The invention relates to the field of optical fiber communication, discloses a three-dimensional orthogonal frequency-division multiplexing data modulation method and a data demodulation method, and aims to solve the technical problem of incapability of lowering signal PAPR (Peak to Average Power Ratio) under the condition of not influencing other performances of a system in the prior art. The method comprises the following specific steps: performing three-dimensional data constellation points mapping on a bit sequence to be transmitted to obtain an orthogonal frequency-division multiplexing (OFDM) signal based on three-dimensional mapping; performing three-path overlapping on the real parts and imaginary parts of a plurality of time domain signals obtained after performing three-dimensional inverse discrete Fourier transform (3D-IDFT) on a three-dimensional OFDM symbol respectively through a three-dimensional CAP orthogonal filter, and combining to obtain final transmission time domain data; acquiring data to be transmitted through the time domain signal of a 3D-CAP-OFDM system and transmitting the data to be transmitted. By adopting the methods, the technical effect of effectively lowering the signal PAPR under the condition of no influencing the other performance of the communication system is achieved.

This invention concerns a biochip kit, comprising at least one biochip with at least one reactor, in which probe antibody and probe antigen are immobilized non-randomly in the form of probes array or / and probes pattern. This invention also concerns a method for testing a biological sample by using the kit. This kit can be used to analyze different target molecules corresponding to said probe antibody and probe antigen. By using this kit, the reactor number and the detection time needed for the analysis are reduced while the detection comparability is increased. So this kit has the advantage of being economical, timesaving and more efficient.

A method for the non-invasive measurement of the gas content of at least one gas selected from O2, CO2, amines, nitrogen oxides, sulfur compounds, in transparent packages made of plastic films, glass or other light-permeable materials, in which a sensor material sensitive to the gas content in the interior of the package is excited by excitation light incident thereon to emit a fluorescent or luminescent light, the emitted fluorescent or luminescent light is detected in a detection device interacting with the sensor, whereupon the packaged materials or produced materials are subjected to sorting, and optionally counting, as a function of the gas content determined by an evaluation unit coupled to the detection device, comprising the steps of:a) optionally deep-drawing the package;b) applying a sensor material to the inner side of a cover for the package, or to the inner side of the package, and optionally drying the sensor material;c) introducing into the package the materials to be packaged;d) gas-tightly closing the package by the cover while introducing a modified atmosphere of the gas to be measured;e) placing the package on a conveying and sorting device;f) exciting the sensor material by at least one excitation light source arranged at a defined distance from the package;g) detecting, in a contactless manner, the intensity of the fluorescent or luminescent light emitted by the sensor material as a function of the gas content in the interior of the package, by a detection device arranged at a defined distance from the conveying device during conveying of the package to the sorting device;h) electrically or electronically converting in the evaluation unit a measurement value detected in the detection device;i) optionally applying a pressure to the package, and performing steps t) to h) again;j) outputting a confirmation signal or a rejection signal by the evaluation unit; andk) forwarding the package to further processing or disposal as a function of the gas content in the package calculated by the evaluation unit, and a device therefore.

The invention discloses a cotton opening method capable of graded opening to improve product quality. The cotton bale is opened once, and the method includes the following steps: (1) The cotton blocks after one opening are graded through a grading net Screening; (2) Collect the cotton blocks on the grading net for secondary opening; (3) Combine the cotton blocks after the second opening with the cotton blocks under the grading net in step (1); (4) Step ( 3) Repeat steps (1)~(3) for the middle cotton block to perform the second graded cotton opening process. First of all, after the cotton block is fed, it is loosened by opening once, and then the size of the cotton block is graded by using a grading net, and the large-sized cotton block is opened for the second time, and finally the cotton block is uniformly transported to the discharge port. This method can make the large-sized cotton block be opened twice during the cotton opening process to further loosen it, and the small-sized cotton block can also avoid the secondary opening together with the large-sized cotton block, which will cause cracking. Too much cotton.

A glove dispenser is disclosed that permits sanitary donning of gloves by a user without the user touching the exterior of the glove during the donning process. The disclosed apparatus includes a plurality of glove attachment areas configured on a platform that allows disposable and non-disposable gloves to be releaseably attached to it by their cuffs, and present the inside of the glove cuffs to a user for easy sanitary donning. As such, a user may open the glove by pulling on the inner portion of the cuff with one hand, inserting the other hand into the opened glove, releasing the pulled cuff, and simply detaching the donned glove from the dispenser. Furthermore, the invention provides a new method for holding and donning gloves of various sizes, materials, construction, etc. while preventing a user from touching the exterior of the gloves, thus preventing contamination of the gloves.
