| 20100087847 | BLOOD LANCET DEVICE - This invention relates to a blood lancet device that is used to collect a small quantity of blood from a human body. More specifically, it relates to a blood lancet device that: can control the depth of the lancet needle's penetration of the skin; can push the lancet to eject; can accurately collect blood by ensuring linear motion; and can reduce the pain involved in blood collection. | 04-08-2010 |

| 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 |

| 20090134699 | Signal Coupling Apparatus For Power Line Communications Using A Three-Phase Four-Wire Power Line - A signal coupling apparatus for power line communications includes an impedance matching transformer and a transmission mode control circuit for high data rate power line communications on a three-phase four-wire distribution line. Therefore, it is possible to improve the efficiency of power line communications, to minimize signal loss, and to construct an optimal high voltage distribution path. | 05-28-2009 |
| 20110051608 | WIRELESS LOCATION DETERMINATION SYSTEM AND METHOD - Disclosed herein is a wireless location determination system and method. | 03-03-2011 |
| 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 |
