Abstract: An information input device worn on a user's body or finger, an information processing device and an information input method are provided. The information input device which is capable of being worn on a user's body includes a distance sensing unit which senses changes in distance between a predetermined portion and another predetermined portion of the user's body according to the extent of bending of the user's body joint; and a signal processing unit which determines and processes information input items from the distance sensed by the distance sensing unit.

Abstract: An apparatus for turning a page and a method for turning a page in a personal information terminal including a finger movement sensing unit which senses a trace of a user's finger movement, a characteristic extracting unit which extracts a characteristic of the trace sensed by the finger movement sensing unit, a suitability determining unit which determines a suitability of the characteristic extracted by the characteristic extracting unit for turning a page, and a page turning unit which outputs a turned page to an output device if the characteristic is determined to be suitable for turning a page as a result of the determination of the suitability determining unit. Therefore, it is possible to improve a user's convenience by making the user feel comfortable as if the user turns a page of an actual paper book.

Abstract: A circuit board having a dielectric substrate, a grounding surface formed on at least one surface of the dielectric substrate, and transmission lines formed on one surface of the dielectric substrate for transmitting electrical signals. At least a portion of each of the transmission lines is isolated from an upper surface of the dielectric substrate to reduce the effective permittivity between the transmission lines and the grounding surface and a dielectric loss therebetween. In a method of manufacturing a circuit board, first, a sacrificial layer is formed on a dielectric substrate. Next, supporter patterns and transmission line patterns are formed by patterning the sacrificial layer. Then, supporters and transmission lines are formed in the supporter patterns and transmission line patterns, respectively. Following this, the sacrificial layer is removed so that the transmission lines are isolated from the upper surface of the dielectric substrate.

Abstract: An input device for computer games is provided. The input device includes an inertia sensor for sensing the movement of the input device, at least one trigger button, and a signal processor for formatting signals output from the inertia sensor and the at least one trigger button and transmitting the formatted signals to a computer.

Abstract: A method for pointing at information in a multi-dimensional space is provided. The method includes the steps of (a) setting a portion of a full screen including a plurality of pieces of information, as a pointing screen; (b) determining whether desired information to be pointed at is included in the set pointing screen; (c) when it is determined that the desired information is not included in the pointing screen, moving the pointing screen so that the desired information can be included in the pointing screen; and (d) pointing at the desired information included in the pointing screen when it is determined that the desired information is included in the pointing screen or after step (c). At least one of steps (a), (c), and (d) is performed by a user's motion in at least one direction selected from up, down, forward, backward, to the left, and to the right.

Abstract: An information input method using a wearable information input device is provided. The information input method using a wearable information input device, which is worn on predetermined body parts of a user and has sensors for sensing motions of the predetermined body parts on a plane or in a space, includes selecting a key group including a desired key corresponding to information that the user desires to input by moving a first predetermined body part, and selecting the desired key from the selected key group by moving a second predetermined body part. Accordingly, the user can easily and quickly select a key on an information screen externally, and areas overlapped by the information screen in a monitor can be minimized.

Abstract: An information input method of a computer system having a virtual keyboard includes detecting motion information of a user's hands and fingers, determining the locations of the user's hands and fingers by interpreting the detected motion information, displaying an input apparatus having a predetermined shape on the virtual keyboard of a screen based on the determined locations of the user's hands and fingers, and applying force to a finger corresponding to the location where information is input, if the input information is input by the displayed input apparatus.

Abstract: A monolithic microwave integrated circuit (MMIC) includes a semiconductor substrate, active and passive devices formed on the semiconductor substrate, a dielectric layer formed to cover the active and passive devices on the semiconductor substrate, and a ground plane formed on the dielectric layer to ground the active device through the dielectric layer.
