Abstract: An information processing device includes an acquisition unit that acquires information related to a charging device that receives power from a power supply facility and supplies the power, the charging device being separated from the power supply facility; a determination unit that determines permission or non-permission of the power supply of the charging device based on the information related to the charging device; and a transmission unit that transmits information related to a determination result of permission or non-permission of the power supply to the charging device or another device that controls the charging device.

Abstract: This communication device has a phase-modulation spatial light modulator; and a control unit which causes, during one frame time interval, the phase-modulation spatial light modulator to operate with first and second operation patterns. In a predetermined period within the one frame time interval, the first operation pattern includes a first light transmittable interval during which first signal light can be output, and a first pause interval during which the first signal light cannot be output whereas the second operation pattern includes a second light transmittable interval during which second signal light can be output, and a second pause interval during which the second signal light cannot be output. The first and second light transmittable intervals are each longer than a half of the predetermined period. The second pause interval is present within the first light transmittable interval, and the first pause interval is present within the second light transmittable interval.

Abstract: This communication system includes: at least one transmitter which emits signal light; and a receiving device which receives the signal light. The receiving device is provided with: a control unit which generates a phase image on the basis of position information indicating a position of the transmitter, and combines a virtual lens image with the phase image to generate a composite image; a phase-modulation spatial light modulating element which receives the composite image and diffracts and collects signal light; and a detector which receives the diffracted and collected signal light.

Abstract: [Problem] To provide: a wireless communication device capable of preventing, on the basis of a transmission signal, the wireless communication device from being identified as other wireless communication devices with a simple configuration; a wireless communication system; a wireless communication method; and a wireless communication program. [Solution] An amplifying unit 11 generates a transmission signal by amplifying a signal. A processing unit 12 processes the signal and/or the transmission signal. A storage unit 13 has a plurality of parameters stored therein, said parameters being to be used for the purpose of the processing. A parameter selection unit 14 selects one parameter from among the parameters stored in the storage unit 13. Then, the processing unit 12 performs the processing on the basis of the one parameter thus selected by the parameter selection unit 14.
