Abstract: An X-ray imaging apparatus includes an X-ray generation apparatus including an X-ray generation tube having an electron gun and a target configured to receive an electron beam from the electron gun to generate X-rays, a support structure supporting the tube, and a deflector configured to deflect the electron beam, an X-ray detector configured to detect the X-rays from the X-ray generation apparatus, and a control apparatus configured to control the X-ray generation apparatus. The support structure supports the tube to permit at least the target to be pivoted in a state in which the deflector is fixed, and the control apparatus determines, based on use amount of the X-ray generation apparatus and/or change of the X-rays generated by the X-ray generation apparatus, whether it is necessary to pivot the target.

Abstract: A VGI system includes a plurality of BEVs, a plurality of pieces of EVSE, and a server. The server determines whether the BEV exchanges electric power with a power grid with the use of second EVSE provided in a second area, the second area being different in manner of management of power supply by the power grid from a first area where predetermined first EVSE is provided, the first EVSE being normally used by the BEV. When the server determines that the BEV exchanges electric power with the use of the second EVSE and when the second area is higher than the first area in contribution to DR in exchange of electric power by the BEV, the server grants an incentive higher than in exchange of electric power with the power grid with the use of the first EVSE.

Abstract: An operation management server manages a vehicle equipped with a battery able to store regenerated electric power. The operation management server includes: a processor that generates a message to be transmitted to the vehicle; and a storage that stores traveling histories of a plurality of vehicles. The processor estimates a transition in a power storage amount of the battery on a planned travel route of the vehicle based on a travel plan of the vehicle and the travel histories of the vehicles. The processor generates the message for proposing execution of external power supply from the battery to an outside of the vehicle before the power storage amount reaches a predetermined amount, when an estimation is made that the power storage amount will exceed the predetermined amount on the planned travel route.

The control unit is configured to, when the electrified vehicle accedes to a request to perform the power control, generate a program command to reduce display of advertisements on the terminal as compared to when the electrified vehicle does not accede to the request to perform the power control.

Abstract: A power management apparatus includes a communication unit (acquisition unit) that acquires information about supply and demand of electric power for a power bank (power storage device), and a processor (controller) that controls electric power received by an electric vehicle from the power bank. The processor sets a power exchange ratio of electric power received from the power bank to electric power supplied to the power bank, depending on the supply and demand of electric power. The processor determines an amount of electric power to be received by the electric vehicle from the power bank, based on an amount of electric power supplied from the electric vehicle to the power bank, and the power exchange ratio.

Abstract: A speech is recognized using ACF factors extracted from running autocorrelation functions calculated from the speech. The extracted ACF factors are a W?(0) (width of ACF amplitude around zero-delay origin), a W?(0)max (maximum value of the W?(0)), a ?1 (pitch period), a ?1 (pitch strength), and a ??1/?t (rate of the pitch strength change). Syllables in the speech are identified by comparing the ACF factors with templates stored in a database.
