摘要:
One or more techniques and/or systems are disclosed for rendering online ads on a webpage. A first inter-frame communication channel is created, which comprises a first communication channel between a first cross-domain frame and a host page, such as the webpage. The first cross-domain frame comprises content from a domain that is different than that of the host page domain. A second inter-frame communication channel is created comprising a second communication channel between the first cross-domain frame and a second cross-domain frame in the host page.
摘要:
Disclosed herein is a recombinant Escherichia coli (E. coli) capable of producing D-xylonic acid from D-xylose and a method for producing D-xylonic acid using the same. The recombinant E. coli producing D-xylonic acid from D-xylose according to the present invention is a recombinant E. coli EWX4 (Microorganism deposition number KCTC11988BP) capable of producing D-xylonic acid from D-xylose. When utilizing the recombinant E. coli prepared by the method of the present invention, it is possible to produce D-xylonic acid from D-xylose with high yield while reducing production cost using sole carbon source.
摘要:
The obstacle detecting system includes a first image acquiring unit which acquires first image information by selectively receiving a laser beam emitted from at least one laser source toward a road surface at a target distance; a second image acquiring unit which acquires an image of actual surroundings as second image information; an image recognizing unit which recognizes an image of an obstacle by performing 3-D image recognition signal processing on line information of the laser beam using the first image information, and recognizes a pattern of the obstacle by performing pattern recognition signal processing on the second image information; and a risk determining unit which determines a possibility of collision due to presence of the obstacle within the target distance by classifying the recognized obstacles according to whether or not the image-recognized obstacle is matched with the pattern-recognized obstacle.

Disclosed herein are an electronic parking brake system and a control method thereof. The electronic parking brake system includes brakes, a parking cable to apply braking force to the brakes, a motor to apply tension to the parking cable, a current sensor to sense current of the motor, and an electronic control unit to judge the braking force of the brakes based on the current of the motor, and to control driving of the motor based on the braking force. The electronic parking brake system senses the tension of the parking cable using the small-sized current sensor, thereby easily obtaining a space in which the current sensor is installed and thus reducing a product size of the electronic parking brake system. Further, the electronic parking brake system senses the tension of the parking cable using the inexpensive current sensor, thereby reducing manufacturing costs of the electronic parking brake system and reducing costs of an electronic parking brake system product and a vehicle provided with the same.

A solenoid valve for a brake system, which has a simplified configuration and can be easily manufactured with reduced manufacturing costs. The solenoid valve includes valve seat member integrally formed with a seat portion having a first orifice, an opening/closing member slidably installed in the valve seat member, the opening/closing member having an inner passage formed through the opening/closing member, an outer passage formed at an outer surface of the opening/closing member, a second orifice formed at one end of the opening/closing member, the second orifice having a smaller diameter than that of the first orifice, and a first opening/closing portion formed at the other end of the opening/closing member to open or close the first orifice, an opening spring to move the opening/closing member, for opening of the first orifice, a sleeve having a first end coupled to an outer surface of the valve seat member and a flange formed at the first end so as to be fixed to a modulator block, a valve core coupled to a second end of the sleeve, opposite to the first end of the sleeve, an armature slidably mounted in the sleeve, the armature having a second opening/closing portion to open or close the second orifice, and a restoring spring to press the armature toward the second orifice.
摘要:
This invention is about a novel Biomolecule Transducton Motif (BTM), Sim-2 peptide, which has a potential to transduce many biological response modifiers effectively into the cytoplasm, intracellular organelles or nucleus of prokaryotic or eukaryotic cells in vivo and in vitro, and the related technological methods using Sim-2 BTM. This Sim-2 BTM can be used for Drug Delivery System, development of new recombinant protein vaccines or DNA/RNA vaccines, gene and protein therapy, production of pharmacologically or medicinally useful proteins or pharmacomedicinal drug therapy.
