摘要:
The present invention relates to a method for purifying, modifying and immobilizing recombinant protein. The method utilizes genetic engineering to tag a DNA sequence encoding a target protein with a specific tag and express the vector to obtain a recombinant protein. The recombinant protein is then purified and modified by an affinity column and modification reagent. After exchanging the recombinant protein with a decoupling reagent, the recombinant protein is immobilized onto a specific substrate. The method, combining steps of purification, modification and immobilization, provides convenience to using recombinant protein. The omission of the use of dialysis or molecular sieve leads to a shorter period dedicating for removing excessive reagents and the increase of efficiency of recombinant protein recovery.

The invention discloses a method and device for image filtering in the field of communication technologies, the method including: acquiring image data of a pixel dot of a current row to be filtered and a corresponding pixel dot of at least one adjacent row; obtaining contrast information containing a transparency value, of the pixel dot of the current row and the pixel dot of the adjacent row respectively by resolving the image data of the pixel dot of the current row and the pixel dot of the adjacent row; generating a filter coefficient according to the transparency value of the pixel dot of the current row and the transparency value of the corresponding pixel dot of the adjacent row; and performing filtering on the pixel dot of the current row with the filter coefficient. The embodiments of the invention effectively avoid image flickering due to a difference between contrasts by adopting the method of at-least-two-row vertical filtering, and by generating the filter coefficients according to the transparencies in filtering.

A method of restoring a corrupted audio signal includes the steps of inputting the corrupted audio signal in a first channel, inputting one or more further correlated audio signals in one or more further channels, and restoring the corrupted audio signal using a Multi-Channel Autoregressive (AR) Model that models the corrupted signal as a linear combination of scaled time shifted portions of the further signal(s) and the corrupted signal. Embodiments are described in which the method is used to improve received audio signals in DAB receivers and mobile telephones.

A computer user interface for use in a transport vehicle (10), which defines a virtual control panel in the upper open area of the vehicle steering wheel (12). The user enters inputs by action in appropriate sections of the virtual control panel area. A computer controlled display (20) illustrates a map to the user of locations of sections in the virtual control panel area, and information that can be input by user action with particular sections. A sensor (22) monitors the virtual control panel area, and produces electronic information corresponding to user action in the virtual control panel area. Software logic in a computer (46) analyzes the electronic information to determine if there has been user action and the location thereof, for designating an action as a particular user input. Based upon the designation, the computer produces an appropriate output, such as operating or adjusting vehicle systems.

A method of a method of fabricating a contact. A substrate having a plurality of gates and a plurality of lightly doped source/drain regions is provided. A dielectric layer is formed and patterned to form a self-align contact window to expose a first lightly doped source/drain region of said lightly doped source/drain regions, and to form a first spacer on a side wall of a first gate of said gates simultaneously. An ion implantation is performed by using the first spacer as a mask, so that a first heavily doped source/drain region is formed in the first lightly doped source/drain region. A doped poly-silicon layer is formed over the substrate, and a metal silicide layer is formed on the doped poly-silicon layer. The doped poly-silicon and the metal silicide layer are patterned to form a self-align contact.

A method of restoring a corrupted audio signal comprises the steps of; inputting the corrupted audio signal in a first channel (30-32), inputting one or more further correlated audio signals in one or more further channels (33-35), and restoring the corrupted audio signal (36) using a Multi-Channel Autoregressive (AR) Model that models the corrupted signal as a linear combination of scaled time shifted portions of the further signal (s) and the corrupted signal. Embodiments are described in which the method is used to improve received audio signals in DAB receivers and mobile telephones.

A method for forming a metal oxide semiconductor field-effect transistor (MOSFET) includes forming a III-V compound semiconductor on a substrate with the III-V compound semiconductor being doped with a first dopant type. The method further includes doping a first and second region of the III-V compound semiconductor with a second dopant type to form a drain and a source of the MOSFET. The method further includes forming a gate dielectric on the III-V compound semiconductor through atomic layer deposition. The method further includes applying a metal onto the dielectric to form a gate of the MOSFET. A MOSFET is also disclosed herein.
摘要:
A scooter including a footboard, a rear wheel, a front wheel rod fastened to the front end of the footboard in conjunction with a folding member, a handlebar fastened to the top end of the front wheel rod, a wheel frame fastened to the bottom end of the front wheel rod, and a front wheel member fastened pivotally to the wheel frame and formed of three front wheels to stabilize the scooter in motion. Two of the three front wheels are in contact with the ground surface, with the remaining one front wheel being pivoted over the two front wheels such that the remaining one front wheel is capable of swiveling to come in contact with the ground surface at the time when one of the two front wheels encounters an obstacle. The folding member enables the front wheel rod to swivel toward the footboard so as to facilitate the storage or transportation of the scooter.
