An air conditioning system includes: outdoor units; indoor units each communicating with any one of the outdoor units by a first communication method; and a central control device communicating with each of the outdoor units by a second communication method and controlling the outdoor units and the indoor units. One of the outdoor units generates, by using a first address used for communication performed using the first communication method, a second address used for communication performed using a second communication method, generates a second address for one or more of the indoor units by using a first address, and obtains second addresses from another outdoor unit and the central control device. The central control device obtains, from each of the outdoor units, second addresses of the outdoor unit and each indoor unit, and controls operations of the outdoor units and the indoor units by using the second addresses obtained.

Air conditioning system and communication method

An apparatus control system includes smart glasses worn by a user, a home electrical apparatus that is a target of control, and a controller that controls the home electrical apparatus. In the smart glasses, a sensor detects information including at least one of image information, motion information, biological information, or environmental information. A communicator transmits to the controller the information detected by the sensor. The controller, based on the information detected by the sensor, determines a recommended operation indicating operational content recommended with respect to a recommended apparatus, and transmits the determined recommended operation to the smart glasses. The communicator receives the recommended operation transmitted from the controller. The display displays a candidate group for selection of the home electrical apparatus along with a recommended operation received from the communicator.

Apparatus control system

A wind power generation system according to an embodiment includes a blade; a lightning protection device; an electric device; a voltage application mechanism; a first lightning arrester element; and a second lightning arrester element. The lightning protection device includes a receptor provided at the blade and guides a current of lightning to the ground from the receptor via a lightning conductor. The electric device is installed at the blade and includes a first electric conductor and a second electric conductor provided apart from each other. The voltage application mechanism applies a voltage between the first electric conductor and the second electric conductor. The first lightning arrester element has one end thereof electrically connected to the first electric conductor and has the other end thereof grounded. The second lightning arrester element has one end thereof electrically connected to the second electric conductor and has the other end thereof grounded.

Wind power generation system

A dispersion strengthened copper alloy containing a copper matrix, and dispersion particles dispersed in the copper matrix within a range of 0.5 to 6 vol %. In this alloy, an average diameter of a matrix region where the dispersion particles are not present is 0.3 .mu.m or less, and the total amount of solid solution elements contained in the copper matrix is determined such that, when this amount of the solid solution elements is added to pure copper, the electric conductivity of the matrix is lowered by 5% IACS or less.
