| 20100135187 | SYSTEM AND METHOD FOR CONTROLLING NETWORK CONFIGURATION FOR MOVING OBJECT - Provided are a system and a method for controlling a network configuration for a moving object. A monitoring device attached to the moving object, that is, a container loading a cargo, recognizes loading and moving circumstances of the container, construct a network with other containers according to the circumstances and performs connection/disconnection of the container to/from a network and maintenance of the connection until the container departs the origin and arrives at a destination through overland transportation and marine transportation. Accordingly, the state of the container is monitored, monitoring information is transmitted to a container administrator and the power of the monitoring device which constructs an optimized network with other monitoring devices according to container circumstances is saved. | 06-03-2010 |
| 20110068916 | LIFE SAVING SYSTEM WITH RFID TAG HAVING IP COMMUNICATION FUNCTION - Disclosed herein is a life saving system with an RFID tag having an IP communication function. The life saving system using RFID tags and a GPS comprises a plurality of RFID tags respectively attached to life jackets of survivors, respectively transmitting distress signals, and transmitting distress signals of other RFID tags when receiving the distress signals from the other RFID tags; smart points arranged in a distress area at predetermined intervals, including position information in the distress signals and transmitting the distress signals with the position information through satellite communication; and a control tower receiving the distress signals including the position information and transmitting a saving command. | 03-24-2011 |

| 20090102451 | METHOD AND STRUCTURE FOR VARIABLE PITCH MICROWAVE PROBE ASSEMBLY - A coplanar waveguide (CPW) probe includes at least one center probe element, each having a respective center probe contact point and at least one peripheral probe element, each having a respective peripheral contact point. The pitch between the at least one center contact point and the at least one peripheral contact point is adjustable. | 04-23-2009 |
| 20100045370 | TESTING OF TRANSIMPEDANCE AMPLIFIERS - Testing is performed on an amplifier wafer housing a transimpedance amplifier prior to packaging the transimpedance amplifier with an external photodetector, wherein the transimpedance amplifier includes a small, auxiliary, integrated silicon photodetector provided at the input of the transimpedance, in parallel with external photodetector attachment points. To test the transimpedance amplifier, the transimpedance amplifier is stimulated by optically exciting the small auxiliary photodetector, wherein the small auxiliary photodetector is excited using short wavelength light, whereby advantages such as higher efficiency may be obtained. The testing method includes placing the amplifier wafer in a testing system, probing the power and ground connections on the amplifier wafer, illuminating the small auxiliary photodetector on the amplifier wafer, and detecting the output of the transimpedance amplifier housed on the amplifier wafer. | 02-25-2010 |
| 20110193661 | Integrated Electromechanical Relays - Electromechanical relays and semiconductor structures and microelectromechanical systems including at least part of an electromechanical relay are presented. For example, an electromechanical relay includes an electrically conductive terminal within a printed circuit board, one or more electrically conductive contacts, and one or more magnetic actuators. The one or more magnetic actuators are respectively associated with the one or more electrically conductive contacts and each magnetic actuator includes (i) a magnetic core within at least one via extending through one or more layers of the printed circuit board, and (ii) an electrical coil around at least a portion of the magnetic core and within one or more layers of the printed circuit board. Activation of the one or more actuators causes electrical contact between the terminal and an associated one of the one or more electrically conductive contacts. | 08-11-2011 |
