20130066353 | SAFETY LANCET FOR DOUBLY PREVENTING REUSE THEREOF - Provided is a safety lancet including a reload double prevention structure for preventing a sliding block having a lancet needle from being reloaded to obtain blood, thereby fundamentally preventing reuse of the safety lancet. In addition, the safety lancet guides the sliding block to be straightly discharged without shaking, thereby minimizing pain when the lancet needle is inserted into a skin. The safety lancet includes an outer case forming a space part therein, an inner case sliding along the space part of the outer case, and having a through hole in a front end thereof, and a sliding block coupled to the inner case to straightly move along an inner portion of the inner case, and elastically supported within the outer case by a coil spring, wherein the sliding block comprises a lancet needle having an end protruding from a front end thereof, and a pair of loading hooks on both sides of a rear end thereof to engage with engagement protrusions of the inner case. As the inner case is moved rearward, when the sliding block is disengaged from a portion of the inner case, the sliding block is moved forward by elastic force of the coil spring to temporarily expose the lancet needle out of the inner case, and is then moved rearward to the inner case. | 03-14-2013 |

20110144682 | SAFETY LANCET FOR PREVENTING REUSE - A safety lancet for preventing reuse is provided, including an upper and lower case, moving block, guide, pressing plate, seating recess, and resilient spring. The upper case and a lower cases are coupled together with a space therein and a through-hole at the front to expose a lancet needle. The moving block is movable within the cases. with the lancet needle at the front. The guide is positioned behind the moving block within the cases and includes an anti-reverse ledge to selectively restrict reverse movement for reloading of the moving block. The pressing plate is pivotably mounted to the upper case and includes a stopper on which the moving block is caught, and a pressing projection for pressing the guide. The seating recess is defined in a bottom of the lower case, in which the guide descends and is seated. The resilient spring supports the rear of the moving block. | 06-16-2011 |

20110142174 | APPARATUS AND METHOD FOR DETECTING IMPULSE SIGNAL AND IMPULSE SEQUENCE - Disclosed herein is an apparatus and method for detecting an impulse signal or impulse sequence to realize wireless real-time location system application in a multipath fading environment. The apparatus includes a band-pass filter, an RF analog unit, and a signal processing base-band unit. The band-pass filter removes unnecessary frequency bands from impulse signals received through a receiving antenna. The RF analog unit detects the envelope of the impulse sequence deprived of the unnecessary frequency bands and based on a multipath, and outputs a digital signal regarding the envelope based on a leading edge of the envelope. The signal processing base-band unit performs low-speed 1-bit sampling and then output data, and, if frame synchronization has been found or a ranging command has been detected, performs high-speed 1-bit sampling and then calculates and outputs the propagation time of the impulse signals. | 06-16-2011 |
20120286584 | SPACE-ADAPTIVE WIRELESS POWER TRANSFER SYSTEM AND METHOD USING EVANESCENT FIELD RESONANCE - A magnetic resonance wireless power transfer method according to an aspect of the present invention includes transmitting power from a source coil to the Tx resonant coil using a magnetic induction method, transmitting the power from the Tx resonant coil to an Rx resonant coil, having a resonant frequency identical with that of the Tx resonant coil, via magnetically-coupled resonance, and transmitting the power from the Rx resonant coil to the device coil of an electronic device using the magnetic induction method. The Tx resonant coil and the Rx resonant coil are arranged at a right angle or a specific angle of inclination relative to each other. | 11-15-2012 |
20130134794 | WIRELESS POWER TRANSMITTER AND METHOD OF TRANSMITTING POWER THEREOF - Disclosed are a wireless power transmitter and a method of transmitting power thereof. The wireless power transmitter to wirelessly transmit power to a wireless power receiver includes a transmission coil to receive power from a power supply apparatus, and a transmission resonance unit to transmit the power received therein from the transmission coil to the wireless power receiver using resonance. The transmission resonance unit includes an inner loop, and an outer loop connected to the inner loop while surrounding the inner loop. | 05-30-2013 |
20130241774 | WIRELESS POSITIONING SERVER USING CLOCK OFFSET CALIBRATION AND WIRELESS POSITIONING METHOD USING THE SAME - A wireless positioning server using clock offset compensation and a wireless positioning method using the same. The wireless positioning server using clock offset compensation estimates a precise position of a tag requiring position information by effectively predicting information regarding a distance between a beacon for performing positioning and the tag requiring position information. An error in the positioning estimation result due to a clock offset is minimized by measuring a relative clock frequency ratio between beacons and by compensating for clock frequencies of the beacons when a distance between a beacon and a tag is estimated. | 09-19-2013 |
