Abstract: An embodiment of the present invention relates to a combined accelerometer and gyroscope system. The combined accelerometer and gyroscope system includes a combined accelerometer and gyroscope for maintaining vibration of a mass body at a constant amplitude using an applied drive voltage, and detecting vibration signals in directions of an acceleration axis and an angular velocity axis. An acceleration axis vibration signal obtainment unit obtains the vibration signal in the direction of the acceleration axis. An amplitude maintenance control unit outputs an acceleration axis vibration maintenance control signal using the vibration signal. An acceleration axis driving input unit receives a voltage signal from the amplitude maintenance control unit and applies the voltage signal to the combined accelerometer and gyroscope. An angular velocity axis vibration signal obtainment unit obtains the vibration signal in the direction of the angular velocity axis.

Abstract: A pedal device for adjusting pedal effort includes a housing fixed to a car body, a pedal arm that is hinged about the housing, an elastic member that is disposed between the housing and the pivot end of the pedal arm and provides a return force to the pedal arm, a pedal effort adjusting unit that is movably disposed in the housing and has a sloped portion for adjusting a pre-compression force to the elastic member, and a pre-compression force setting unit that sets a fixed position of the pedal effort adjusting unit with respect to the housing and keeps a pre-compression force applied to the elastic member at a predetermined level. With this configuration, the pedal device can adjust the reaction force applied to the driver pressing the pedal corresponding to the driver's driving propensity, thereby improving the operability and reducing the fatigue of the driver's ankle.

Abstract: Provided is a method and apparatus for classifying geological materials using image processing techniques. The method and apparatus classify geological materials including stones, rock samples, and rock surfaces according to type and state by sequentially applying image processing techniques, such as a color space analysis, a granulometry analysis, texture parameter extraction and texture statistics extraction, to digital images of the geological materials. Since the method and apparatus extract quantitative figures that represent an entire image region by applying various image processing techniques, such as the color space analysis, the granulometry, the texture parameter extraction and the texture statistics extraction, to the digital images of the geological materials, the geological materials can be classified, which is not possible using a conventional image processing technique.

Abstract: The present invention relates to a multi-band antenna and, more particularly, to a sub multi-band antenna, in which a planer conducting part, which has a plurality of protruding portions, is inserted into a depression, which is formed on the surface of a body part formed through injection molding using a mold having a specific shape to surround first and second wire members, and the fitting depression of a fastening part, which is formed through the cutting or die casting of a metal material, and to a sub-band built-in chip antenna, in which sub radiation patterns having a predetermined length are formed on the interior surface of a body part, which is formed through injection molding using a dielectric material or is formed of a layered substrate a dielectric material.

Abstract: A presser foot drive structure of an embroidery machine, by which a vertically movable presser foot for preventing a sheet of cloth to be sewn from rising in a sewing operation is vertically moved inside a sewing head. The presser foot drive structure includes a presser foot drive holder, which is vertically slidable and is mounted on the outer circumference of a needle bar, which is vertically driven; a presser foot drive shaft, which is disposed parallel to the needle bar via the presser foot drive holder; and the presser foot, which is disposed at the lower end of the presser foot drive shaft and vertically reciprocates. It is possible to reduce the stroke of a presser foot so that it is smaller than that of a needle bar, enhance the supporting force for a needle bar, and reduce the shaking of a presser foot.

Abstract: Disclosed is an information protection system of an on-line service provider connected with customers' telephones through a telephone network for protecting important personal information of the customers from being leaked by tapping the customers' telephone lines, which includes an IVR system for collecting the customers' information-input patterns based on the customers' information-input signals received from the telephones and transmitting colored signals similar to the customers' information-input signals through the telephone network to the customers' telephone lines, and a control device for generating respective the colored signals similar to the customers' information-input signals based on the customers' information-input patterns, the colored signals being delivered to the IVR system. The IVR system transmits the colored signal to the customer's telephone line to scramble the customer's personal information being inputted.

Abstract: The information terminal device of the invention has a first function of displaying non-confidential data in a selectable manner on its display screen and, in response to the user's selection of the non-confidential data, showing the details of the non-confidential data. The information terminal device also has a second function of displaying confidential data in a selectable manner and, in response to the user's selection of the confidential data, showing the details of the confidential data. The first function is given as one normally selectable menu option and is activated by the user's selection of the corresponding menu. The second function is, however, not given as a normally selectable menu option and is triggered only by the user's series of operations of an operation unit in a preset sequence. No operation-related display appears on the display screen of the information terminal device during the user's series of operations of the operation unit.

Abstract: A natural oriental medicinal composition for the promotion of hair growth is provided. The oriental medicinal composition includes a black bean extract, a tangerine extract, a potato extract, a pine needle extract and a quartzite powder. Since the oriental medicinal composition includes crude drugs extracted from natural substances that can prevent hair loss, it is effective for hair growth and has ensured biostability. Particularly, the oriental medicinal composition allows newborn hair to grow in the form of stiff hair.
