| 20080236866 | MULTIFUNCIONAL CONNECTION CORD FOR MULTIMEDIA DEVICE - A multifunctional connection cord having data and power interfaces for a personal computer and audio interface for an earphone is provided. A multifunctional connection cord of the present invention includes a stem; an audio plug mounted to protrude from one side of the stem for establishing audio signal lines with a multimedia device; a data/power connector mounted near the audio plug to protrude from the stem for establishing data lines and power charge lines with an external device; a USB connector electrically connected to the audio plug and the data/power connector through a cable by means of the stem; and a socket holder mounted on one side of the USB connector and having an audio socket for receiving an audio plug. | 10-02-2008 |
| 20090004982 | METHOD AND SYSTEM FOR DATA COMMUNICATION USING A BODY - A portable device for data communication using a body as a conductor to transmit data to a receiver, the portable device includes a data receiving unit to receive data, a controller unit to control processing of data to be transmitted, a current limiting circuit to limit a current of a signal corresponding to the data to be transmitted to a predetermined value, and transmitting electrodes connected to the current limiting circuit and to contact the body to transmit the signal having the current of predetermined value to the receiver. | 01-01-2009 |
| 20090107777 | PARKING BRAKE DEVICE OF DISK BRAKE - Disclosed is a parking brake device of a disk brake. The parking brake device includes a caliper housing including a finger unit and a body part to push pad plates, which are installed at both sides of a disk, to closely make contact with the disk, a cylinder provided in the body part of the caliper housing, a piston slidably provided in the cylinder to move the pad plates toward the disk by using driving force generated from hydraulic pressure or mechanical thrust force, a cam unit provided at a rear portion of the cylinder to transform rotation motion of a parking brake lever into linear motion of the piston, and including an operating shaft, a ramp, and a ball, and a push rod which delivers linear motion of the cam unit into the piston. A flange part of the push rod is coupled to an open front end of the ramp having a cylindrical shape by using grooves or protrusions, so that the push rod is easily prevented from rotating. | 04-30-2009 |
| 20100168759 | MICRO MANIPULATOR FOR ELECTRODE MOVEMENT IN NEURAL SIGNAL RECORDING - This disclosure relates to a micro manipulator having a simple structure and having high possibility of recording a biological signal of a neuron at a desired position by improving positioning resolution of an electrode disposed adjacent to a subject's brain neuron or an electrode holder attached with the electrode. The micro manipulator according to the disclosure includes: a motor which includes a shaft and a vibration portion; a mobile which is connected to the shaft so as to be movable along the shaft; and a frame which supports the motor, wherein an electrode is connected to the mobile in a direction parallel to a longitudinal direction of the shaft, and wherein when the mobile moves linearly in accordance with a vibration of the shaft due to the vibration portion, the electrode moves linearly. | 07-01-2010 |
| 20110139704 | BLOOD DIALYZING APPARATUS - A blood dialyzing apparatus includes a blood dialyzing filter for dialyzing blood by using a pressure difference between the blood and a dialysis solution, and a supplying means for supplying the blood and the dialysis solution to the blood dialyzing filter in order to alternately generate a state where a blood pressure is higher than a dialysis solution pressure and a state where the dialysis solution pressure is higher than the blood pressure. The blood dialyzing apparatus dialyzes a large volume of blood in a short period of time without increasing the size of the blood dialyzing filter and simply controls the volume of the dialyzed blood by adjusting the supply pressures of the blood and the dialysis solution. | 06-16-2011 |
| 20110190859 | POLYMER LINEAR ACTUATOR FOR MICRO ELECTRO MECHANICAL SYSTEM AND MICRO MANIPULATOR FOR MEASUREMENT DEVICE OF CRANIAL NERVE SIGNAL USING THE SAME - A polymer linear actuator for a micro electro mechanical system (MEMS) and a micro manipulator for a measurement device of cranial nerve signal using the same are provided. The polymer linear actuator has first and second bodies positioned spaced apart to a distance from each other, and one or more pairs of V-type moving units connecting the first and second bodies together, wherein the moving units in pair are opposed to each other to convert a rotation motion of the respective moving units into a linear motion, thereby causing the first and second bodies to move linearly. | 08-04-2011 |
| 20110214927 | BIDIRECTIONAL MOVING MICRO-ROBOT SYSTEM - Disclosed herein is a bidirectional moving micro-robot system. The bidirectional moving micro-robot system has a first body having a plurality of legs foldably/unfoldably connected thereto, a second body having a plurality of legs foldably/unfoldably connected thereto and a connection member having both end portions respectively connected to the first and second bodies. In the bidirectional moving micro-robot system, the length of the connection member exposed between the first and second bodies is extended or contracted. | 09-08-2011 |
| 20110286722 | METHOD AND SYSTEM FOR DATA COMMUNICATION USING A BODY - A portable device for data communication using a body as a conductor to transmit data to a receiver, the portable device includes a data receiving unit to receive data, a controller unit to control processing of data to be transmitted, a current limiting circuit to limit a current of a signal corresponding to the data to be transmitted to a predetermined value, and transmitting electrodes connected to the current limiting circuit and to contact the body to transmit the signal having the current of predetermined value to the receiver. | 11-24-2011 |
