  • Patent number: 12022247
    Abstract: An object of the present disclosure is to provide a data communication system, a computing apparatus, a data communication method, and a program, which are capable of highly reliable data transfer with low latency between computing apparatuses. The present disclosure achieves a highly reliable communication path by directly connecting computing apparatuses via an optical path and transmitting data through the optical path. Further, the present disclosure uses the optical path to achieve RDAM over wavelength transmission in which existing RDMA-enabled protocol stacks such as InfiniBand and TCP/IP/Ether are eliminated. The present disclosure eliminates the protocol stacks, enabling transfer with lower latency than in a case of “simply performing RDMA transmission over the wavelength path”.

    Abstract: An electrostatic atomizing system includes an air flow path having an air intake port and an air exhaust port, a humidifying device, an electrostatic atomizing apparatus, a first sensor, and a control unit. The humidifying device humidifies the air taken in through the air intake port. The electrostatic atomizing apparatus includes an electrode section operable to produce charged particulate water by causing the water in the air humidified by the humidifying device to condense on an electrode and applying voltage to that electrode. Moreover, the electrostatic atomizing apparatus exhausts air that contains the charged particulate water through the air exhaust port. The first sensor senses at least one of humidity and temperature of the air humidified by the humidifying device. The control unit determines, based on a sensing result of the first sensor, if there is a fault in the humidifying device or the electrostatic atomizing apparatus, and outputs the result of the determination.
