Abstract:
Disclosed herein is a flexible network security system and method for permitting a trusted process. The system includes a port monitoring unit for extracting information about a server port being used through a network communication program, an internal permitted program storage for extracting information about a program for which communication is permitted by the firewall, and registering the extracted information, an internal permitted by the firewall, and registering the extracted information, an internal permitted port storage, if the port monitoring unit extracts the information about the server port being used using the program registered in the internal permitted program storage, registering the extracted information about the server port; and a device for making the firewall flexible, determining whether a destination port of a packet of inbound traffic has been registered in the internal permitted port storage, and if the destination port has not been registered, transmitting the corresponding packet to the firewall, and if the destination port has been registered, allowing the corresponding packet to bypass the firewall.

The present invention discloses a built-in type outdoor unit for an air conditioner to provide an efficient installation structure for installing the outdoor unit increased in capacity due to high air conditioning capacity in a built-in type. The built-in type outdoor unit includes a louver frame being fixedly installed on a rectangular space inner wall formed on an outer wall of a building, being divided into a suction area and a discharge area, including a plurality of louver blades in each area, and sucking and discharging air through gaps between the louver blades, an outdoor unit casing being formed in a rectangular parallelepiped shape, being fixedly installed on the inside bottom of the building to contact the louver frame, having its one surface facing the suction area and the discharge area of the louver frame opened and the other surfaces closed, and being divided into a suction unit and a discharge unit corresponding to the suction area and the discharge area of the louver frame, a compressor installed in the suction unit of the outdoor unit casing, for compressing a refrigerant gas supplied from an indoor unit through pipe lines, an air-cooled condenser installed in the suction unit of the outdoor unit casing, for condensing the refrigerant gas from the compressor, and a sirocco cooling fan installed in the discharge unit of the outdoor unit casing, for supplying external air to the air-cooled condenser through the suction area, and discharging heat exchanged air through the discharge area.
Abstract:
For supplying voltage to at least one main current consuming unit, a voltage supply unit provides the voltage to the at least one main current consuming unit at a supply node. In addition, an auxiliary current consuming unit conducts auxiliary current from/to the supply node for at least a predetermined time period before the at least one main current consuming unit begins to conduct current. Thus, voltage overshoot is prevented at the supply node.

The present invention discloses a built-in type outdoor unit for an air conditioner including: a louver frame being fixedly installed on a rectangular space inner wall formed on an outer wall of a building, being divided into a suction area and a discharge area, including a plurality of louver blades in each area, and sucking and discharging air through gaps between the louver blades; an outdoor unit casing being formed in a rectangular parallelepiped shape, being fixedly installed on the inside bottom of the building to contact with the louver frame, and having its one surface facing the suction area and the discharge area of the louver frame opened and the other surfaces closed; and means installed on at least one of the facing surfaces of the louver frame and the outdoor unit casing, for preventing external leakage of air between the louver frame and the outdoor unit casing. A compressor for compressing a refrigerant gas supplied from an indoor unit through pipe lines, an air-cooled condenser for condensing the refrigerant gas from the compressor, and a cooling fan for supplying external air to the air-cooled condenser through the suction area, and discharging heat exchanged air through the discharge area are installed in the outdoor unit casing.
Abstract:
The present invention discloses an apparatus and method for controlling an operation of an outdoor unit which can efficiently control the outdoor unit by mounting sensors on the outdoor unit. The apparatus for controlling the operation of the outdoor unit includes: a pressure sensor for sensing a pressure of refrigerants in an outlet of a compressor of the outdoor unit; a temperature sensor for sensing a temperature of the refrigerants in an outlet of a condenser; and a microcomputer for comparing the pressure from the pressure sensor and the temperature from the temperature sensor with optimal pressure and temperature ranges, and controlling operation conditions of at least a blast fan and the compressor in the outdoor unit to be inversely proportional to each other according to the comparison results.

Abstract:
A built-in type compressor/condenser unit for an air conditioner with an efficient installation structure for installing an increased capacity outdoor unit is provided. The built-in type compressor/condenser unit includes a louver frame installed on a rectangular shaped space formed on an outer wall of a building. The louver frame is divided into a suction area and a discharge area, each with a plurality of louver blades. The compressor/condenser unit casing is positioned proximate the louver frame, with the surface of the casing which faces the suction area and the discharge area of the louver frame open, and the remaining surfaces of the casing closed. A compressor, an air-cooled condenser, and a cooling fan are installed in the compressor/condenser unit casing.
Abstract:
A mobile communication device and method for identifying a counterfeit bill are provided. In the method, an InfraRed (IR) image of a bill is received, feature values are extracted from the IR image to represent edges, a binary image having displayed pixels and non-displayed pixels is generated based on the feature values, and a corrected image is generated by overlaying the binary image on a pre-stored real bill database and adjusting the binary image to match a predetermined area of the binary image matches to the predetermined area of the real bill database. A number of displayed pixels in the corrected image is counted, and whether the bill is counterfeit is based on the number of displayed pixels in the corrected image.
Abstract:
A method is provided for determining presence of a user's hand tremor or intentional motion during recognition of an image through photographing. Image sample blocks of a previous frame are detected by using an edge detecting method. A block distance between the detected image sample block of the previous frame and an estimated image sample block of a current frame is calculated. The calculated block distance is compared with a first threshold. The calculated block distance is compared with a second threshold when the calculated block distance is less than the first threshold.
Abstract:
There is provided a cochlear implant for improving the hearing ability of a patient suffered from hearing impairment comprising an internal receiving unit implanted into the body, which comprises a receiving part for receiving external signal, an active electrode and a reference electrode, characterized in that the active electrode is constructed with a single electrode wire having different thickness in at least two different regions. The active electrode of the internal receiving unit is inserted into a space formed at between the mastoid bone and the ear canal skin and end of the active electrode is inserted into the scala tympani of the cochlea and directly stimulates spiral ganglion. The cochlear implant provides easier implantation into the body and improved hearing ability at a lower cost.
