band

InactiveCN106410422AConcise and effective analysisSimple and effective designAntennasOptical elementsPolyimide dielectricUnit structure
The present invention provides a 3-bit transmission type electromagnetic code metamaterial applied in a terahertz band. A basic unit structure is formed by the alternative arrangement of three layers of metal opening resonant ring structures and four layers of polyimide dielectric layers. Through the optimization design of the geometric parameter of an opening resonant ring structure, each unit can show eight independent refraction phases under the irradiation of a y polarization vertical incident electromagnetic wave, and the eight independent refraction phases are corresponding to number states '0' to '7'. According to digital codes designed in advance, number units are arranged on a two-dimensional plane, and the 3-bit transmission type electromagnetic code metamaterial is formed. In the terahertz band, the 3-bit transmission type electromagnetic code metamaterial can refract the incident electromagnetic wave, and the abnormal refraction is realized. Due to the excellent mechanical and chemical performance of the polyimide dielectric, the3-bit transmission type electromagnetic code metamaterial has the advantages of flexibility, corrosion resistance and physical wear resistance and has a wide application prospect in the aspects of terahertz imaging and communication.

Video-assisted radiofrequency positioning method and apparatus

The invention discloses a video-assisted radiofrequency positioning method and apparatus which assist radiofrequency positioning by using video positioning in order to achieve high-precision indoor positioning. The radiofrequency positioning apparatus comprises signal transmitters and a signal receiver. A signal link is formed between each signal transmitter and the signal receiver. An indoor space required to be positioned is divided into a plurality of unit grids. The indoor unit grids are positioned according to the RSSI value change of each signal link and a fingerprint matching algorithm. The radiofrequency positioning achieves indoor positioning and mobile monitoring functions. The video positioning determines a number unit where a current positioner is located, determines the movement of an object mainly by using a frame difference method, and is specifically implemented by designing a calibrator. The calibrator updates the information of a radiofrequency fingerprint database in real time in order to assist an increase in the radiofrequency positioning precision. The video-assisted radiofrequency positioning method and apparatus achieve purposes of long positioning time, high precision, low energy consumption, saving of resources, and decrease in personal privacy violation.

Method for reducing sulfur content in gasoline

A method for reducing sulfur content in gasoline comprises the following steps of: (1) contact-reacting a sulfur-containing light fraction gasoline with an ionic liquid at a temperature not less than the boiling point of the sulfur-containing light fraction gasoline and not larger than 200 DEG C, and condensing the gas-phase product to separate the gas-phase product from the liquid-phase product, thus obtaining a light fraction gasoline with reduced sulfur content; and (2) mixing the light fraction gasoline with reduced sulfur content with a sulfur-containing heavy fraction gasoline. The method provided by the invention can, on one hand, reduce the addition level of the ionic liquid and, on the other hand, reduce the yield of liquid-phase product (i.e. the loss of gasoline fraction) on the premise of ensured desulfurization effect. Particularly, most of light fraction gasoline with reduced sulfur content can be obtained without distillation. The gasoline obtained by mixing the light fraction gasoline with reduced sulfur content after contact reaction with the heavy fraction gasoline with reduced sulfur content obtained by hydrodesulfurization has reduced octane number by a magnitude within two octane number units and high desulfurization rate larger than 90% in comparison with the gasoline before desulfurization, so that the gasoline product can meet the EUROIII emission standard of automobile gasoline.
