Abstract: A power generation system and a power control device are provided that, even if there are provided a storage battery and a power conditioner as two independent devices, are capable of supplying electric power at least to the power conditioner in a power outage. The power generation system (1) includes the control device (41) connected to a second storage battery (42) so the that power conditioner (50) is fed with electric power by a power generation device (10), a commercial power grid (30) and a first storage battery (20).

Abstract: In a power control system, a control device acquires at least one of information about an external environment (result or predicted temperature) of a facility and information on a parameter associated with power consumption (production plan) in an internal environment of the facility and calculates a correlation between these pieces of information and actual consumed power. The control device predicts consumed power of the facility on the basis the correlation that is calculated and information such as predicted temperature and determines an upper limit set value of power supplied from an electrical grid to the facility on the basis of a result of the prediction. The control device supplies power charged in a storage battery to the facility when the consumed power of the facility exceeds the upper limit set value.

Abstract: A home theater includes a main unit section and at least one speaker section. The main unit section includes a communication section which receives an AV stream from an AV stream transmission device and via a communication network, a demux section which separates the AV stream into a video stream and an audio stream, a video processing means which processes the video stream so as to generate a video signal, an audio processing section which processes the audio stream so as to generate an audio signal, and an audio acquisition section which acquires an audio stream which includes at least a part of the audio of the AV stream. The communication section transmits the audio stream acquired by the audio acquisition section to the speaker section, via the communication network.

Abstract: The present invention comprises a communication means 10 that receives a packet; a detection means 20 that detects information, contained in the packet, that is known to both transmitting-side and receiving-side communication apparatuses; a comparison means 30 that compares multiple pieces of the known information detected by the detection means 20; a channel estimation means 40; a demodulation means 60; and a control means 70. In the case where it has been determined, as a result of the comparison performed by the comparison means 30, that the multiple pieces of known information are different, the control means 70 makes a channel estimation start instruction to the channel estimation means 40 and makes a channel estimation packet send request to a communication apparatus that sent the packet via the communication means 10, and the channel estimation means 40 performs channel estimation using the sent channel estimation packet based on the channel estimation start instruction from the control means 70.

Abstract: A communications apparatus includes: a timer for updating time information at a cycle longer than a cycle of a clock signal by a factor of n1 (n1>1 is a constant natural number); a frame generation section for generating frames each of which includes the time information; a transmission section; and a control section for instructing the modulation section to transmit the frames to other communications apparatus. The frame generation section sequentially transmits the generated frames to the transmission section. The control section instructs the transmission section to transmit the frames when a time longer than the cycle of the signal by a factor of n2 (n2 is a constant natural number) passes after the time information is updated.
