20100060289 | System for Electrical Apparatus Testing - An easily implemented method of diagnosing both supply path, upstream, and load path, downstream, anomalies such as impedance events in machine or motor circuitry is accomplished by analyzing the across-the-line startup current and voltage time waveforms. No line of sight limitations exist and high accuracy exists. The techniques can be automated estimating poor contact resistance based on the voltage and current variation under a load change condition perhaps such as startup and/or shutdown of the load. Both, upstream and downstream problems from the point of voltage measurement can be monitored analyzing a load change condition. Additionally, downstream problems can be identified by using negative sequence current under steady state operation of the load. | 03-11-2010 |

20110260748 | APPARATUS AND METHOD FOR DIAGNOSING PERMANENT MAGNET DEMAGNETIZATION OF PERMANENT MAGNET SYNCHRONOUS MOTOR, AND APPARATUS FOR DRIVING PERMANENT MAGNET SYNCHRONOUS MOTOR - Provided are an apparatus and a method for diagnosing permanent magnet demagnetization of a permanent magnet synchronous motor. The apparatus includes a magnetic field generating unit, a stator current measuring unit, and a demagnetization diagnosing unit. The magnetic field generating unit generates magnetic fields of which directions are respectively parallel to a predetermined direction among a plurality of directions passing through a rotation axis of a rotor, on a plane vertical to the rotation axis of the rotor which is in a standstill. The stator current measuring unit measures currents which flow in a stator winding in correspondence with the respective generated magnetic fields. The demagnetization diagnosing unit compares a predetermined reference value and a comparison value which is calculated on the basis of the magnitudes of the stator winding currents which are measured in correspondence with the respective generated magnetic fields to diagnose demagnetization of a permanent magnet attached to the rotor. | 10-27-2011 |
20120057581 | SYSTEM AND METHOD FOR MANAGING SENOR NODE IN RFID/USN INFRASTRUCTURE AND GATEWAY SYSTEM USED THEREFOR - A sensor node management system in a Radio Frequency Identification/Ubiquitous Sensing Network (RFID/USN) infrastructure is provided, in which a sensor node has a local ID in a sensor network, a gateway receives, from the sensor node, node information including the local ID and an ID of a home gateway to which the sensor node initially belongs and registers the node information about the sensor node to a location information server, and the location information server registers and manages node information about sensor nodes within an area of the gateway. The location information server generates a global ID using the local ID and the ID of the home gateway, the global ID being recognized as an address of the sensor node by an Internet Protocol (IP) network. | 03-08-2012 |
20130006183 | CYLINDER PUMP - The present invention relates to a simple and small cylinder pump, which can stably supply a medical fluid regardless of the installed height of a liquid container or a blood bag. The cylinder pump includes an upper casing, and a lower casing coupled to the upper casing. An upper rotation member is rotatably inserted in the upper casing. A lower rotation member slidingly contacting the upper rotation member is rotatably inserted in the lower casing. An inner wall of the upper casing, a lower outer surface of the upper rotation member, an inner wall of the lower casing, and an upper outer surface of the rotation member constitute a cylinder having a single-tube shape.
