Abstract: A voltage drop Vzs is calculated based on an output current detection value Iac and a virtual synchronous impedance Zs or a corrected virtual synchronous impedance Zs?, and a value obtained by subtracting the voltage drop Vzs from an internal induced voltage Ef is output as a grid voltage command value Vac*. Zs calculation unit 7 limits an output current phase ? so that the output current phase ? is within an effective range by a phase limiter 12a, and calculates the corrected virtual synchronous impedance Zs? based on a limited output current phase ?, the internal induced voltage Ef, a grid voltage detection value Vac and a current limit value Ilim. Accordingly, in grid interconnection power conversion device that controls a virtual synchronous generator, it is possible to continue operation while suppressing an overcurrent and possess a synchronizing power generated by action or working of a virtual synchronous impedance.

Abstract: A window assembly comprises a substrate with a transparent layer that defines an area having a periphery. An outer region devoid of the transparent layer is defined adjacent the transparent layer along the periphery. A conductive element disposed on the substrate and comprises a first portion overlapping an area of the transparent layer and abutting and being in direct electrical contact with the transparent layer. The conductive element further comprises a second portion integrally extending from the first portion and disposed in the outer region. The periphery of the transparent layer delineates the first and second portions of the conductive element. The second portion has an area defining an enclosed slot. A feeding element couples to the conductive element for energizing the enclosed slot as a slot antenna. An energizing element couples to the conductive element for energizing the conductive element to implement a bus bar.

Abstract: A data management apparatus (10) is for managing data shared by a plurality of users. The data management apparatus (10) includes: an encryption processing unit (11) that encrypts the shared data; a coordinate acquisition unit (12) that, when one of the plurality of users has transmitted coordinates that have been pre-allocated thereto together with a request for decryption of the shared data, requests each of remaining users to transmit coordinates that have been pre-allocated thereto; and a decryption processing unit (13) that, when each of the remaining users has transmitted the coordinates that have been pre-allocated thereto, calculates a function from the coordinates transmitted by one user and the coordinates transmitted by the remaining users, and decrypts the encrypted shared data using a value obtained from the calculated function as a decryption key.

Abstract: A window assembly includes a substrate with an electrically conductive transparent layer that defines an area having a periphery. An outer region devoid of the transparent layer is defined adjacent to and along the periphery. An elongated antenna element is disposed in the outer region. A feeding element couples to the antenna element for energizing the antenna element. The area of the transparent layer defines at least two protrusions being spaced apart from one another and extending integrally from the area and into the outer region. The antenna element abuts and is in direct electrical contact with the at least two protrusions. The feeding element couples to the antenna element at a location between the at least two protrusions or at one of the at least two protrusions.

Abstract: To assist in regulation of an amount of agricultural produce collected at a collection/loading station, a collection amount regulation assist apparatus 10 includes a trend line setting unit 11 for setting, using a scheduled amount of the agricultural produce to be collected per day, a trend line indicating an ideal change in an amount of the agricultural produce to be collected from when collection of the agricultural produce is started until the collection ends, and an estimation unit 12 for obtaining a deviation ratio indicating a degree of deviation in an amount of the agricultural produce that has been collected from the trend line at a specific time point, and estimating whether or not the agricultural produce will be insufficient based on the obtained deviation ratio.

Abstract: A window assembly includes an electrically conductive transparent layer and an antenna element disposed on a substrate. The transparent layer has an area defining a periphery with a plurality of edges. An outer region devoid of the transparent layer is defined adjacent the transparent layer along the periphery. The antenna element includes a first antenna segment and a second antenna segment. The first antenna segment is elongated and disposed in the outer region and spaced from the periphery and extends solely along one edge of the periphery. The second antenna segment extends integrally from the first antenna segment towards the transparent layer such that the second antenna segment crosses a periphery of the transparent layer. A feeding element is coupled to the first antenna segment to energize the antenna element and the transparent layer such that the antenna element and the transparent layer collectively transmit and/or receive radio frequency signals.

Abstract: A sensor network includes a sensor management server which is mutually connected with many sensor terminals. The sensor management server includes: a key delivery module for transmitting a key update message to the respective sensor terminals; a communication volume detection module for detecting a communication volume used for transmitting the key update message; and a multiplicity determination module for specifying a numerical value as a multiplicity, which represents the lower limit number of key update messages transmitted to the respective sensor terminals, according to the detected communication volume. The multiplicity determination module specifies the multiplicity such that the communication volume for transmitting or retransmitting the key update message takes the minimum value, and the key delivery module transmits the key update message by using the minimum communication volume that corresponds to the specified multiplicity.
