Abstract: The present invention relates to a method and a system for recognition of objects near a ship by using a deep neural network to prevent a collision with the object by recognizing a neighboring object that may be risky to the ship sailing in a restricted condition such as a foggy environment. All object movements within a predetermined radius are detected and recognized so that collision accidents with objects on the sea in an environment such as fog caused by bad weather at sea can be prevented, and a risk alarm is notified to a captain when the object is detected so that collision accidents can be remarkably reduced. In addition, peripheral environments are detected by only installing a CCTV camera so that expenses can be reduced, human negligence can be prevented, and the system can be easily constructed to prevent collisions.

Abstract: Disclosed is a method of synthesizing graphene, wherein a Cu—Ni thin film laminate including a copper thin film and a nickel thin film formed thereon is placed in a chemical vapor depositor, brought into contact with a graphene precursor and subjected to chemical vapor deposition (CVD), thus synthesizing thickness-controlled graphene on the copper thin film, whereby the thickness of multilayer graphene can be easily and reproducibly controlled by adjusting only nickel thickness and CVD time, and a process window for obtaining reproducible results can be widened due to self-limiting properties whereby the maximum thickness of graphene is obtained after a certain synthesis time due to the thickness-controlled nickel thin film. Also, carbon atoms absorbed to the nickel thin film reach the copper thin film opposite thereto through internal diffusion of the metal laminate to thus grow graphene via surface-mediated reaction thereon, thereby improving the uniformity of synthesized graphene.

Abstract: Disclosed is a method of manufacturing multilayer graphene, including (a) contacting of a metal substrate with a nonmetal element, (b) reduction through heat treatment, and (c) chemical vapor deposition of a graphene precursor on the metal substrate containing the nonmetal element dissolved therein, thereby manufacturing multilayer graphene that is doped with the nonmetal element on the metal substrate. In the multilayer graphene thus manufactured, the number of graphene layers and the work function are simultaneously adjusted by controlling the concentration of doped nonmetal element in a thickness direction of graphene through interactions related to the reduction of the nonmetal element dissolved in a copper catalyst and the growth of graphene, and moreover, the stacking structure of graphene is maintained and the optoelectronic properties of multilayer graphene can be controlled by simultaneously regulating graphene growth and doping during the synthesis procedure without additional processing.

Abstract: Disclosed is a method of producing graphene, which includes bringing a metal catalyst into contact with hydrogen gas (Step a), bringing the metal catalyst in Step a into contact with at least one selected from among a hydrocarbon gas, nitrogen gas, and an inert gas (Step b), and forming graphene on the metal catalyst by bringing the metal catalyst in Step b into contact with hydrogen gas and a hydrocarbon gas (Step c), whereby the number of layers of graphene can be variously controlled as needed, regardless of the initial surface roughness of a metal catalyst layer, and also, the time required to form graphene can be shortened, thus reducing processing costs.

Abstract: An ink-supply device comprises: a body in which at least one housing space is formed and which is for housing at least one ink pack in the respective housing spaces; ink discharge tubes which are coupled to ink outlets of the respective ink packs; ink-supply tubes which are coupled to a cartridge; and a coupling members which are coupled between the ink-supply tubes and the ink discharge tubes linked to ink packs of the same color. A multiple loading type of ink-supply device is positioned below the cartridge such that excessive ink pressure does not occur in the cartridge and there is therefore the advantage that damage to the cartridge head can be prevented even without providing a separate damper.

Abstract: An optical pickup apparatus includes an objective lens that focuses light on an optical recording medium; an actuator that drives the objective lens in a direction of an optical axis of the objective lens toward or away from an optical recording medium in response to an input voltage applied to the actuator; an actuator driven distance sensor that senses a distance the actuator moves according to time or the input voltage applied to the actuator; an input voltage calculator that calculates an input voltage to be applied to the actuator that compensates for a hysteresis phenomenon that occurs during movement of the actuator based on the distance sensed by the actuator driven distance sensor; and a controller that controls operation of the actuator according to the input voltage calculated by the input voltage calculator.

Abstract: An optical pickup includes an optical module that detects an information signal and/or an error signal by radiating light to a recording medium and receives light reflected by the recording medium. The optical module includes a light source; an optical path changer that changes a path of light emitted from the light source; a main photodetector that receives light that is reflected off a recording medium back to the optical module to detect an information signal and/or an error signal; and a hologram element that generates an astigmatism of the light incident onto the optical module. Since most optical elements of the optical pickup except an objective lens are packaged in the optical module, the entire structure of the optical pickup can be simplified and the number of bonding points for fixing the optical elements of the optical pickup on a base can be reduced.

Abstract: A method of arranging an optical pickup system on a deck of an optical recording and/or reproducing apparatus, which enables detection of a tracking error signal using one photodetector based on a three-beam method and by a differential phase detection method. The optical pickup system includes a light source, a diffractive optical element which diffracts a light beam incident from the light source and splits the same into at least three beams, a plate-type beam splitter which changes a propagation path of the light beam, and a photodetector including at least one main photodetector having at least four sections and a plurality of sub-photodetectors. The optical pickup system is constructed so as to have a reflecting mirror redirect the propagation path of the light beam emitted from the light source toward a recording medium.

Abstract: A method for performing a preset listening operation for a radio broadcast using a microcomputer including a first tuner, a second tuner, a random access memory and a timer. The microcomputer stores data regarding a preset channel, a preset listening start time and a preset listening end time in the random access memory. If a main power is turned on, the microcomputer tunes the first tuner to an initial channel to listen to a general broadcasting program. The microcomputer then checks whether a preset listening function has been selected. If the preset listening function has been selected, the microcomputer detects the data from the random access memory. The microcomputer identifies the present time based on an output of the timer and then determines whether the checked present time is the same as the preset listening start time.
