摘要： When an instruction from the user is received or when an event occurs and the head mounted processing apparatus is terminated, a key content pair information register is configured to associate a state of content at the time of the event occurrence with a registration key obtained from an image of a camera at the time of the event occurrence to store them in a memory as key content pair information. When the head mounted processing apparatus is activated, a key content pair restorer is configured to determine whether an image of the camera at the time of apparatus activation is made conformity with the registration key or not on the basis of the key content pair information, and restore the state of the content corresponding to the registration key made conformity with the image in a case where the image is made conformity with the registration key.

摘要： In a power supply system for wirelessly supplying power between a power transmission device and a power reception device, the power transmission device includes a power transmission unit for generating supply power and transmitting the generated supply power to the power reception device; a power transmission side magnet for alignment with the power reception device; a magnetic sensor for detecting a magnetic force from a power reception side magnet provided in the power reception device; and a control unit for controlling the power transmission device. The power reception device includes: a power reception unit for receiving the supply power supplied from the power transmission device; the power reception side magnet for alignment with the power transmission device; and a control unit for controlling the power reception device. When the power transmission device and the power reception device are in close contact with each other, power is wirelessly transmitted from the power transmission unit to the power reception unit in a state in which the power transmission unit and the power reception unit are aligned by an attractive magnetic force between the power transmission side magnet and the power reception side magnet. When the power transmission device and the power reception device are apart from each other, the control unit of the power transmission device starts or stops power transmission from the power transmission unit according to a magnetic force detection signal from the power reception side magnet detected by the magnetic sensor.
