A three-stage four-dimensional encoding system and method for DMT-based transceivers includes a first stage where a parallel shifter shifts three bits of input data bits from a shadow register into a holding register. Next, a convolutional encoder generates encoded bits v1, v0, w1 and w0, using the three bits in the holding register. The encoded bits w1 and w0 may be registered as w1′ and w0′ for later use. In the second stage, the encoded bits v1 and v0 are provided to the inputs of the parallel shifter for parallel parsing of bits for the first tone of a pair of tones of DMT and the number of bits needed for the first tone are parallel shifted to the holding register. The bits in the holding register are then mapped by a constellation mapper into a constellation point. In the third stage, the encoded bits w1′ and w0′ are provided to the inputs of the parallel shifter for parallel parsing of bits for the second tone of the pair of tones and the number of bits needed for the second tone are parallel shifted to the holding register. The bits in the holding register are then mapped by a constellation mapper into a constellation point.

An office-type stationery set, which comprises a basic box seat to be placed on the desk, and an upright paper holder seat, to be covered with a cover made of transparent or enlarged-functional material, and connected with the rear wall of the basic box seat. The basic box seat includes a pen-stand seat, pen-stands, paper deposit box and paper dispensing device. The paper dispensing device is upright set on the lid of the paper deposit box comprising a button, a connecting rod, a pushing rod, and a pushing wheel. When the button is pressed, the driving rod will be oriented downwards and therefore push the connecting rod, to be responsive in movement to make the pushing rod which is pivoted on its front end, to move forward. The pushing wheel on the rear end of the pushing rod will not roll, as a ratchet is set to be an obstruction, but will rub on the paper and by frictional force push it out of the box. When the button is up, the spring within the paper dispensing device will return to a former state, and the pushing wheel on the front end of the pushing rod will roll back. In this way, it will not pull back the paper that is ready to be sent out. With the present invention it is possible by merely pressing the button, to send out one piece of paper will be sent out at the same time.

Leader devices usable with roll media and an image forming system having an output member are disclosed. A leader device may include a leader member having a first end and a second end. The first end may attach to the output member of the image forming system. The leader device may also include an attachment means disposed on the second end of the image forming system for removably attaching the leader member to a leading edge of the roll media.

A 5α-androstane-3β,5,6β-triol injection and its preparation are disclosed. The injection uses hydroxypropyl-β-cyclodextrin as a solubilizing agent and the active ingredient is present at a weight ratio of 1-20:40-500 to the hydroxypropyl-β-cyclodextrin. The injection may also comprise, by weight, 1-100 parts of at least one isotonic adjusting agent, 0-200 parts of at least one freeze drying filler, and 0-2000 parts of at least one solvent. The preparation method comprises dissolving hydroxypropyl-β-cyclodextrin solution, 5α-androstane-3β,5,6β-triol and at least one additional soluble excipient in water for injection in sequence to obtain a raw injection solution, and subjecting the raw injection solution to decolorization, depyrogenation, filtration and sterilization to obtain the injection, Drying the filtrate yields a solid for injection.

A method of modifying the amount of at least one biochemical component in a plant comprising expressing Qua-Quine Starch (QQS) in the plant, the wild-type of which does not express QQS; a transgenic plant, or part thereof, which comprises and expresses QQS as a transgene and in which the amount of at least one biochemical component is modified; a tissue culture of regenerable cells of the transgenic plant; a vector comprising a nucleotide sequence, which encodes the coding sequence of QQS, operably linked to a non-native promoter, which promotes expression of the nucleotide sequence in a plant, which is other than Arabidopsis; and a method of producing a food or industrial product from a plant.
摘要:
A method for storing information items from a client device to a remote server is performed at the client device having memory and one or more processors, the remote server being communicatively coupled to the client device. The client device renders an information item and an information storing option associated with the information item using a first application at the client device. Upon detecting a user selection of the information storing option, the client device invokes a second application, which may or may not run on the client device, to upload data associated with the information item rendered on the client device to the remote server and then resumes the rendition of the information item using the first application at the client device.

A multi-channel decoding method includes: receiving an input signal to generate a channel output signal; providing a first test signal serving as the input signal in a first calibration mode; and adjusting a DC voltage level of the channel output signal with a first calibration signal by reducing a difference between a first predetermined reference signal level and a DC voltage level of the channel output signal generated from the first test signal.
