Abstract: The present invention improves charging efficiency in a wireless power transfer device. A wireless power transfer device wirelessly transfers power by using inductive coupling to a charging target device placed in the vicinity of a charging pad. The wireless power transfer device includes an amplifier for performing power amplification, a series resonant circuit constituted by a resonant capacitor and a power transfer coil, and a foreign material detection unit for detecting a non-charging device, which is not a charging target, placed in the vicinity of the charging pad. The foreign material detection unit is constituted by a pick-up coil, bandpass filters, detector circuits and a control circuit. The foreign material detection unit detects an IC card which is the non-charging device by a signal component emitted through inductive coupling with the power transfer coil from the device placed in the vicinity of the charging pad when transferring power.

Abstract: A content transmission device has a first encryption process means that encrypts, by a digital communication interface, a digital content for transmission to a content reception device and encrypts a low-resolution content by a first encryption process; a second encryption process that encrypts a high-resolution content by a second encryption process; and a down-conversion means that down-converts the high-resolution content to the low-resolution content. The content transmission device receives, from a digital reception device, information related to an encryption process of the digital reception device. Then, if the digital reception device supports the second encryption process, the content transmission device transmits the high-resolution content as encrypted by the second encryption process. If the digital reception device does not support the second encryption process, the content transmission device down-converts the high-resolution content and encrypts, by the first encryption process, the down-converted content for transmission.

Abstract: An augmented reality (AR) display device includes a camera that captures a background image; a distance measuring sensor that measures a distance to a real object in the background image; a position and orientation sensor that detects the position of the camera and the shooting direction of the camera; a controller that recognizes the real object from the background image captured by the camera and associates the predetermined AR object with the recognized real object; a display displaying an image of the associated AR object; and a memory that stores data of the real object and the AR object associated with each other. The controller determines whether or not the real object is movable from the measurement result of the distance measuring sensor, and arranges the AR object according to the current position of the real object when the position of the real object associated with the AR object moves.
