Abstract: A radiated electromagnetic wave estimation is performed by a computer. The estimation process includes: converting a circuit diagram of an electronic circuit board into a combination of a plurality of partial circuits; and predicting radiated electromagnetic waves from the electronic circuit board by using a prediction result of a radiated electromagnetic wave for each of the partial circuits obtained by the converting.

Abstract: According to one embodiment, an electronic device includes a connector, a first determination unit, and a first switching unit. The connector includes a plurality of terminals for being electrically connected to a peripheral device. The first determination unit determines whether or not a peripheral device compatible with an own device is connected to the connector, based upon an electrical state of a terminal that is not used in a terminal configuration of the own device among the plurality of terminals. The first switching unit is provided on a transmission line connecting the terminal of the connector and an electric circuit of the own device, electrically connects the transmission line when the first determination unit determines that the peripheral device compatible with the own device is connected, and electrically disconnects the transmission line when the first determination unit determines that a non-compatible peripheral device is connected.

Abstract: An information processing apparatus includes a wired electric power supply connector configured for connection with a wired electric power supply to receive electric power therefrom, non-contact electric power supply connector configured for electric coupling with a non-contact electric power supply to receive electric power therefrom, and a processor. The processor selects, for electric power supplied to each component of the information processing apparatus, one of the wired electric power supply and the non-electric power supply, wherein the wired electric power supply is selected at a time of startup of the information processing apparatus, and the non-contact electric power supply is selected if an operation state of the information processing apparatus or the non-contact power supply meets a predetermined condition. The processor controls the wired electric power supply connector and the non-contact electric power supply connector to supply electric power to each component based on the selection.

Abstract: A checkout counter is used for checkout transactions performed by a store clerk and a customer face to face. The checkout counter is set between a waiting position of the store clerk and a waiting position of the customer. A commodity-code input apparatus is arranged on a downstream side of a flow of commodities on which the store clerk takes a commodity planned to be purchased by the customer and moves the commodity. A commodity code input by the commodity-code input apparatus is used for settlement by a POS terminal. An information display is arranged further on an upstream side of the flow of commodities than the commodity-code input apparatus. Information for customers lining up to wait for their turns for checkout transactions is displayed on the information display.

Abstract: A guide vane protecting device for use in a hydraulic turbine. The device has a braking system having a first and a second braking members by which an initial braking power is imparted to a first control member interposed therebetween. The braking system further has a translational sliding mechanism which permits the translational sliding movement of the first braking member onto the first control member so so to cause a uniform increase of the braking force exerted by the braking members on the first control member, when a weakened pin incorporated in the protecting device is broken by an extraordinary force caused by, for example, jamming of foreign matter between adjacent guide vanes.
