  • Publication number: 20240097394
    Abstract: A light emitting sealed body includes: a housing which stores a discharge gas and is provided with a first opening to which first light is incident along a first optical axis and a second opening from which second light is emitted along a second optical axis; a first window portion which hermetically seals the first opening; and a second window portion which hermetically seals the second opening. The housing is formed of a light shielding material which does not transmit the first light and the second light. An internal space is defined by the housing, the first window portion, and the second window portion and the internal space is filled with the discharge gas. The first opening and the second opening are disposed so that the first optical axis and the second optical axis intersect each other.

  • Patent number: 11754900
    Abstract: A receiver for free-space optical communication includes a beam splitter, an imaging unit, a specifying unit, a light-receiving unit, and a controller. The beam splitter splits incident light into first and second light beams travelling in different directions. The imaging unit captures an image of the first light beam. The specifying unit extracts a signal light beam from the image of the first light beam and specifies a position of the signal light beam in the image. The light-receiving device receives the second light beam. The controller controls a blocker on the basis of the position of the signal light beam to allow only a limited portion of the second light beam to enter the light-receiving device and prevent a remaining portion of the second light beam from entering the light-receiving device. The limited portion of the second light beam includes the signal light beam.

  • Publication number: 20220307837
    Abstract: An inertial navigation device error correction system includes an inertial navigation device, a coordinate calculation device, and an error correction device mounted on each of aerial vehicles. The coordinate calculation device calculates coordinates of a second aerial vehicle with respect to a first aerial vehicle. The error correction device calculates azimuth and elevation angles of the second aerial vehicle based on first data on the first aerial vehicle, and azimuth and elevation angles of the second aerial vehicle based on second data on the second aerial vehicle. The error correction device corrects an error caused in the inertial navigation device of the first aerial vehicle, on the basis of angle measurement residuals that are differences between the azimuth and elevation angles of the second aerial vehicle based on the first data and the azimuth and elevation angles of the second aerial vehicle based on the second data.

  • Patent number: 7756927
    Abstract: If a control portion in a WAP terminal judges in step S1 that a session is established, the residual capacity of a memory portion is monitored at a predetermined time interval or any time interval in steps S2, S3. When the residual capacity of the memory portion is lower than a predetermined capacity, the control portion renews CPI information in step S5 and continues the operations of the steps S1 to S5 if the CPI information has not yet been renewed in step S4. If the CPI information has been renewed, the control portion continues the operations of the steps S1 to S4 without renewing the CPI information.
