  • Patent number: 10080127
    Abstract: A first communication terminal, unconnected with a communication network, searches for a second communication terminal existing around the own communication terminal. In the communication network, one of communication terminals functions as a master having a function of an access point and the rest of the communication terminals function as slaves of the master. Among the one or more second communication terminals found through the search, the first communication terminal determines a second communication terminal, in which information included in a communication message received from the second communication terminal shows that it is a connected master terminal which is a terminal connected with the communication network and functions as the master, to be a connection counterpart. Then, the first communication terminal configures a network with the determined connection counterpart.

  • Patent number: 10078258
    Abstract: A laser light source (110) emits a light that is a laser light. A projection control unit (120) controls, on the basis of image information, the intensity distribution of a light to be projected, thereby generating an image. A projection unit (130) projects the light as controlled by the projection control unit (120). A measurement unit (140) measures the intensity of the light projected from the projection unit (130). A distribution calculation unit (150) calculates, on the basis of the image information, the intensity distribution of the light to be projected from the projection unit (130). A selection unit (160) selects that partial evaluation area of the image which is to be used for determination. A determination unit (170) determines, on the basis of both the light intensity distribution, in the evaluation area, calculated by the distribution calculation unit (150) and the light intensity, in the evaluation area, measured by the measurement unit (140), whether any abnormal projection has occurred.
