Patent application number	Description	Published
20110078574	SYSTEMS AND METHODS FOR THE CONFIGURATION AND MANAGEMENT OF INTELLIGENT ELECTRONIC DEVICES - According to some embodiments, data may be received from a plurality of intelligent electronic devices (e.g., such as a set of protective relays). For each intelligent electronic device, status information may be stored based on the received data. Moreover, the status information may be displayed via a graphical user interface for the plurality of the intelligent electronic devices. The stored status information may also be transmitted to a remote central server via a communication network.	03-31-2011

20090259149	POWER SUPPLY APPARATUS FOR OPERATION - A power supply apparatus for operation for outputting power to a surgical instrument includes a resonant frequency detection section for detecting a resonant frequency which minimizes the impedance of the surgical instrument, and an abnormality detection section for detecting whether or not a value of the resonant frequency or a variation amount of the resonant frequency per unit time exceeds a predetermined numerical range or a reference variation value. The predetermined numerical range or the reference variation value is set on the basis of a value and a variation amount of the resonant frequency corresponding to a temperature change of the surgical instrument. By detecting an abnormality in this manner, the surgical instrument can be prevented from being broken.	10-15-2009
20090259221	POWER SUPPLY APPARATUS FOR OPERATION - A power supply apparatus for operation for outputting power to a surgical instrument includes an impedance detection section for detecting the impedance of the surgical instrument in the output, and an abnormality detection section for detecting an abnormality according to whether or not a variation value of the impedance per unit time exceeds a predetermined first impedance variation value. The abnormality detection section further detects an abnormality according to whether or not a variation value of a resonant frequency per unit time exceeds a predetermined threshold. The abnormality is detected in this manner, whereby it is possible to prevent the surgical instrument from being broken.	10-15-2009
20090259243	POWER SUPPLY APPARATUS FOR OPERATION - A power supply apparatus for operation for outputting power to a surgical instrument includes a phase difference detection section for detecting a phase difference between an output voltage and an output current in the output, and an abnormality detection section for detecting an abnormality according to whether or not a period of time for which the phase difference deviates from a predetermined normal value range exceeds a predetermined period of time. Further, a power supply apparatus for operation for outputting power to a surgical instrument includes a phase difference detection section for detecting a phase difference between an output voltage and an output current from the power in the output, and an abnormality detection section for detecting an abnormality according to whether or not a variation value of the phase difference per unit time exceeds a predetermined threshold. By detecting the abnormality in this manner, the surgical instrument can be prevented from being broken.	10-15-2009
20090259244	POWER SUPPLY APPARATUS FOR OPERATION - A power supply apparatus for operation for outputting power to a surgical instrument includes a temperature detection section for detecting a temperature of the surgical instrument, and an abnormality detection section for detecting an abnormality of the surgical instrument on the basis of the detected temperature. The temperature detection section detects the temperature by measuring the electric capacitance of the surgical instrument or directly measures the temperature of the surgical instrument by using a temperature measurement device. More specifically, the abnormality detection section detects the abnormality according to whether or not a temperature variation amount of the surgical instrument per unit time exceeds a predetermined threshold. Further, when the abnormality detection section detects an abnormality, the abnormality detection section stops the output of the power to the surgical instrument. By detecting an abnormality in the manner described above, the surgical instrument can be prevented from being broken.	10-15-2009
20090259423	POWER SUPPLY APPARATUS FOR OPERATION AND RESONANT FREQUENCY SEARCHING METHOD - A power supply apparatus for operation supplies a drive signal of a resonant frequency to a surgical instrument to drive the instrument. A recognition section recognizes a surgical instrument connected to the power supply apparatus. A setting section sets a frequency scanning condition according to the surgical instrument recognized by the recognition section. A scanning section scans for the resonant frequency of the surgical instrument on the basis of the frequency scanning condition set by the setting section.	10-15-2009
