Abstract:
A wireless control device is provided with: a first wireless control unit that acquires first information including information indicating first positions of persons by using a first wireless method; a second wireless control unit that connects to wireless devices by using a second wireless method, and acquires second information that includes device identification information for identifying the wireless devices and information indicating second positions of the wireless devices; and an information control unit that selects the first position within a prescribed range from each second position, and specifies person identification information linked with the device identification information of the second position as the person identification information of a person present at the selected first position.
Abstract:
An optical element is formed of a composite material comprising a resin material and inorganic fine particles dispersed in the resin material. The resin material is composed of a first resin material comprising a compound having fluorine atom in its molecular structure, and a second resin material comprising a compound having carbonyl group and nitrogen atom in its molecular structure. A hybrid optical element includes a first optical element serving as a base material, and a second optical element layered on an optical surface of the first optical element. The second optical element is the above-mentioned optical element.

An optical element is formed of a composite material comprising a resin material and inorganic fine particles dispersed in the resin material. The resin material is composed of a first resin material comprising a compound having fluorene framework in its molecular structure, and a second resin material comprising a compound having carbonyl group and nitrogen atom in its molecular structure. A hybrid optical element includes a first optical element serving as a base material, and a second optical element layered on an optical surface of the first optical element. The second optical element is the above-mentioned optical element.
